Description

  The present invention relates to a head-mounted image display device, and more particularly to a head-mounted image display device that can easily perform operations such as production of stereoscopic images and images of games, etc. with a small-scale device. It is.

  Conventionally, as an example of the work flow in the case of producing a moving image using, for example, a stereoscopic video, as shown in FIG. 40 in the drawings attached to the present application, first, object data (basic data) is created as a process P1. In the next process P2, an animation work based on the data created in the process P1, that is, a moving picture creation work is performed. Then, in the next process P3, the actual rendering work based on the moving picture data created in the process P2, that is, the moving picture creation work as a finished product is performed. This moving picture data is recorded in the next process P4, that is, recorded. The operation of recording on a medium is common.

  As the work performed in the object data creation step (process P1) for stereoscopic video production, for example, as shown in FIG. 43, two imaging devices (cameras L and R) are arranged side by side, and each imaging device is arranged. Thus, an operation of recording a pair of images captured by the above-described recording devices using independent recording devices (video decks L and R) is performed. Then, the pair of recorded videos is used as basic data, and a moving image creation work is performed based on the basic data.

  In addition, a pair of videos, that is, a video to be reproduced for the left eye and a video to be reproduced for the right eye are created for each frame by a computer or the like (so-called computer graphics (CG)). An operation of recording a pair of images by independent recording devices is performed as an object data creation process. Then, using this pair of videos (CG) as basic data, a moving image creation work is performed based on the basic data.

  Here, a stereoscopic image using binocular parallax will be briefly described below with reference to FIGS. 41 and 42 in the drawings attached to the present application.

  In FIG. 41 (a), the left-eye video indicated by the symbol L and the right-eye video indicated by the symbol R are obtained by observing a single object (a spherical object in FIG. 41) separately by the left eye and the right eye of the observer. It is an image of object data that is imaged or created in the case of the case.

  When the left-eye video L and the right-eye video R are independently reproduced for the left and right eyes of the observer, as shown in FIG. 41 (b), the left and right eyes of the observer are The virtual image plane of the display means (LCD or the like) of the playback device is viewed. At this time, the object data on the virtual image plane of the display means, that is, the two object data of the left-eye video L and the right-eye video R are displayed. Can be viewed as a single object image (this phenomenon is called “fusion”).

  Further, in order to make an object appear to jump out toward the front, a pair of object data of a left eye image L and a right eye image R as shown in FIG. In this case, the object data of the left-eye video L and the right-eye video R are positioned on the virtual image plane of the display means (LCD or the like) as shown in FIG. As a result, the object image that is viewed as a single image by the left and right eyes of the observer is observed so as to be in a position where it jumps forward by the amount indicated as “jump amount” in FIG. It becomes.

  Conventionally, the imaging or creation of object data performed during the above-described stereoscopic video production work is performed by imaging two independent imaging devices, that is, images for the left eye, as shown in FIG. A camera L and a camera R that captures a right-eye image are arranged side by side facing the subject, and a pair of images (left-eye image L and right-eye image) captured by the respective cameras L and R are arranged. R) are recorded on separate recording media by two independent recording devices, that is, a video deck L for recording the left-eye video L and a video deck R for recording the right-eye video R, respectively. Is the basic data.

  43 indicate the field angles by the imaging optical systems of the cameras L and R, that is, the range in which the images can be captured. The field angle La of the camera L and the field angle Ra of the camera R, respectively. Are set to be substantially equal to each other, and both the view angles La and Ra are set so as to almost overlap. Then, by providing this overlapping portion, stereoscopic vision can be obtained within this range.

  In addition, conventionally, confirmation of a stereoscopic image performed when a moving image is created based on object data (basic data) captured or created and recorded as described above has been conventionally performed as follows. Yes.

  That is, as shown in FIG. 44, for example, the left-eye video L and the right-eye video R are simultaneously reproduced by two independent video decks L and R while ensuring a synchronous relationship, and the respective video signals are captured by the camera. The images L and R are output to L and R, and the images L and R are respectively viewed by the left and right sides of the observer by a finder portion formed by, for example, a liquid crystal display (LCD) or the like. The 3D image is confirmed at the time of the above-mentioned image production by displaying the image independently of the eyes.

  As described above, in the object data creation process (P1), the animation work process (P2), the actual rendering process (P3), and the like during the stereoscopic video production work as described with reference to FIG. Each time there is a request to proceed with production while confirming.

  As the confirmation items of the stereoscopic video performed at the time of this video production, for example, how much stereoscopic effect is appropriate, whether the feeling of force is sufficient, or the pair of left and right images is not in a parallax that cannot be fused. There are various items such as whether the balance of the pop-up amount in the front-rear direction of the screen is appropriate when connecting scenes when editing each video.

  The above-mentioned requirement, that is, the requirement to proceed with the work while confirming at the time of video production, is the case where the produced stereoscopic video is used in, for example, a game, amusement, entertainment, etc. This is strongly demanded when you want to get the results.

  On the other hand, various proposals have hitherto been made for imaging devices (systems) for capturing stereoscopic images.

  For example, a stereoscopic imaging device disclosed in Japanese Patent Application Laid-Open No. 7-75134 discloses a camera device composed of a pair of left and right small cameras, a controller for controlling the position of the camera device, and images captured by the camera device. It is configured by a monitor device or the like that displays separately.

  The monitor device is provided with a small monitor for displaying images of a pair of left and right small cameras, and an eye cup having a lens inside thereof, whereby an image captured by the camera device is enlarged and displayed. It can be stereoscopically viewed.

  Furthermore, since the camera device can be moved in the vertical and horizontal directions by the controller, the observer can easily observe the image in the desired direction by controlling the position of the camera device by the controller. Is.

  On the other hand, in recent years, various so-called computer games and the like that display moving images on a display device (hereinafter referred to as a display or the like) such as a television or a personal computer (PC) have been put into practical use.

  These games have various contents. For example, as shown in FIG. 45, the display screen scrolls in the vertical direction (arrow Y direction shown in FIG. 45) to shoot down enemy fighters. As shown in FIG. 46, the display screen scrolls in the horizontal direction (arrow X direction shown in FIG. 46) and the game progresses by defeating enemy characters. There are various things.

  Therefore, the conditions such as the size of the screen frame and the aspect ratio (aspect ratio) of the screen that are most enjoyable for each game, etc. and that are more comfortable and more realistic are different for each game. Is.

  Also, in games where speed is important, even if the CPU processing is set to speed priority and the image quality of the display image is set to low accuracy, it can be fully enjoyed, but the display image progresses at a low speed. In a game whose content emphasizes display content such as game characters (narrative) and moving images themselves, it is more enjoyable to set the display image to a high-definition image. It becomes.

  Therefore, when creating various game software, the display, etc. for confirming the video image has the same screen frame size, aspect ratio (aspect ratio), image quality, etc. as the display for actually playing the game. It is desirable to use the one corresponding to.

  However, in the present situation, in the case of a home game that is personally enjoyed at a general home, it is common to use a home TV as its display, etc., so depending on the contents of various games, It is not produced in consideration of setting and changing an appropriate screen frame size, aspect ratio, image quality, and the like.

  In addition, in order to be able to enjoy any kind of game, it is necessary to prepare a display with a high definition image quality and a large screen frame. In this case, Since a dedicated display is prepared and the display is very expensive, a large space is required for its installation, which is not practical. Such a problem is not limited to use at home, but is a similar problem in, for example, an amusement park, game center, game software development site, and the like.

  Therefore, in recent years, a head-mounted image display device such as a so-called head-mounted display, which is mounted so as to cover the face from the head as a small display for displaying images or for use in various games, etc. Various proposals have been made.

  For example, a game display disclosed in Japanese Patent Laid-Open No. 4-33679 includes a video projector and an optical path changing member arranged to guide video display light emitted from the video projector to a predetermined direction. The image projector includes an optical image display unit having a display surface for displaying an image corresponding to an image signal from the game machine main body, and an optical path change of the image display light emitted from the display surface And an optical member that projects toward the member (mirror).

  According to this, it is possible to immerse yourself in the game world (atmosphere) by blocking unnecessary information in the surroundings, and to maintain the distance between the eye and the display image appropriately, thereby reducing eye fatigue and visual acuity The decrease can be reduced.

Further, the shooting toy disclosed in Japanese Patent Laid-Open No. 5-180595 is composed of a simulated gun, goggles, a cable for transmitting a signal between the simulated gun and goggles, and the like. Makes a hit judgment based on the trigger signal of the simulated gun and the state of the light receiving signal of the infrared light receiving means of the goggles. On the other hand, when the infrared light receiving means of the goggles receives a predetermined infrared signal, it is determined that the shot Thus, information such as hits and bullets is displayed on a part of the glasses of the goggles by the display means.

  However, as described above, when two independent imaging / playback devices are used during the production of stereoscopic video, the two independent imaging devices must be operated at the same time. There is a problem in that time, labor, and the like for creating object data are required.

  Further, in order to capture an image similar to the object image when the observer visually observes, the eye width, that is, the distance between the eyes, and the distance between the two cameras L and R that perform imaging (baseline length: normal length) In this case, it is necessary to arrange the cameras L and R side by side so that the base line length is set to about 50 mm to about 70 mm and an average of about 65 mm. It is necessary to set the installation angle so as to coincide with the convergence angle of the eye when the observer views the object image directly with the naked eye.

  In order to obtain such a good stereoscopic image, the setting items of the imaging conditions related to the arrangement of the cameras L and R at the time of imaging increase, so that the two cameras that perform imaging are independent. In particular, there is a problem that the setting of the imaging conditions becomes complicated.

  When confirming the 3D image being created, the viewfinders of the two cameras L and R arranged independently are observed with the left and right eyes, respectively, as is conventionally done. There is also a problem that it is very difficult to do.

  In addition, in order to check a stereoscopic image with the liquid crystal shutter glasses, a special work of re-recording the L and R images in the field sequentially is necessary, which increases time and costs. There is a problem of being efficient.

  Furthermore, a system for observing (confirming) a stereoscopic video (a system comprising a camera, a video deck, etc., see FIG. 44) is a system different from a device for producing a stereoscopic video, such as a computer. Therefore, when the stereoscopic image created by this computer or the like is to be confirmed, a display device fixed at a different position from the installation position of the computer or the like for performing the creation work, that is, the camera L, It is necessary to move to the R finder section (see FIG. 44), and there is a problem that the working efficiency is lowered.

  In addition, by requiring two image pickup devices, the entire system becomes large, and it becomes difficult to secure a place for installing a system including two image pickup devices. There is a problem that it is difficult to carry and use.

  Further, according to the means disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 7-75134, the configuration becomes large as in the imaging system exemplified in FIG. 43 and the observation system exemplified in FIG. Therefore, there is a problem that it is difficult to carry and use, and it seems that object data cannot be easily created with this apparatus.

  When the left-eye video and the right-eye video are separately created by two computers, and the image creation, image processing, and the like are performed separately, the created pair of left and right videos are captured by the two imaging devices. It is necessary to capture, and it may be a larger system.

  On the other hand, the head-mounted video display device disclosed in the above Japanese Patent Laid-Open No. 4-33679, the above Japanese Patent Laid-Open No. 5-180595, etc. displays information such as an appropriate screen frame according to the contents of various games. It is not displayed but dedicated to one particular game, and in these particular games it can be used in an optimal form, but to be used in other games , There is a possibility that the sense of reality is insufficient or the comfort for playing the game is reduced.

  Such a head-mounted video display device can be easily used as a small display device for playing various games and as a display for checking video images when creating various game software. However, when these head-mounted video display devices are mounted, the surrounding situation cannot be seen, so various settings of the display device itself such as eye width adjustment, diopter adjustment, etc. There is a problem that it is difficult to perform and complicated.

  Further, when the user does not know (does not know) the operation method of the game to be started, an operation manual (hereinafter referred to as a manual or the like) is referred to when the head-mounted image display device is worn. There is also the problem that it cannot be done.

  Also, if an accident such as a power outage occurs during a game, or if you forget the procedure for ending the operation and interrupt the power supply, It is also conceivable that the game is interrupted at that time, and the game progress status and results up to just before the interruption are erased without being stored in the memory or the like.

  The present invention will be described below with reference to the illustrated embodiments.

  Before describing the details of the embodiment of the present invention, two configuration examples of a video observation apparatus, which is a system to which the head-mounted video display apparatus of the present invention is applied, will be described below.

  First, a first configuration example of an image observation apparatus to which the head-mounted image display apparatus of the present invention is applied will be described with reference to FIGS.

  FIG. 1 is a diagram showing an outline of a first configuration example of an image observation apparatus to which the head-mounted image display apparatus of the present invention is applied. Note that the video observation apparatus shown in the first configuration example is an example of a case where a stereoscopic video is produced and a case where it is used to check a stereoscopic video created during the production work.

  That is, this video observation apparatus is a head-mounted video display apparatus 1 which is a video display means adapted to display an image based on a video signal supplied to the observer on both eyes of the observer by a corresponding video display unit. A computer 3 having specifications suitable for producing a video that can be projected by the head-mounted video display device 1 and having an output unit for outputting a video signal representing the video; An arbitrary operation by the operator regarding the mode of supplying video signals from the computer 3 to the head-mounted video display device 1 is inserted in a signal transmission path between the computer 3 and the head-mounted video display device 1. It is comprised by the controller 2 for performing.

  The computer 3 is formed by two sets of computers, a computer 3L that mainly processes a video signal for the left eye among video signals that form a stereoscopic video, and a computer 3R that mainly processes a video signal for the right eye. The computer 3L and the computer 3R are network-linked by a cable 3a. In general, the computer 3L and the computer 3R have substantially the same specifications.

  The computer 3 (L, R) is a computer main body 3d composed of a control circuit formed by a CPU or the like, a display 3e that is a display means for work for displaying a video signal, and an operator arbitrarily operating the computer 3 (L, R). The keyboard 3f is an instruction input means for inputting an instruction command (command) or the like to a control circuit or the like in the computer main body 3d, and a video signal (for example, an S-Video signal, for example) output from the computer main body 3d. A VGA signal or the like is output to the controller 2 via a cable 3b having one end connected to the output unit.

  Here, the video signal output from the output unit of the computer 3 (L, R) is used for the left eye and the right eye by a timing controller which is a synchronization circuit provided in the computer 3 (L, R). Thus, a synchronization relationship of the output timing of the video signal is ensured and output to the controller 2.

  An audio signal output from the computer main body 3d is also output to the controller 2 via a cable 3c having one end connected to the output section of the computer main body 3d. The audio signal only needs to be output from the computer main body 3d of either the computer 3L or the computer 3R. This is because the computer 3L and the computer 3R are network-linked. FIG. 1 illustrates a case where the cable 3c for transmitting an audio signal is connected to the computer 3L.

  The computer 3 (L, R) performs various image processing such as modeling software for producing an original image (basic data), software for editing and producing an original image, rendering software for editing and producing a completed image, and the like. A software group (not shown) is built in, and a large amount of memory (not shown) is secured to perform these image processing, that is, various calculations relating to video information, data processing, and the like. ing.

Note that the rendering software described above is the original image data (basic data) of the object shape produced by the modeling software, for example,
1) Polygon (polygon): Three-dimensional object data represented by triangles using computer graphics (CG), etc.
2) Solid model; one of the three-dimensional representations in computer graphics (CG), which also includes solid data surrounded by three-dimensional surfaces,
It is software that can perform such processing.

  In other words, for example, when rendering original image data of an object shape as a stereoscopic image by rendering software, it is possible to display the object from various viewpoints by converting it into data as a polygon. And free expression according to the position of the object.

  More specifically, as shown in FIG. 3, when creating the shape (image) data of the object 5 to create a stereoscopic image, for example, the two imaging devices (cameras) 4L, 4R arranged side by side Assuming that 5 is imaged, a pair of images obtained by the imaging devices 4L and 4R at this time, that is, image data L for the left eye and image data R for the right eye are created.

  In this case, the rendering software performs the observation position (camera angle or the like) of the virtual cameras 4L and 4R with respect to the object 5, the gazing point (the distance to the object, etc.), and the camera interval (baseline length, symbol D shown in FIG. 3). ), An installation angle of the camera (an angle corresponding to the convergence angle; reference symbol A shown in FIG. 4), and the like can be arbitrarily set.

  As described above, the interval between the virtual cameras 4L and 4R (base line length D) is set to a base line length D of about 50 mm to about 70 mm and an average of about 65 mm as described above. This is an average value of the human eye width, that is, the distance between both eyes. By setting the camera distance in this way, it is possible to obtain image data having a natural shape closer to the naked eye.

  As described above, the rendering software can express various stereoscopic effects using the observation positions and installation angles of the virtual cameras 4L and 4R as parameters.

  FIG. 2 is a schematic perspective view showing an appearance of a head-mounted image display device applied to the image observation device of the first configuration example.

  As shown in FIG. 2, the head-mounted video display device 1 includes a main body 1a containing a video display component, that is, a video display unit and the like, and a frame unit 1b connected to the main body 1a. A forehead pressing portion 1d that is a support portion provided at the front center upper portion of the main body portion 1a, a headband 1c that is a support portion provided on the inner side of the frame portion 1b and in contact with the head, and a frame Temporal support, which is a support portion that is provided with a leaf spring or the like as an elastic member, projecting from the vicinity of the position where the portion 1b is connected to the main body portion 1a toward both side heads on the rear side of both ears It is configured by a portion 1e and a speaker 1f or the like that extends obliquely downward and rearward from the vicinity of the front side of the base end portion of the temporal support portion 1e and is provided at a position facing both ears when worn.

  In the main body 1a, an image display unit composed of an LCD (Liquid Crystal Display) or the like is provided corresponding to each of the eyes of the observer, and this image display unit allows the computer 3 (L, R) to be used. An image based on the video signal output from the output unit and supplied to the head-mounted video display device 1 is displayed via a controller 2 (details will be described later).

  In the video display unit, a pair of video display units for the left eye and the right eye are independently formed, and video signals for the left eye and the right eye are displayed independently on the respective video display units. It has come to be.

  The head-mounted image display device 1 has a so-called see-through function that can selectively switch between the image displayed on the image display unit and the external environment. With this see-through function, only a first operation mode for observing an image based on a video signal supplied to the head-mounted image display device 1 in a state where the external field of view is blocked, and only the external field of view is ensured. The second operation mode and the second operation mode in a state of becoming, and these two operation modes can be selectively applied.

  Then, the liquid crystal shutter (not shown in FIG. 2) in the head-mounted video display device 1 is cut off, or the open / close degree of the liquid crystal shutter is adjusted to change the transparency of the video display unit. This function allows you to selectively see the video and the outside world. Therefore, by enabling this function, other operations can be easily performed even when the head-mounted image display device 1 is worn.

  On the other hand, as described with reference to FIG. 1, the controller 2 is inserted in the signal transmission path between the computer 3 (L, R) and the head-mounted image display device 1, and the computer 3 ( The video signal and the audio signal output from the output unit L, R) are input to the controller 2 via the cables 3b and 3c.

In the controller 2, the manner in which the video signal input from the computer 3 (L, R) is supplied to the head-mounted video display device 1 can be switched by performing an arbitrary operation by the operator. It has become. Here, as a supply mode of the video signal that can be switched to the head-mounted video display device 1, for example,
1) A mode for displaying only the video based on the left-eye video signal on the left-eye and right-eye video display units,
2) A mode for displaying only the video based on the video signal for the right eye on each of the video display units for the left eye and the right eye,
3) a mode for displaying an image based on a video signal for the left eye on the video display unit for the left eye, and an image based on a video signal for the right eye on the video display unit for the right eye;
Such a supply mode (display mode) can be considered.

  In addition, the controller 2 displays the left-eye and right-eye video signals input from the computer 3 on the left-eye and right-eye video display units of the head-mounted video display device 1, respectively. There is provided a signal conversion circuit for converting into the above signal. This signal conversion circuit will be described below with reference to the block diagram of FIG.

  The signal conversion performed by the signal conversion circuit includes, for example, an operation for converting an interlace signal into a non-interlace signal.

  As shown in FIG. 6, left-eye and right-eye video signals (an S-Video signal is illustrated in FIG. 6) input to the controller 2 from the computer 3 (L, R). The signal is separated into an RGB signal and a synchronization signal by a synchronization separation circuit 2m in the signal conversion circuit.

  The RGB signal is converted from an analog signal to a digital signal by the A / D converter 2n, and then stored in the memory unit 2p including a frame memory or the like. On the other hand, the synchronization signal is input to the TG (timing generator) 2t via the PLL (phase lock loop) 2s, and then stored in the memory unit 2p, and also the LCD of the head mounted video display device 1 The drive circuit 1m (L, R) is supplied as an H (horizontal clock) signal and a V (vertical clock) signal.

  The video signal stored in the memory unit 2p is converted from a digital signal to an analog signal by the D / A converter 2r and then output to the LCD drive circuit 1m (L, R).

  That is, the TG 2t controls the timing of writing and reading the input video signal to the memory unit 2p.

  Note that the signal conversion circuit in the controller 2 is provided for each of the left eye and the right eye, and separately processes the video signals for the left eye and the right eye. Therefore, regarding the video signal output from the computer 3 (L, R), the output timing synchronization relationship performed by the timing controller in the computer 3 is ensured to be output to the controller 2 within an allowable value of one frame. For example, it is possible to display a stereoscopic image on the video display unit (LCD) 1n of the head-mounted video display device 1.

  In the video observation apparatus of the first configuration example configured as described above, the reproduction operation for confirming the created stereoscopic video performed during the creation of the stereoscopic video is briefly described below with reference to the flowchart of FIG. Explained.

  As shown in FIG. 5, first, in step S1, video data, for example, a CG image, by a desired video signal created by the operator to the computer 3 via the keyboard 3f of either the computer 3L or 3R. A reproduction command for reproducing data is input (key-in (IN)), and the process proceeds to the next step S2.

  Here, since the computers 3L and 3R are network-linked as described above, when a playback command is input from one keyboard 3f, the other computer 3R (or 3R) is connected via the computer 3L (or 3R). 3L), a reproduction command is transmitted. Therefore, the computer 3L, 3R is in a state where a reproduction command is input simultaneously.

  Next, in step S2, the computer 3 starts the reproduction operation of the video data based on the desired video signal, that is, the reproduction output of the left-eye and right-eye video signals, and proceeds to the next step S3. .

  In the reproduction operation of the video data by the video signal in the above-described step S2, the reproduction output of the video signals for the left eye and the right eye is a timing controller which is a synchronization circuit provided in the computer 3 in step S3. The synchronization relationship of the output timing is ensured (synchronized) by (not shown), and the process proceeds to the next step S4.

  In step S4, video data (CG data) based on the video signal is output as an S-Video signal, for example, from the output unit of the computer 3 to the controller 2, and the process proceeds to the next step S5.

  In step S5, the video signal (S-Video signal) from the computer 3 in step S4 described above is input to the head-mounted video display device 1 via the controller 2, and the head-mounted video display device 1 The LCD drive circuit for driving the video display unit is driven, and the process proceeds to the next step S6.

  In step S6, the LCD drive circuit displays a video image of a desired video signal on the video display unit of the head-mounted video display device 1, and then ends the series of sequences (END).

  As described above, according to the first configuration example, since the video display device that is a display means for displaying video is a head-mounted type, video display on a large screen can be performed with a small-scale system. In addition, the video observation apparatus can be made small and excellent in portability.

  Also, the confirmation work of the created stereoscopic video, which is performed when creating the stereoscopic video, can be easily performed without interrupting the video creation work.

  In addition, since the head-mounted video display device 1 has a see-through function, when performing video creation work, it is possible to easily switch between an external field of view and video display as desired. That is, while the head-mounted video display device 1 is mounted, the head-mounted video display device 1 is switched to the second operation mode to secure an external field of view, and various operations, that is, the keyboard 3f While confirming operation, confirming the image during work on the display 3e, etc., the head-mounted image display device 1 is switched to the first operation mode to block the external field of view and confirm the created stereoscopic image. Etc. can be easily performed immediately. Therefore, it can contribute to the improvement of work efficiency.

  Then, by providing a timing controller which is a synchronization circuit in the computer 3, the left-eye and right-eye video signals output from the output unit of the computer 3 are output while ensuring a synchronization relationship. Therefore, a good display image can be observed.

  In the first configuration example described above, the signal conversion circuit in the controller 2 is configured so that two similar circuits are made independent so that the video signals for the left eye and the right eye are processed separately. However, in order to configure the controller 2 at a lower cost, the timing control circuit (corresponding to PLL and TG in FIG. 6) is configured by a single circuit, and a cheaper field as a memory unit. It is possible to adopt a memory.

  That is, FIG. 7 is a block diagram showing a modification of the signal conversion circuit in the controller in the video observation apparatus of the first configuration example.

  FIG. 7 basically has the same configuration as the signal conversion circuit of the controller 2 described with reference to FIG. Therefore, the same reference numerals are given to the same constituent members, and the description thereof is omitted.

  In this modification, as shown in FIG. 7, the left-eye video signal and the right-eye video signal (in FIG. 7, S-Video signals) input from the computer 3 (L, R) to the controller 2 are illustrated. .) Is input to the sync separation circuit 2m in the signal conversion circuit. In the synchronization separation circuit 2m, at least one of the left-eye video signal and the right-eye video signal (the left-eye video signal is illustrated in FIG. 7) is separated into an RGB signal and a synchronization signal. Among the signals, the RGB signal is converted from an analog signal to a digital signal by the A / D converter 2n, and then stored in the memory unit 2p constituting a part of the circuit for the left eye including a field memory. On the other hand, the synchronization signal is stored in the memory unit 2p constituting both the left-eye circuit and the right-eye circuit via the timing control circuit 2t.

  The other video signal (the right-eye video signal is illustrated in FIG. 7) is output to the A / D converter 2n via the synchronization separation circuit 2m, and is converted from the analog signal by the A / D converter 2n. After being converted into a digital signal, it is stored in the memory unit 2p that constitutes a part of the circuit for the right eye.

  The synchronization signal of the timing control circuit 2t is supplied to the TG (timing generator) 1p in the head-mounted video display device 1 connected by connecting means such as a flexible printed circuit board, and the H (horizontal clock) signal and V (Vertical clock) supplied as a signal.

  Next, the respective RGB signals stored in both the left-eye and right-eye memory units 2p are read out by the synchronization signal of the timing control circuit 2t, respectively, and the left-eye and right-eye D / A Each is output to the converter 2r. Each RGB signal is converted from a digital signal to an analog signal by the D / A converter 2r, and then connected to the LCD drive circuit in the head-mounted image display device 1 connected by a flexible printed circuit board (FIG. 7). In FIG. 6, the signals are output to the RGB driver 1 m (L, R).

  On the other hand, a synchronization signal is output from the TG 1p to each of the RGB drivers 1m (L, R) of the LCD drive circuit. By this synchronization signal, each of the RGB drivers 1m (L, R) converts the RGB signals. It is output to the left-eye and right-eye video display units (LCD) 1n while ensuring a synchronous relationship, thereby enabling display as a stereoscopic video.

  When the signal conversion circuit according to the above-described modification is employed, the left-eye and right-eye video signals input from the computer 3 (L, R) to the controller 2 are synchronized in field units. It needs to be taken.

  That is, when synchronization is not achieved in the field unit, it is displayed on the left-eye video display unit 1n (L) and the right-eye video display unit 1n (R) of the head-mounted video display device 1, respectively. As shown in FIG. 8, for example, the video displayed for the left eye (display on the LCD 1n (L)) and the video displayed for the right eye (LCD 1n (R ) Display) is shifted. As a result, it cannot be fused as a stereoscopic image, and the stereoscopic image cannot be recognized.

  As described above, according to the modification of the first configuration example, by adopting such a configuration, it is possible to obtain the same effect as the first configuration example described above, and to make the controller 2 more inexpensive. It can be easily configured.

  In addition, a timing generator is provided in the head-mounted image display device 1, thereby ensuring a synchronization relationship between the left-eye and right-eye image signals and displaying the corresponding image on the image display unit. Therefore, a good display image can be observed.

  Next, a second configuration example of the video observation apparatus to which the head-mounted video display apparatus of the present invention is applied will be described below with reference to FIGS.

  FIG. 9 is a diagram showing an outline of a second configuration example of an image observation apparatus to which the head-mounted image display apparatus of the present invention is applied. The video observation apparatus of the second configuration example, like the video observation apparatus of the first configuration example described above, confirms the created stereoscopic video when producing a stereoscopic video and during the production work. It is an example in the case of using for performing.

  That is, this video observation apparatus, like the first configuration example described above, displays a video based on the video signal supplied to itself on the viewer's eyes by the corresponding video display units. A wearable video display device 1A and a specification adapted to produce a video that can be projected by the head-mounted video display device 1A, and having an output unit for outputting a video signal representing the video And a video signal supply mode from the computer 3A to the head-mounted video display device 1A, which is inserted into a signal transmission path between the computer 3A and the computer 3A and the head-mounted video display device 1A. The controller 2A and the like for performing an arbitrary operation by the operator are configured.

  The computer 3A is composed of a control circuit formed by a CPU or the like, and a computer main body 3A (L) that mainly processes a video signal for the left eye among video signals that form a three-dimensional image. The computer main body 3A (R), which is composed of a control circuit and the like and mainly processes the video signal for the right eye, has two computer main bodies having substantially the same specifications, and the two computer main bodies 3A (L, R). The keyboard 6 is an instruction input means that is connected and inputs an instruction command (command) or the like to a control circuit or the like in the computer main body 3A (L, R) by an arbitrary operation by an operator.

  The two computer bodies 3A (L, R) are electrically connected to the keyboard 6 by cables 3g, respectively, and a controller 2A (details will be described later; see FIG. 10) are electrically connected. A changeover switch 6a that operates in conjunction with the operation of the display changeover switch 2Aa (see also FIG. 10), which is the first switch of the controller 2A, is provided in the keyboard 6.

  That is, in the first configuration example described above, each computer main body 3d has an independent keyboard 3f. In the second configuration example, the two computer main bodies 3A ( L, R) can be selectively switched for operation.

  A video signal (for example, an S-Video signal, a VGA signal, etc.) output from the computer main body 3A (L, R) is output to the controller 2A via a cable 3b having one end connected to the output unit. It has come to be.

  Similarly to the first configuration example described above, the computer 3A (L, R) incorporates software for performing various types of image processing, such as modeling software, image editing software, rendering software, and the like. In order to perform these image processes, that is, various calculations relating to image information, data processing, etc., a large amount of memory (not shown) is secured.

  The other specifications of the computer 3A (L, R) are basically the same as those of the computer 3 (L, R) in the first configuration example described above, and detailed description thereof is omitted.

  On the other hand, the two computers 3A (L, R) and the keyboard 6 are connected to the controller 2A as described above, and the head-mounted video display device 1A is connected.

  The head-mounted video display device 1A is basically the same as that of the first configuration example described above, but the main body of the head-mounted video display device 1A of the second configuration example. As shown in FIG. 9, the display changeover switch 2Aa that is the first switch of the controller 2A and the external image changeover switch 2Ab that is the second switch (details will be described later). ) Having the same function as that in FIG. 3, thereby changing the display mode of the video displayed on the video display unit of the head-mounted video display device 1 A, see-through function, etc. It is possible to switch the display mode between the video and the external image.

  In this second configuration example, the display as the work display device which is the display means in the first configuration example described above is eliminated, and only the head-mounted video display device 1A is replaced with the work display device (monitor). ), And a display device (monitor) for confirming the created stereoscopic video.

  FIG. 10 is a schematic perspective view showing the appearance of a controller applied to the video observation apparatus of the second configuration example, and shows a case when viewed from the front operation panel side.

  As shown in FIG. 10, on the operation panel surface on the front side of the controller 2A, a switching circuit for switching the display mode of the video displayed on the video display unit of the head-mounted video display device 1A is provided at one end thereof. A display changeover switch 2Aa, which is an operation unit of the head, and an external image changeover switch 2Ab for switching the see-through function and the like of the head-mounted image display device 1A are provided.

  Further, the other end of the controller 2A on the operation panel surface is output from the output unit of the computer 3A (L, R) and input to the controller 2A, via which the head-mounted image display device 1A is provided. A volume control dial (hereinafter referred to as a VOL. Dial) 2Ad for controlling the volume of an audio signal output from a speaker (see FIG. 2, reference numeral 1f) is provided.

  Then, on the operation panel surface of the controller 2A, the display changeover switch 2Aa, the external image changeover switch 2Ab, and the VOL. On the surface located between the dials 2Ad, the state of each of these switches is displayed in conjunction with the switching operation of the display changeover switch 2Aa and the external image changeover switch 2Ab, for example, an LED (light emitting diode) or the like. A status display unit 2Ac is provided.

The display changeover switch 2Aa is a switch for changing the display mode of the video displayed on the video display unit of the head-mounted video display device 1A as described above.
1) “L MONITOR”: a first that displays a video signal for the left eye supplied from the computer 3A (L) on the left and right eyes of the head-mounted video display device 1A by the corresponding video display units (LCD). Display mode,
2) “R MONITOR”: a second display in which the right-eye video signal supplied from the computer 3A (R) is displayed on the left and right eyes of the head-mounted video display device 1A by the corresponding video display units (LCD). Display mode,
3) “L / R MONITOR”: The left eye video signal and the right eye video signal supplied from the computer 3A (L, R) are used for the corresponding left eye and right eye of the head-mounted video display device 1A. A third display mode for each display by a video display unit (LCD)
Etc. can be sequentially switched, and the LED of the corresponding status display section 2Ac on the operation panel surface is lit in conjunction with this.

Table 1 below shows the display modes when the video is displayed on the display changeover switch 2Aa and the left-eye and right-eye video display units, that is, the first, second and second display modes. The relationship with the display mode of 3 is shown.

  In Table 1, “2D” indicates that the image displayed in the first and second display modes is a flat image, that is, a two-dimensional image. “3D” indicates that the video displayed in the third display mode is a three-dimensional video, that is, a three-dimensional video.

On the other hand, the external image changeover switch 2Ab is a switch for changing the see-through function of the head-mounted image display device 1A as described above, and each time it is pressed, for example, like the display changeover switch 2Aa, for example,
1) “NORMAL”: a first operation mode for observing an image based on an image signal supplied to the head-mounted image display device 1A in a state where an external field of view is blocked,
2) "SEE THROUGH": See-through function, that is, the second operation mode in which only the external field of view is secured,
3) “SUPER IMPOSE”: a superimpose function, that is, a third operation mode in which the video by the video signal supplied to the head-mounted video display device 1A and the external field of view can be viewed in an overlapping manner;
Etc. can be sequentially switched, and the LED of the corresponding status display section 2Ac on the operation panel is lit in conjunction with this mode.

  In the example shown in FIG. 10, the display changeover switch 2Aa is “L MONITOR” and the external image changeover switch 2Ab is “SEE THROUGH”.

  In addition, a sink circuit is built in the controller 2A, thereby ensuring a synchronization relationship between the left-eye video signal and the right-eye video signal supplied from the two computers 3A (L, R). It is like that. This sink circuit will be briefly described below with reference to the block diagram of FIG.

  As shown in FIG. 11, among the video signals for the left eye (in FIG. 11, a composite signal is illustrated), a signal related to video is input to an A / D converter, and the analog signal is output by this A / D converter. After being converted from a signal to a digital signal, it is stored in a memory unit that forms part of a circuit for the left eye, and among the video signals for the left eye, the synchronization signal is a PLL (Phase Lock Loop) Is stored in the memory unit.

  On the other hand, the readout synchronization signal can be switched between the left eye and right eye Gen Lock signals by a switch circuit. As a result, the synchronization relationship of the right-eye video signal can be ensured using the left-eye video signal as a reference signal, and a so-called Gen Lock circuit is configured.

  In the image observation apparatus of the second configuration example configured as described above, a case where image reproduction is performed for confirmation of the created stereoscopic video, which is performed at the time of creating the stereoscopic video, is shown in FIGS. This will be briefly described below. Here, a case where rendering is performed on the video signal for the left eye by the computer 3A (L) is illustrated.

  First, the video display mode switching sequence will be described below with reference to FIG. As shown in FIG. 13, first, in step S21, it is confirmed whether or not the display changeover switch 2Aa of the controller 2A has been operated (is in an ON state). That is, when the operator operates the display changeover switch 2Aa, the display mode of the video to be displayed on the video display unit of the head mounted video display device 1A is selected, and the display changeover switch 2Aa is turned on. If it is determined that the display mode is selected, the process proceeds to the next step S22.

  In step S22, the controller 2A turns on the LED corresponding to the selected display mode in the status display section 2Ac on the operation panel surface. Here, since it is an example in the case of rendering the video signal for the left eye, the operator turns on the LED of the status display unit 2Ac corresponding to “L MONITOR” by pressing the display changeover switch 2Aa of the controller 2A. It will be. As a result, an image based on the left-eye video signal can be displayed simultaneously on both the left-eye and right-eye video display units (LCD) of the head-mounted video display device 1A. Then, the process proceeds to the next step S23.

  In step S23, the changeover switch 6a of the keyboard 6 is switched so as to correspond to the display mode selected in step S21 in conjunction with the operation of the display changeover switch 2Aa of the controller 2A in step S22. . Here, the changeover switch 6a of the keyboard 6 can be operated as a keyboard for the computer 3A (L). Then, the process proceeds to the next step S24, that is, the video reproduction / display sequence shown in FIG.

  That is, as shown in FIG. 12, first, in step 11, the operator uses the keyboard 6 to play back the video data based on the video signal, for example, CG image data, to the computer 3 </ b> A (L). Is entered (key-in (IN)), and the process proceeds to the next step S12.

  Next, in step S12, the computer 3A (L) starts the reproduction operation of the video data for the left eye using a desired video signal, and proceeds to the next step S13. In step S13, the computer for the left eye Video data is output, and in the next step S14, the left-eye video data is converted from a digital signal to an analog signal by a D / A converter in the computer 3A (L), and then the computer 3A. (L) is output from the output unit to the controller 2A, and the process proceeds to the next step S15.

  In step S15, the left-eye video data input to the controller 2A from the output unit of the computer 3A (L) in step S14 described above is synchronized with the sync generator circuit in the controller 2A. This is output to the wearable video display apparatus 1A, and the process proceeds to the next step S16.

  In step S16, the LCD driving circuit for driving the video display unit of the head-mounted video display device 1A is driven, and the process proceeds to the next step S17. In this step S17, the LCD driving circuit displays the head-mounted video display. The video by the left-eye video signal is simultaneously displayed on both the left-eye and right-eye video display units (LCD) of the apparatus 1A, and the series of sequences ends (RETURN).

  Note that the images displayed on the left-eye and right-eye image display units (LCD) of the head-mounted image display device 1A are both images based on the left-eye image signal. In step S15 described above, Since the synchronization relationship is secured by the sync generator circuit in the controller 2A, it is not difficult to observe the image due to flickering of the screen and the like, and the observer can obtain a planar image (two images) with both the left and right eyes. (Dimensional image) will be observed.

  As described above, according to the second configuration example, only the head-mounted image display device 1A is used as the display unit of the computer 3A (L, R). It is possible to reduce the size, and it is possible to easily perform video creation work and confirm the created video.

  Further, by switching the display changeover switch 2Aa of the controller 2A, the display mode of the video signal to be displayed on the video display unit of the head-mounted video display device 1A can be easily selected. While the apparatus 1A is still mounted, each display mode can be arbitrarily switched and observed. Therefore, it can contribute to the improvement of work efficiency.

  Since the changeover switch 6a of the keyboard 6 is simultaneously switched in conjunction with the changeover operation of the display changeover switch 2Aa, the display mode of the head-mounted image display device 1A and the state of the keyboard 6 are made to correspond to each other. In this case, it is possible to prevent an erroneous operation caused when the two keyboards are used due to a keyboard misplacement or the like.

  Since the two computer main bodies 3A (L, R) are selectively switched and used by the single keyboard 6, the keyboard 6 as the instruction input means is used as the two computer main bodies 3A (L, R, R). R), and thus can contribute to simplification of the configuration of the entire apparatus and reduction of manufacturing costs.

  As in the first configuration example described above, independent keyboards may be provided for the two computer bodies. In this case, two computer main bodies 3A (L, R) need to be network-linked, and a keyboard is also required for each computer main body. On the other hand, each keyboard has a display changeover switch 2Aa of the controller 2A. There is no need to provide a changeover switch 6a that operates in conjunction with the operation, and an interlocking circuit with the controller 2A, an electric circuit for displaying the status of the keyboard 6 itself, and the like can be omitted.

  Next, a first embodiment of the present invention will be described below.

  14 and 15 are diagrams showing an outline of the head-mounted video display device according to the first embodiment of the present invention. FIG. 14 is a conceptual diagram of the head-mounted video display device. FIG. 15 is a block diagram showing the head-mounted image display device in a simplified manner. Note that the head-mounted image display device according to the first embodiment is an example when used for playing a game or the like.

Etc. are constituted.

  Further, on the operation panel surface of the controller 2B, the display changeover switch 2Ba, the external image changeover switch 2Bb, VOL. On the surface located between the dials 2Bd, the status of each switch is displayed in conjunction with the switching operation of the display changeover switch 2Ba and the external image changeover switch 2Bb, for example, an LED (light emitting diode). Part 2Bc is provided.

The display changeover switch 2Ba is a switch for changing the display mode of the video displayed on the video display unit of the head-mounted video display device 1A as described above.
1) “2D”: a display mode in which a two-dimensional video signal supplied from the game card 8 is displayed on the left and right eyes of the head-mounted video display device 1B by the corresponding video display units (LCD),
2) “3D”: Left-eye and right-eye video display units (LCD) corresponding to the left and right eyes of the head-mounted video display device 1B using video data having binocular parallax supplied from the game card 8 ) To display each
At least two modes such as the above can be sequentially switched, and the LED of the corresponding status display section 2Bc on the operation panel surface of the controller 2B is lit in conjunction with this.

  The external image changeover switch 2Bb is a switch for changing the see-through function and the like of the head-mounted image display device 1B, and has exactly the same function as the external image changeover switch 2Ab in the second configuration example described above. It is.

  In the example shown in FIG. 14, the display changeover switch 2Ba is “2D” and the external image changeover switch 2Bb is in “SEE THROUGH”.

  On the other hand, a game card 8 which is a storage medium storing video data having binocular parallax is selectively detachably disposed in the controller 2B, and the head-mounted video display device 1B and the operation are operated. A control pad 7 is connected for performing an operation by the user.

  The head-mounted image display device 1B is basically the same as that of the second configuration example described above. That is, the change-over switches 1Ba and 1Bb provided near the heads on both sides of the main body of the head-mounted image display device 1B according to the first embodiment are the display change-over switch 2Ba and the external image change-over switch of the controller 2B. It has the same function as 2Bb, thereby switching the display mode of the video displayed on the video display unit of the head-mounted video display device 1B, and between the video and the external image such as the see-through function. Switching can be performed.

  Then, as shown in FIG. 15, the controller 2B sequentially reads out video data stored in the game circuit 8 and a control circuit (computer) comprising a CPU and the like for controlling the entire video observation apparatus. A video controller unit (IC) for converting to a video signal, a video display unit (LCD) which is a display element of the head-mounted video display device 1B, and an LCD driving circuit for displaying video based on video signals, and a head-mounted type A speaker control circuit for controlling the volume of the speaker of the video display device 1B, a power source (not shown in FIG. 15), and the like are incorporated.

  The game card 8 is provided with storage means 8a comprising a memory such as a ROM. The storage means 8a has video data having binocular parallax, that is, video data L comprising a left-eye video signal. , And video data R composed of right-eye video signals are respectively stored continuously.

  When the display mode is set to the “3D” mode by the display changeover switch 2Ba or the changeover switch 1Ba of the controller 2B, the addresses of the video data for the left eye and the right eye are alternately read by the field sequential method. The three-dimensional video is displayed on the video display unit of the head-mounted video display device 1B.

  That is, as shown in FIG. 16, for example, the left-eye video signal L1 (1 field; odd field) is first read from the storage means 8a (see FIG. 15) of the game card 8 by the video controller unit. After being output and displayed on the video display unit, the right-eye video signal R1 (1 field; even field) corresponding to the left-eye video signal L1 is read and output to the right-eye video display unit. Is displayed.

  As a result, of the first frame video signal, the left-eye video signal L1 is displayed on the left-eye video display unit, and the right-eye video signal R1 is displayed on the right-eye video display unit. Thus, a display of one frame is formed. In this case, while the video signal R1 for the right eye is read and displayed (Read), the display state of the video signal L1 for the left eye is held (HOLD). While the left-eye video signal L2 (one field) in the video signal for one frame is read and displayed, the right-eye video signal R1 in the previous one-frame video signal. The display state of (1 field) is held (HOLD) (see the hatched portion in FIG. 16).

  Therefore, the corresponding video signals are displayed on the video display units corresponding to the eyes of the observer for the time corresponding to one frame (about 1/30 sec.).

  Then, the video signals L and R are alternately output in the field sequentially to each photographing display unit corresponding to both eyes, and thereby, the stereoscopic video by the head-mounted video display device 1B is output. Observation can be performed.

  As described above, according to the first embodiment, when the game card 8 storing video data having binocular parallax is loaded in the controller 2B, the display changeover switch 2Ba of the controller 2B, or By switching to the “3D” mode with the change-over switch 1Ba of the head-mounted image display device 1B, the display mode can be easily switched, and a game with a stereoscopic image can be enjoyed with a simpler device. Can do.

  Further, since the head-mounted image display device 1B is applied as the image display means, the entire device can be reduced in size, and the changeover switch of the controller 2B or the head-mounted image display device 1B, that is, the external image changeover switch 2Bb. Alternatively, the external image can be blocked (first operation mode) by arbitrarily operating 1Bb. Therefore, it is possible to enjoy a game with a more powerful feeling and presence.

  Then, by selectively inserting / removing various game cards 8 storing video data having different contents with respect to the controller 2B, various desired games can be easily enjoyed.

  It should be noted that even when the video supplied by the computer is displayed in a field sequential manner, the same configuration as that of the head-mounted video display device 1B can be used. In this case, a CRT controller is used.

  Next, a second embodiment of the present invention will be described below.

  17 and 18 are diagrams showing an outline of the head-mounted image display device according to the second embodiment of the present invention. FIG. 17 is a conceptual diagram of the head-mounted image display device. FIG. 18 is a block diagram showing the head-mounted image display device in a simplified manner. The head-mounted image display device according to the second embodiment is an example when used for playing a game or the like, similar to the first embodiment described above, and the aspect ratio of the screen ( It is an example of a head-mounted image display device that can change the aspect ratio.

  As shown in FIG. 17, this head-mounted image display apparatus is a head-mounted image display device configured to display an image based on a video signal supplied to itself on the viewer's eyes by the corresponding image display units. The video card 1C and the game card 8C, which is a storage medium storing auxiliary information defining video data and video display mode (video mode), can be selectively loaded, and the loaded game card The video data read from 8C is operated by the control pad 7C, which is an operation means for performing an arbitrary operation by the operator, and the video signal corresponding to the video data subjected to the operation is converted into a head-mounted type. The controller 2C is supplied to the video display device 1C.

  A game card 8C is selectively detachably attached to the controller 2C, and a head-mounted image display device 1C and a control pad 7 are connected to the controller 2C. In the second embodiment, the same control pad 7 as that in the first embodiment is applied.

  On the operation panel surface on the front side of the controller 2C, a main power switch (POWER SW) 2Ca for turning on / off the main power and a game card 8C loaded in the controller 2C are initialized. A reset switch (RESET SW) 2Cb is provided.

  As shown in FIG. 18, in the controller 2C, a control circuit including a CPU and the like for controlling the operation of the entire video observation apparatus, a game card attachment detection circuit for detecting the attachment state of the game card 8C, and an attachment Auxiliary information defining the video display mode (video mode) and the like is read from the game card 8C, and the display mode (video mode) in the video display unit of the head-mounted video display device 1C is relied on this auxiliary information. A video mode control circuit to be controlled and a display unit drive circuit that is controlled by the video mode control circuit and drives the display unit in the head-mounted video display device 1C to switch the arrangement of the display units are incorporated. ing.

  The game card 8C is provided with storage means 8Ca composed of a memory such as a ROM. In the storage means 8Ca, as described above, auxiliary information for defining a video display mode (video mode) and the like. 8Cc, video data 8Cb for forming video, and the like are stored.

  Specifically, the auxiliary information 8Cc includes, for example, information indicating the aspect ratio of the display screen that allows the video data of the game card 8C to be observed in an optimum state.

  The head-mounted image display device 1C is basically the same as that in the first configuration example described above, but the head-mounted image display device 1C in the second embodiment is applied. The configuration of the display unit constituting the video display unit of the type video display device 1C is different.

  That is, FIG. 19 shows one of the left-eye and right-eye image display units corresponding to the eyes of the observer of the head-mounted image display device in the image observation device of the second embodiment. It is a principal part expansion perspective view which takes out only this display unit and shows it simply. Here, only one of the display units constituting the left-eye and right-eye video display units is shown and the other is omitted, but the video display unit of the head-mounted video display device 1C is Two similar structural units are configured as a pair.

  As shown in FIG. 19, the display unit 9 is formed by a liquid crystal panel (LCD), a backlight, or the like, and forms a video display unit 9e that displays a video based on a video signal, and a video displayed by the video display unit 9e. The image display unit 9e and the optical system 9a are formed integrally with each other. A flexible printed board 9d is connected to the video display unit 9e, and a video signal is supplied to the video display unit 9e from the controller 2C via the flexible printed board 9d.

  The display unit 9 is provided with a display unit rotating shaft 9b for rotating the entire display unit 9, and a pinion gear 9c is fixed to the display unit rotating shaft 9b. A reduction gear 10a meshes with the pinion gear 9c, and the reduction gear 10a is fixed to a rotating shaft of a motor 10 that is a driving means and can rotate forward and backward.

  Accordingly, the rotational driving force of the motor 10 is transmitted to the display unit rotating shaft 9b via the reduction gear 10a and the pinion gear 9c, whereby the display unit 9 is rotated.

  Note that the head-mounted image display device 1C in the second embodiment is different from the head-mounted image display device in the first and second configuration examples and the first embodiment described above, There is no changeover switch for the external image such as a see-through function, and therefore, the head-mounted image display device with a general type that is always in a shielded state with respect to the external field, that is, a so-called negative type liquid crystal shutter. Has been applied.

  The operation of the image observation apparatus of the second embodiment configured as described above will be briefly described below.

  First, an arbitrary game card 8C is loaded into the controller 2C in which the main power switch 2Ca is turned on. Then, the game card mounting detection circuit in the controller 2C detects that the game card 8C is mounted, and information to that effect is transmitted to the CPU in the controller 2C.

  In response to this, the CPU in the controller 2C issues an information read instruction to the video mode control circuit. As a result, the video mode control circuit reads out the information related to the video mode stored in the storage means 8Ca of the attached game card 8C, that is, the auxiliary information 8Cc that defines the display mode of the video and the like. The display unit drive circuit is controlled based on the supplementary information 8Cc, and the arrangement of the display unit 9 is switched accordingly.

  In other words, the video mode control circuit reads information representing the aspect ratio of the screen from the storage means 8Ca of the game card 8C as auxiliary information 8Cc that defines the display mode and the like of the read video, and stores the information in the auxiliary information 8Cc. Based on this, the arrangement of the display unit 9 is switched.

  Here, for example, when the information indicating the aspect ratio of the screen is “horizontal screen” as the auxiliary information 8Cc, the display unit drive circuit is controlled as shown in FIG. As a result, the motor 10 (not shown in FIG. 20; see FIG. 19) is rotationally driven to rotate the display unit rotating shaft 9b in the direction of arrow A shown in FIG. Thereby, the display unit 9 rotates in the same direction as a whole, and becomes a state shown in FIG. Accordingly, the observer's eye 20 can observe the “horizontal” screen frame.

  When another type of game (a game of a different game card 8C) is to be started, the game card 8C that is already mounted (used this time) is removed from the controller 2C, and the other (used next) After the game card 8C is loaded into the controller 2C, the controller 2C is initialized without turning off the main power switch 2Ca by pressing the reset switch 2Cb. Thereby, the controller 2C again detects the mounting state of the game card 8C by the game card mounting detection circuit, and then reads the auxiliary information regarding the video mode stored in the storage means 8Ca of the newly mounted game card 8C. Thus, the same operation is performed based on the read auxiliary information.

  As described above, according to the second embodiment, the storage unit 8Ca in the game card 8C stores auxiliary information 8Cc (for example, the aspect ratio of the display screen) that prescribes the video display mode (video mode) and the like. And the like, and when it is detected that the game card 8C is mounted on the controller 2C, the auxiliary information 8Cc related to the video mode is read, and based on the read auxiliary information 8Cc, Since the aspect ratio of the display screen is controlled by rotating the display unit constituting the video display unit, observation is performed in an optimum state for the video of the attached game card 8C, that is, the optimum aspect ratio of the screen. be able to. Therefore, it is possible to enjoy a more comfortable and more realistic game.

  By applying the head-mounted image display device 1C as the image display means, the entire device can be reduced in size.

  In the second embodiment described above, control is performed such that the entire display unit is rotated. However, the present invention is not limited to this. For example, it may be configured to rotate only the video display unit.

  That is, FIG. 21 is a diagram showing a modification of the second embodiment, and one display unit constituting the left-eye and right-eye video display units of the head-mounted video display device. It is a principal part expansion perspective view which takes out only and shows easily.

  In FIG. 21 as well, as shown in FIG. 19, the video display unit of the head-mounted video display device is configured by a pair of two similar constituent units. Only one of the display units constituting the video display unit for the eye and the right eye is shown, and the other is omitted.

  In addition, the display unit of this modification example has basically the same configuration as the display unit 9 (see FIG. 19) of the second embodiment described above, and therefore the same components are the same. Reference numerals are assigned and explanations thereof are omitted.

  As shown in FIG. 21, a display unit 9A of this modification is formed by a liquid crystal panel (LCD), a backlight, and the like, and an LCD unit 9Ae that is a video display unit that displays video based on a video signal, and the LCD unit 9Ae The optical system unit 9Aa guides the luminous flux forming the image displayed by the image to the observer's eye.

  The optical system unit 9Aa is fixed in the head-mounted image display device, and the LCD unit 9Ae is disposed so as to be rotatable with respect to the optical system unit 9Aa. That is, the LCD unit 9Ae is provided with an LCD unit rotation shaft 9Ab for rotating the LCD unit 9Ae with respect to the optical system unit 9Aa, and a pinion gear 9c is fixed to the LCD unit rotation shaft 9Ab. It is installed. A reduction gear 10a meshes with the pinion gear 9c, and the reduction gear 10a is fixed to a rotating shaft of a motor 10 that is a driving means and can rotate forward and backward.

  Accordingly, the rotational driving force of the motor 10 is transmitted to the LCD unit rotating shaft 9Ab via the reduction gear 10a and the pinion gear 9c, whereby the LCD unit 9Ae rotates.

  FIG. 22 is an essential part enlarged perspective view showing only the LCD unit 9Ae constituting the display unit 9A of this modification.

  As shown in FIG. 22, the LCD unit 9Ae includes a backlight base 11b, a backlight 11a provided on the backlight base 11b, a liquid crystal panel 12b, and a liquid crystal provided on the liquid crystal panel 12b. The display unit 12a includes a flexible printed circuit board 13 that electrically connects the backlight substrate 11b and the liquid crystal panel 12b.

  The irradiation surface of the backlight 11a is arranged toward the optical system unit 9Aa (not shown in FIG. 22, see FIG. 21), and the irradiation light from the backlight 11a is emitted from the back side of the liquid crystal display unit 12a. After being incident and transmitted through the liquid crystal display unit 12a, the light is guided into the optical system unit 9Aa.

  FIG. 23 is a diagram when the LCD unit 9Ae and the optical system unit 9Aa are viewed from the side, and the irradiation light irradiated by the backlight 11a and the image displayed on the liquid crystal display unit 12a are the eyes of the observer. It is a conceptual diagram which shows the optical path until it reaches | attains 20. FIG.

  As shown in FIG. 23, the optical system unit 9Aa includes a half mirror 15 made of a semi-transmissive mirror, a concave mirror 14 and the like, and a backlight that constitutes the LCD unit 9Ae on the upper surface side of the optical system unit 9Aa. 11a and a liquid crystal display unit 12a are provided. The half mirror 15 is disposed at an angle of about 45 degrees with respect to the light emitted from the backlight 11a.

  In the modified example configured as described above, the irradiation light of the backlight 11a passes through the liquid crystal display unit 12a and is irradiated downward from the upper surface side of the optical system unit 9Aa. Thereby, the image | video displayed on the liquid crystal display part 12a will be illuminated by the irradiation light of the backlight 11a.

  Then, the irradiation light of the backlight 11a passes through the half mirror 15, enters the concave mirror 14, is collected by the concave mirror 14, is reflected by the inclined surface on the lower surface side of the half mirror 15, and bends its optical path. And enters the observer's eye 20. As a result, the observer's eye 20 can observe the image displayed on the liquid crystal display unit 12a.

  The operation of the video observation apparatus according to the modified example configured as described above is substantially the same as that of the above-described second embodiment.

  That is, the video mode control circuit (see FIG. 18) reads out information relating to the video mode stored in the storage means of the attached game card, that is, auxiliary information defining the video display mode and the like. Based on the output auxiliary information, the display unit driving circuit is controlled to switch the arrangement of the LCD unit 9Ae.

  In other words, the video mode control circuit controls the display unit drive circuit as shown in FIG. 21 as auxiliary information for defining the display mode of the read video, for example, by information indicating the aspect ratio of the screen, and controls the motor. Is rotated to rotate the LCD unit rotating shaft 9Ab in the direction of arrow B shown in FIG. As a result, only the LCD unit 9Ae rotates in the same direction, and is in a state indicated by a dotted line in FIG. Therefore, the observer's eye 20 can observe the “vertically long” screen frame.

  As described above, according to the modification of the second embodiment, the same effect as that of the second embodiment can be obtained.

  Further, in this modification, only the LCD unit 9Ae is rotationally driven, so that a smaller driving force is required compared to the case where the display unit 9 in the second embodiment described above is rotationally driven as a whole. Thus, the same effect can be obtained, and since the rotating member is small, less space is required for moving the rotating member, which contributes to downsizing of the apparatus.

  In this modification, all the components for rotating the LCD unit 9Ae can be arranged at positions other than the front side of the display unit 9, so that the liquid crystal shutter of the head-mounted image display device is Similar to the above-described second embodiment, it is better to use a negative type having excellent light shielding characteristics, but it is also possible to use a positive type. In this case, with respect to the controller, the head-mounted image display device, etc., the same configurations as those in the first and second configuration examples and the first embodiment described above, that is, the external image changeover switches 2Bb, 1Bb, etc. It is necessary to provide.

  In the above-described second embodiment and its modifications, the rotation operation of the display unit 9 or the LCD unit 9Ae is performed by a driving member such as the motor 10. However, the present invention is not limited to this. The operation unit may be a manual operation in which an operation member such as a knob is fixed to the rotation axis of the LCD unit and the operation member is manually rotated.

  FIG. 24 is a diagram showing another modification of the second embodiment of the present invention, which is a schematic side view of the head-mounted image display device 1D, and FIG. 25 is a head-mounted image display. It is a principal part expansion perspective view which takes out only one display unit which comprises the image display part for left eyes and right eyes of an apparatus, and shows it simply.

  In FIG. 25 as well, as in FIGS. 19 and 21 described above, the video display unit of the head-mounted video display device is configured by a pair of two similar constituent units. Therefore, only one of the display units constituting the left-eye and right-eye video display units is illustrated, and the other is omitted.

  As shown in FIGS. 24 and 25, in another modification, the display unit 9B disposed in the head-mounted image display device 1D has an operation member 16 such as a knob on the upper surface side. 24, and is rotatably arranged in the direction of arrow C shown in FIG.

  The display unit 9B is formed of a liquid crystal panel (LCD), a backlight, etc., as with the display unit 9A of the above-described modification, and an LCD unit 9Be that is an image display unit that displays an image based on an image signal. The optical system unit 9Ba guides a light beam forming an image displayed by 9Be to an observer's eye as an image.

  The optical system unit 9Ba is fixed in the head-mounted image display device 1D, and the LCD unit 9Be is rotatably arranged with respect to the optical system unit 9Ba. That is, the LCD unit 9Be is provided with an LCD unit rotating shaft 9Bb for rotating the LCD unit 9Be with respect to the optical system unit 9Ba, and the operation member 16 is fixed to the LCD unit rotating shaft 9Bb. It is installed. Further, a projecting member 16a is provided at a substantially central portion of the LCD unit rotation shaft 9Bb in a direction orthogonal to the axial direction of the LCD unit rotation shaft 9Bb.

  Therefore, when the operation member 16 is manually rotated in the direction of the arrow C, the LCD unit rotation shaft 9Bb is rotated. However, stopper members 9Bc and 9Bd project from the upper surface of the LCD unit 9Be. Therefore, the protrusion member 16a comes into contact with the stopper members 9Bc and 9Bd, thereby restricting the rotation of the LCD unit rotating shaft 9Bb.

  That is, the LCD unit 9Bb is allowed to rotate only within the range of 9Bd and the stopper member 9Bc, and the position of the LCD unit 9Be is also restricted by the stopper members 9Bc and 9Bd.

  As described above, according to another modification of the second embodiment, the video data of the attached game card is optimized by rotating the LCD unit 9Be and controlling the aspect ratio of the display screen. Can be observed by the aspect ratio of the display screen that can be observed in a comfortable state, so that a more comfortable and realistic game can be enjoyed.

  Further, since the rotation operation of the LCD unit 9Be can be arbitrarily performed manually, an electric circuit such as a video mode control circuit and a display unit driving circuit (see FIG. 18), a motor, a reduction gear, and the like. Driving members such as columns can be omitted, and an observer (operator) can arbitrarily select an aspect ratio of a desired screen.

  Note that, in this other modified example as well, in the same way as in the above-described modified example, all the structural members for rotationally driving the LCD unit 9Be can be arranged at positions other than the front side of the display unit 9. The liquid crystal shutter of the wearable video display device is preferably a negative type having excellent light shielding characteristics, as in the second embodiment, but can also be a positive type. Also in this case, it is also necessary to provide the external image change-over switches 2Bb, 1Bb and the like for the controller, the head-mounted video display device, and the like.

  Next, a third embodiment of the present invention will be described below.

  FIG. 26 is a conceptual diagram showing a head-mounted image display device according to the third embodiment. Note that the head-mounted image display device of the third embodiment is also used for playing a game and the like, as in the first and second embodiments described above, and is displayed. It is an example of a head-mounted image display device that can change image quality, image magnification, and the like.

  The third embodiment also has basically the same configuration as that of the first and second embodiments described above, so the description of the same components is omitted. Only the different parts are described below.

  As shown in FIG. 26, this head-mounted image display apparatus is a head-mounted image display device configured to display an image based on an image signal supplied to the head on both eyes of an observer by a corresponding image display unit. The video display device 1 and the game card 8 which is a storage medium storing the video data can be selectively loaded, and the video data read from the loaded game card 8 can be arbitrarily operated by the operator. And a controller 2D for supplying a video signal corresponding to the video data subjected to the operation to the head-mounted video display device 1 or the like.

An image quality changeover switch 2Da and the like are provided on the operation panel surface on the front side of the controller 2D, and each time the image quality changeover switch 2Da is pressed, for example,
1) A low resolution (low image quality) mode (see FIG. 29) that displays video with high magnification and low pixel density and prioritizes speed, power, etc.
2) A high resolution (high image quality) mode in which an image is displayed with a low magnification and a high pixel density, and priority is given to the high definition of the image (see FIG. 30),
Etc., at least two display modes can be sequentially switched. In conjunction with this switching operation, the LED of the corresponding status display section (not shown in FIG. 26, see FIG. 10, FIG. 14, etc.) on the operation panel surface of the controller 2D is lit. It is like that.

  In addition, although not shown in FIG. 26, a liquid crystal shutter drive circuit, which will be described later, is provided in the controller 2D and is controlled by a control circuit including a CPU that controls the entire apparatus. .

  27 and 28 are diagrams showing an outline of a display unit constituting the video display unit of the head-mounted video display device 1 according to the third embodiment. FIG. 27 shows the low resolution mode. FIG. 28 shows the state of the display unit in the case of the high resolution mode.

  As shown in FIGS. 27 and 28, the display unit 9 includes an LCD unit including a backlight 11a, a liquid crystal display unit 12a, etc., a half mirror 15, first and second concave mirrors 14A and 14B, and first and second. It is formed by an optical system unit including liquid crystal shutters 17A and 17B.

  The LCD unit is composed of the same members as those in the second embodiment described above, and the description thereof is omitted here. .

  In addition, the optical system unit includes a group of members for guiding a light beam for displaying an image in the low resolution mode as one display mode to the eye 20 of the observer, that is, a half mirror 15 which is a semi-transmissive mirror, The first concave mirror 14A, the first liquid crystal shutter 17A for blocking unnecessary light flux, and the like are arranged on the bottom side of the optical system unit, and for displaying an image in the high resolution mode as the other display mode. A group of components for guiding the light beam to the observer's eye 20, that is, the half mirror 15, the second concave mirror 14B, the second liquid crystal shutter 17B, and the like are on the side facing the position of the eye 20 where the observer observes the display image. Has been placed.

  Note that the head-mounted image display device 1 in the third embodiment does not have a change-over switch for an external image such as a see-through function, as in the second embodiment described above. For the external field of view, a general type that is always in a shielded state, a so-called negative type head-mounted image display device is applied.

  When the display image is observed with the display unit configured as described above, the image quality mode is selected by pressing the image quality changeover switch 2Da of the controller 2D as described above. The operation at this time will be described below with reference to the flowchart of FIG.

  As shown in FIG. 31, first, in step S25, the state of the image quality changeover switch 2Da is confirmed. If the image quality changeover switch 2Da is on, it is determined that the low resolution mode (low image quality mode) has been selected, and the process proceeds to the next step S27. On the other hand, if the image quality changeover switch 2Da is in the OFF state, it is determined that the high resolution mode (high image quality mode) is selected, and the process proceeds to the next step S26.

  In step S25 described above, it is determined that the low resolution mode is selected, and when the process proceeds to step S27, the liquid crystal shutter drive circuit in the controller 2D is driven in step S27, whereby FIG. As shown in FIG. 31, the second liquid crystal shutter 17B is in a shielding state, the incidence of the light beam on the second concave mirror 14B is prevented, and the process proceeds to the next step S28.

  In step S28, a video display operation is performed. That is, in the state of step S27 described above, the image displayed on the liquid crystal display 12a is illuminated by the irradiation light of the backlight 11a, and the light beam forming the image travels below the optical system unit, and is transmitted through the half mirror 15 and the transmission. The light passes through the first liquid crystal shutter 17A in the state and enters the first concave mirror 14A.

  Then, the light beam incident on the first concave mirror 14A is condensed by the first concave mirror 14A and travels again to the half mirror 15 side, is reflected by the inclined surface on the lower surface side of the half mirror 15, and its optical path is bent. It enters the eye 20 of the observer.

  As a result, the observer's eye 20 can observe the image displayed on the liquid crystal display unit 12a. Here, as the display image to be observed, as illustrated in FIG. 29, a video display with a high magnification and a low pixel density (low resolution) is performed in the screen frame. Then, the series of sequences ends (end).

  On the other hand, when it is determined in step S25 that the high resolution mode is selected and the process proceeds to step S26, the liquid crystal shutter in the controller 2D in step S26 is similar to the process in step S27. As shown in FIGS. 28 and 31, the drive circuit is driven, and the first liquid crystal shutter 17 </ b> A enters the shielding state, the incidence of the light beam on the first concave mirror 14 </ b> A is prevented, and the process proceeds to the next step S <b> 28. .

  In step S28, a video display operation is performed. That is, when the image displayed on the liquid crystal display 12a is illuminated by the irradiation light of the backlight 11a in the state of step S26 described above, the light beam that forms the image first travels below the optical system unit, Reflected by the upper-surface-side reflecting surface of the half mirror 15, its optical path is bent, the light travels toward the second liquid crystal shutter 17B in the transmissive state, passes through the second liquid crystal shutter 17B, and enters the second concave mirror 14B. .

  The light beam incident on the second concave mirror 14B is collected by the second concave mirror 14B, travels again to the half mirror 15 side, passes through the half mirror 15 and enters the eye 20 of the observer.

  As a result, the observer's eye 20 can observe the image displayed on the liquid crystal display unit 12a. Here, as an example of the display image to be observed, as shown in FIG. 30, an image display with a low magnification and a high pixel density (high resolution) is performed in the screen frame. Then, the series of sequences ends (end).

  The radius of curvature of the first concave mirror 14A is set to be smaller than the radius of curvature of the second concave mirror 14B. Therefore, the angle θ formed between the optical axis and the optical path when the optical path from the liquid crystal display unit 12a enters the observer's eye 20 is the angle θA in the low resolution mode shown in FIG. Assuming that the angle θB in the case of the high resolution mode shown, the relationship θA> θB is established between the two.

  Here, as the angle θ is larger, a display image with a higher magnification can be obtained, and as the magnification is increased, the number of pixels of the display image in the screen frame having the same area is reduced. That is, a low-resolution video display is obtained.

  In this way, by switching the first and second liquid crystal shutters 17A and 17B and changing the optical path of the display image, the magnification of the image by the same image signal is changed and each display mode (image quality mode) is switched. Will be able to.

  Preferably, the first and second liquid crystal shutters 17A and 17B are provided with a non-reflective coating on the surface on the half mirror side.
