Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for capturing a three-dimensional image (three-dimensional image) by a capturing device such as a video camera having a built-in solid-state imaging device (CCD: Charge Coupled Device), and a device thereof.
[0002]
[Prior art]
Hitherto, as a three-dimensional image capturing device used for capturing a three-dimensional image, a four-mirror system disclosed in Japanese Patent Application Laid-Open No. H11-146424 has been known.
[0003]
This four-mirror system combines an optical attachment for capturing a stereoscopic image such as a still image or a moving image on a single video camera and captures images with parallax. An image with parallax is divided into right and left and taken in as shown in FIG. Then, 11 of the pair of left and right stereoscopic image by image processing (b), and expanded to 2-fold, respectively as _{(c) (A L, A} R), a display screen into a field sequential stereoscopic image signals And can be viewed stereoscopically with shutter glasses or the like.
[0004]
As described above, when the left and right images are enlarged twice by the image processing, the disparity is also enhanced by a factor of two, which causes eyestrain, and the amount of disparity changes depending on the size of the display. The amount of parallax increases.
[0005]
The present applicant has already disclosed in Japanese Unexamined Patent Application Publication No. 11-46373 a stereoscopic image capturing device (hereinafter, referred to as a prior application device) capable of obtaining a stereoscopic image in which the amount of parallax is suppressed to a necessary minimum and a burden on eyes is obtained. ).
[0006]
An example of this prior application will be described with reference to FIGS. 12 to 15. First, FIG. 12 shows internal parts housed in an optical attachment mounted on a video camera, and an image of 2.theta. The L image 11 is directly incident on the center point 10 by the camera photographed at an angle, and is taken in as the L image for the left eye.
[0007]
On the other hand, the R image 12 is reflected twice by the mirrors 13 and 14, enters the center point 10, and is taken in as an R image for the right eye. In this case, the R image 12 is equivalent to being incident toward the intersection 15 of the broken line. At this time, the distance d between R and L is reduced to about 1/4 as compared with the above-mentioned four-mirror system.
[0008]
Here, the right end 14R of the mirror 14 is on the optical axis 16 of the photographing lens 2, and the inclination angle of the mirror image 13 is the same as the inclination angle of the mirror 13 and the R image 12 incident at almost the same angle as the L image 11. Is set to be incident. In addition, the left end 13L of the mirror 13 is brought close to the optical axis 16 as long as it does not obstruct the left side light beam 17 of the L-side image information, so that the optical attachment can be significantly reduced in size.
[0009]
As a specific example, when designed for a camera whose focal length is 6 mm (horizontal angle of view is 43 degrees with a 1/3 inch CCD) and the position of the entrance pupil is 35 mm from the front of the taking lens, d is about 20 mm. Become. That is, the same parallax can be obtained as when two cameras were photographed 20 mm apart. The image obtained by this attachment is obtained by enlarging the left and right half images twice as large by the image processing disclosed in Japanese Patent Application No. 7-334423, so that the parallax is also doubled. This is equivalent to shooting two cameras 40 mm apart. This is somewhat smaller since the average interpupillary distance of the human right and left is 65 mm, but a sufficient stereoscopic effect can be obtained.
[0010]
Although the amount of parallax also changes depending on the size of the display, this will be described with reference to FIGS. 11, two cameras 20L, the distance 20R and _{d 1,} the camera 20L, and shows the positional relationship at the time of photographing A, C, B and an object arranged in order of proximity to 20R.
[0011]
When the convergence (the intersection of the optical axis centers of the left and right cameras) is adjusted to C, L and R images are obtained from the respective cameras as shown in FIGS. These are converted into field-sequential signals, reproduced on the display 21 as shown in FIG. 14, and viewed with the shutter glasses 22 such that the L image only enters the left eye and the R image only enters the right eye. C is located on the display 21, A is located on the front of the display 21, and B is located on the back of the display 21.
[0012]
Here, it can be seen that, when the video information is left as it is and is reproduced on the larger display 23 as shown in FIG. 15, all the parallaxes are expanded in the horizontal direction. As a result, the position of the image moves in the direction of the arrow shown in the figure. In this case, if the interval b between the images of B exceeds the human eye width (about 65 mm), fusion becomes difficult. An improper amount of parallax causes fatigue in stereoscopic vision.
[0013]
Regarding this point, the parallax amount in a method that provides a sense of depth by using the Pulfrich effect on an image moving in the left-right direction may be referred to. That is, if the light is weakened by attaching an ND filter to one eye, a transmission delay to the cerebrum occurs accordingly, and an image having a time difference between the left and right eyes is processed by the cerebrum and stereoscopically viewed. Although the delay is about 10 msec, a natural three-dimensional effect can be obtained even at a speed of 1 m per second. In this case, it is equivalent to a camera interval of 100 × 0.01 = 1 cm. From this, it can be seen that a minimum parallax amount is required for stereoscopic viewing. Although limited by the size of the lens and the horizontal angle of view, photographing with a parallax amount equal to or smaller than a 3D (three-dimensional) optical attachment to which the prior application is applied cannot be performed by other means.
[0014]
As described above, according to the prior application, in a video device that captures a three-dimensional image, the image for one of the eyes incident from a single lighting window is reflected on the right half of the imaging lens without being reflected by a mirror. Directly taking in, first and second mirrors are disposed opposite to each other through the one eye image light between the lighting window and the taking lens, and the other eye image light incident from the lighting window The angles of the first and second mirrors are respectively set to angles at which the light is reflected by the left half of the taking lens by reflection. As a result, the amount of parallax can be reduced to 1/3 to 1/4 as compared with the four-mirror system, and the image can be photographed from near to infinity with a deviation of ± 1.5 cm (on a 32-inch monitor) without adjustment. Therefore, a stereoscopic image with less burden on the eyes can be obtained.
[0015]
[Problems to be solved by the invention]
Although the invention of the prior application has the above-mentioned excellent features, there are the following problems when adjusting the focus (focus) of the camera by the incident light from the optical attachment (stereoscopic image capturing device). found.
[0016]
That is, the image light L for the left eye is directly incident (forming a through image) without passing through the mirrors 13 and 14, whereas the image light R for the right eye is reflected twice by the mirror and Since the optical path length is large, the amount of incident light is easily reduced. For this reason, if the focus (focus) and brightness of the camera are adjusted using the image light R for the right eye, error factors increase, the adjustment cannot be performed well, and a malfunction may be caused. is there.
[0017]
An object of the present invention is to provide a shooting method that enables accurate shooting by performing accurate distance measurement, brightness measurement, and the like, and performing optimum focus adjustment, aperture adjustment, shutter speed adjustment, and even white balance adjustment. To provide such a device.
[0018]
[Means for Solving the Problems]
That is, the present invention provides a photographing apparatus in which the image for one eye is positioned substantially in one half of the screen and the image for the other eye is positioned substantially in the other half of the screen using a stereoscopic image capturing means. In the method of shooting a three-dimensional image by
Without reflecting the image light for the one eye incident from a single lighting window with a mirror, directly capture into the substantially half of the taking lens corresponding to the image for the one eye,
A plurality of mirrors are arranged between the lighting window and the photographing lens to face each other via the image light for the one eye,
The stereoscopic image capturing means is configured to set the angles of the plurality of mirrors to angles at which the image light for the other eye incident from the lighting window is captured by the other half of the photographing lens by reflection. And
The present invention relates to a three-dimensional image photographing method, wherein the operation of the photographing device is adjusted using the one-eye image light, and a photographing device used for the photographing method.
[0019]
According to the present invention, the image light for one eye (for example, the image light for the left eye) of the light incident on the photographing device is incident with a short optical path length without passing through a mirror, and is thus transmitted to the photographing device. By using it for adjustment of operations such as focusing, accurate distance measurement and brightness measurement can be performed directly, and optimal focus adjustment, aperture adjustment, and shutter speed adjustment can be performed. Means: Optimal photographing without blurring, underexposure, and overexposure even when mounted, and even when color misregistration occurs due to a thin film (such as an oil film) attached to the mirror, the image light for the one eye is used. Can be directly observed and the white balance can be adjusted in this portion, so that color reproduction faithful to the real thing can be performed.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, based on the adjustment, it is preferable to perform the same adjustment on the video light for the other eye (for example, the video light for the right eye), for example, the through side (the video for the left eye). Adjust the white balance on the mirror side by adjusting the brightness of the image slightly higher than the focus position, adjusting the brightness of the image to match the brightness of the image on the through side, and reflecting the result of white balance adjustment on the through side on the mirror side. May be.
[0021]
In the viewfinder of the photographing device, the image other than the boundary between the image corresponding to the image for the one eye and the image corresponding to the image for the other eye, particularly, in the image corresponding to the image for the one eye, It is preferable to provide a photometry area in the area.
[0022]
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0023]
FIG. 1 schematically shows a photographing method according to the present embodiment. As shown in FIG. 12, an optical attachment (three-dimensional image capturing means) 31 has a 2θ of 2θ at the center point 10 of the entrance pupil. The L image 11 is directly incident on the center point 10 by the camera which is photographed at an angle of view, is taken in as the L image for the left eye, and the R image 12 is reflected twice by the mirrors 13 and 14 so that the center image is obtained. The light enters the point 10 and is taken in as an R image for the right eye.
[0024]
Other configurations are the same as those in FIG. 12, but the optical attachment 31 directly captures the image L for the left eye that enters from the single lighting window 44 into the right half of the photographing lens 2 without being reflected by the mirror. The mirrors 13 and 14 are arranged between the lighting window 44 and the photographing lens 2 so that the left-eye image light is interposed via the L, and the right-eye image light R entering from the lighting window 44 is photographed by reflection. By setting the angles of the mirrors 13 and 14 to the angles taken into the left half of the lens 2, the amount of parallax can be reduced to 1/3 to 1/4 as compared with the four-mirror system. By adjusting, it is possible to shoot from a short distance to infinity with a deviation of ± 1.5 cm (on a 32 inch monitor), so that a stereoscopic image with little burden on eyes can be obtained.
[0025]
In this case, the image light L for the left eye is directly incident without forming a mirror (a through image is formed), whereas the image light R for the right eye is reflected twice by the mirror and has an optical path length. , The light amount is likely to decrease. For this reason, if the focus (focus) and brightness of the camera are adjusted using the image light R for the right eye, there are many error factors, adjustment cannot be performed well, and a malfunction may occur. .
[0026]
However, as described above, by setting the incident light for camera adjustment to the image light L for the left eye, the incident light enters with a short optical path length without passing through a mirror. The measurement can be performed directly, and the optimal focus adjustment, aperture adjustment, and shutter speed adjustment can be performed, and even when the optical attachment is attached, it is possible to perform optimal photographing without blur, underexposure, and overexposure. Also, when color shift occurs due to a thin film (oil film, etc.) adhered to the mirror, the image light for the left eye can be directly observed and the white balance can be adjusted in this area, so that color reproduction faithful to the real thing can be achieved. It becomes possible.
[0027]
In this case, the non-through side (the image for the right eye) is set to be slightly farther (about 30 mm ac in the distance data) than the focus position on the through side (the image for the left eye), or the luminance of the image on the non-through side is 1 unit. It is possible to adjust the white balance on the mirror side by reflecting the result of the white balance adjustment on the through side to the mirror side. Good.
[0028]
In order to perform such adjustment, for example, from a CCD 60 that receives the image light L for the left eye, a measurement value such as the focus and the exposure amount of the image light is input to a CPU (Central Processing Unit) 61, and the CPU 61 For example, a control signal for adjusting the position of the taking lens 2 is input to the lens drive motor 62. Each of these components is incorporated in the camera housing.
[0029]
When the image light L for the left eye is used for adjustment as described above, as shown in FIGS. 2A, 2B, and 2C, a through image (a viewfinder image) of a finder is used to adjust focus and brightness. A photometry area such as a cross, a square area, or multiple points may be displayed at the center of the left-eye image). However, it is necessary to avoid the boundary between the left and right images at the adjustment position, and the influence of the image light on the mirror side becomes remarkable especially during zoom photographing. Therefore, it is desirable to surely avoid the boundary. The boundary corresponds to the end 14R of the mirror 14 shown in FIG. 1 and is a boundary between the left and right images, so that the incident light for the left eye is disturbed. In the case of the multi-point type shown in FIG. 2C, the incident light can be detected on average, so that the adjustment can be made not only on the left side but also on the right side (mirror side) if the boundary is avoided. .
[0030]
FIGS. 3 to 6 show an adapter for mounting the optical attachment (stereoscopic image capturing means) 31 according to the present embodiment, and a video camera (herein, a digital still camera: hereinafter, abbreviated as a digital camera) using the adapter. And a moving image as well as a still image).
[0031]
As shown in FIGS. 3 to 5, the adapter 30 is entirely formed of substantially translucent or transparent plastic, and an optical attachment (three-dimensional image capturing means) 31 is attached to the adapter 30.
[0032]
At the time of this attachment, as shown in FIG. 4, a notch 34 formed on the inner periphery of a circular ring portion 33 formed on the adapter 30 corresponding to the cylindrical shape of the circular ring portion 32 of the optical attachment 31. After the projection 35 formed on the outer periphery of the ring portion 32 of the optical attachment 31 is fitted, the optical attachment 31 is slightly rotated around the optical axis 16 to fix the position, so that the optical attachment 31 The attachment 31 is fixed at a regular position as shown in FIG. Then, by performing the reverse operation, the optical attachment 31 can be removed from the adapter 30.
[0033]
The optical attachment 31 is schematically shown in cross section in FIG. 6, but the internal structure and function are the same as those shown in FIG. That is, the optical attachment 31 causes the digital camera 37 to display an image for one eye (here, for the left eye) on substantially one half of the screen and an image for the other eye (here, for the right eye) on the screen. Each image light is incident so as to be located at substantially the other half of the lens, but substantially one half of the photographing lens 2 is reflected without reflecting the image light for one eye incident from a single lighting window 44 with a mirror. And a plurality of mirrors 13 and 14 are arranged between the lighting window 44 and the photographing lens 2 via the image light for one eye so as to face each other. The angles of the plurality of mirrors 13 and 14 are set to angles at which the image light is taken into substantially the other half of the photographing lens 2 by reflection.
[0034]
As shown in FIGS. 3 and 4, the adapter 30 has an upright portion 36 provided with a circular ring portion (annular portion) 33. As shown in FIG. Is applied to the front surface of the housing 49. At approximately right angles to the standing plate portion 36 in the front-rear direction, a fixed plate portion 38 is fixedly provided in contact with and fixed to the bottom surface of the housing 49 of the digital camera 37. It is shaped like a letter.
[0035]
The ring portion 33 of the adapter 30 has an inner peripheral surface 42 that is inscribed and fitted into an outer peripheral surface 41 of a ring portion 40 that accommodates a lens barrel 39 with a built-in lens of the digital camera 37 so as to be able to enter and exit. . The inner peripheral surface 42 corresponds to the height position of the lens barrel portion 39 depending on the model of the digital camera 37, and as shown in FIG. 7, the ring portion 40 when the lens barrel portion is at the upper position. A first arc surface 42A of a center 43A coinciding with the outer peripheral surface of the ring portion 40, and a second arc surface 42B of a center 43B coincident with the outer peripheral surface of the ring portion 40 when the lens barrel is at the lower position. One of the arc surfaces is inscribed in the corresponding outer peripheral surface 41 of the ring portion 40 having a predetermined height.
[0036]
Accordingly, even if the height of the lens barrel portion 39, that is, the ring portion 40 differs depending on the model of the digital camera 37, the outer circumference of the ring portion 40 is accordingly changed to the inner circumference 42A of one of the ring portions 33 of the adapter 30. Alternatively, the center of the ring portion 33 of the adapter 30 can be easily and accurately adjusted to the center of the regular lens barrel simply by being joined to 42B.
[0037]
The fixing plate 38 provided at the bottom of the adapter 30 has screw holes 47A and 47B formed therein. The screw holes 47A and 47B are originally for fixing a tripod of the digital camera 37. And are formed at different positions depending on the camera model. Then, without using a tripod, as shown in FIG. 8, for example, a screw 48 is screwed into the housing 49 of the digital camera 37 from one of the screw holes 47A, thereby fixing the fixing plate 38 to the bottom surface of the camera housing 49. Removably screw. The fixing plate portion 38 is formed with a positioning small hole 55 which is fitted into a small projection (not shown) provided on the camera housing.
[0038]
In this case, if the screwing position is changed according to the camera model, the fixing plate 38 can always be fixed to the camera housing 49 according to the camera model. An L-shaped positioning ridge 50 is formed in advance on a corner of the fixing plate 38 on the camera housing side. As shown in FIG. The above-mentioned screwing is performed by determining the positional relationship between the two by engaging the projections 51 of 49 with the projections and depressions. As a result, the fixing plate 38 can be always fixed at a regular position with respect to the camera housing 49.
[0039]
Further, in the fixed plate portion 38, a protruding plate portion 52 projecting substantially perpendicularly downward is integrally provided below the ring portion 33. The protruding plate portion 52 serves as a leg portion when the adapter 30 is attached to the camera housing 49 as shown in FIG. 9A and is mounted on the mounting surface 53 as shown in FIG. 9B. In addition, a lower end surface 54 in contact with the mounting surface 53 is provided in parallel with the fixed plate portion 38.
[0040]
Therefore, the lower end of the protruding plate portion 52 and the lower end of the fixed plate portion 38 are supported on the mounting surface 53 in contact with each other. Since there is no impact force or the like, these mirrors can be always maintained in a normal state.
[0041]
A window 46 facing the finder 45 of the digital camera 37 is provided above the standing plate 36 of the adapter 30. For example, a half 46A of the window 46 corresponding to the video light for the right eye is shielded. Processing or processing for reducing the amount of transmitted light, for example, embossing or blackening processing, is performed, and the other half 46B has sufficient translucency without being subjected to such processing.
[0042]
That is, when a target image is viewed from the finder 45 with the optical attachment 31 attached to the digital camera 37, for example, video light for the left eye enters through the light transmitting portion 46B of the window 46 of the adapter 30. The image light for the right eye does not enter from the half portion 46A subjected to the light shielding processing or the transmitted light amount reducing processing, or enters only with a low light quantity. FIG. 10 is a schematic diagram showing the state.
[0043]
Therefore, when the adapter 30 is attached to the camera and used, the image for the left eye can be focused on at the time of shooting, so that a good image can always be reproduced on the screen of the display, and the shooting state can be displayed. You can check. Also, if the adapter 30 is removed from the camera, it can be used as a normal digital camera that does not reproduce a stereoscopic image.
[0044]
Further, since the adapter 30 is made of a translucent material, the state of the inside of the adapter 30 can be checked from the outside, so that it is easy to handle and attach to the camera, and it is also easy to check the attachment state. .
[0045]
The embodiments described above can be variously modified based on the technical idea of the present invention.
[0046]
For example, the components and arrangement of the mechanism for adjusting the operation of the above-described camera may be variously changed, and as the incident light for adjustment, the image for the right eye may be changed so as to form a through image. Light may be used.
[0047]
Further, the shape, size, material and the like of the adapter 30 may be variously changed, and in particular, the position defining means and the fixing means at the time of attachment to the camera are not limited to those described above. Further, the adapter 30 and the optical attachment 31 may be integrated, for example, may be integrally formed. In this case, the optical attachment 31 can be arranged at a regular position as designed during molding, which is advantageous. The screw holes 47A and 47B may not be individually formed, but may be formed in a long hole shape and screwed at a desired position in the long hole.
[0048]
The object to which the adapter 30 and the optical attachment 31 are attached is not limited to the digital camera described above, but may be another video camera as long as it has a CCD, magnetic disk, or magnetic tape recording function.
[0049]
In addition, the above-described video for each eye is reproduced not only on a display separate from the camera but also on a monitor screen attached to the camera, and this monitor is provided with a finder function as described in FIG. The video for the left eye may be monitored.
[0050]
Further, the present invention is effective not only for still images but also for moving images. In addition, the present invention is not limited to the above-described stereoscopic image observation by the shutter glasses method, and can be applied to well-known general stereoscopic image observation using parallax due to polarization or the like.
[0051]
