  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 configuration of an image generation apparatus 10 according to the present embodiment. The image generation apparatus 10 according to the present embodiment generates a right-eye image and a left-eye image to be presented to the viewer's right eye and left eye. Thereby, the image generation device 10 can present a stereoscopic image to the viewer. Furthermore, the image generation device 10 generates a right-eye image and a left-eye image that appear to shine a stereoscopic image.

  The image generation apparatus 10 includes a generation unit 22, a subject detection unit 24, a region detection unit 26, a change unit 28, and an output unit 30. The generation unit 22 generates a right-eye image to be given to the viewer's right eye and a left-eye image to be given to the viewer's left eye.

  For example, the generation unit 22 may be an imaging device for generating a stereoscopic image that captures a subject from a viewpoint corresponding to the right eye and a viewpoint corresponding to the left eye to generate a right eye image and a left eye image. . In addition, as an example, the generation unit 22 generates a right eye image and a left eye image obtained by viewing a virtual three-dimensional object from a viewpoint corresponding to the right eye and a viewpoint corresponding to the left eye, using computer graphics or the like. It may be a device that performs. The generation unit 22 may be a playback device that plays back the right-eye image and the left-eye image generated in this way from a recording medium.

  The subject detection unit 24 detects a predetermined subject in the right eye image and the left eye image. As an example, the subject detection unit 24 detects a subject to be shined. For example, the subject detection unit 24 detects subjects that are specularly reflected, such as glass, metal surfaces, and water. For example, the subject detection unit 24 detects a subject that emits light, such as the sun, fire, and light.

  Here, the specular reflection is a reflection on the surface of the object, and in this case, the reflected light is often not colored and is almost white. In many cases, the specular reflection is close to regular reflection. In addition, the specular reflection is intended to have a directivity depending on the direction of the light source on the surface of the object, and is not necessarily a reflection on the mirror surface. For example, when the intensity of the light source that illuminates an object is sufficiently strong, the viewer feels that the reflected light component close to regular reflection is shining even on a rough surface, so such an area is mirrored. It may be a reflective region.

  The region detection unit 26 detects a target region where the subject is shining in the right-eye image and the left-eye image. For example, the area detection unit 26 detects an area that is specularly reflected on the surface of the subject, such as glass, a metal surface, and water. Further, for example, the area detection unit 26 detects a light emitting area on the surface of the subject. Further, as an example, the region detection unit 26 may detect a region having a luminance equal to or higher than a predetermined threshold value as a target region. Further, as an example, the region detection unit 26 determines whether the level is equal to or higher than a predetermined threshold value for each color (for example, for each R, G, B), and detects the target region. Also good.

  The changing unit 28 changes at least one of the color tone and brightness of the corresponding target region between the right-eye image and the left-eye image generated by the generating unit 22. For example, the changing unit 28 changes at least one of the color tone and brightness of the subject detected by the subject detection unit 24 between the right-eye image and the left-eye image. For example, the changing unit 28 changes at least one of the color tone and brightness of the target area detected by the area detecting unit 26 between the right-eye image and the left-eye image.

  Further, the changing unit 28 changes at least one of the color tone and the brightness with a partial region in the frame as a target region. Thereby, the changing unit 28 can present a stereoscopic image in which only a part of the screen is shining.

  The output unit 30 outputs the right eye image and the left eye image changed by the changing unit 28. In the present embodiment, the output unit 30 provides the right-eye image to the viewer's right eye and the left-eye image to the viewer's left eye. Note that the output unit 30 may be configured to output right-eye image data and left-eye image data to a display device that displays a stereoscopic image to a viewer.

  In the present embodiment, the output unit 30 includes a display unit 32 and image separation glasses 34. The display unit 32 includes a plurality of right eye pixels for displaying a right eye image and a plurality of left eye images for displaying a left eye image. The right-eye pixel and the left-eye pixel output light having different polarizations.

  The image separation glasses 34 are worn by the viewer. The image separation glasses 34 include a right-eye filter provided at a position corresponding to the right eye when worn, and a left-eye filter provided at a position corresponding to the left eye when worn. The right-eye filter transmits the polarization component of the light output from the right-eye pixel and blocks other polarization components. The left-eye filter transmits the polarization component of the light output from the left-eye pixel and blocks other polarization components.

  Such an output unit 30 can provide a right-eye image to the viewer's right eye and a left-eye image to the viewer's left eye. Thereby, the output unit 30 can present a stereoscopic image to the viewer.

  The output unit 30 may have another configuration as long as it can provide the right eye image to the viewer's right eye and the left eye image to the viewer's left eye. . As an example, the output unit 30 displays the right-eye image and the left-eye image by alternately switching them, and opens the right-eye shutter during the right-eye image display period to display the left-eye image. The image separation glasses 34 may be configured to close the shutter, open the left-eye shutter during the left-eye image display period, and close the right-eye shutter.

  The output unit 30 may be a head mounted display as an example. For example, the output unit 30 may be an autostereoscopic display device that does not use the image separation glasses 34. Further, the output unit 30 may be a display panel using a parallax barrier, a lenticular, or the like as an example.

  FIG. 2 shows an example of an image presented to the viewer by the image generation apparatus 10 according to the present embodiment. When the human sees the mirror surface, he unconsciously determines that the image reflected on the mirror surface is a virtual image, that is, the object is a mirror surface.

  This is because the color or brightness of an arbitrary point on the mirror surface is different between when viewed with the right eye and when viewed with the left eye, and therefore, an object that looks like this is determined to be a mirror surface. There seems to be a factor. Therefore, the image generation device 10 changes at least one of the color tone and brightness of the corresponding target region between the right-eye image and the left-eye image displayed to the viewer. As a result, according to the image generation device 10, it is possible to present the viewer with a stereoscopic image that looks shining like a mirror surface or a glossy surface.

  The subject detection unit 24 registers, for example, a predetermined subject shape such as a specularly reflective subject such as glass and a mirror or a light and subject such as a light emitting subject such as fire. The subject detection unit 24 detects such a registered subject from the right-eye image and the left-eye image by object matching. For example, the changing unit 28 changes at least one of the color tone and the brightness of at least a part of the subject detected by the subject detecting unit 24 between the right-eye image and the left-eye image. As a result, the image generation apparatus 10 can present a stereoscopic image that looks like a predetermined subject is shining to the viewer.

  In addition, the area detection unit 26 detects a target area that should be shown shining on a part of the surface of the subject. For example, the area detection unit 26 detects a target area for specular reflection such as glass or a mirror or a target area for light emission on the surface of the subject. The changing unit 28 changes at least one of the color tone and the brightness of the corresponding target area detected by the area detecting unit 26 between the right-eye image and the left-eye image. Thereby, the image generation apparatus 10 can present a viewer with a stereoscopic image in which the glass and the mirror or the light emitting portion appear to be shining.

  For example, the changing unit 28 may change the distribution of at least one of the color tone and the brightness in the target region between the right-eye image and the left-eye image. Thereby, the image generation device 10 can present the viewer with a stereoscopic image in which the target area naturally shines.

  In addition, for example, the changing unit 28 uses the right eye so that the average value of at least one of the color tone and the brightness of the target region in the right eye image and the left eye image is substantially the same before and after the change. At least one of the color tone and brightness of the target area may be changed between the image for use and the image for the left eye. Thereby, the image generation apparatus 10 can increase the brightness in the target region without changing the color tone and brightness of the original image.

  For example, the changing unit 28 may bring one of the target region in the right-eye image and the target region in the left-eye image closer to blue and the other closer to yellow. Thereby, the image generation device 10 can present the viewer with a stereoscopic image that shines more naturally.

  For example, the changing unit 28 may bring one of the target region in the right-eye image and the target region in the left-eye image closer to blue and the other closer to red. Even in this way, the image generation device 10 can present a stereoscopic image that shines more naturally to the viewer.

  FIG. 3 shows an example of a method for generating a right eye image and a left eye image. For example, the generation unit 22 generates a right-eye image and a left-eye image by shifting the common image to the left and right. Thereby, the production | generation part 22 can produce | generate the image for right eyes and the image for left eyes for stereoscopic vision from an image which is not produced | generated for stereoscopic vision by simple process.

  More specifically, the generation unit 22 generates a right-eye image by horizontally shifting the common image to the right side, and generates a left-eye image by horizontally shifting the common image to the left side. In this case, the generation unit 22 sets the difference in the relative position in the horizontal direction between the left-eye image and the right-eye image to be equal to or less than the inter-pupil distance L of the viewer. For example, the generation unit 22 sets an image obtained by shifting the common image to the left by L / 2 as an image for the left eye, and sets an image obtained by shifting the common image to the right by L / 2 as an image for the right eye.

  Here, the interpupillary distance L is a distance (40 mm to 90 mm) between the pupils of the viewer. When the left-eye image and the right-eye image are displayed at positions separated by the interpupillary distance L, the viewer can display the left-eye image displayed with the left eye and the right-eye image viewed with the right eye. The display object can be fused and recognized as one image, and the fused image can be recognized at infinity. Accordingly, the generation unit 22 can present a stereoscopic image to the viewer by setting the difference in relative position between the right-eye image and the left-eye image to be equal to or less than the inter-pupil distance L.

  Further, when the right image and the left eye image are generated by shifting the common image to the left and right, a blank portion is generated at the left end of the right eye image. Similarly, a blank portion is also generated at the right end of the left-eye image. Since these regions can give an image to only one of the right eye and the left eye, they may be an obstacle to giving a natural stereoscopic effect to the viewer.

  Therefore, as an example, the generation unit 22 may add the left end image to the left blank portion of the right eye image and add the right end image to the right blank portion of the left eye image. For example, the generation unit 22 generates a right end image by copying an image of the right end region of the right eye image, and generates a left end image by copying an image of the left end region of the left eye image. In this case, the generation unit 22 may blur the right end image and the left end image. Thereby, the production | generation part 22 can show the same image to a right eye and a left eye in an edge part, and can reduce the unnaturalness in an edge part.

  For example, the generation unit 22 generates a left end image by enlarging a predetermined range from the left end of the display area for the right eye image to the left side, and generates an image in the predetermined range from the right end of the display area for the left eye image. The right end image is generated. Thereby, the production | generation part 22 can show a viewer the natural three-dimensional image with which the image continued in the edge part.

  For example, the generation unit 22 may display a frame image such as black on the right end portion and the left end portion of the right eye image and the left eye image, respectively. Thereby, the production | generation part 22 eliminates the area | region which does not give the stereoscopic effect in the left end and the right end, and can give a stereoscopic effect in all the area | regions within a frame. Furthermore, by displaying such a frame image, it is possible to give the viewer a sense of seeing an object through a frame (window frame, magnifying glass frame, etc.), so that a natural three-dimensional effect can be given to the viewer. Can be provided.

  For example, the generation unit 22 may be configured to generate the same right-eye image and left-eye image that have no relative position difference and no parallax. In this case, the image generation apparatus 10 can present a two-dimensional image instead of a stereoscopic image to the viewer. Even in such a case, the changing unit 28 changes at least one of the color tone and brightness of the corresponding target area between the right-eye image and the left-eye image, so that the image generation apparatus 10 Can be presented to the viewer.

  FIG. 4 shows a configuration of the image generation apparatus 10 according to a modification of the present embodiment. Since the image generation apparatus 10 according to the present modification has substantially the same configuration and function as the image generation apparatus 10 shown in FIG. 1, the configuration and function substantially the same as the members included in the image generation apparatus 10 shown in FIG. The same reference numerals are given to the members, and the description will be omitted except for the differences.

  The image generation apparatus 10 according to this modification further includes an acquisition unit 42 and an adjustment unit 44. The acquisition unit 42 acquires whether the viewer's dominant eye is left or right. For example, the acquisition unit 42 acquires whether the dominant eye is left or right based on information input by the viewer.

  The change unit 28 changes the amount of change in at least one of the color tone and brightness of the target region in the right eye image and the color tone of the target region in the left eye image depending on whether the dominant eye of the viewer is right or left. And the change amount of at least one of the brightness. For example, the change unit 28 changes at least one of the color tone and brightness of the image corresponding to the dominant eye of the viewer among the right eye image and the left eye image, and the color tone of the image not corresponding to the dominant eye. And do not change the brightness. Thereby, the change part 28 can make a viewer feel strong shine.

  The adjusting unit 44 adjusts the amount of change in at least one of the color tone and the brightness by the changing unit 28 in accordance with an instruction from the viewer. Thereby, for example, when the viewer feels that the brightness of the target area is too strong, the adjustment unit 44 reduces the change amount, and when the viewer feels that the brightness of the target area is too weak, The amount of change can be increased.

  FIG. 5 shows the display unit 32 that presents a different stereoscopic image for each of a plurality of viewpoints having different horizontal angles when viewing the display surface. For example, the generation unit 22 presents a right-eye image and a left-eye image to be presented to each of a plurality of viewpoints having different horizontal angles when viewing a display surface on which a right-eye image and a left-eye image are displayed. Is generated.

  And the display part 32 displays the image for right eyes and the image for left eyes corresponding to the right eye and left eye of the viewer of the viewpoint of each angle of a horizontal direction. Thereby, the image generation apparatus 10 can present a three-dimensional image that changes according to the horizontal angle of viewing the display surface to the viewer.

  Here, in such a case, the changing unit 28 monotonously changes at least one of the color tone and the brightness of the target area in accordance with the change in the horizontal angle between the plurality of viewpoints. Thereby, the change part 28 can show a viewer the three-dimensional image from which brightness differs according to the angle of the horizontal direction which looks at a display surface.

  As an example, the changing unit 28 changes at least one of the color tone and brightness of the target area between the right-eye image and the left-eye image, and changes the target area according to the horizontal angle of viewing the display surface. At least one of color tone and brightness may be monotonously increased or monotonously decreased. As an example, the changing unit 28 may change at least one of the color tone and brightness of the target area in proportion to the horizontal angle of viewing the display surface. Further, to increase or decrease the color tone monotonously is, for example, an operation to monotonously increase or decrease the levels of all primary colors.

  FIG. 6 shows an example of image separation glasses 34 with a massage device according to the present embodiment. When viewing a stereoscopic image for a long time, the viewer may feel tired. Therefore, the image separation glasses 34 may be configured to further include right and left massage devices 50.

  As an example, the right massage device 50 applies pressure to the right side of the viewer's head. As an example, the left massage device 50 applies pressure to the left side of the viewer's head.

  Each of the right and left massage devices 50 is provided integrally with the main body of the image separation glasses 34, for example. Each massage device 50 includes a distal end portion 52 and a support portion 54.

  The distal end 52 is abutted against the temple of the viewer when the image separation glasses 34 are worn. The support part 54 supports the front-end | tip part 52, and applies the force which presses the said front-end | tip part 52 against a viewer's head. The massage device 50 may be configured to further include a vibration unit that vibrates the distal end portion 52. Such a massage device 50 can reduce fatigue caused by viewing a stereoscopic image.

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 CD-ROM 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 CD-ROM drive 2060 reads a program or data from the CD-ROM 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 CD-ROM 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 the image generation apparatus 10 includes a generation module, a subject detection module, a region detection module, a change module, and an output module. These programs or modules work on the CPU 2000 or the like to cause the computer 1900 to function as the generation unit 22, the subject detection unit 24, the region detection unit 26, the change unit 28, and the output unit 30, respectively.

And the specific image generation apparatus 10 according to the intended purpose is constructed | assembled by implement | achieving the calculation or processing of the information according to the intended purpose of the computer 1900 in this embodiment by these specific 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 CD-ROM 2095, and sends it to the network. The reception data transmitted or 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 communication interface 2030 or the storage device of the transfer destination.

  The CPU 2000 is all or necessary from among files or databases stored in an external storage device such as a hard disk drive 2040, a CD-ROM drive 2060 (CD-ROM 2095), and a flexible disk drive 2050 (flexible disk 2090). This portion 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 hold 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.

For example, when performing the condition determination, the CPU 2000 determines whether or not 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. If 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 CD-ROM 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.
