  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 shows a system 50 according to the present embodiment. The system 50 includes a display device 10, an imaging device 20, and ornamental glasses 30. The display device 10 is a device that displays an image received from the imaging device 20. For example, the display device 10 may be a television receiver or a PC monitor. Accordingly, the system 50 can easily provide a three-dimensional image to the viewer by using the display device 10 and the viewing glasses 30 for the image captured by the imaging device 20.

  The imaging device 20 outputs the captured image to the external display device 10. For example, the imaging device 20 may be a digital camera, a digital single-lens reflex camera, a video camera, or the like. In addition, the imaging device 20 transmits a synchronization signal with the display device 10 to the ornamental glasses 30 by wire or wirelessly. Thereby, the imaging device 20 can link the display device 10 and the ornamental glasses 30.

  The viewing glasses 30 are worn by a viewer to view an image displayed from the display device 10. The ornamental spectacles 30 are provided with shutters using liquid crystal or the like for each lens. The ornamental glasses 30 alternately open and close the shutters according to the synchronization signal transmitted from the imaging device 20. Thereby, the spectacles 30 for viewing can provide an image for the right eye displayed on the display device 10 to the right eye of the viewer, and an image for the left eye to the left eye of the viewer.

  FIG. 2 shows a configuration of the imaging apparatus 20 according to the present embodiment. The imaging device 20 generates a display image from the captured two-dimensional image and outputs it to the external display device 10. More specifically, the imaging device 20 generates an image to be output to the viewer's right eye and an image to be output to the viewer's left eye based on the given two-dimensional image. Is displayed on the display device 10. The given two-dimensional image may be a still image or a moving image including a plurality of still images that are temporally continuous. Further, the imaging device 20 can synchronously control the ornamental glasses 30 worn by the user so as to block the field of view of the other eye while an image for one of the right eye and the left eye is displayed on the display device 10. it can.

  The imaging device 20 includes an imaging unit 200, a generation unit 201, an image output unit 202, a synchronization control unit 203, an interface unit 204, an adapter 210, and a storage unit 205. The imaging unit 200 captures and stores an image. The imaging unit 200 transmits an image to the generation unit 201 when displaying the captured image.

  The generation unit 201 generates an image for the right eye and an image for the left eye in which the captured image is shifted relative to the left and right. For example, the generation unit 201 generates a left image and a right image in which the same two-dimensional image is shifted left and right by a distance equal to or less than the inter-pupil distance in the display area.

  Here, the interpupillary distance allows a human to recognize a left image viewed with the left eye and a right image viewed with the right eye as a single image, and merged. This is the distance to recognize the image at infinity. The interpupillary distance is generally the distance between the pupils (40 mm to 90 mm) when the lines of sight of the viewer's eyes are parallel. Therefore, the generation unit 201 generates a left image and a right image obtained by shifting the two-dimensional image by a distance greater than 0 and 90 mm or less in the left and right directions within the display area.

  Note that a human may be able to perform binocular fusion even when the line of sight of both eyes is opened from the parallel state to the left and right by about 2 to 3 degrees. Therefore, the interpupillary distance is a distance by which the left eye gaze deviates by 3 degrees or less (preferably 2 degrees) to the left from the parallel state, and the right eye gaze deviates by 3 degrees or less (preferably 2 degrees) from the parallel state to the right. May be. However, in such a case, the interpupillary distance increases as the distance between the viewer and the display surface increases.

  The display area for displaying the display image is, for example, an area formed on one screen such as a display surface of the television device or one window area displayed on the monitor of the computer. The display area may be an area formed by two screens such as a display surface of a head mounted display. For example, the generation unit 201 uses the left image so that the distance between the left image and the right image on the display area becomes the interpupillary distance according to the pixel size of the given two-dimensional image and the size of the display area. The distance on the data between the image and the right image is changed.

  For example, the generation unit 201 generates a left image and a right image by computer software calculation. Instead, the generation unit 201 generates an image in real time for a video signal transmitted or reproduced in real time.

  The image output unit 202 outputs a right-eye image and a left-eye image to the display device 10. Further, the image output unit 202 outputs the outer frame image to both the left eye and the right eye of the viewer. As an example, the image output unit 202 alternately outputs the left-eye image and the right-eye image to the display device 10 from the two-dimensional image generated by the generation unit 201, and displays information indicating the switching timing. Transmit to the synchronization control unit 203.

  The synchronization control unit 203 controls the ornamental glasses 30 worn by the user in synchronization, and blocks the field of view of the other eye while an image for one of the right eye and the left eye is displayed on the display device 10. The synchronization control unit 203 communicates with the ornamental glasses 30 wirelessly via the interface unit 204 and the adapter 210 to synchronously control the ornamental glasses 30. More specifically, the synchronization control unit 203 generates a synchronization signal indicating which one of the left and right lens shutters of the ornamental spectacles 30 is closed and the other lens shutter is opened, and the interface unit 204 and the adapter. It is supplied to the spectacles 30 for viewing through 210.

  In the present embodiment, the synchronization control unit 203 stores from the storage unit 205 a set value of a delay amount between the timing at which the image output unit 202 outputs an image to the display device 10 and the timing at which the display device 10 displays an image. get.

  Then, the synchronization control unit 203 changes the timing at which the ornamental spectacles 30 block the visual field of the left and right eyes to the timing at which the delay amount corresponding to the set value is compensated. When the display device 10 outputs a synchronization signal when displaying an image, the synchronization control unit 203 may receive the synchronization signal from the display device 10 and synchronize the ornamental glasses 30.

  The interface unit 204 has a function capable of communicating with an external device. As an example, the interface unit 204 transmits the synchronization signal received from the synchronization control unit 203 to the adapter 210 connected to the ornamental glasses 30. Here, the interface unit 204 may divert the image data transmission interface or the strobe interface of the imaging device 20.

  The storage unit 205 stores a set value of a delay amount between the timing at which the image output unit 202 outputs an image to the display device 10 and the timing at which the display device 10 displays an image. For the present embodiment, the storage unit 205 stores setting values corresponding to each of the plurality of types of display devices 10. Instead, the storage unit 205 may store a delay amount designated by the user as a set value.

  The adapter 210 is connected to the interface unit 204 by wire and communicates with the ornamental glasses 30 wirelessly. For example, the adapter 210 receives the synchronization signal from the synchronization control unit 203 via the interface unit 204 and transmits it to the ornamental glasses 30.

  FIG. 3 shows an example of setting information stored in the storage unit 205. The setting information stored in the storage unit 205 includes a device field and a delay amount field.

  The device field stores identification information of each display device. Here, the identification information stored in the device field may be a manufacturer name, model name, serial number, and the like.

  The delay amount field stores a delay amount from when the display device 10 receives an image from the imaging device 20 to when the image is displayed. Here, the delay amount indicates the time or phase difference between the received screen switching timing and the displayed screen switching timing, instead of the time until the same screen as the received screen is displayed. There may be.

  The synchronization control unit 203 searches the device field in the storage unit 205 based on the identification information of the display device. When the corresponding identification information is searched, the synchronization control unit 203 acquires the delay amount setting value from the corresponding delay amount field. Accordingly, the synchronization control unit 203 can change the timing to compensate for the delay amount corresponding to the set value corresponding to the display device 10 connected to the imaging device 20.

  FIG. 4 shows an example of a screen output to the display device 10. Here, the display device 10 alternately displays the left eye image and the right eye image received from the imaging device 20. In accordance with this, the ornamental glasses 30 are synchronously controlled by the synchronization control unit 203 in the imaging apparatus 20. As a result, when the display device 10 displays the left-eye image, the ornamental glasses 30 open the left-eye shutter and close the right-eye shutter. In addition, when the display device 10 displays the right-eye image, the ornamental glasses 30 open the right-eye shutter and close the left-eye shutter.

  The viewer can see the left image with the left eye and the right image with the right eye. By continuing this process, the viewer can feel a three-dimensional effect and a sense of realism in the object and the scenery that are being viewed, due to the parallax between the image for the left eye and the image for the right eye.

  FIG. 5 shows an example of a display point on the left image, a display point on the right image, and an image perceived by the user. When a human is looking at a two-dimensional image at a short distance, the image given to the left eye and the right eye are not the same but have parallax. From this parallax, a human recognizes that what he is looking at is a two-dimensional image. Further, when a human is looking at an object at infinity (for example, 10 m or more), the image given to the left eye and the image given to the right eye are the same with no parallax. When a human is looking at infinity, there is no parallax between the image given to the left eye and the image given to the right eye. I feel a feeling.

  The imaging device 20 generates a left-side image and a right-side image without parallax (that is, the same as each other) shifted to the left and right by the same distance as the distance between the pupils of the user. Then, the imaging device 20 provides the left image to the user's left eye and the right image to the user's right eye. As a result, the imaging device 20 can set the user's left eye and right eye line of sight in a parallel state, that is, the user's line of sight is not congested (the left eye and right eye line of sight do not intersect). Thereby, the imaging device 20 can make the user look at infinity. That is, for example, as illustrated in FIG. 5, the imaging device 20 can cause the user to perceive both point A (black circle point) and point B (triangular point) as points located at infinity.

  As described above, the imaging device 20 can provide the user with a stereoscopic image by giving the user an image with no parallax to the left eye and the right eye while viewing the image at infinity. For example, the imaging device 20 can give a realistic sensation as if looking out from a window, for example, in a landscape image or the like. Further, the imaging device 20 can give a real feeling as seen with a magnifying glass to an image taken at a short distance such as macro photography.

  The reason why the imaging device 20 can give the image a sense of reality such as a sense of presence and a real feeling as described above is estimated as follows. Since the imaging device 20 does not converge the user's line of sight, the image position cannot be specified by parallax. However, even when there is no parallax, the human estimates the position of the image from the actual size and angle of view of the object derived from common sense of experience. Then, humans unconsciously and instantaneously perform such position estimation, and obtain an actual size sense together with a stereoscopic effect. Therefore, it is presumed that the imaging device 20 can give the image a realistic feeling as described above without converging the user's line of sight.

  Further, when a human sees a moving image, a far object feels small movement, and a nearby object feels large movement. When a human sees a moving image, he / she feels a three-dimensional effect more strongly in the movement of such an object than in parallax. Therefore, the imaging device 20 can make the user feel a stereoscopic effect more strongly when displaying a moving image.

  Further, the imaging device 20 does not generate a phenomenon called a writing effect, in which a plane appears standing, and a phenomenon called a miniature garden effect, which reduces the feeling of spreading in the horizontal direction of the screen by emphasizing the depth and popping feeling. Therefore, according to the imaging device 20, it is possible to provide a stereoscopic image having a natural stereoscopic effect and a realistic sensation.

  Moreover, since the imaging device 20 does not congest the user's line of sight, there is no discrepancy between visual convergence and adjustment, and discomfort can be reduced. Moreover, since the imaging device 20 perceives a stereoscopic image at a position farther than the screen, it is possible to give the user a feeling of looking through a frame (for example, a window frame, a magnifying glass frame, or the like). Therefore, according to the imaging device 20, a phenomenon in which an image that pops out before the screen is unnaturally cut by the screen frame does not occur, and a natural stereoscopic image can be provided to the user.

  FIG. 6 shows an example of a non-corresponding region and crosstalk in which only one of the left image or the right image is displayed. In the left side portion of the display area when the outer frame image is not displayed, the left screen and the right screen are not displayed when the left image and the right image are generated by shifting one two-dimensional image left and right. (That is, a non-corresponding region where the right image and the left image do not overlap). Similarly, a non-corresponding area where the right screen is displayed but the left screen is not displayed exists in the right side portion of the display area when the outer frame image is not displayed.

  Further, crosstalk (or ghost) that appears as a vertical line is observed at a position inside the pupil distance from the right end of the display area and a position inside the pupil distance from the left end of the display area. Such a non-corresponding region and crosstalk give the viewer an unnatural feeling.

  FIG. 7 shows an example of the outer frame image. Therefore, the generation unit 201 preferably generates an outer frame image that covers at least the non-corresponding region and the crosstalk included in the display image. That is, it is preferable that the generation unit 201 generates an outer frame image in which the frame width of each of the left side and the right side is at least the inter-pupil distance. Thereby, according to the imaging device 20, the non-corresponding area | region and crosstalk part which give an unnatural feeling in a display image can be hidden, and a natural display image can be provided to a viewer.

  The generation unit 201 may generate a partial image of the outer frame. Accordingly, the generation unit 201 can form the outer frame of the display image together with the outer frame included in the display device 10.

  FIG. 8 shows a configuration example of the imaging device 20 in the case where an image is captured and light is emitted to provide information to the user. In this example, the imaging device 20 includes a light emitting unit 206. The synchronization control unit 203 generates a control signal for synchronously controlling the ornamental spectacles 30. Then, the synchronization control unit 203 controls the light emission of the light emitting unit 206 in order to transmit to the ornamental glasses 30 by optical communication.

  The light emitting unit 206 receives the synchronization signal transmitted from the synchronization control unit 203. The light emitting unit 206 emits light and transmits a synchronization signal to the ornamental glasses 30. In addition, as the light emission part 206 which the imaging device 20 has, you may divert the indicator of the imaging timer which light-emits when providing an image, and provides a user, or a display panel.

  FIG. 9 shows a configuration example of the ornamental spectacles 30 according to the present case. The ornamental glasses 30 are ornamental glasses that provide the right eye image and the left eye image displayed on the display device 10 to the right eye and the left eye of the user. The ornamental glasses 30 include a light receiving unit 300, a timing determination unit 301, a shutter control unit 302, and a shutter 303.

  The light receiving unit 300 is an example of a receiving unit of the ornamental spectacles 30. The light receiving unit 300 receives a synchronization signal for synchronizing the ornamental glasses 30 transmitted from the light emitting unit 206 of the imaging device 20 with the image switching timing of the display device 10. The light receiving unit 300 transmits the received synchronization signal to the timing determination unit 301.

  Based on the synchronization signal received from the light receiving unit 300, the timing determination unit 301 should provide a right selection timing at which the right eye image should be provided to the user's right eye and a left eye image to the viewer's left eye. Determine the left selection timing. Then, the timing determination unit 301 transmits the determined timing information to the shutter control unit 302. More specifically, the timing determination unit 301 generates timing information that determines the timing for closing the shutter of one lens and the timing for opening the shutter of the other lens based on the synchronization signal, and the shutter control unit To 302.

  From the timing information received from the timing determination unit 301, the shutter control unit 302 opens the right shutter provided on the right lens of the ornamental spectacles 30 at the right selection timing and closes the left shutter provided on the left lens at the left selection timing. The operation of closing the right shutter and opening the left shutter is controlled. That is, when the image displayed on the display device 10 is a left-eye image, the shutter control unit 302 opens the left-eye shutter and closes the right-eye shutter. When the image displayed on the display device 10 is a right-eye image, the shutter control unit 302 opens the right-eye shutter and closes the left-eye shutter.

  Here, when the ornamental spectacles 30 can receive the synchronization signal from the synchronization control unit 203 in the imaging device 20, the synchronization control unit 203 moves to the right according to the synchronization signal while receiving the synchronization signal. Adjust the selection timing and left selection timing. The shutter control unit 302 receives the synchronization signal adjusted by the synchronization control unit 203 and maintains the synchronization state.

  Thereafter, when the synchronization signal from the synchronization control unit 203 cannot be received, the timing determination unit 301 outputs the timing information while maintaining the adjusted right selection timing and left selection timing so that it can be used continuously. Keep doing. As a result, the shutter control unit 302 continues to open and close the right shutter and the left shutter based on the timing information that the timing determination unit 301 continues to output.

  Furthermore, the shutter control unit 302 controls the field of view of the right eye and the left eye so as not to cause discomfort to the viewer when a slight shift occurs in the synchronization control of the display device 10 and the ornamental glasses 30. There is a margin period in which the visual field of both eyes is blocked within the switching period in which the eyes to be blocked are switched. More specifically, the shutter control unit 302 performs control so that the shutter of one lens that has been opened is closed before the image displayed on the display device 10 is switched. The shutter control unit 302 then controls to open the shutter of the other lens after the image displayed on the display device 10 is switched. The shutter 303 operates the shutter function of the lens based on the control signal from the shutter control unit 302.

  As described above, the shutter control unit 302 provides a period during which the shutter is closed for both the left eye and the right eye. Thereby, the shutter control unit 302 allows a synchronization shift within a range in which the left-eye image and the right-eye image are switched within the period. With the imaging device 20 of the present example, the viewer can view the image by wearing the ornamental glasses 30 after receiving the synchronization signal, for example, by bringing the ornamental glasses 30 close to the imaging device 20.

  FIG. 10 shows an example of a hardware configuration of a computer 1900 according to the present embodiment. A computer 1900 according to this embodiment is connected to a CPU peripheral unit having a CPU 2000, a RAM 2020, a graphic controller 2075, and a display device 2080 that are connected to each other by a host controller 2082, and to the host controller 2082 by an input / output controller 2084. An input / output unit having a communication interface 2030, a hard disk drive 2040, and a DVD drive 2060, and a legacy input / output unit having a ROM 2010, a flexible disk drive 2050, and an input / output chip 2070 connected to the input / output controller 2084 Is provided.

  The host controller 2082 connects the RAM 2020 to the CPU 2000 and the graphic controller 2075 that access the RAM 2020 at a high transfer rate. The CPU 2000 operates based on programs stored in the ROM 2010 and the RAM 2020 and controls each unit. The graphic controller 2075 acquires image data generated by the CPU 2000 or the like on a frame buffer provided in the RAM 2020 and displays it on the display device 2080. Instead of this, the graphic controller 2075 may include a frame buffer for storing image data generated by the CPU 2000 or the like.

  The input / output controller 2084 connects the host controller 2082 to the communication interface 2030, the hard disk drive 2040, and the DVD drive 2060, which are relatively high-speed input / output devices. The communication interface 2030 communicates with other devices via a network. The hard disk drive 2040 stores programs and data used by the CPU 2000 in the computer 1900. The DVD drive 2060 reads a program or data from the DVD 2095 and provides it to the hard disk drive 2040 via the RAM 2020.

  The input / output controller 2084 is connected to the ROM 2010, the flexible disk drive 2050, and the relatively low-speed input / output device of the input / output chip 2070. The ROM 2010 stores a boot program that the computer 1900 executes at startup and / or a program that depends on the hardware of the computer 1900. The flexible disk drive 2050 reads a program or data from the flexible disk 2090 and provides it to the hard disk drive 2040 via the RAM 2020. The input / output chip 2070 connects the flexible disk drive 2050 to the input / output controller 2084 and inputs / outputs various input / output devices via, for example, a parallel port, a serial port, a keyboard port, a mouse port, and the like. Connect to controller 2084.

  A program provided to the hard disk drive 2040 via the RAM 2020 is stored in a recording medium such as the flexible disk 2090, the DVD 2095, or an IC card and provided by the user. The program is read from the recording medium, installed in the hard disk drive 2040 in the computer 1900 via the RAM 2020, and executed by the CPU 2000.

  A program installed in the computer 1900 and causing the computer 1900 to function as a computer for controlling the imaging apparatus 20 includes a generation module, an image output module, a synchronization control module, and a storage module. These programs or modules work on the CPU 2000 or the like to cause the computer 1900 to function as the generation unit 201, the image output unit 202, the synchronization control unit 203, and the storage unit 205, respectively.

  The information processing described in these programs is read by the computer 1900, thereby generating a unit 201, which is a specific means in which software and the various hardware resources described above cooperate, an image output unit 202, It functions as a synchronization control unit 203 and a storage unit 205. And the control computer of the imaging device 20 peculiar to a use purpose is constructed | assembled by implement | achieving the calculation or processing of the information according to the use purpose of the computer 1900 in this embodiment by these concrete means. .

  As an example, when communication is performed between the computer 1900 and an external device or the like, the CPU 2000 executes a communication program loaded on the RAM 2020 and executes a communication interface based on the processing content described in the communication program. A communication process is instructed to 2030. Under the control of the CPU 2000, the communication interface 2030 reads transmission data stored in a transmission buffer area or the like provided on a storage device such as the RAM 2020, the hard disk drive 2040, the flexible disk 2090, or the DVD 2095, and transmits it to the network. Alternatively, the reception data received from the network is written into a reception buffer area or the like provided on the storage device. As described above, the communication interface 2030 may transfer transmission / reception data to / from the storage device by a DMA (direct memory access) method. Instead, the CPU 2000 transfers the storage device or the communication interface 2030 as a transfer source. The transmission / reception data may be transferred by reading the data from the data and writing the data to the transfer destination 2030 or the storage device.

  In addition, the CPU 2000 reads all or necessary portions from files or databases stored in an external storage device such as the hard disk drive 2040, the DVD drive 2060 (DVD 2095), and the flexible disk drive 2050 (flexible disk 2090). The data is read into the RAM 2020 by DMA transfer or the like, and various processes are performed on the data on the RAM 2020. Then, CPU 2000 writes the processed data back to the external storage device by DMA transfer or the like. In such processing, since the RAM 2020 can be regarded as temporarily holding the contents of the external storage device, in the present embodiment, the RAM 2020 and the external storage device are collectively referred to as a memory, a storage unit, or a storage device. Various types of information such as various programs, data, tables, and databases in the present embodiment are stored on such a storage device and are subjected to information processing. Note that the CPU 2000 can also store a part of the RAM 2020 in the cache memory and perform reading and writing on the cache memory. Even in such a form, the cache memory bears a part of the function of the RAM 2020. Therefore, in the present embodiment, the cache memory is also included in the RAM 2020, the memory, and / or the storage device unless otherwise indicated. To do.

  In addition, the CPU 2000 performs various operations, such as various operations, information processing, condition determination, information search / replacement, etc., described in the present embodiment, specified for the data read from the RAM 2020 by the instruction sequence of the program. Is written back to the RAM 2020. For example, when performing the condition determination, the CPU 2000 determines whether the various variables shown in the present embodiment satisfy the conditions such as large, small, above, below, equal, etc., compared to other variables or constants. When the condition is satisfied (or not satisfied), the program branches to a different instruction sequence or calls a subroutine.

  Further, the CPU 2000 can search for information stored in a file or database in the storage device. For example, in the case where a plurality of entries in which the attribute value of the second attribute is associated with the attribute value of the first attribute are stored in the storage device, the CPU 2000 displays the plurality of entries stored in the storage device. The entry that matches the condition in which the attribute value of the first attribute is specified is retrieved, and the attribute value of the second attribute that is stored in the entry is read, thereby associating with the first attribute that satisfies the predetermined condition The attribute value of the specified second attribute can be obtained.

  The program or module shown above may be stored in an external recording medium. As the recording medium, in addition to the flexible disk 2090 and the DVD 2095, an optical recording medium such as DVD or CD, a magneto-optical recording medium such as MO, a tape medium, a semiconductor memory such as an IC card, and the like can be used.
