Description

  The present invention relates to a technique of a stereoscopic image manufacturing apparatus and a stereoscopic image manufacturing method for generating a stereoscopic image that can be viewed with the naked eye by a lenticular method or a parallax barrier method from images of a plurality of imaging bodies and providing it to a user.

  If a person can be photographed three-dimensionally and expressed three-dimensionally by the lenticular method or the parallax barrier method, it will be fun content for individuals for entertainment purposes, and will be a material for more accurate personal evaluation for security purposes. However, it has been difficult to place the necessary number of cameras at the correct position for that purpose.

  First, an apparatus for photographing an object three-dimensionally will be described. In an apparatus for photographing an object in three dimensions, in order to photograph an object from a plurality of directions, a plurality of cameras are arranged, a single camera is arranged at a plurality of positions, or in front of a single camera. It is necessary to move the object.

  First, a method for moving an object in front of one camera will be described. In order to photograph a subject from multiple directions with a single camera, generally when photographing an object so that it can be stereoscopically viewed with a lenticular sheet, when the subject is a single unit, A plurality of photographs are taken by rotating a little in front and taking a plurality of pictures. This photographing method is a rotation type. However, when a plurality of subjects are arranged in a horizontal row or when the subject group has a certain depth or more, the transition away from the center of rotation between each photo tends to be large. When a stereoscopic image is constructed, it tends to be very difficult to see. In order to avoid this, in such a case, it is desirable not to rotate the subject with respect to the camera but to take a picture while moving little by little in the horizontal direction so that the subject crosses the front of the camera. This method is a horizontal movement type.

  In the above description, the subject is moved little by little in front of one camera, but either method is the same even if the camera is moved with respect to the subject and taken. In addition, when a plurality of cameras are arranged in advance at the predetermined position and photographed at the same time, instead of moving the camera to shoot, not only a photo equivalent to the above case can be obtained, but also a person who changes every moment It is possible to capture a certain moment from a plurality of directions. As for the arrangement of the plurality of cameras, there are an arrangement corresponding to the rotation type and an arrangement corresponding to the horizontal movement type.

  First, the rotating camera arrangement will be described. In the rotary type, the subject is originally rotated in front of the camera. Therefore, if this is realized by arranging a plurality of cameras, the camera is arranged on an arc that is equidistant from the center of the subject as shown in FIG. Will be. Here, for the sake of simplicity, shooting is performed with four cameras from camera A (1701) to camera D (1704), and the shooting ranges of the respective cameras are set as shooting ranges a, b, c, and d. The surfaces on which the photographs obtained by these four cameras are taken are taken as photographing surfaces a ', b', c ', d', respectively.

  The images of the imaging planes a ′, b ′, c ′, and d ′ obtained in this way are combined so as to be stereoscopically viewed during viewing, as shown in FIG. 1801). As can be seen by comparing the two figures, the imaging planes a ′, b ′, c ′, d ′ in FIG. 17 are planes that intersect each other, whereas the imaging planes a ′, b ′, c ′ in FIG. , D ′ images are contained in a single plane. This means that the rotational arrangement does not provide accurate stereoscopic vision, and the viewer's brain only feels a stereoscopic effect approximately.

  For example, when the camera B (1702) and the camera C (1703) when photographing a person in FIG. 17 correspond to the viewer's left eye (1802) and right eye (1803) in FIG. Therefore, it can be seen that it is better that the imaging surface b ′ and the imaging surface c ′ in FIG. This means that camera B and camera C should not be far apart. This also indicates that the distance between the eyes in FIG. 18 is narrow, that is, it is better to set the camera so that it is viewed at some distance from the printed surface.

  Next, the horizontal movement type camera arrangement will be described. Since the horizontal movement type originally moves the subject in front of the camera in the horizontal direction, if this is realized by arranging a plurality of cameras, as shown in FIG. 19, the camera is in a straight line in front of the subject. It will be arrange | positioned at equal intervals.

  This arrangement is similar to the arrangement of the images shown in FIG. 18, which is why the horizontal movement arrangement is more convenient for providing stereoscopic viewing than the rotation arrangement. These techniques are also disclosed in Patent Document 1, for example.

Patent Document 2 discloses an invention relating to a 3D image object that produces a 3D effect by preparing a background image by 3D plate making in advance and synthesizing a two-dimensional portrait image with the background. When this person photograph image is a printed image by 3D plate making, an image object having a 3D effect can be acquired from the entire 3D image object.

  However, even in the case of the above-mentioned horizontal movement type arrangement, a particular inconvenient part can be seen from FIG. For example, pay attention to camera A in FIG. When the relationship between a normal lens and an imaging device (film or CCD) is applied, as shown in FIG. 20, the range necessary for generating a stereoscopic image of the subject is only between PR, as shown in FIG. In spite of this, an image is formed between the SRs on the imaging device. Actually, an image corresponding to SP is an unnecessary part that does not contribute to the generation of a stereoscopic image. As described above, there is a problem that a camera arranged at a position farther from the subject has a larger portion that is not necessary for generating a stereoscopic image, and the performance of the camera cannot be fully utilized.

  In addition, in order to obtain the plurality of captured images, it is necessary to prepare and arrange a plurality of cameras or to move one camera to an accurate position one after another. When a plurality of cameras are prepared, a considerable amount of money is required, and it is difficult for a general person who is not a trader who specializes in taking these images. Therefore, it was not possible to enjoy 3D images easily, such as having to shoot at a specialty store after all. On the other hand, when a single camera is moved and arranged one after another, advanced technology is required to accurately position the camera, and it is difficult for ordinary people to enjoy images easily. It was. When the subject is a person or the like, it moves slightly while moving the camera, and a captured image for generating a precise stereoscopic image cannot be obtained.

  Further, in Patent Document 2, it is said that an image object having a 3D effect can be obtained from the whole by making both a background image and a person image prepared in advance into a three-dimensional image. There is no disclosure about a method for easily obtaining a stereoscopic image. When acquiring an image in which both a person and a background can be viewed stereoscopically, the background can be stored in the apparatus in advance using the existing 3DCG technology. When a three-dimensional image is synthesized from a photograph taken in Step 1, it is necessary to photograph a subject from various directions to obtain a plurality of images. However, in order to acquire such a plurality of images, various problems have occurred as described above. In Patent Document 2, the problem in this respect has not yet been solved and still remains.

  In order to solve the above-described problem, the first invention includes a plurality of lenses arranged in parallel and a plurality of imaging devices arranged in parallel corresponding to each lens.

  Embodiment 1

  (Concept of Embodiment 1) The stereoscopic image manufacturing apparatus of the present embodiment is composed of a plurality of lenses and a plurality of imaging devices, and these are arranged independently to project one subject area substantially at the center. Can do. In the normal camera shown in FIGS. 17 to 20, as shown in FIG. 19, one lens and one imaging device such as a film are the normal lines at the optical axes of all the lenses and the center of the imaging device corresponding thereto. The lens and the imaging device are arranged so that. However, in the present embodiment, the plurality of lenses and the plurality of imaging devices do not necessarily match the optical axis of the lens and the normal line at the center of the imaging device, and are common to all imaging devices via the corresponding lenses. Are arranged so that their subject areas are substantially centered. That is, in the stereoscopic image manufacturing apparatus according to the present embodiment, as shown in FIG. 21, it is possible to take images centered on PR, which is an area necessary for generating a stereoscopic image in FIG. Become.

  (Configuration of Embodiment 1) FIG. 1 is a plan view showing the configuration of the stereoscopic image manufacturing apparatus of this embodiment. As shown in FIG. 1, the stereoscopic image manufacturing apparatus (0100) of the present embodiment includes a “plurality of lenses” (0101) and a “plurality of imaging devices” (0102).

  (Description of Configuration of Embodiment 1) A “stereoscopic image manufacturing apparatus” (0100) includes “plural lenses” (0101) and “plural imaging devices” (0102), and generates a stereoscopic image. A plurality of necessary captured images can be taken. A captured image is an image captured by an imaging device, and includes a still image and a moving image. A stereoscopic image is a composite of a plurality of captured images so that stereoscopic viewing is possible by a lenticular method or a parallax barrier method. Note that the stereoscopic image is also referred to as a 3D image. The same applies to the following embodiments. In addition to these configurations, the stereoscopic image manufacturing apparatus has a necessary configuration as appropriate when it has the functions of the second to eighth embodiments.

  The “plural lenses” (0101) are arranged in parallel as shown in FIG. “A plurality of lenses arranged in parallel” means that a plurality of lenses are arranged so that the optical axes of the lenses are all substantially parallel. In addition, it is desirable that all the lenses be arranged so that the optical axes are strictly parallel, but depending on conditions such as the size of the arrangement space, the optical axes should be slightly inclined toward the subject. Etc. are allowed. Moreover, as shown in FIG. 1, the term “parallel” is a concept including not only a state in which lenses are arranged horizontally in a straight line but also a state in which lenses are arranged in a curved line. The plurality of lenses in the present embodiment are arranged linearly as shown in FIG.

  As shown in FIG. 1, “a plurality of imaging devices” (0102) are arranged in parallel corresponding to each lens. “A plurality of imaging devices arranged in parallel” means that a plurality of imaging devices are arranged so that the normals of the planes of the imaging devices are all substantially parallel. As with the lens described above, it is desirable to arrange the imaging device so that the normals are strictly parallel to each other. However, depending on the conditions such as the size of the arrangement space, the normal line may be used. Is allowed to be slightly tilted toward the subject. In addition, as shown in FIG. 1, the term “parallel” is a concept including not only a state in which the imaging devices are horizontally arranged in a straight line but also a state in which the imaging devices are arranged in a curved line. The plurality of imaging devices in the present embodiment are arranged linearly as shown in FIG.

  Since the plurality of imaging devices are arranged in a one-to-one correspondence with the plurality of lenses, the number of lenses and the number of imaging devices are the same. Although the number of lenses and imaging devices is 5 in FIG. 1, in order to obtain a plurality of images that can be actually viewed with the naked eye, more pairs of lenses and imaging devices may be provided. good. As an example, the combination of the lens and the imaging device can be 10 to 20 sets. The imaging device corresponds to a film when using an analog camera, and corresponds to an imaging device such as a CCD when using a digital camera. The image acquired by the imaging device may be a still image or a moving image.

  The plurality of imaging devices (0102) are arranged at a position where a common subject area (0103) is projected to substantially the center through the corresponding lens (0101) in all the imaging devices. The “subject area” (0103) is an area in a range where the subject (0104) is photographed on the photographing surface (0106). The subject (0104) is not limited to a single object, and may be a plurality of objects. When the subject is composed of a plurality of objects, the objects may exist at different depths or may overlap in the subject area. Further, assuming that a range to be imaged by a plurality of imaging devices on the imaging surface (0106) is an imaging area (0105), each imaging device (0102) so that the subject area (0103) is substantially at the center of the imaging area (0105). In other words, can be arranged. When the subject exists in the entire shooting area, the shooting area (0105) and the subject area (0103) on the shooting surface (0106) are substantially the same.

  (Specific Example of Embodiment 1) As shown in FIG. 2, when one area photographed through one lens (0101a) corresponding to one imaging device (0102a) is defined as an imaging area (0105a), a subject area One lens (0101a) is arranged so that (0103) is substantially in the center of the imaging region, and one imaging device (0102a) corresponding to the lens is arranged. When a plurality of imaging devices (0102) corresponding to all the plurality of lenses (0101) arranged in parallel are arranged in parallel while maintaining this relationship, as shown in FIG. The imaging device (0102) can be arranged such that one subject area (0103) common to the approximate center of the imaging area (0105) in FIG.

  It should be noted that by using an imaging device having a different size depending on the position where the imaging device (0102) is arranged, it is possible to make all the shooting areas have the same size. If the subject area is included in the area, the difference in the size of the photographing area for each imaging device is not a problem in the synthesis of the stereoscopic image of the subject.

  By arranging the lens and the imaging device in this way, an image necessary for generating a stereoscopic image from various positions can be taken without unnecessarily enlarging the imaging device. The projection method with the arrangement as shown in FIG. 2 is called oblique projection. The shift amount of the imaging device for causing oblique projection varies depending on the arrangement positions of the lens and the imaging device, and is proportional to the distance between the lens optical axis and the center of the imaging region. This will be described in more detail with reference to FIG.

  As shown in FIG. 3, the lens (0101) and the imaging device (0102) are all arranged parallel to the imaging surface (0106). The intersection of the straight line L indicating the optical axis of the lens passing through the center A of the lens (0101) and the photographing surface is O, and the intersection of the surface where the imaging device is present is O ′. An imaging device is arranged between P ′ and R ′, and the center between P ′ and R ′ is Q ′. At this time, the imaging region is between PR, and the triangle AOQ and the triangle AO'Q 'are similar if the center Q between PR is taken. Accordingly, the imaging device is appropriately shifted by shifting in proportion to the distance (between OQ) between the lens optical axis (straight line L) and the center of the imaging region (0105) (shift between O ′ and Q ′). Can be placed at any position. The imaging region (0105) changes according to the distance AO ′ between the lens (0101) and the imaging device (0102) and the distance AO between the lens (0101) and the imaging surface (0106). . As described above, the imaging device can be arranged such that only the region where the subject is projected is projected onto the imaging device among the regions projected via the lens by oblique projection.

  Both the lens and the imaging device may be movable, or only one may be movable and the other may be fixed. In addition, for example, when the stereoscopic image manufacturing apparatus according to the present embodiment is used for a photo booth (registered trademark) or an ID photo, the photographing area and the subject area are limited by a casing or the like. Both imaging devices may be fixed.

  When the arrangement position of the lens and the imaging device is movable, for example, the lens or the like can be arranged by placing each lens and the imaging device on separate actuators and arranging the actuators at appropriate positions. . The actuator can be easily placed at a specific position by controlling the voltage and magnetic field with a computer or the like. In addition, it is desirable to control the arrangement of the lens and the imaging device so that the lens and the imaging device are arranged at an appropriate position according to the subject so as to achieve pan focus or auto focus.

  (Effect of Embodiment 1) According to the stereoscopic image manufacturing apparatus of the present embodiment having the above-described configuration, only the area where the subject is projected is projected onto the imaging device among the areas projected via the lens. Thus, an imaging device can be arranged, and an imaging device on which a portion unnecessary for generating a stereoscopic image is projected can be omitted. For this reason, it is possible to make full use of the performance of the imaging device, and even when a low-cost lens and imaging device are used, it is possible to generate a stereoscopic image similar to the conventional technology. Therefore, the entire stereoscopic image manufacturing apparatus can be manufactured at a low cost.

  << Embodiment 2 >>

  (Outline of Embodiment 2) In the three-dimensional image manufacturing apparatus of Embodiment 1, when the distance from the lens to the subject is short, the imaging device far from the center needs to be largely shifted left and right. For example, as shown in FIG. 4, when there is a limit to the shift amount of the imaging device, imaging on the imaging surface (0406) projected onto the corresponding imaging device (0402a) via the end lens (0401a). In some cases, it is difficult to project the subject area (0403) on the approximate center of the area (0403a). In the stereoscopic image manufacturing apparatus of the present embodiment, a plurality of lenses and a plurality of imaging devices are arranged in a curved shape so that the subject area is projected substantially at the center of the imaging area even in such a case. .

  (Configuration of Embodiment 2) FIG. 5 is a plan view showing the configuration of the stereoscopic image manufacturing apparatus (0500) in this embodiment. The configuration of the stereoscopic image manufacturing apparatus (0500) in this embodiment is the same as that of the stereoscopic image manufacturing apparatus in Embodiment 1, but a plurality of imaging devices (0502) arranged corresponding to the plurality of lenses (0501). These are arranged in parallel in a curved shape.

  (Description of Configuration of Second Embodiment) The lens (0501) and the imaging device (0502) in this embodiment are arranged in parallel correspondingly as in the first embodiment, but as shown in FIG. The imaging devices are arranged not in the same straight line but in a curved line shape. Although not shown, the imaging devices may be arranged in a straight line and only the lens may be arranged in a curved line, or both may be arranged in a curved line. Note that the arrangement of the lens or the imaging device may have a necessary inclination in the direction of the subject in order to adjust the focus.

  (Specific Example of Embodiment 2) A specific example of the stereoscopic image manufacturing apparatus according to this embodiment will be described with reference to FIG. In FIG. 5, a plurality of lenses (0501) are arranged in a straight line, and only the imaging device (0502) is arranged in a substantially staircase shape. Thus, by bringing the arrangement position of the imaging device close to the lens, for example, in the imaging device (0502a) at the left end, the imaging region (0505a) is wider than in the case illustrated in FIG. (0505a) can be projected to the approximate center.

  The plurality of lenses and the plurality of imaging devices in the present embodiment are curved as necessary by moving the imaging device and the lenses from the state in which the lens and the imaging device described in the first embodiment are linearly arranged. It is good also as arranging in a shape. For example, as described in the first embodiment, when the lens and the imaging device are arranged in a straight line and the subject area (0403) is not substantially the center of the imaging area (0405a) as shown in FIG. Alternatively, the lens or the like may be moved by an actuator or the like and arranged in a curved shape.

  In the stereoscopic image manufacturing apparatus according to the present embodiment, when the subject area is limited such as a person ID photo specialized for single-person photography, the lens and the imaging device are arranged in a curved shape and fixed at an optimal position. Can do.

  (Effect of Embodiment 2) According to the stereoscopic image manufacturing apparatus of this embodiment having the above-described configuration, the moving range of the imaging device in the left-right direction is limited, and the lens and the imaging device are arranged linearly. In some cases, even if the subject area is not the approximate center of the shooting area, the shooting area is adjusted by changing the arrangement shape of a specific lens or imaging device, and the subject area is set to the approximate center of the shooting area. Can do. For this reason, a stereoscopic image manufacturing apparatus can be provided even in a space where movement of the imaging device and the lens in the left-right direction is limited.

  << Embodiment 3 >>

  (Outline of Embodiment 3) A plurality of lenses and a plurality of imaging devices in this embodiment can be adjusted in their arrangement positions depending on where the subject area is determined. For example, as illustrated in FIG. 6, an outline of an adjustment unit that adjusts the arrangement position of a lens or an imaging device is illustrated. The adjustment unit (0603) illustrated in FIG. 6 is an example configured with a linear actuator. As shown in FIG. 6 (1), a rail (0601) whose magnetic poles can be changed by a coil and a magnet (0602) having N and S magnetic poles spaced apart from each other on the rail (0601) are prepared. . A lens or an imaging device (0604) is placed on the magnet. In the state of FIG. 6 (1), the magnet is in a balanced state and is stopped. When a part of the magnetic pole of the rail is changed from this state as shown in FIG. 6 (2), a repulsive force and an attractive force are generated in the magnet (0601), and the magnet moves in the direction indicated by the arrow. Stop in the state shown in. In this way, a plurality of magnets on which a lens is placed are arranged on one rail, and the lens can be arranged at an appropriate position by adjusting the magnetic pole generated on the rail. Similarly, by arranging a plurality of magnets on which an imaging device is mounted on one rail different from the above and adjusting magnetic poles generated on the rail, the imaging device can be arranged at an appropriate position. The subject area can also be adjusted by adjusting the distance between the rails on which the lens and the imaging device are arranged.

  (Configuration of Embodiment 3) FIG. 7 is a plan view showing the configuration of the stereoscopic image manufacturing apparatus of this embodiment. As shown in FIG. 7, the stereoscopic image manufacturing apparatus (0700) of the present embodiment includes a “plurality of lenses” (0701) and a “plurality of imaging devices” (0702). Part "(0703). Since the steps other than the “adjustment unit” (0703) have already been described in the first embodiment, description thereof will be omitted.

  (Description of Configuration of Embodiment 3) “Adjustment unit” (0703) is a relative arrangement of a plurality of lenses (0701) and a plurality of imaging devices (0702) depending on where one subject region is defined. Configured to adjust. The adjustment unit (0703) may be configured by a linear actuator as shown in FIG. 6, or may be configured by a piezoelectric actuator or the like. In FIG. 7, the adjustment unit (0703) is provided so that both the lens (0701) and the imaging device (0702) can be adjusted. However, the adjustment may be made by arranging only the lens or only the imaging device in the adjustment unit. .

  As already described in the first embodiment with reference to FIG. 3, when the shift amount of the imaging device with respect to the lens or the distance between the lens and the imaging device changes, the position and size of the subject region change. This will be described in detail in the following specific example with reference to FIG.

  (Specific Example of Embodiment 3) FIG. 8A shows the lens (0701) and the imaging device (0702) so that the subject area (0802) on the imaging surface (0804) is substantially the center of the imaging area (0803). This is the case. FIGS. 8B and 8C show the case where the distance from the surface on which the plurality of lenses (0701) are arranged to the subject (0801) is shorter than that in FIG. 8A. The subject (0801) arranged in FIG. 8A is moved closer to the surface on which the plurality of lenses (0701) are arranged, and moved to the position shown by the broken line in FIG. 8A (the subject position shown in 0801a). And In this case, the subject area (0802a) projected via the corresponding lens (0701) on the imaging device (0702) close to both the left and right ends is projected to be biased to the left and right of the imaging area (0803a). This deviation amount becomes larger as the imaging device is farther from the position of the subject.

  Therefore, as shown in FIG. 8B, by adjusting the position of one or both of the plurality of lenses (0701) and the plurality of imaging devices (0702), the subject area (0802a) is changed to the imaging area (0803a). ). In FIG. 8B, by horizontally moving the positions of the left and right lenses (0701) away from the subject (0801b) toward the center, the subject region (0802b) in the corresponding imaging device (0702) becomes the shooting region (0802b). It is adjusted so that it is projected on the approximate center of 0803b).

  In FIG. 8C, when the subject (0801c) moves to the position indicated by the broken line in FIG. 8A, a surface (0805) on which a plurality of lenses are arranged and a plurality of imaging devices are arranged. The subject area (0802c) in the plurality of imaging devices is adjusted so as to be projected on the approximate center of the imaging area (0803c) by bringing the surface (0806) being close to each other.

  Further, the adjustment unit can adjust the distance from the subject by moving the stereoscopic image manufacturing apparatus back and forth.

  Embodiment 6

  (Concept of Embodiment 6) The stereoscopic image manufacturing apparatus according to this embodiment uses the lenticular method or the parallax barrier method for images picked up by a plurality of image pickup devices according to any one of Embodiments 1 to 5. It has a synthesizing unit that synthesizes it so that it can be stereoscopically viewed. For this reason, it is possible to perform from subject imaging to stereoscopic image synthesis with one apparatus.

  (Configuration of Embodiment 6) FIG. 11 is a schematic diagram showing a stereoscopic image manufacturing apparatus of this embodiment. As shown in FIG. 11, the stereoscopic image manufacturing apparatus (1100) of this embodiment includes a “plural lenses” (1101), a “plural imaging devices” (1102), and an “adjustment unit” (1103). And a “combining unit” (1104). Since the components other than the “synthesis unit” (1104) have already been described in the first to fifth embodiments, the description thereof will be omitted.

  (Description of Configuration of Embodiment 6) The “synthesizing unit” (1104) synthesizes images picked up by a plurality of image pickup devices (1102) so as to enable autostereoscopic viewing by a lenticular method or a parallax barrier method. It is configured as follows. In the case where the imaging device is a CCD, a captured image can be acquired with digital data. Therefore, the combining unit can be configured by a computer or the like. In the case of using a computer, a CPU (Central Processing Unit), a HDD (Hard Disk Drive), a RAM (Random Access Memory), a ROM (Read Only Memory), a program for creating a stereoscopic image stored in the HDD, etc. The composition unit is configured. When a plurality of digital data is acquired, the combining unit starts up a program stored in the HDD and performs processing to create a combined image that can be viewed with the naked eye.

  In the synthesizing unit, the convex shape (1202) of the lenticular type lenticular sheet (1201) shown in FIG. 12 (a) or the slit (1204) of the parallax barrier type parallax barrier sheet (1203) shown in FIG. 12 (b). A plurality of captured images can be processed into strips according to the interval of the images, arranged at appropriate positions, and a stereoscopically viewable image arranged on the screen (1205) can be synthesized and generated. When an image synthesized by the synthesis unit is output and a lenticular sheet or a parallax barrier sheet is superimposed on the image, the subject imaged by the imaging device can be stereoscopically viewed.

  (Specific Example of Embodiment 6) In the combining unit (1104), position correction or position correction is performed on each image so that a plurality of images obtained by imaging an object such as a person with the imaging device (1102) can be correctly combined into a three-dimensional image. It is necessary to perform distortion correction. Possible correction items include misalignment when assembling the stereoscopic image manufacturing apparatus, misalignment due to arrangement errors of the plurality of lenses (1101) and the plurality of imaging devices (1102), distortion due to lens aberration, and color misregistration. is there. By adjusting the relative positional relationship between the lens and the imaging device in the adjustment unit (1103), these shifts can be corrected in the synthesis unit. This mechanism is described below.

  In the correction, the operator can confirm the shift by acquiring a plurality of images at any time during operation of the stereoscopic image manufacturing apparatus (1100), and adjust the arrangement of the lens (1101) and the imaging device (1102) each time. Although it is good, it is desirable that the data on what image deviation occurs in all possible relative positional relations of the necessary lens (1101) and imaging device (1102) when the stereoscopic image manufacturing apparatus is installed. May be collected in advance and stored in the stereoscopic image manufacturing apparatus as correction data for each apparatus. In this case, the stereoscopic image manufacturing apparatus is provided with a storage area for storing correction data. In this way, if correction data is stored in advance, the synthesizer (1104) can calculate a correction amount from the difference between the correction data and the acquired captured image, and correct the generated deviation as appropriate. It is more desirable to periodically update the correction data stored in the storage area.

  Correction data is collected by the following method. First, as shown in FIG. 13, a white plate (1302) in which black circles are regularly arranged in a square lattice pattern is prepared and vertically set. It is assumed that the size of the plate is almost the same as the assumed imaging area. For example, if the shooting area is set to cover the range from one to three persons and from the chest to the head, the size of the board is almost the same as the three persons from the chest to the head. There is a need. The stereoscopic image manufacturing apparatus (1301) is arranged facing the above plate, and in this state, the imaging region is imaged by the imaging device. In the state shown in FIG. 13, since the subject is not arranged, it is assumed that the subject region has the same size as the plate set as the photographing region.

  Then, after arranging a plurality of lenses and a plurality of imaging devices in a position where the shooting area is assumed to be a range where one person is shot, three shooting areas are sequentially arranged at a certain interval. Is moved to a position where it is assumed that the person will be photographed. At this time, the stereoscopic image manufacturing apparatus moves in a direction away from the subject sequentially. The imaging device captures a white plate at each position and acquires an image. In this way, if photographing is repeated at all assumed positions, information that can be corrected for all the above-described shifts and distortions is obtained. Further, even when the lens and the imaging device as shown in the second embodiment are arranged in a curved line, the shooting area and the subject area are adjusted so that one person is photographed substantially at the center, After the lens and the imaging device are arranged at an appropriate position and the apparatus is assembled, correction data can be obtained by photographing the distance between the assumed person and the stereoscopic image manufacturing apparatus away from the white plate. The combining unit can perform appropriate position correction and distortion correction at the time of combining the stereoscopic image by using the correction data stored in advance as described above.

  When performing actual photographing, first, the position of the plurality of lenses (1101) and the plurality of imaging devices (1102) illustrated in FIG. 11 is adjusted by the adjustment unit (1103), and imaging is performed at the arranged positions. The device (1102) acquires a plurality of captured images of the subject. When the imaging device (1102) is a CCD or the like, the acquired captured image is digital data, and the synthesis unit performs processing so that the image data can be viewed stereoscopically by a lenticular method or a parallax barrier method. A stereoscopic image is generated. At this time, the combining unit performs correction of displacement and distortion that could not be corrected by the arrangement adjustment performed by the adjusting unit at the time of shooting using the correction data described above, and a plurality of combined images can obtain a stereoscopic effect. Are combined into a single 3D image.

  A method for synthesizing a stereoscopic image can be created according to a general 3DCG method. This synthesized image is output to inkjet paper etc. with an inkjet printer, etc., and a lenticular sheet or parallax barrier sheet is superimposed and pasted on the appropriate position to create a 3D image that can be viewed with the naked eye. can do.

  (Effect of Embodiment 6) In the stereoscopic image manufacturing apparatus according to the present embodiment, an image that allows the captured image acquired by the imaging device to be stereoscopically viewed by the synthesizing unit using the lenticular method or the parallax barrier method. Can be synthesized. Accordingly, since one device can perform imaging from a subject to synthesis of a stereoscopic image, a stereoscopic image can be easily generated from the subject.

  In addition, by adjusting the distance between the subject and the stereoscopic image manufacturing apparatus by the adjustment unit, a positional shift at the time of assembling the stereoscopic image manufacturing apparatus, a positional shift due to an arrangement error of a plurality of lenses and a plurality of imaging devices, and an aberration of the lens It is also possible to correct distortion and color misregistration caused by. Therefore, it is possible to acquire a plurality of favorable images for generating a stereoscopic image.

  << Embodiment 7 >>

  (Outline of Embodiment 7) In the stereoscopic image manufacturing apparatus of Embodiment 6, since a subject such as a person is photographed by a plurality of imaging devices, an image representing the subject in three dimensions can be synthesized. However, it is difficult to three-dimensionally combine the background of the imaged subject. Therefore, in the stereoscopic image manufacturing apparatus according to the present embodiment, a plurality of captured images are combined so that the subject can be stereoscopically viewed, and then the combined image of the subject is overlaid on previously stored 3D data. Thus, it is possible to generate an image that allows the entire synthesized image to be stereoscopically viewed.

As shown in FIG. 14, the stereoscopic image manufacturing apparatus (1400) of this embodiment includes a “plural lenses” (1401), a “plural imaging devices” (1402), and an “adjustment unit” (1403). The “combining unit” (1404) further includes a “storage unit” (1405) and a “3D data synthesizing unit” (1406). Since the steps other than “storage unit” (1405) and “3D data composition unit” (1406) have been described in the first to sixth embodiments, description thereof will be omitted.

  (Description of Configuration of Embodiment 7) The “storage unit” (1405) has a function of storing 3D data. The 3D data is digital data such as a still image or a moving image, and is data that is synthesized in advance so that it can be stereoscopically viewed by a lenticular method or a parallax barrier method. The 3D data includes, for example, a scenery such as a sightseeing spot or a street corner, a portrait of a celebrity, an animated character, a plant, an animal, etc., synthesized in a stereoscopic view. The storage means has a storage area such as an HDD and stores these 3D data.

  The “3D data synthesizing unit” (1406) has a function of synthesizing the synthesized image and the 3D data. A composite image is an image obtained by combining captured images of a subject acquired by a plurality of imaging devices so as to enable stereoscopic viewing. The 3D data synthesizing unit can further synthesize the synthesized image and the 3D data stored in the storage area of the storage unit (1405). Therefore, the 3D data synthesizing unit can synthesize an image in which both the subject and the background image can be stereoscopically viewed.

  (Specific Example of Embodiment 7) A specific example of the stereoscopic image manufacturing apparatus according to this embodiment will be described with reference to FIG. In the plurality of lenses and the plurality of imaging devices according to the present embodiment, first, captured images of a plurality of subjects are acquired by the method described in the first to sixth embodiments. At this time, if a blue screen or a green screen is placed on the background of the subject to be imaged and the subject background is a single color, the subject is subjected to image processing such as chroma key method at the synthesis unit. Only the image can be taken out.

  When a plurality of captured images are acquired in this way, the synthesis unit synthesizes the subject imaged in the subject area so that it can be stereoscopically viewed by the lenticular method or the parallax barrier method, and the result is shown in FIG. A composite image of the photographed subject as shown is acquired. When the combined image of the subject is acquired, the 3D data combining unit combines the 3D data stored in the storage unit as shown in FIG. 15B with the combined image. At this time, as described above, if an image of only the subject can be taken out, it is combined with 3D data and as if a person exists in the space of the stereoscopic image as shown in FIG. Can show. In addition, if the user can arbitrarily select 3D data to be synthesized, the user can enjoy his / her 3D image appearing in various scenes. In addition to arranging the subject in front of the 3D data serving as the background, it is also possible to synthesize the composite image of the subject and the 3D data so that the stereoscopic effect and depth of the subject are in appropriate positions.

  Furthermore, if images captured by the imaging device are continuously captured, and the stereoscopic image of the subject is a moving image, and the 3D data is also a moving image, a moving image in which the subject appears in the video is generated. It is also possible.

  (Effect of Embodiment 7) According to the stereoscopic image manufacturing apparatus of the present embodiment having the above-described configuration, it is possible to synthesize a stereoscopically viewable image of both the subject and the background image. It is possible to easily generate a stereoscopic image as if it exists in the image. Therefore, in the stereoscopic image manufacturing apparatus according to the present embodiment, the user can enjoy more stereoscopic images.

  (Outline of Embodiment 8) The 3D photo manufacturing apparatus of this embodiment can provide a user with a sheet on which a 3D image is printed in a simple photo-taking apparatus such as a photo booth (registered trademark) or ID photo.

  (Configuration of Embodiment 8) FIG. 16 is a schematic diagram showing a 3D photo production apparatus of this embodiment. As shown in FIG. 16, the 3D photo production apparatus (1600) of this embodiment includes a “photographing box” (1601), a “3D image photographing unit” (1602), and a “print output unit” (1603). Have

  (Description of Configuration of Embodiment 8) The “shooting box” (1601) is configured so that a person can enter as a subject. In the shooting box shown in FIG. 16, a space is provided so that about one to three people can enter as subjects. The photographing box may be appropriately provided with a chair or the like, and the entrance may be partitioned by a light shielding curtain or the like so that external light does not enter the photographing box.

  The “3D image photographing unit” (1602) is configured to photograph a person who enters the photographing box as a 3D image. A 3D image refers to an image that can be stereoscopically viewed by a lenticular method or a parallax barrier method. The 3D image photographing unit includes a plurality of lenses (1604) and a plurality of imaging devices (1605), and synthesizes the photographed images into a 3D image. The 3D image capturing unit can be configured by, for example, the stereoscopic image manufacturing apparatus described in the first to seventh embodiments. When a stereoscopic image manufacturing apparatus is used, as shown in FIG. 16, in addition to a plurality of lenses (1604) and a plurality of imaging devices (1605), a 3D image photographing unit is configured by including an adjustment unit and a synthesis unit. To do.

  The “print output unit” (1603) is configured to print out the 3D image captured by the 3D image capturing unit. The print output unit is configured by an inkjet printer or the like. By outputting the 3D image by the print output unit, it is possible to perform from 3D image shooting to print output by one 3D photo production apparatus.

  (Specific Example of Embodiment 8) As described above, the 3D photo production apparatus according to this embodiment can output a 3D image that can be stereoscopically viewed with one apparatus. For this reason, for example, it can be used as a device for ID photographs or as a device instead of a so-called Purikura (registered trademark) in an amusement facility or the like. In the 3D photo production apparatus (1600) shown in FIG. 16, a space for one to three users is provided in the photographing box (1601). The 3D image acquisition unit (1602) uses the stereoscopic image manufacturing apparatus according to any one of the first to seventh embodiments. The plurality of lenses (1604) and the plurality of imaging devices (1605) of the stereoscopic image manufacturing apparatus are arranged at positions facing the subject in the shooting box. In addition, since the captured image acquired by the combining unit is combined with 3D data by a chroma key method or the like, it is desirable that the background of the subject is plain without a pattern. When image processing such as a chroma key method is performed, in general, (1) it is difficult to shoot so that the screen has a completely single color, and (2) the color of the subject is the screen. In the case of the same color, there is a problem that the part appears as if there is a hole. In order to solve these problems, it is necessary to obtain a background with as high a color purity as possible. For this reason, it is desirable to use a high-luminance blue light emitting LED or the like as the background of the subject so that the screen itself emits light in a single color.

  The 3D image acquisition unit (1602) is provided with a button for starting shooting, and the user presses this button to send an instruction to start shooting to the stereoscopic image manufacturing apparatus constituting the 3D image acquisition unit. Then, the stereoscopic image manufacturing apparatus acquires a plurality of user images with a plurality of imaging devices after performing the distance adjustment between the subject and the lens or the imaging device, the position of the subject area in the imaging region, the focus adjustment of the subject, and the like. For example, when the imaging device is a CCD or the like, the acquired image is digital data, and the combining unit synthesizes the image data so that it can be stereoscopically viewed by the lenticular method or the parallax barrier method. When the combining unit includes the storage unit and the 3D data combining unit described in the seventh embodiment, the combined image and the 3D data may be combined to further combine a stereoscopically viewable image. Note that the instruction to start shooting displays a button for starting shooting on a display (1607) or the like provided in the 3D photo manufacturing apparatus, and the button displayed on the display is pressed on the touch panel to obtain a 3D image acquisition unit. It may be transmitted to.

  The synthesized image is printed and output by an inkjet printer or the like constituting the print output unit (1603). The output image is further pasted with a lenticular sheet or a parallax barrier sheet superimposed at an appropriate position. By using the back side of a printing sheet such as paper or plastic film to be printed as an adhesive surface, a stereoscopically viewable image can be directly pasted on another mount for viewing. Also, it is desirable to use a translucent film or the like for the release paper covering the adhesive surface on the back side. In this case, the completed stereoscopically visible image can be viewed as it is by supplying light from the back of the print sheet without sticking it to another mount.

  In addition, it is desirable to use a transparent liquid paste or the like for attaching the lenticular sheet or the like to the print sheet. When the stereoscopic image manufacturing apparatus is configured to perform these processes in this way, the user can easily enjoy his / her own photograph as a stereoscopic image, and when using it as an ID photo, Since individual features can be captured more in the manufactured stereoscopic image, it can be used for personal authentication.

  (Effect of Embodiment 8) In the 3D photo production apparatus according to this embodiment, the acquisition of captured images from a plurality of directions of the subject, the synthesis of the acquired captured images, and the output of the combined image are performed with one apparatus. Since this can be done, the user can easily produce his or her 3D image. Therefore, when the 3D photo production apparatus of the present embodiment is installed in an amusement facility or the like, it is possible to provide a highly entertaining Purikura (registered trademark). In addition, when the 3D photo production apparatus of this embodiment is used for person authentication, a person can be displayed three-dimensionally, and the personal characteristics can be captured more in the same operation as a conventional ID photo apparatus. ID photo can be provided.
