  The present invention relates to an image generation method, a stereoscopic print, a method for manufacturing a stereoscopic print, and a program.

Conventionally, a left-eye image taken with a camera corresponding to the left eye and a right-eye image taken with a camera equivalent to the right eye are prepared, and these images are synthesized by anaglyph processing, etc. A technique for obtaining an image for use (stereoscopic print) is known. For example, Patent Documents 1 and 2 are known as conventional techniques for such a stereoscopic viewing method.
JP 2000-56411 A Japanese Patent Laid-Open No. 2004-178579

  However, in the conventional stereoscopic viewing method, one subject (object, object) to be stereoscopically viewed is photographed only once with the left-eye camera and the right-eye camera to create a stereoscopic image. That is, it has not been performed to shoot and synthesize different subjects. This is because an appropriate composite image can be obtained by simply synthesizing the stereoscopic image obtained by photographing the first subject and the stereoscopic image obtained by photographing the second subject. It is not possible.

  According to some aspects of the present invention, it is possible to provide an image generation method, a stereoscopic printed material, a stereoscopic printed material manufacturing method, and a program that can appropriately synthesize stereoscopic images of the first and second objects. .

  The present invention is an image generation method for generating an image for stereoscopic vision, which acquires a first left-eye image and a first right-eye image for a first object, and obtains a first object for a second object. The second left-eye image and the second right-eye image are acquired, and the acquired first left-eye image and the second left-eye image are combined to generate a third left-eye image. The first right-eye image and the second right-eye image are combined to generate a third right-eye image, and based on the generated third left-eye image and the third right-eye image. The present invention relates to an image generation method for generating the stereoscopic image.

  According to the present invention, the first left-eye image for the first object and the second left-eye image for the second object are combined to generate a third left-eye image. In addition, the first right-eye image for the first object and the second right-eye image for the second object are combined to generate a third right-eye image. Then, a stereoscopic image is generated based on the generated third left-eye image and third right-eye image. If it does in this way, the image for stereoscopic vision about the 1st and 2nd object is combined appropriately, and the image for stereoscopic vision appropriately expressed about the stereoscopic vision of both the 1st and 2nd object is obtained. It becomes possible.

  In the present invention, the layer for storing the first left-eye image and the layer for storing the second left-eye image are combined to generate the third left-eye image, and The third right-eye image may be generated by layer combining a layer in which one right-eye image is stored and a layer in which the second right-eye image is stored.

  In this way, the left eye image and the right eye image can be independently synthesized using layer synthesis.

  In the present invention, an image other than the image of the first object in the first left-eye image is trimmed, and an image other than the image of the second object in the second left-eye image is trimmed. Then, a layer in which the first left-eye image after trimming is stored and a layer in which the second left-eye image after trimming is stored are combined, and the first of the first right-eye images is Trimming an image other than the image of one object, trimming an image other than the image of the second object in the second right-eye image, and storing the first right-eye image after trimming. The layer and the layer in which the second right-eye image after trimming is stored may be combined.

  By performing such trimming, when the first and second objects have a vertical relationship, it is possible to appropriately combine the images of the first and second objects.

  In the present invention, the correction processing for eliminating the perspective of the image on the reference plane at least in the depth direction includes the first left-eye image, the first right-eye image, the second left-eye image, Performing the second right-eye image, combining the first left-eye image after the correction process and the second left-eye image after the correction process to generate the third left-eye image; The first right-eye image after the correction process and the second right-eye image after the correction process may be synthesized to generate the third right-eye image.

  If correction processing is performed to eliminate the perspective of such an image on the reference plane (for example, an image of the reference plane itself or an object image in contact with the reference plane), there is little inconsistency in focus adjustment or depth, Realistic and natural stereoscopic vision can be realized.

  In the present invention, binocular parallax adjustment is performed on the first left-eye image and the first right-eye image, and the height of the reference plane for the first object in stereoscopic view is adjusted. Also good.

  In this way, after obtaining the first left-eye image and the first right-eye image, the height of the reference plane for the first object appearing in these images can be arbitrarily adjusted. It is possible to realize fine adjustments in vision and various stereoscopic expressions.

  In the present invention, the binocular parallax adjustment may be performed by shifting the first left-eye image in either the left direction or the right direction, and changing the first right-eye image to the other one different from the one. It may be a process of shifting in the direction.

  In this way, binocular parallax adjustment can be realized by simply shifting the first left-eye image and the first right-eye image leftward or rightward, and the adjustment can be simplified.

  In the present invention, binocular parallax adjustment is performed on the second left-eye image and the second right-eye image to adjust the height of the reference plane for the second object in stereoscopic view. Also good.

  In this way, after obtaining the second left-eye image and the second right-eye image, the height of the reference plane for the second object reflected in these images can be arbitrarily adjusted, It is possible to realize fine adjustments in vision and various stereoscopic expressions.

  Further, in the present invention, the binocular parallax adjustment is performed by shifting the second left-eye image in either the left direction or the right direction, and changing the second right-eye image to the other one different from the one. Adjustment that shifts in the direction of may be possible.

  In this way, binocular parallax adjustment can be realized by simply shifting the second left-eye image and the second right-eye image leftward or rightward, and the adjustment can be simplified.

  In the present invention, the second object may be an object that floats above the first object.

  In the present invention, a left-eye shadow image and a right-eye shadow image for the shadow of the second object are generated, and the first left-eye image, the second left-eye image, and the left-eye shadow image are synthesized. The third left-eye image is generated, and the first right-eye image, the second right-eye image, and the right-eye shadow image are combined to generate the third right-eye image. Good.

  In this way, it is possible to generate a stereoscopic image that is expressed also about the shadow of the second object, and to improve the quality and realism of the stereoscopic image.

  In the present invention, the binocular parallax information at the location where the shadow of the second object falls is acquired based on the first left-eye image and the first right-eye image, and the acquired binocular Based on the parallax information, binocular parallax adjustment may be performed on the left-eye shadow image and the right-eye shadow image.

  In this way, it is possible to prevent a situation where a shadow is seen at a position floating from the first object during stereoscopic viewing, and to realize stereoscopic viewing in which more natural and realistic shadows are expressed.

  In the present invention, the blurring process of the left eye shadow image and the right eye shadow image may be performed based on the height information of the second object.

  In this way, it is possible to provide a realistic stereoscopic image in which a shadow whose blur condition changes according to the height is expressed.

  In the present invention, the stereoscopic image may be generated by performing anaglyph processing of the generated third left-eye image and the third right-eye image.

  Note that stereoscopic images other than anaglyphs may be generated.

  In the present invention, an image without binocular parallax may be further combined with the generated stereoscopic image.

  In this way, it is possible to provide a stereoscopic image in which an image such as a logo or a character having no binocular parallax is expressed.

  Hereinafter, this embodiment will be described. In addition, this embodiment demonstrated below does not unduly limit the content of this invention described in the claim. In addition, all the configurations described in the present embodiment are not necessarily essential configuration requirements of the present invention.

1. Stereoscopic Technique of Present Embodiment FIG. 1 is a flowchart for explaining the stereoscopic technique (stereoscopic image generation technique) of the present embodiment.

  First, a first left-eye image IL1 and a first right-eye image IR1 for the first object OB1 are acquired (step S1). Specifically, as shown in FIG. 2A, the object OB1 is arranged (set) on the reference plane BS. For example, an object OB1 (object, base object, base object) that is a subject is placed on a table (a table on which a white mount is placed) that serves as a reference plane BS. Then, a left-eye image IL1 that is visible from the left-eye viewpoint position VPL and a right-eye image IR1 that is visible from the right-eye viewpoint position VPR are acquired.

  Here, the left-eye and right-eye viewpoint positions VPL and VPR are positions assumed as positions of the left eye and right eye of the viewer. For example, when the left-eye and right-eye images IL1 and IR1 are created by actual shooting by a camera (digital camera or the like), the cameras are arranged at the positions of these VPL and VPR, and the left-eye and right-eye images IL1 and IR1. Shoot. In this case, two cameras may be arranged in the VPL and VPR and photographed at the same time, or the position of one camera may be changed and photographed. On the other hand, when the left-eye and right-eye images IL1 and IR1 are generated by a system that generates CG (Computer Graphics) images and game images (real-time moving images), a virtual camera (in a broad sense) is placed at the position of these VPL and VPR. Are arranged to generate left-eye and right-eye images IL1 and IR1. That is, an image that can be seen from VPL and VPR in the object space is generated.

  Note that the reference plane BS is, for example, a plane that is oblique with respect to the line-of-sight direction SL (a direction connecting the viewpoint position and the gazing point) and is a plane that is not orthogonal to the line-of-sight direction SL. That is, the reference plane BS is a plane different from the perspective projection screen that is always orthogonal to the line-of-sight direction SL. This reference surface BS corresponds to the surface on which the stereoscopic printed material is placed during stereoscopic viewing. The reference plane is not limited to two, and three or more reference planes (a plurality of linked reference planes) may be used.

  Next, a second left-eye image IL2 and a second right-eye image IR2 for the second object OB2 are acquired (step S2). Specifically, as shown in FIG. 2B, the second object OB2 is arranged (set) on the reference plane BS. For example, an object OB2 (object, floating object, floating object) that is a subject is placed on a table that serves as a reference plane BS (a table on which a white mount is placed). Then, a left-eye image IL2 that is visible from the left-eye viewpoint position VPL and a right-eye image IR2 that is visible from the right-eye viewpoint position VPR are acquired. For example, when the left-eye and right-eye images IL2 and IR2 are created by actual shooting by the camera, the cameras are arranged at these VPL and VPR positions, and the left-eye and right-eye images IL2 and IR2 are photographed. On the other hand, when the left-eye and right-eye images IL2 and IR2 are generated by a system that generates CG images and game images, virtual cameras are arranged at the positions of these VPL and VPR, and the left-eye and right-eye images IL2, IR2 is generated.

  Next, as shown in A1 of FIG. 3, the left-eye image IL1 for the object OB1 acquired in step S1 and the left-eye image IL2 for the object OB2 acquired in step S2 are combined to form the third left-eye. A production image IL3 is generated (created and acquired) (step S3).

  Specifically, for example, a layer in which the left-eye image IL1 is stored (first left-eye layer) and a layer in which the left-eye image IL2 is stored (for the second left eye above the first left-eye layer) Layer) is combined (integrated) to generate a left-eye image IL3. More specifically, an image other than the image of the object OB1 in the left-eye image IL1 is trimmed, and an image other than the image of the object OB2 in the left-eye image IL2 is trimmed, and the trimmed left-eye image IL1 is stored. And the layer in which the trimmed left-eye image IL2 is stored are combined.

  Next, as shown in A2 of FIG. 3, the right-eye image IR1 for the object OB1 acquired in step S1 and the right-eye image IR2 for the object OB2 acquired in step S2 are combined to form the third right-eye. A production image IR3 is generated (created and acquired) (step S4).

  Specifically, for example, a layer storing the right-eye image IR1 (first right-eye layer) and a layer storing the right-eye image IR2 (for the second right eye above the first right-eye layer) Layer) is combined (integrated) to generate a right-eye image IR3. More specifically, the image other than the image of the object OB1 in the right-eye image IR1 is trimmed, and the image other than the image of the object OB2 in the right-eye image IR2 is trimmed, and the trimmed right-eye image IR1 is stored. The layer to be combined with the layer in which the trimmed right-eye image IR2 is stored.

  Next, as shown at A3 in FIG. 3, a stereoscopic image IST is generated (created) based on the left-eye image IL3 generated in step S3 and the right-eye image IR3 generated in step S4 (step) S5). Specifically, for example, an anaglyph process is performed based on the left-eye image IL3 and the right-eye image IR3 to generate the stereoscopic image IST.

  Then, the stereoscopic image generated in step S5 in FIG. 1 is printed on a print medium using a color printer (printer in a broad sense) such as an ink jet method or a laser printer method, so that a stereoscopic printed matter is obtained. Can be manufactured. In addition, you may manufacture the printed material for stereoscopic vision by duplicating the printed material for stereoscopic vision used as the original disc printed by the color printer (printing machine). In this way, there is an advantage that a large amount of stereoscopic printed material can be manufactured in a short period of time.

  Then, the stereoscopic print manufactured in this way is provided with, for example, a red filter (may be a filter other than red) on the left eye and a blue (turquoise) filter (may be a filter other than blue) on the right eye. Stereoscopic viewing can be realized by viewing with stereoscopic glasses. Note that stereoscopic viewing may be realized by providing a lenticular lens on the printed material or using a lenticular lens as a print medium.

  If the stereoscopic image is displayed on the display unit of the image generation system, a game image (moving image) can be generated in real time. In this case, a stereoscopic image obtained by anaglyph processing or the like is directly displayed on the display unit, and this is viewed using glasses (equipment in a broad sense) provided with color filters (red and blue). You may do it. Alternatively, the left-eye and right-eye images IL3 and IR3 may be alternately displayed in different frames, for example, on the display unit and viewed using glasses equipped with a liquid crystal shutter or the like. Alternatively, a stereoscopic view may be realized by providing a lenticular lens in the display unit of the image generation system.

  According to the above-described stereoscopic viewing method of the present embodiment, as shown in FIGS. 2A and 2B, the images of the objects OB1 and OB2 obtained (captured) separately by a camera or the like are combined, A stereoscopic image in which these objects OB1 and OB2 are stereoscopically displayed can be generated.

  For example, in FIG. 2A, the object OB1 is assumed as a base object, and the object OB2 is assumed as a floating object floating above the object OB1. Specifically, the object OB2 is floated by being supported by a support bar or the like, and the object OB2 is photographed. In this case, in the left-eye image IL2 and the right-eye image IR2, in addition to the object OB2, a support rod and a shadow SD of OB2 are captured.

  As described above, it is difficult to generate a stereoscopic image that represents a state in which the object OB2 is floating above the base object OB1 by only one shooting. For this reason, in FIG. 2A and FIG. 2B, photographing for the object OB1 and photographing for the object OB2 are divided into two times.

  In this case, for example, a first stereoscopic image is generated from the left-eye image IL1 and the right-eye image IR1 obtained in FIG. 2A, and the left-eye image IL2 and the right-eye image obtained in FIG. It has been found that even when a second stereoscopic image is generated from the image IR2 and the first and second stereoscopic images are combined, proper stereoscopic viewing of the objects OB1 and OB2 cannot be realized.

  Therefore, in the present embodiment, first, the left-eye image IL1 obtained in FIG. 2A and the left-eye image IL2 obtained in FIG. Further, the image for right eye IR1 obtained in FIG. 2A and the image for right eye IR2 obtained in FIG. Then, as shown in A1, A2, and A3 of FIG. 3, a stereoscopic image IST is generated based on the left-eye image IL3 and the right-eye image IR3 obtained by the synthesis. That is, the anaglyph processing is performed after the left and right layers separately for each image of the objects OB1 and OB2 are integrated separately.

  In this way, it is possible to obtain an appropriate stereoscopic image in which both the objects OB1 and OB2 are reflected. In other words, it is possible to obtain a stereoscopic image that is appropriately expressed for the stereoscopic vision of both the objects OB1 and OB2. In addition, it is possible to generate a stereoscopic image that is difficult to generate by one shooting, such as an object OB2 floating on the object OB1.

2. Correction Processing In the present embodiment, it is desirable to perform the following correction processing on the left-eye image and the right-eye image. Specifically, the correction processing for eliminating the perspective of the image on the reference plane BS is acquired in the left-eye image IL1 and the right-eye image IR1 acquired in step S1 of FIG. 1 or in step S2. For the left-eye image IL2 and the right-eye image IR2. In step S3, the corrected left eye image IL1 and the corrected left eye image IL2 are combined to generate a left eye image IL3. In step S4, the right-eye image IR1 after correction processing and the right-eye image IR2 after correction processing are combined to generate a right-eye image IR3.

  Here, the correction process for eliminating the perspective in the present embodiment is, for example, a correction process for eliminating the perspective at least in the depth direction of the image on the reference plane BS. This correction process may include a convergence angle correction process. More specifically, as shown in FIG. 4A, this correction processing is performed on an image of the reference plane BS itself, an image IM1 drawn on the reference plane, and images of the objects OB1 and OB2 (objects). Of these, it is a process of eliminating the perspective (depth feeling) for the image of the part in contact with the reference plane BS. That is, in B1 of FIG. 4A, the distance between the vertices becomes narrower as it goes from the viewpoint to the back side, but in B2 of FIG. 4A, the distance between the vertices changes even if it goes from the viewpoint to the back side. Absent. By performing such correction processing, an image as if viewed from directly above is created (generated) for the image of the reference surface BS. Note that the perspective does not need to be completely eliminated by this correction process, and it is sufficient that the perspective disappears to such an extent that a sense of incongruity does not occur.

  For example, in a conventional general stereoscopic method, as shown in FIG. 4B, a stereoscopic printed matter PM (or a display screen of a display unit; the same applies to other explanations), the plane of which is parallel to the vertical plane. It was assumed that the viewer would see the stereoscopic printed material PM facing the person.

  In this regard, in the stereoscopic viewing method in which the correction processing of FIG. 4A is performed, as shown in FIG. 4C, the viewer places the stereoscopic printed matter PM (display screen) on a mounting surface (reference) such as a desk. It is assumed that they are arranged on a surface corresponding to the surface BS and viewed from an oblique direction. That is, such an arrangement is a default arrangement. When the stereoscopic printed matter PM is arranged in parallel to the horizontal plane in this way, if the correction process is not performed, a contradiction occurs in the perspective.

  Therefore, in FIG. 4A, correction processing is performed to eliminate the perspective in at least the depth direction of the image of the reference plane. Then, anaglyph processing or the like is performed based on the corrected image without the perspective on the reference plane to create a stereoscopic printed matter PM, and the created stereoscopic printed matter PM is horizontal as shown in FIG. If they are arranged in parallel, the image of the reference plane has an appropriate perspective. Further, when arranged as shown in FIG. 4C, the focal lengths of the respective points on the surface of the stereoscopic printed matter PM are not the same but different. For this reason, the focus adjustment is similar to that in the real world. Therefore, the shift in the relationship between the focus adjustment and the binocular parallax and the convergence is reduced, and a more natural and realistic stereoscopic vision can be realized.

3. Anaglyph Processing Next, anaglyph processing will be briefly described. In the anaglyph process, the left-eye image and the right-eye image are printed on a single print medium with different colors to create a stereoscopic print. The stereoscopic print is viewed through different color filters (for example, the left eye is red and the right eye is blue) between the left and right eyes. At this time, only the image for the left eye can be seen with the left eye, and only the image for the right eye can be seen with the right eye, thereby realizing stereoscopic viewing.

  For example, in monochrome anaglyph processing, the image for the left eye IL3 is converted to gray scale. Then, the converted image data is copied to the R channel of the anaglyph image (RGB). Next, the right-eye image IR3 is converted into a gray scale. Then, the converted image data is copied to the G channel and B channel of the anaglyph image (RGB). Thereby, a monochrome anaglyph image is created. Note that the right-eye image may be copied only to the B channel.

  In color anaglyph processing, the R channel of the left-eye image IL3 obtained by layer integration is copied (overwritten) to the R channel of the right-eye image IR3 obtained by the same layer integration. The right-eye image IR3 in which IL3 is copied to the R channel in this way becomes an anaglyph completed image that is the stereoscopic image IST.

  Note that the method for realizing the stereoscopic view is not limited to the anaglyph process as long as it is realized using at least the left-eye image and the right-eye image. For example, a special lens called a lenticular lens may be used to realize stereoscopic viewing so that only the image for the left eye enters the left eye and only the image for the right eye enters the right eye.

  In addition, a polarizing plate is disposed in front of the left-eye image and the right-eye image, and the polarizing direction is different between the polarizing plate placed in front of the left-eye image and the polarizing plate placed in front of the right-eye image. . Then, stereoscopic viewing may be realized by the viewer wearing spectacles in which a polarizing plate having a deflection direction corresponding thereto is attached to the lens portion.

  Also, the left-eye image and the right-eye image are displayed alternately, for example, with different frames. Then, the viewer wears glasses equipped with a shutter for the left eye (for example, a liquid crystal shutter) that opens in synchronization with the display of the image for the left eye and a shutter for the right eye that opens in synchronization with the display of the image for the right eye. Visualization may be realized.

4). Detailed Example Next, a detailed example of the stereoscopic viewing method of the present embodiment will be described with reference to the flowcharts of FIGS. Note that the stereoscopic viewing method of the present embodiment is not limited to this detailed example.

  First, the left eye image IL1 and the right eye image IR1 of the base object (OB1) are photographed (step S11). FIG. 7 shows an example of the base object left-eye image IL1, and FIG. 8 shows an example of the base object right-eye image IR1. 7 and 8, the base object is an elliptical object.

  Next, the left-eye image IL2 and the right-eye image IR2 of the floating object (OB2) are photographed (step S12). FIG. 9 shows an example of the left-eye image IL2 of the floating object, and FIG. 10 shows an example of the right-eye image IR2 of the floating object. 9 and 10, the floating object is an object such as gum.

  Next, correction processing for eliminating the perspective of the image on the reference plane is performed on the left-eye image IL1 and the right-eye image IR1 of the base object (step S13). That is, the correction process described with reference to FIG. Then, the image other than the base object image is trimmed from the image for left eye IL1 and the image for right eye IR1 after the correction process (step S14). That is, an image other than the base object image is cut out to leave only the base object image.

  Next, a shadow image is created with reference to the IL2 and IR2 images of the floating object after the correction process (step S15). That is, as shown in FIGS. 9 and 10, the shadow of the floating object is also photographed in the left-eye image IL2 and the right-eye image IR2 of the floating object. With reference to these photographed shadows, a shadow image (a shadow image showing a plurality of shadows) as shown in FIG. 11 is created.

  After such a shadow image is created, an image other than the floating object image is trimmed from the corrected left-eye image IL2 and right-eye image IR2 (step S16). That is, as shown in FIG. 12, images other than the floating object image (background image, shadow image, etc.) are cut out and only the floating object image is left.

  Next, the left eye image IL3 created by layer combining the base object left eye image IL1 and the floating object left eye image IL2, the base object right eye image IR1, and the floating object right eye image IR2 are layer combined. Based on the right-eye image IR3 created in this way, an anaglyph process is performed to create a stereoscopic image for confirmation (step S17). Then, referring to the confirmation stereoscopic image, the left-right image and the right-eye image are adjusted to adjust the left / right displacement (binocular parallax adjustment) to adjust the height and position in the stereoscopic view (step S18). ). The adjustment is repeated until the proper height and position are reached (step S19). Details of these adjustments will be described later.

  When the adjustment is completed, one shadow image on the base object among the created shadow images is inserted into each layer for the left eye and the right eye (step S20). Then, a left-right shift width (binocular parallax information) between the left-eye image and the right-eye image of the base object at the place where the shadow falls is acquired (step S21). Then, binocular parallax adjustment is performed by moving the left-eye and right-eye shadow images in the right direction or the left direction based on the obtained left-right shift width (step S22). At this time, the illumination direction is also taken into consideration.

  Next, a blurring process according to the height information of the floating object is performed on the shadow image (step S23). Then, the processes of steps S20 to S23 are performed on all the shadows on the base object (step S24). Details of generation and adjustment of these shadow images will be described later.

  Next, the background image is inserted into the background layer (step S25). FIG. 13 shows an image example in which a background image is inserted into the left-eye images IL1 and IL2. In FIG. 13, a gradient process is performed on the background image.

  Next, binocular parallax adjustment and blurring processing are performed on the shadow image on the background (step S26). For example, the shadow on the background is shifted leftward or rightward with the maximum shift width of the shadow on the base object. FIG. 14 shows an example of the left-eye image IL3 that has been subjected to stereoscopic height adjustment and shadow processing and has undergone layer synthesis. FIG. 15 illustrates that stereoscopic height adjustment and shadow processing have been completed, An example of the synthesized right-eye image IR3 is shown.

  Next, processing similar to step S17 is performed based on the left-eye image IL3 after layer synthesis in FIG. 14 and the right-eye image IR3 after layer synthesis in FIG. 15, and a stereoscopic image IST is created by anaglyph processing ( Step S27). FIG. 16 shows an example of the created stereoscopic image IST. The stereoscopic image IST in FIG. 16 can be created by copying (overwriting) the R (red) channel of the left-eye image IL3 in FIG. 14 to the R channel of the right-eye image IR3 in FIG.

  Finally, an image such as a logo or a character having no binocular parallax is synthesized with the stereoscopic image IST created in step S27 (step S28). FIG. 17 shows an example of a stereoscopic image IST after the synthesis of a logo or character image.

5). Adjustment Processing Next, the adjustment processing in steps S17 to S19 in FIG. 5 will be specifically described.

  FIG. 18A is a diagram showing a state when the base object OB1 is photographed with a camera. In FIG. 18A, since the base object OB1 is placed on the reference plane BS and taken by the camera, the reference plane BS has a height indicated by C1.

  On the other hand, when images such as logos and characters (hereinafter referred to as logo images) as shown in FIG. 17 are combined, the binocular parallax does not exist in the logo image (because the left eye and the right eye are the same image). ), During stereoscopic viewing, the logo image appears to be present at the height of the reference plane BS indicated by C1 in FIG. Therefore, there is a problem that the logo image can be seen at a position lower than the assumed position, and a natural and impactful logo image cannot be generated.

  In order to solve such a problem, binocular parallax adjustment processing is performed in steps S17 to S19 in FIG. For example, the binocular parallax adjustment is performed on the left-eye image IL1 and the right-eye image IR1 of the object OB1 to adjust the height of the reference plane for the object OB1 in stereoscopic view. Specifically, as shown by C2 in FIG. 18B, the binocular parallax is set such that the reference plane BS ′ is set above the reference plane BS at the time of shooting shown in C1 of FIG. Perform the adjustment process.

  In this way, the logo image shown in FIG. 17 appears to exist at the height of the reference plane BS ′ shown by C2 in FIG. An image can be generated.

  18A and 18B, the height adjustment of the reference plane of the base object OB1 has been described. However, the height adjustment of the reference plane of the floating object OB2 may be performed. In this case, binocular parallax adjustment is performed on the left-eye image IL2 and the right-eye image IR2, and the height of the object OB2 from the reference plane in the stereoscopic view is adjusted. In this way, the height at which the object OB2 floats can be adjusted, and a higher-quality stereoscopic image can be generated.

  In this case, the binocular parallax adjustment is performed by shifting the left-eye image IL (IL1, IL2) in either the left direction or the right direction, as shown in FIG. IR1, IR2) can be realized by shifting in the other direction different from one.

  For example, when performing adjustment to move the object OB (OB1, OB2) to a higher position (when performing adjustment to lower the reference plane), the left-eye image IL is shifted to the right and the right-eye image IR is moved to the left. Just shift it. On the other hand, when performing adjustment to move the object OB to a lower position (when performing adjustment to increase the reference plane), the left-eye image IL may be shifted to the left and the right-eye image IR may be shifted to the right.

  For example, in the conventional general stereoscopic method, even if such a horizontal shift width adjustment is performed, an appropriate binocular parallax adjustment cannot be realized. That is, in order to obtain an appropriate stereoscopic image by the conventional stereoscopic method, for example, adjustment of the vertical shift width is necessary, and binocular parallax adjustment becomes complicated.

  On the other hand, in the method of FIG. 4A, since the binocular parallax is determined by the shift width in the left-right direction, appropriate binocular parallax adjustment can be realized only by adjusting the shift width in the left-right direction. Therefore, as shown in FIG. 2A and FIG. 2B, when generating a stereoscopic image by combining images obtained by a plurality of times of camera photography, in stereoscopic viewing between the objects OB1 and OB2. There is an advantage that the height adjustment can be realized simply.

  An image having binocular parallax may be used as a logo image (logo, character image). Specifically, a left-eye logo image and a right-eye logo image are prepared. Then, the left-eye logo image and the first and second left-eye images IL1 and IL2 are synthesized (layer synthesis) to generate a third left-eye image IL3. The right-eye logo image and the first and second right-eye images The image images IR1 and IR2 are combined (layer combination) to generate a third right-eye image IR3. In this way, it is possible to generate a stereoscopic image that looks stereoscopically with respect to logos and characters.

6). Shadow Image When generating a stereoscopic image of the floating object OB2 as shown in FIG. 2B, it is desirable that the shadow SD of the object OB2 can be expressed realistically.

  However, when the object OB2 is photographed, the support rod of the object OB2 is also photographed, and this support rod may become an obstacle and part of the shadow SD image may be lost. Further, when the height of the reference plane is adjusted as shown in FIGS. 18A to 18C, the height relationship between the objects OB1 and OB2 in stereoscopic view also changes. Accordingly, there is a problem that the shadow SD image captured in FIG. 2B cannot be used as it is.

  Therefore, in steps S20 to S24 and S26 in FIG. 6, a shadow image is generated while performing various adjustment processes.

  For example, in the present embodiment, a left-eye shadow image ISL and a right-eye shadow image ISR for the shadow of the object OB2 are generated. Specifically, as shown in step S20 of FIG. 6, for example, a left-eye shadow image ISL and a right-eye shadow image ISR are generated by inserting a shadow image into each of the left-eye and right-eye layers.

  Then, the left-eye image IL3 as shown in FIG. 14 is generated by synthesizing (layer synthesis) the left-eye images IL1 and IL2 and the left-eye shadow image ISL. Further, the right-eye image IR3 as shown in FIG. 15 is generated by combining (layer combining) the right-eye images IR1 and IR2 and the right-eye shadow image ISR. Based on the left-eye image IL3 and the right-eye image IR3, as shown in FIGS. 16 and 17, a stereoscopic image IST that realistically represents the shadow of the floating object OB2 is generated.

  In this case, in order to express a higher quality shadow, it is desirable that the binocular parallax of the shadow image and the degree of blur according to the distance can be expressed realistically.

  For example, in FIG. 19A, the shadow SD1 of the floating object OB2-1 falls to the position indicated by D1, and the shadow SD2 of the object OB2-2 falls to the position indicated by D2. Therefore, it is desirable that the binocular parallax of the shadow SD1 is in accordance with the height of the place indicated by D1, and the binocular parallax of the shadow SD2 is in accordance with the height of the place indicated by D2. desirable. That is, if the binocular parallax for the shadows SD1 and SD2 is not appropriate, the shadows SD1 and SD2 appear to float at a position floating from the base object OB1 during stereoscopic viewing, resulting in unnatural stereoscopic viewing.

  Therefore, in steps S21 and S22 of FIG. 6, binocular parallax information of the object OB1 is acquired, and binocular parallax adjustment of the shadow image is performed based on the acquired binocular parallax information. For example, binocular parallax information at a place where the shadow of the object OB2 falls is acquired based on the left-eye image IL1 and the right-eye image IR1 of the object OB1. Based on the acquired binocular parallax information, binocular parallax adjustment is performed on the left-eye shadow image ISL and the right-eye shadow image ISR.

  For example, FIG. 20A is a diagram schematically showing an enlarged part of the left-eye image IL1 and the right-eye image IR1, and one square represents one pixel (one dot). In the image pattern of the place in FIG. 20A, the left and right shift widths (number of pixels, distance) of the images of IL1 and IR1 are DLR. Therefore, when a shadow falls on this place, as shown in FIG. 20B, the left-eye shadow image ISL is moved in the right direction by the shift width DL (number of pixels) corresponding to the shift width DLR in FIG. (Or move left). Further, the right-eye shadow image ISR is shifted leftward (or rightward) by the shift width DR (number of pixels) corresponding to the DLR. In this way, the left-eye shadow image ISL and the right-eye shadow image ISR are shifted by the shift widths DL and DR corresponding to the binocular parallax of IL1 and IR1 at this location, and IL1 and IR1 at this location Thus, the binocular parallax of ISL and the binocular parallax of ISL and ISR coincide with each other. Therefore, it is possible to prevent a situation in which a shadow appears at a position floating from the base object OB1 during stereoscopic viewing, and to realize stereoscopic viewing in which a more natural and realistic shadow is expressed.

  In step S22 in FIG. 6, the shift width (shift amount) of the shadow image for the left eye and the right eye is adjusted in consideration of the direction of illumination at the time of shooting. For example, when the illumination at the time of shooting is lighting from the diagonal left direction, the shadow image is shifted to the right by that amount.

  Further, in D1 and D2 in FIG. 19A, the heights of the floating objects OB2-1 and OB2-2 from the base object OB1 are different. In such a case, if the blur conditions of the shadows SD1 and SD2 are the same, the realism of the shadow is impaired.

  Therefore, in steps S23 and S26 of FIG. 6, a shadow blurring process according to the height of the floating object OB2 (OB2-1, OB2-2) is performed. For example, as shown in FIG. 19B, the left-eye shadow image ISL and the right-eye shadow image ISR are blurred (defocused) based on the height information of the floating object OB2. Specifically, the blur condition is reduced when the height of the floating object OB2 from the base object OB1 is low, and the blur condition is increased when the height is high. In this case, the degree of blur at the shadow boundary is adjusted using a blur filter or the like.

  In this way, as shown in FIGS. 16 and 17, it is possible to generate a stereoscopic image that realistically represents the degree of shadow blurring.

  In step S26 of FIG. 6, for the shadow on the background, for example, a shift width larger than the maximum shift width of the shadow on the base object OB1, for example, the right shadow image is shifted to the right, and the Set to shadow. By dropping such a shadow on the background, a background without a texture pattern appears to be at the back, and a more natural stereoscopic view can be realized.
