Description

  The present invention relates to a digital stereo camera or a digital stereo video camera, a 3D display or a 3D projector, and a printer, and in particular, a digital stereo camera or a digital stereo video camera and a 3D display or 3D display with improved reproducibility of 3D stereoscopic images. The present invention relates to a 3D projector and a printer.

  3D stereo photographs and 3D stereo videos that allow viewers to view stereoscopic images by viewing two images taken from two different points of view left and right, with the left and right eyes, have a long history. In stereo photography, the positional matching of the left and right images is important in order to obtain a suitable stereo effect. If the matching is inconsistent, the stereo effect will be diminished and the eyes will be significantly fatigued. become.

  The applicant has already made many proposals for means for matching at the time of shooting and means for matching when a film is mounted on a slide mount in a conventional silver film type stereo camera or stereo slide. (Patent Documents 1, 2, 3 etc.).

In addition, as a technique of stereo photography in a digital camera, for example, a mirror type (prism type) stereo adapter having two right and left mirrors (prisms) is attached to a photographing lens of a general digital camera having one photographing lens, There has been proposed a technique for taking a stereo photograph by projecting an image incident on each of two right and left mirrors (prisms) separately into left and right halves of one image sensor (Patent Document 4).

As a 3D video viewing method for viewing 3D stereo video on a projection screen using a liquid crystal projector, etc., the left- eye image and the right- eye image are orthogonally polarized with each other, or circles whose rotation directions are opposite to each other. Polarized display and display on the projection screen, and the left eye and the right eye wear glasses with linear polarization filters or circular polarization filters corresponding to the above images, respectively, and images appearing on the left and right eyes are left Conventionally, a method of viewing 3D stereoscopic video by separating an eye side image and a right eye side image has been implemented.

In addition, when using a scanning electronic display such as a CRT or a liquid crystal display, a left- eye image and a right- eye image are alternately scanned one field at a time in interlaced scanning with one frame consisting of two fields. displaying, by the left eye side and the right eye liquid crystal shutters in synchronization with the CRT field scanning timing watch screen over the liquid crystal shutter glasses that open and close alternately, visible left eye side image to the left eye right 3D cinema system so that right eye image visible has been known (e.g. Patent Document 5).

  In stereo photography, positional matching of a pair of left and right images (adjustment of the distance at which the stereo composite image can be seen) is important, but for matching, not only the position of the main subject image in the left and right images, but also the shooting distance of the main subject There are various factors that affect visual matching, such as the distance between the optical axes of the left and right photographic lenses, and the positional relationship between the main subject image and other subject images and the background. It is known to be difficult to obtain.

  In other words, in order to create a high-quality stereo photograph, such as a stereo photograph that is not subjected to matching adjustment or a stereo photograph that is subjected to rough matching adjustment, the stereoscopic effect is adjusted for each shooting, or It is necessary to carry out each time a set of stereo photo prints or stereo slides is created. This is the same in 3D cinema, and matching adjustment should preferably be performed for each scene, but at present, technologies such as digital stereo cameras and 3D projectors equipped with matching adjustment means are not known. is there.

Thus, the left and right screen matching adjustment can be easily and accurately performed for each set of stereo photographs or scenes of the 3D cinema, and suitable stereo photograph printing or 3D cinema playback can be performed with the matching-adjusted image data.

  FIG. 1 shows an example of a digital stereo camera according to the present invention. A digital stereo camera 1 includes an imaging unit 2 and a stereo viewfinder 3 and has a stereoscopic matching adjustment function (masks the left or right end of an image). The stereo viewfinder 3 having a function) and the imaging unit 2 are coupled by, for example, a fitting mechanism 4 such as a hot shoe or an accessory shoe of a general camera, and electrically connected via an electrical contact 5 disposed in the fitting mechanism. Connected. At the time of editing after shooting, the imaging unit 2 and the stereo viewfinder 3 can be separated, and matching adjustment can be performed by the stereo viewfinder 3 alone.

  The image pickup unit 2 includes two digital cameras 8 each having a photographing lens 6 and a CCD image pickup device 7 (hereinafter simply referred to as an image pickup device 7), and a base 9 that supports the two digital cameras 8. The digital camera 8 is engaged with a guide rail portion 9a on the upper surface of the base 9, can be slid along the guide rail portion 9a, and can be fixed at an arbitrary position by a lock mechanism (not shown). Thus, the ability to adjust the distance between the optical axes of the left and right digital cameras 8 is particularly advantageous for close-up photography. This is because, in close-up photography, the distance between the optical axes set to the standard distance between the human eyes is often excessive, and a smaller distance between the optical axes is required.

  The stereo viewfinder 3 includes a pair of left and right TFT color liquid crystal displays (not shown) in the body, and images of a pair of left and right TFT color liquid crystal displays (hereinafter simply referred to as liquid crystal displays) are displayed as a pair of left and right eyepieces 10. It has a structure to observe separately. Although not shown, the body incorporates a display drive circuit, a display control unit having a stereoscopic sensation editing function, which will be described later, and an SD memory card (registered trademark) for storing image data or a compact flash (registered). Removable memory such as trademark and smart media (registered trademark) and a power battery are installed in each dedicated slot. Further, a power switch, a shutter button, an editing operation key, and the like are arranged at appropriate positions on the outer peripheral surface of the body.

  FIG. 2 shows a system camera 11 in which the digital stereo camera 1 is developed. The base 9 of the imaging unit 2 is attached to the top of the column 12, the stereo viewfinder 3 is attached to the upper and lower middle portions of the column 12, and the stereo viewfinder 3 is attached. A forehead pad 13 is attached above the head.

  A vertical grip 14 and a horizontal grip 15 in a direction perpendicular to the vertical grip 14 are provided at the lower portion of the column 12, and a shoulder pad 16 extends on the opposite side of the horizontal grip 15 extending to the left. The horizontal grip 15 is provided with a control switch portion 17 including an activation switch, zoom operation, focus adjustment, exposure adjustment, and other switch buttons, and the vertical grip 14 is provided with a photographing button 18. Although illustration is omitted, the forehead rest 13 and the shoulder rest 16 are equipped with a position adjusting mechanism, and hold the horizontal grip 15 and the vertical grip 14 with the left and right hands, respectively, and look into the eyepiece 10 of the stereo viewfinder 3. Then, the position of the forehead pad is adjusted so that the forehead pad 13 hits the forehead of the photographer, and the shoulder pad 16 is also adjusted to an appropriate position. If the start switch of the control switch unit 17 is turned on in this state, the image of the stereo viewfinder 3 can be monitored stably. When the shooting button 18 is pressed, stereo image data monitored with both eyes is recorded in the memory.

FIG. 3 is a diagram for explaining the parallax of the stereo camera, and shows a state where a subject (character F) at a short distance is photographed. The distance P _S between the centers of the imaging elements of the left and right imaging units is set equal to the distance P _L between the optical axes of the left and right imaging lenses. When shooting an infinite subject, light rays from the same point of the infinite subject enter the left and right photographing lenses 6 in parallel, so the distance between the centers of the left and right images formed on the left and right image sensors 7 P _I is equal to the distance P _L between the optical axes of the left and right photographing lenses 6. On the other hand, when shooting a subject at a finite distance as shown in FIG. 3, the center-to-center distance P _I of the subject image projected on the left and right imaging elements 7 is larger than the center-to-center distance P _S of the left and right imaging elements 7. Increased (P _I > P _S ).

FIG. 4 shows the full width of the original image data projected on the image sensor 7 of FIG. 3 in accordance with the screen widths of the left and right liquid crystal displays D, and the screen is viewed stereoscopically (of the eyepiece). Since the inverted image projected on the image pickup device of the stereo camera is displayed as an upright image rotated 180 degrees on the liquid crystal display D, the center-to-center distance P _I ′ between the left and right images is left and right. The distance is smaller than the distance P _D between the centers of the screens (P _I ′ <P _D ).

When stereoscopic such stereograph with both eyes, the stereoscopic image I _S looks in front of "stereo window" I _W, "stereo window" I _W is not fused to one, as shown two It looks out of place, making it unnatural and difficult to see. Therefore, in order to obtain a natural three-dimensional effect, it is necessary to adjust the matching of the left and right images.

In stereo photography, it is common sense that the subject at the shortest distance should be adjusted so that it can be seen at a distance equal to or longer than the “stereo window”. The viewfinder matching adjustment function may be adjusted so that the center-to-center distance P _I ′ of the subject image with the shortest distance is equal to or greater than the center-to-center distance P _D between the left and right screens.

  Fig. 5 shows the matching adjustment function of the stereo viewfinder. (a) is a short-distance subject image (letter F) on the image sensor rotated 180 degrees in an upright state. (b) is an image display area when the pair of left and right liquid crystal displays is edited (a state in which the aspect ratio is narrower than that at the time of shooting), and (c) is an image display area of (b) with no offset (a (D) is a state in which the inner vertical sides of the left and right images are made to coincide with the inner vertical sides of the image display area, and the distance between the centers of the left and right images is offset to the longest.

  Hereinafter, the procedure of matching adjustment will be described. An image projected onto the image sensor 7 at the time of shooting is monitored in real time by a stereo viewfinder 3 including a pair of liquid crystal displays D. When the shooting button is pressed, the image data over the entire imaging range of the image sensor 7 is recorded in the image memory.

  When performing the matching adjustment, the mode changeover switch is used to switch to the edit mode, and the image selection switch is pressed to display the stereo photograph on the liquid crystal display D sequentially (in any order) for each set. The initial position of the image that is redisplayed during editing is not limited.However, when the offset is zero in Fig. 5 (c), the left and right ends of the image are equally divided to the left and right of the display frame of the liquid crystal display. Excessive shielding (blackout).

  Matching adjustment is performed by using the scroll operation keys provided on the stereo viewfinder 3, and the right and left images are displayed by pressing either end of the scroll operation keys in the same way as a normal seesaw key for electric zooming operation. The state displayed on the liquid crystal display D by scrolling (offset) horizontally or offset symmetrically within the range of 5 (c) and Fig. 5 (d), adjusting to an appropriate scroll state, and then performing a save operation Are stored in the memory as a single piece of stereo image data.

As for the image display method during editing, the display frame size of the liquid crystal display D is reduced from the state of 100% field of view at the time of shooting to the narrow width shown in FIG. An image of the actual display screen width W _P that is narrower than the width W _O of the original image data is displayed on the monitor with the same width as the width W _{D of the} liquid crystal display, and the redisplay width when editing is also W _P There is a way to do it.

In either case, the original image data having the width W _O is recorded in the image memory. Although the former method can monitor the image over the entire width at the time of shooting, the screen at the time of re-displaying (during matching adjustment) becomes small. On the other hand, the latter method is not the entire display of the captured image at the time of shooting, but the display at the time of redisplay is enlarged to the width of the liquid crystal display, but there is an advantage that the screen width of the redisplay is not reduced. But you can.

  In the above embodiment, a configuration in which two independent image sensors are mounted as an image pickup unit has been described. However, a stereo image through left and right photographing lenses is divided into left and right images and projected onto one image sensor. May be.

In the first embodiment, the case where the distance P _L between the optical axes of the left and right photographing lenses 6 is equal to the distance P _S between the centers of the left and right imaging elements 7 has been described.In this case, as shown in FIG. In the state where the left and right center of the screen of the liquid crystal display D and the left and right center of the photographed image match and the object at infinity and the “stereo window” appear to be at infinity, the left and right ends of the photographed image are equally masked. .

As shown in Fig. 5 (d), when the left and right images are scrolled to the outermost end in the direction of moving outward, the mask amount inside the image becomes zero, and the "stereo window" has the shortest focusing distance. It looks equidistant from the subject. That is, since the offset adjustment range of the image is the range of the state of FIG. 5 (c) and the state of FIG. 5 (d), the masked portion outside the left and right images in FIG. It does not appear in the screen display range of the display, resulting in screen loss. In practice, even when an infinite subject is photographed, the stereoscopic effect is better if the “stereo window” is seen at a finite distance and the infinite subject image is seen on the other side.

FIG. 6 is a diagram for explaining means for improving the above-described image loss and stereoscopic effect. The selection range (width W _E ) at the time of editing on the exposure surface of the image sensor is set at the inner end between the left and right image sensors. In this case, the distance P _L between the optical axes of the left and right photographing lenses is set smaller than the distance P _E between the centers of the left and right editing selection ranges W _E at this time.

FIG. 7 (a) shows a case where the image taken with the camera of FIG. 6 is re-displayed on the liquid crystal display D of the stereo viewfinder 3 in the edit mode, and the outer edge of the original image data with the width W _O is the display. It is consistent with the outer end of the actual display screen W _P. FIG. 7B is an actual display screen (width W _P ) in the editing mode of the display D. Then, it is possible to offset to the inside edge of the original image data of the width W _O as shown in FIG. 7 (c) matches the inner end of the actual display screen W _P of the display.

In Fig. 7 (a), in order for the stereoscopic image F at infinity to be seen beyond the stereo window, that is, to make the stereo window appear at a finite distance, the left and right images on display D The center distance P _I ′ may be set to a distance larger than the center distance P _WP of the actual display screen of the display (P _I ′> P _WP ). When shooting a subject at a close distance, it is necessary to make the center-to-center distance P _I ′ of the left and right images on the display equal to the center-to-center distance P _WP of the actual display screen of the display, as shown in FIG. As shown, the center-to-center distance P _I ′ of the close-up subject image (letter F) is adjusted to be equal to P _WP (P _I ′ = P _WP ).

6, the image on the imaging element 7 are the inverted image, positional relationship between the erect finder becomes opposite, infinity image data selection range W of the left and right image pickup device camera during photographing _E is It approaches the innermost end of the entire width W _S of the image sensor.

The relationship between the image sensor and the _{display, W O: W S = W} P: is proportional to W _E, the distance between the centers of the data selection W _E of the imaging element 7 of the camera shown in FIG. 6 and P _E If the distance between the centers of the images on the left and right image sensors 7 is P _I and the distance between the optical axes of the left and right imaging lenses 6 is P _L , the light rays emitted from the same point at infinity are when entering the photographing lens 6, to become parallel to each other, the distance between the centers of the right and left images is equal to distance between the optical axes of the right and left photographing lenses 6, and _{P L = P I <P E} .

As described above, if the distance between the optical axes of the left and right photographing lenses 6 of the stereo camera is set to the above dimensional condition of P _L , the image loss in the example of FIG. 5 is eliminated and the image loss as shown in FIG. 7 is minimized. Stereo photo data can be obtained.

  Next, as a means for improving the visibility of the matching state, a case where a plurality of vertical line patterns P shown in FIG. 8 (a) and FIG. 8 (b) are displayed over the image on the liquid crystal display D will be described. To do. The vertical line pattern P is at the same position on the left and right editing screens, and when the left and right screens are viewed with both eyes, the left and right vertical line patterns P appear to match the distance of the “stereo window”. Then, it is only necessary to adjust the distance between the centers of the left and right images so that all subjects can be seen on the other side of the vertical line pattern P. Can be tested.

8 (a) is represents the selection from the original image data W _O when adjusted value at the time of matching adjustment of zero (the state of FIG. 7 (a)), FIG. 8 (b) If the adjustment value is maximum 8 shows the display range (the state shown in FIG. 7 (c)). Re-displaying during matching adjustment can be done from either direction, with the state shown in Fig. 8 (a) as the initial position and Fig. 8 (b) as the initial position, but it can be repeated in both directions for careful adjustment. It is desirable.

8 (a) and 8 (b) illustrate both ends of the adjustment value, but in reality, the adjustment is often performed between FIG. 8 (a) and FIG. 8 (b). In such a case, because both sides in the original image of the actual display screen width W _D on the liquid crystal display D of the left and right both are masked, look at the monitor at the time of editing, those who are interested in people of both the left and right of the three-dimensional field of view Depending on whether or not, the entire left and right images can be scrolled in the same direction. This adjustment can be performed up to the position of the final end (both left and right ends) of the pair of left and right image data.

The above matching adjustment, is performed by changing the distance between the centers of the left and right images by scrolling the image to display the display area of the predetermined width W _D, in pseudo zooming in place of the image scrolling It is also possible to use a certain digital zoom (a technique for enlarging the display by changing the readout ratio of video data stored in the image memory in a digital television or digital camera). You may comprise so that the center distance of the upper image may be changed.

  The image data edited by the matching adjustment can be stored in a memory as a single piece of image data in which the left and right images are integrated, and output to a digital silver halide printing system, a computer, a printer, or the like as needed. In the configuration in which the vertical line pattern P is superimposed and displayed at the time of editing, it is natural to store only the image data without superimposing the vertical line pattern data when storing the image data.

Next, a technique for facilitating the focus adjustment operation of a digital stereo camera using a liquid crystal display as a viewfinder will be described. For example, in the stereo viewfinder of the stereo camera shown in FIG. 6, the vertical line pattern P of FIG. 8 is displayed on the left and right liquid crystal displays by software control even during shooting. Then, in conjunction with the focus adjustment of the taking lens 6 at the time of shooting, the center-to-center distance P _E of the image selection range W _E on the left and right image sensors is changed, and the center-to-center distance between the left and right subject images that are in focus to match the P _E to P _I.

FIG. 9 illustrates a state in which the camera shown in FIG. 6 focuses on a short-distance subject at the time of shooting. As described above, the distance P _I between the centers of the short-distance subject images is the left and right photographing lenses 6. The dimension P _I > PL is larger than the center-to-center distance P _L.

In the state shown in FIG. 9, the center-to-center distance P _E of the image selection range W _E of the image sensor 7 is set to the minimum distance similarly to the center-to-center distance P _E in FIG. If the vertical line patterns are superimposed and displayed on the stereo viewfinder, the subject (letter F) looks close as shown in FIG. 10, and the photographer feels a lot of discomfort. In the state shown in FIG. 9, if the center-to-center distance P _I of the subject image is equal to the center-to-center distance P _E of the image sensor selection range W _E (P _E = P _I ), the vertical line pattern and the subject image Seem equal distances.

In FIG. 11, the image selection range is scrolled so that the state of P _E = P _I is reached (the selection range is moved in the direction of the state of FIG. 8B), and the distance between the centers of the left and right liquid crystal displays D center distance P _I of the image to be displayed as P _D 'is made to coincide with the _{(P D = P I')} . Therefore, the vertical line pattern appears at the same distance as the subject image in stereoscopic view at the time of shooting.

In order to set the stereo viewfinder so that the state of P _E = P _I shown in FIG. 9 is always set, in FIG. 9, the moving amount of the photographic lens in the optical axis direction during focus adjustment in FIG.
Focal length of taking lens… f
Distance from main point of photographic lens to object… L
Distance between optical axes of left and right photographic lenses… P _L
Distance between centers of images projected on left and right imaging elements… P _I
given that,
The amount of movement Δf of the photographic lens in the optical axis direction during focus adjustment is Δf = f ² / (L−f), and the center-to-center distance P _I of the image projected on the left and right image sensors is P _I = P _L (1 + Δf / f)
So as to satisfy the condition of Δf and P _I of the above equation, if conjunction with controlling the amount of horizontal scrolling left and right images in accordance with the focusing of the taking lens 6, the three-dimensional stereo viewfinder 3 as shown in FIG. 11 The image I _S appears equidistant from the “stereo window” I _W.

For example, when moving adjusting the photographic lens 6 manually, the position of the lens detected by the encoder or potentiometer, a horizontal scroll amount of the read range W _E of the original image data W _O so as to satisfy the above condition automatically The subject image may be seen at a position equidistant from the collimation pattern of the stereo viewfinder by interlocking adjustment. In the case of the auto-focusing type, it may be automatically controlled horizontal scroll amount of the read range W _E of the image data of the image pickup device from the in-focus distance data by calculation and allocation to meet the above equation.

  The above embodiment uses the vertical line pattern P as the collimation pattern, but is not limited to this. For example, if the left and right displays have the same shape and position, a circular index is used. These indicators may be used in combination with vertical lines.

  Conventional ordinary cameras cannot focus unless the focusing target or distance measuring means such as a reticle is aligned with the shooting target, but the method of the present invention can visually recognize the in-focus state in the entire field of view of the viewfinder, so An operation to match the target is not necessary. This is particularly important in shooting scenes in which subjects overlap multiple times. Even when the focusing mechanism of the camera of the present invention is designed to be an autofocus system, it is possible to focus on any subject distance at the time of shooting. Since it can be seen without changing the framing, it becomes very convenient.

  In the above description of the matching adjustment at the time of editing, the stereo photograph states that a subject image located at an infinite distance must be visible beyond the “stereo window”. This also applies to the sense of stereoscopic view of the viewfinder when the collimation pattern is displayed on the viewfinder at the time of shooting.

  Even when shooting at infinity, the distance from which the “stereo window” can be seen is preferably about 3 meters, but it may be set to 5 to 10 meters, for example. In stereo photography, it is often preferable to shoot in a pan-focus state. The aperture of the lens at the time of shooting is narrowed down, and focus adjustment is fixed at a distance of about 3 to 5 meters to focus from the foreground to the distant view. I often shoot it. However, in close-up shooting (close-up state) of about 1 meter or less, it is better that the subject image at the time of shooting be seen at a position equidistant from the collimation pattern.

This is because when the focus adjustment during shooting is adjusted to infinity, the image at infinity appears beyond the collimation pattern that appears at a distance of about 3 to 5 meters, and the focus adjustment is close to 1 meter or less. When the distance is adjusted, the above-mentioned Δ is set so that the subject image appears at a distance equal to the collimation pattern.
The focus adjustment value (Δf value) at the time of shooting calculated with f = f ² / (L−f) and P _I = P _L (1 + Δf / f) is linked with the selection range of the finder display. P _I is P _I '> P _D becomes, the short-distance P _I' shown in FIG. 11 may be an arithmetic control program to adjust the P _I 'values such that = P _D.

  Although the collimation pattern display color is preferably black, it may be difficult to see in a dark environment or a dark subject. As a countermeasure in such a case, the display control unit is provided with a collimation pattern display color switching function so that it can be switched between black and white, for example. Depending on the collimation pattern, it may be possible to identify the shooting mode or the editing mode by changing the color or shape.

  The stereo image matching technique described above can also be applied to 3D projectors and direct-view 3D displays. Since the technical contents apply the matching method in the digital stereo camera described above, the illustration is omitted, but will be easily understood in the following description with reference to FIGS. 3 to 11 as appropriate.

"Stereo window" I _W mentioned in the description of the digital stereo camera corresponds to a liquid crystal display, a CRT screen or projection screen of the 3D cinema system, the left and right image pickup element 7 projection lenses of the left and right projector 3D cinema system Corresponding to Then, a part of the lateral of the stereo views similar to the display area width W _E when matching adjustment of the liquid crystal display D of the finder 3, narrower aspect ratio than the aspect ratio of the left and right of the original image (original image as described above The left eye side image and the right eye side image are projected from a pair of left and right projectors in a masked state), or the left eye side image and right eye having an aspect ratio narrower than the aspect ratio of the left and right original images on an electronic display The side images are alternately displayed field by field.

  Then, if the projection area is selectively changed by horizontally scrolling the pair of left and right original images horizontally as shown in FIGS. The image frame on the CRT display or projection screen does not move, and the distance between the same subject image of the left eye side image and the right eye side image changes on the CRT or projection screen so that the matching state of the left and right images can be visually recognized. .

  The edited data of the scroll state can be written to an external storage medium such as an internal HDD or an internal DVD drive, or a removable memory or a removable disk device. In addition, as with a normal video editing system, you can specify any two points of frames separated by chapters or on the time axis, and edit the matching state of the scene. Can be adjusted.

  In addition, when editing a movie, by projecting a collimation pattern such as a plurality of vertical lines shown in FIG. 8 onto the images on the left and right electronic displays or projection screens, the relative distance between the projection screen and the subject image As described above, it is easy to visually recognize the three-dimensional effect.

  In addition, any frame can be extracted from stereo video data that has been edited and saved in an external storage medium such as an internal HDD or internal DVD drive, or in a removable memory or removable disk device, and sent to the outside as a pair of left and right stereo photo data. By outputting, a stereo photograph can be created from a moving image source.

  In order to reproduce a stereo photograph taken with a digital stereo camera on a 3D projector or a direct-view 3D display, a video signal of one field is generated from each of the left and right image data and displayed alternately on one display. Alternatively, the left and right image data may be distributed and supplied to the left and right projectors, respectively.

  For commercially available DVD software or video tapes that record moving images, for example, edited video data that has been matched to video data using pseudo 3D conversion software may be copied to another external storage medium. There is a risk of copyright problems. In this case, the software ID number and editing data (scrolling data for matching) and the chapter number and frame number related to the editing data are set as a set of data files. Save to the memory, read the software ID number during software playback, and sequentially control the horizontal scroll amount of the playback image for each chapter or specified scene based on the edit data file of the corresponding ID number stored in the memory What is necessary is just to comprise.

  The image data adjusted by matching editing with the above-described digital stereo camera or digital stereo video camera, or 3D display or 3D projector, is directly from the digital stereo camera or the like as a single stereo photo data, or from a memory By removing the image recording medium and attaching it to another reader device, a stereo photo print can be created by outputting to a printer or a digital silver halide printer.

In order to view a stereo photo print with a stereo viewer, it is necessary to cut the printed or developed stereo photo print into a shape suitable for the stereo viewer.
Also, in order to view a stereo photo print with a stereo viewer, it is better to provide a border (gap) between the left and right photos of the stereo photo print, and to provide a blank portion of a certain width around the left and right photos.

  When stereo photo data is sent to a printer, print data including a cutting guide frame that is the outer edge of the border and blank portion recorded in the memory is combined with the stereo photo data and output, and the cutting guide frame is printed together with the photo. As a result, the relative position between the outer shape of the stereo photographic print and the image becomes accurate.

  FIG. 12 shows an example of a stereo photo card, and the inside of the cutting guide frame 22 showing the outer shape of the stereo photo card 21 has a specific color or pattern except for images 24L and 24R arranged in parallel with the border 23 in between. The stereo photo card 21 having a fixed shape can be formed by cutting along the outer edge of the cutting guide frame 22.

  The reason why the left and right ends of the cutting guide frame 22 are arc-shaped is to facilitate insertion and positioning of the stereo photo viewer into the holder. The cutting guide frame line data may be stored in advance in the memory of the printer, and control may be performed so that frame data is automatically added and output during stereo photo printing.

  The means for performing stereo photo matching adjustment with the stereo viewfinder 3 described above can be applied not only to photographing devices and playback devices, but also to all printers such as commercial digital silver halide printers to consumer printers. For this, it is only necessary to mount two monitor displays on the left and right sides or one monitor display of a size that can display a pair of left and right stereo photographs at the same time.

  FIG. 13A shows an example of the printer 31 to which the monitor display 32 is attached (the operation switches and the like are not shown), and FIG. 13B shows the details of the monitor display portion. A flange 33 is formed on both the left and right sides of the monitor display 32, and a stereo viewer (eyepiece unit) 41 shown in FIG. The matching adjustment means by the printer is the same as that of the digital stereo camera described above, and will not be described here because the description is duplicated.

  In order to clearly view the two screens on the monitor display 32, a partition plate that partitions the left and right fields of view is necessary (if there is no partition, the fields of view of both the left and right eyes are interlaced). Necessary. However, in a printer, a monaural print may be displayed in a large size, or a large number of photographs may be displayed in an index, and a partition plate or an eyepiece is an obstacle during these operations.

  FIG. 14 shows a stereo viewer 41 that can be attached to and detached from the monitor display 32 portion of the printer 31. The stereo viewer 41 includes a lens board portion 42 and a print holder portion 43. The lens board portion 42 is fitted with a pair of left and right eyepieces 44L and 44R. The print holder 43 is provided with a pair of left and right windows 45L and 45R corresponding to a stereo image projected on the monitor display 32 of the printer 31 of FIG.

  The lens board part 42 and the print holder part 43 are respectively provided with partition plates 46 and 47 at the left and right central parts, and the partition plate 47 of the print holder part 43 is inserted into the partition board 46 having a box-shaped cross section of the lens board part 42. The lens board part 42 and the print holder part 43 are slidably connected to each other, and the diopter adjustment is performed by moving the lens board part 42 and the print holder part 43 close to or away from each other. To fix.

  A longitudinal groove 49 corresponding to the flange 33 of the monitor display 32 portion of the printer 31 is formed on the inner wall surfaces at the left and right ends of the back side of the print holder portion 43, and by engaging the longitudinal groove 49 with the flange 33, A stereo viewer 41 can be attached to the monitor display 32 of the printer 31. When the printer 31 is detached from the printer 31, a stereo photo print can be inserted into the vertical groove 49 of the print holder 43 of the stereo viewer 41 from above for viewing. The vertical groove 49 has a step with respect to the back surface of the window 45 of the print holder unit 43 so that the surface of the stereo photo print does not contact the back surface of the window 45 when the stereo photo print is inserted. This prevents the stereo photo print from being damaged. FIG. 15 shows another form of the stereo viewer 41, and various forms are conceivable, such as a shape obtained by removing the upper side portion of the print holder part 43 in this way.

  The present invention is not limited to the above-described embodiment, and various modifications are possible within the technical scope of the present invention, and it is natural that the present invention extends to those modifications.
