Japanese Patent Laid-Open No. 11-120353 (page 3, FIG. 2)

  However, the above image display device has the following problems. That is, in this image display device, when displaying a list of a plurality of images based on image data, both images based on still image data and images based on moving image data are displayed as still images without movement. The Therefore, for example, when a still image synthesized based on moving image data is an intricate image, whether the synthesized still image is a combination of a plurality of still images, or such a still image ( As a result, it is difficult to determine whether the original image of each image displayed in a list is a moving image or a still image. In this case, for example, a normal still image is displayed on each line in the vertical direction on the display screen, and a plurality of images extracted from the moving image (each representative image) are displayed on the display screen as a normal still image. A method of displaying images side by side in the same size is also conceivable. However, this method has a problem that it is difficult to see because a useless space is generated in the display screen. Further, in the above image display device, since the synthesized still images are not displayed until the processing by the still image conversion unit and the representative image synthesis unit is completed, it is difficult to display a list of each image smoothly.

  The present invention has been made in view of such problems, and when displaying a list of images based on a plurality of image data, it is possible to reliably determine whether the images are still images or moving images. The main object is to provide an obtained image reproduction apparatus and an image reproduction program. Another object of the present invention is to provide an image reproducing apparatus that can realize a smooth list display.

  In order to achieve the above object, the image reproduction apparatus according to the present invention reads a plurality of image data stored in the storage unit and displays each image based on the image data in a plurality of sections of the display unit. An image reproduction apparatus including a control unit that executes display processing, wherein the control unit is configured to extract a plurality of extracted images extracted as still images from the moving image in the plurality of sections when the image is a moving image. In the list display process, a moving display process for displaying the display position while moving the display position in one of them is executed.

  The image reproduction program according to the present invention controls a list display process for reading a plurality of image data stored in the storage unit and displaying each image based on the image data in a plurality of sections of the display unit. When the image is a moving image, the control unit extracts a plurality of extracted images from the moving image as still images, and extracts the extracted images from the plurality of sections. In the list display process, the control unit is caused to execute a moving display process for displaying the display position while moving the display position in one of them.

  In the image reproduction device and the image reproduction program, in the list display process, when the image based on the image data read from the storage unit is a moving image, the control unit is caused to execute the moving display process. For this reason, when the image based on the image data is a moving image, a plurality of extracted images extracted from the moving image can be displayed while moving the display position in one section of the display unit. When displayed, a moving image and a still image can be visually recognized so as to be clearly identifiable. Therefore, according to the image reproduction apparatus and the image reproduction program, it is possible to reliably and easily determine whether each image displayed as a list is a moving image or a still image.

  The image reproduction device according to the present invention is the image reproduction device described above, wherein the control unit is configured to display characters, figures, and symbols indicating that the extraction target image is a moving image when extracting the extracted image. At least one is displayed in one of the plurality of sections.

  In this image reproducing apparatus, at the time of extraction of an extracted image, at least one of a character, a figure, and a symbol indicating that the extraction target image is a moving image is displayed in the section. For this reason, even if it takes a lot of time to extract the extracted image, it is possible to reliably and easily recognize that the extraction target image is a moving image.

  In addition, an image reproduction device according to the present invention includes an extracted image data storage unit that stores extracted image data regarding the extracted image in the image reproduction device described above, and the control unit is a processing target in the moving display process. When the extracted image data to be stored is stored in the extracted image data storage unit, the extracted image data is read and the moving display process is executed.

  In this image reproducing apparatus, when the extracted image data to be processed in the moving display process is stored in the extracted image data storage unit, the control unit reads out the extracted image data and executes the moving display process. For this reason, each extracted image can be displayed in a short time compared with performing the process which extracts an extracted image, and a movement display process simultaneously.

  Also, in the image reproduction device according to the present invention, in the above image reproduction device, the control unit extracts the data name including a character string indicating at least one of generation date and time and data size of image data for the moving image. The extracted image data is stored in the extracted image data storage unit.

  In this image reproducing apparatus, a data name including a character string indicating at least one of the generation date and time and the data size of the original moving image data is given to the extracted image data. For this reason, the extracted image data corresponding to the moving image is extracted by comparing the generation date / time and the data size of the image data of the moving image to be processed in the moving display process with the data name of the extracted image data. Whether or not the data is stored in the data storage unit can be reliably and easily specified.

  The best mode of an image reproducing apparatus according to the present invention will be described below with reference to the accompanying drawings. A rear projection television (hereinafter, also simply referred to as “television”) 1 shown in FIG. 1 is an example of a television in which an image reproduction device according to the present invention is incorporated, and a television broadcast image (for example, a television broadcast image shown in FIG. 2). Gt) can be displayed. The television 1 is configured to be able to display an image (for example, a captured image Gs1 shown in FIG. 3) captured by a digital camera or the like. Specifically, the television 1 includes a main body 2 and a remote controller 3 as shown in FIG. The main unit 2 includes a broadcast receiving unit 11, a switch 12, a video decoder 13, a memory card slot 14, a memory card controller 15, a JPEG / MPEG decoder 16, an image processing unit 17, an extracted image data storage unit 18, and an element driving unit 19. , A display unit 20, a key input processing unit 21, a ROM 22 and a main control unit 23. In this case, the memory card slot 14, the memory card controller 15, the JPEG / MPEG decoder 16, the image processing unit 17, the extracted image data storage unit 18, the ROM 22, and the main control unit 23 constitute an image reproducing apparatus according to the present invention. The television 1 is actually provided with an audio output unit and configured to be able to output various types of audio, but illustration and description thereof are omitted to facilitate understanding of the present invention.

  The broadcast receiving unit 11 receives the television broadcast and outputs the image signal Sb1 of the channel designated by the main control unit 23 to the image processing unit 17. The switch 12 selects one of the image signals input through various signal input terminals such as the composite terminal 41a, the S terminal 41b, the component terminal 41c, and the D terminal 41d under the control of the main control unit 23. Output. The video decoder 13 decodes the image signal output from the switch 12 and outputs it as an image signal Sb2. The memory card slot 14 is configured so that a memory card 4 (see FIG. 2) inserted from an insertion slot 2a (see FIG. 2) formed on the front panel of the television 1 can be connected. In this case, the memory card 4 corresponds to a storage unit in the present invention. As an example, the memory card 4 is a versatile information recording configured to record (store) JPEG still image data, MPEG moving image data, and the like. It is a medium and is used when data is exchanged between various electronic devices (for example, the television 1 and the digital camera). The memory card controller 15 reads the image data recorded on the memory card 4 and outputs it to the JPEG / MPEG decoder 16 under the control of the main control unit 23. The JPEG / MPEG decoder 16 decodes the image data of the JPEG format still image and the MPEG format moving image output from the memory card controller 15 to generate the image signal Sb3 and output it to the image processing unit 17.

  Under the control of the main control unit 23, the image processing unit 17 outputs the image signals Sb1, Sb2, Sb3 (hereinafter referred to as “image signal” when not distinguished from each other) from the broadcast receiving unit 11, the video decoder 13, and the JPEG / MPEG decoder 16, respectively. The display image signal Se for displaying an image on the display unit 20 is generated and output to the element driving unit 19 based on “Sb”. Further, when an image list display (thumbnail display) based on image data recorded (stored) in the memory card 4 is instructed, the image processing unit 17 performs a list display processing 60 described later according to the control of the main control unit 23. Execute. In this case, when the image data recorded on the memory card 4 is moving image data (hereinafter, also referred to as “moving image data”), the image processing unit 17 performs a moving display described later in the list display processing 60. Process 70 is executed. Further, as will be described later, the image processing unit 17 stores the extracted image data generated in the list display processing 60 in the extracted image data storage unit 18. The extracted image data storage unit 18 stores the extracted image data according to the control of the image processing unit 17. The element drive unit 19 generates a drive signal Sd for driving the optical engine 31 (see FIG. 1) of the display unit 20 based on the display image signal Se output from the image processing unit 17.

  As shown in FIG. 1, the display unit 20 includes an optical engine 31 and a screen 32. The optical engine 31 projects the projection light L modulated based on the drive signal Sd output from the element drive unit 19 onto the screen 32. Specifically, the optical engine 31 includes, for example, a light source, a light modulation element (for example, a digital micromirror device or a liquid crystal light valve), and a projection lens (both not shown). The screen 32 receives the projection light L projected from the optical engine 31 and displays an image. The key input processing unit 21 includes a light receiving unit, and receives the infrared signal Si output from the remote controller 3 and photoelectrically converts the infrared signal Si, thereby operating the operation signal So indicating the operation content by the remote control 3. Output to.

  The ROM 22 is composed of, for example, a non-volatile memory, and records a program Pr for operating the main control unit 23 including an image reproduction program according to the present invention. The main control unit 23 constitutes a control unit in the present invention together with the image processing unit 17, and operates according to a program Pr recorded in the ROM 22. In addition, the main control unit 23, in accordance with the operation signal So output from the key input processing unit 21, broadcast reception unit 11, switch 12, video decoder 13, memory card controller 15, JPEG / MPEG decoder 16, image processing unit 17. And the element drive part 19 is controlled.

  The remote controller 3 is formed separately from the main body 2 as shown in FIG. The remote controller 3 is configured by arranging various switches such as a power switch 51, channel switches 52, 52,..., An image signal selector switch 53, a display selector switch 54, and a cursor key 55, and these switches are operated. Sometimes, an infrared signal Si corresponding to each switch and key is output.

  Next, the overall operation of the television 1 will be described with reference to the drawings. In the television 1, when the power switch 51 of the remote controller 3 is operated, the main control unit 23 reads the program Pr from the ROM 22 and operates. Further, power is supplied to the optical engine 31 of the display unit 20 and the light source emits light. Next, the main control unit 23 controls the broadcast receiving unit 11 to cause the image processing unit 17 to output the image signal Sb1 of the channel (for example, channel CH3) that was selected when the power was turned off immediately before. Next, the image processing unit 17 outputs a display image signal Se based on the image signal Sb <b> 1 to the element driving unit 19 under the control of the main control unit 23. Subsequently, the element driving unit 19 outputs a driving signal Sd based on the display image signal Se to the optical engine 31 of the display unit 20 according to the control of the main control unit 23. In response to this, the optical engine 31 modulates the light from the light source into the projection light L based on the drive signal Sd and projects it onto the screen 32. As a result, the television broadcast image Gt of the channel CH3 is displayed on the screen 32 as shown in FIG.

  On the other hand, instead of the television broadcast image Gt, for example, when displaying an image based on an image signal output from an external device such as a VTR and input via the composite terminal 41a, the image signal selector switch 53 of the remote controller 3 is operated. . At this time, the remote controller 3 outputs an infrared signal Si corresponding to the image signal changeover switch 53, and the key input processing unit 21 receives the infrared signal Si and outputs an operation signal So. Next, the main control unit 23 controls the switch 12 according to the operation signal So, and causes the video decoder 13 to output the image signal input via the composite terminal 41a. Subsequently, the video decoder 13 decodes the image signal output from the switch 12 and outputs the image signal Sb2, and the image processing unit 17 outputs the display image signal Se based on the image signal Sb2. Next, the element driving unit 19 outputs a drive signal Sd based on the display image signal Se to the optical engine 31, whereby an image based on the image signal output from the VTR is displayed on the screen 32.

  For example, when the captured image is displayed on the television 1 using the memory card 4 in which the image data of the captured image captured by the digital camera is recorded, the memory card 4 is placed on the front panel as shown in FIG. Is inserted into the memory card slot 14 from the insertion slot 2a. Next, the image signal selector switch 53 of the remote controller 3 is operated. At this time, the main control unit 23 controls the memory card controller 15 according to the operation signal So to read out the image data recorded on the memory card 4 and output it to the JPEG / MPEG decoder 16. In this case, when a plurality of image data is recorded on the memory card 4, the main control unit 23 controls the memory card controller 15 so that, for example, the image data with the latest recording date (shooting date) is read. To do. Subsequently, the JPEG / MPEG decoder 16 decodes the image data and outputs an image signal Sb3. Next, the image processing unit 17 outputs the display image signal Se based on the image signal Sb3, and the element driving unit 19 outputs the drive signal Sd based on the display image signal Se to the optical engine 31, whereby FIG. As shown in FIG. 3, the captured image Gs1 is displayed on the screen 32.

  Next, when displaying each image based on the plurality of image data recorded in the memory card 4 as a list, the display changeover switch 54 of the remote controller 3 is operated. At this time, the main control unit 23 controls the memory card controller 15 in accordance with the operation signal So, for example, from the image data recorded on the memory card 4, for example, a predetermined number (for example, in the order of recording date and time) 9) is read out and output to the JPEG / MPEG decoder 16. Subsequently, the JPEG / MPEG decoder 16 decodes each image data and outputs each image signal Sb3. Next, the main control unit 23 causes the image processing unit 17 to execute the list display process 60 shown in FIG. In the list display process 60, the image processing unit 17 reads out from the memory card 4 whether or not each image signal Sb3 output from the JPEG / MPEG decoder 16 includes a signal obtained by decoding moving image data. It is determined whether or not each image data includes moving image data such as MPEG (step 61). In this case, when each of the image signals Sb3 is a signal obtained by decoding still image data (hereinafter also referred to as “still image data”), the image processing unit 17 performs a list display based on each image signal Sb3. The display image signal Se is output (step 62). Next, the element drive unit 19 outputs a drive signal Sd based on the display image signal Se to the optical engine 31, whereby the list display image Ga1 is displayed on the screen 32 as shown in FIG. In this case, in this list display image Ga1, nine captured images Gs1 to Gs9 (hereinafter, the contents of the captured images are distinguished) in nine sections S1 to S9 (hereinafter also referred to as “section S” when not distinguished) on the screen 32. When not, “photographed image Gs”) is displayed.

  Subsequently, when displaying a list of images based on the nine image data with the new recording date after the above nine image data, for example, the down arrow key (see FIG. 2) of the cursor key 55 on the remote controller 3 is operated. At this time, the main control unit 23 controls the memory card controller 15 and the JPEG / MPEG decoder 16 in the same manner as described above according to the operation signal So, and outputs each image signal Sb3 obtained by decoding the next nine image data. At the same time, the list processing 60 is executed by the image processing unit 17. In this case, when each image signal Sb3 includes, for example, one signal obtained by decoding moving image data, the image processing unit 17 determines that in step 61 and performs the moving display processing shown in FIG. 70 is executed (step 63).

  In the moving display processing 70, the image processing unit 17 determines whether or not extracted image data (which will be described later) is stored in the extracted image data storage unit 18 (step 71). In this case, since the extracted image data is not stored in the initial state, the image processing unit 17 performs a plurality of scenes (for example, every second from the beginning of the moving image based on the image signal Sb3 obtained by decoding the moving image data. (Six scenes) are extracted from the moving image data as a plurality of still images (hereinafter, the extracted still images are also referred to as “extracted images Gc”) to generate extracted image data for the extracted images Gc (step 72). . Next, the image processing unit 17 generates and outputs a display image signal Se for list display based on the extracted image data and the image signal Sb3 obtained by decoding the still image data (step 73).

  In this case, the image processing unit 17 specifically operates as follows in Step 72 and Step 73. First, until the extraction of the first extracted image Gc is started and finished, the original image to be extracted (hereinafter also referred to as “original image”) is a moving image as shown in the upper left diagram of FIG. For example, a display-type image signal Se for displaying, for example, a camera-type icon Gi indicating that there is a central portion of one predetermined section S where the extracted image Gc for the moving image is to be displayed is output. Next, when extracting the first extracted image Gc (extracted image Gc1 shown in the figure), the image processing unit 17 extracts the extracted image to the upper left position A in the section S as shown in the upper right figure of the figure. An image Gc1 is displayed, and a display image signal Se for displaying icons Gi at the upper right position B, lower left position C, and lower right position D in the section S is output. Next, when the second extracted image Gc (extracted image Gc2 shown in the figure) is extracted, the image processing unit 17 moves the extracted image Gc1 to the position B as shown in the lower left figure of the figure. The display image signal Se for displaying the extracted image Gc2 at the position A and displaying the icons Gi at the positions C and D is output.

  Thereafter, the image processing unit 17 extracts the third extracted image Gc3 to the sixth extracted image Gc6 as illustrated in the lower right diagram of FIG. 7 and the upper left diagram, the upper right diagram, and the lower left diagram of FIG. 8, respectively. Each time, the extracted image Gc and the icon Gi are displayed in the section S while moving the display position in the order of positions A, B, C, and D, and the extracted image Gc and the icon Gi displayed at the position D are displayed. A display image signal Se to be hidden is output. In this case, as shown in the upper left diagrams of FIGS. 7 and 8, after the extraction of the first extracted image Gc1 is started, the number of extracted images Gc that can be displayed in one section S (four in this example). The icon Gi is displayed in the section S until the extraction of is completed. Further, after the extraction of the extracted image Gc6 is completed, the image processing unit 17 displays the extracted images Gc1 to Gc6 while moving them in the above order in the section S as shown in the lower right diagram of FIG. The image signal Se is output at predetermined time intervals. In addition, when the image processing unit 17 generates the extracted image data for each of the extracted images Gc1 to Gc6 in step 72, the image processing unit 17 assigns a data name including a character string indicating the generation date and time and the data size of the moving image data to each extracted image. The extracted data is stored in the extracted image data storage unit 18.

  On the other hand, the element drive unit 19 outputs a drive signal Sd based on the display image signal Se output from the image processing unit 17 to the optical engine 31. As a result, the list display image Ga2 is displayed on the screen 32 as shown in FIG. In this case, in this list display image Ga2, for example, the captured images Gs10, Gs11, and Gs13 to Gs18 based on the still image data are displayed in the sections S1, S2, S4 to S9, respectively, and the section S3 is displayed at predetermined time intervals. Since the four extracted images Gc among the extracted images Gc1 to Gc6 are displayed while moving the respective display positions in the section S3, and the extracted images Gc1 to Gc6 are sequentially switched, each image displayed as a list is displayed. It is possible to reliably and easily determine whether the image is an image based on moving image data or an image based on still image data.

  Next, for example, the memory card 4 is taken out from the memory card slot 14, and image data is newly added (or partially deleted) by an external device (for example, a digital camera), and is recorded on the memory card 4. When displaying a list of images based on image data, the image signal changeover switch 53, the display changeover switch 54, and the cursor key 55 are operated after the memory card 4 is inserted into the memory card slot 14 in the same manner as described above. At this time, the main control unit 23 controls the memory card controller 15 and the JPEG / MPEG decoder 16 according to the operation signal So to output each image signal Sb3 obtained by decoding the nine image data. Then, the image processing unit 17 is caused to execute a list display process 60 (see FIG. 5). At this time, if each image signal Sb3 includes a signal obtained by decoding moving image data, the image processing unit 17 executes a moving display process 70 (see FIG. 6) (step 63). In this case, the image processing unit 17 searches the extracted image data storage unit 18 in step 71 of the moving display processing 70 to extract an extracted image having a data name including the same character string as the generation date and time and the data size of the moving image data. It is determined whether or not data is stored. When the corresponding extracted image data is stored, the extracted image data is read (step 74), and then the above-described step 73 is executed. For this reason, each extraction image Gc is displayed in a short time compared with performing the movement display process 70, extracting the extraction image Gc. Hereinafter, the main control unit 23 and the image processing unit 17 perform the above-described processes every time the image signal changeover switch 53, the display changeover switch 54, and the cursor key 55 are operated.

  As described above, according to the television 1 and the image reproduction program, when the image based on the image data read from the memory card 4 is a moving image in the list display processing 60, the moving display processing 70 is executed in the image processing unit 17. By doing so, when the image based on the image data is a moving image, a plurality of extracted images Gc extracted from the moving image can be displayed while moving the display position in the section S, so that a plurality of images are displayed in a list. In this case, the image based on the moving image data and the image based on the still image data can be visually recognized so as to be clearly identifiable. Therefore, according to the television 1 and the image reproduction program, it is possible to reliably and easily determine whether each image (or original image) displayed in a list is a moving image or a still image.

  Further, when extracting the extracted image Gc, even if it takes a lot of time to extract the extracted image Gc by displaying in the section S an icon Gi indicating that the original image of the extracted image Gc is a moving image. Thus, it can be surely and easily recognized that the original image is a moving image.

  Further, when the extracted image data to be processed by the moving display process 70 is stored in the extracted image data storage unit 18, the image processing unit 17 reads out the extracted image data and executes the moving display process 70. Each extracted image Gc can be displayed in a shorter time than when the moving display process 70 is executed while extracting the extracted image Gc.

  Further, by adding a data name including a character string indicating at least one of the generation date / time and the data size of moving image data to the extracted image data, the generation date / time and data size of the moving image data to be processed by the moving display processing 70 By comparing the extracted image data with the data name of the extracted image data, it is possible to reliably and easily specify whether or not the extracted image data corresponding to the moving image data is stored in the extracted image data storage unit 18.

  In addition, this invention is not limited to said structure. For example, although the example in which the display unit 20 is configured by including the optical engine 31 and the screen 32 has been described above, a CRT, a liquid crystal display panel, a plasma display, or the like may be employed as the display unit. Further, the example of displaying an image based on the image data recorded on the memory card 4 has been described above, but the present invention is not limited to the memory card 4 and is recorded on various storage elements and recording media such as a memory, CD, DVD, and hard disk. An image based on the image data being displayed can be displayed. In this case, these storage elements and recording media may be separate from the television 1 or may be built in the television 1. Moreover, although the example in which the present invention is applied to the television 1 has been described above, the present invention can be applied to various devices such as a digital camera, a video camera, a personal computer, a portable media player, a cellular phone, and a printer with a display unit. . The present invention can also be applied to an apparatus that does not include a display unit.

  Further, although the example in which six extracted images Gc are extracted in the moving display processing 70 has been described above, the number of extracted images Gc is not limited to this and can be arbitrarily set. Further, the extraction interval is not limited to the above-described one second, and can be arbitrarily set. Furthermore, only one of the number of extracted images Gc and the extraction interval is set, and the image processing unit 17 automatically sets the extraction interval and the number of extracted images Gc according to the length of the moving image (shooting time). It is also possible to adopt a configuration for setting to. Further, for example, a camera type icon Gi indicating that the original image is a moving image is displayed at the time of extraction of the extracted image Gc. However, characters, figures, and symbols indicating that the original image is a moving image are described above. , And combinations thereof can be displayed instead of the icons Gi. Furthermore, in the above configuration, the extracted image data is given a data name including a character string indicating both the recording date and time and the data size of the moving image data, but a data name including at least one of these character strings is given. Of course, you may do.
