An image reproducing apparatus according to the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram showing a usage example of an image reproducing apparatus 101 according to the first embodiment of the present invention. The image reproduction device 101 is also called a storage device, and is a device that captures images captured by the cameras 102 and 103 into a storage device such as a hard disk and outputs the captured images to the television 104 in a slide show or the like.

  The camera 102 is a wirelessly connectable camera, and wirelessly communicates between the antenna 105 of the image reproducing apparatus 101 and the antenna 106 of the camera 102 to input the image captured by the camera 102 to the image reproducing apparatus 101.

The camera 103 is connected to a USB (Universal Serial Bus) interface 107 of the image reproducing apparatus 101 via a USB cable 108, and inputs an image captured by the camera 103 to the image reproducing apparatus 101. The cameras 102 and 103 are cameras capable of capturing not only 2D images (planar images) but also 3D images (stereoscopic images).

  The image reproducing apparatus 101 captures a 2D image or a 3D image from the camera 102 or the camera 103, outputs the 2D image or the 3D image from the output terminal 109 to the television 104 connected via the video cable 110, and displays the 2D image or the 3D image. The 3D image of the present embodiment can be viewed as a 3D image by wearing the 3D glasses 111.

  Here, the 3D image used in this embodiment will be briefly described with reference to FIG. In FIG. 2, it is assumed that two parallax images, a left-eye image 201 and a right-eye image 202, are captured by the camera 102 or the camera 103 as the 3D image. For example, the image 201 is red, the image 202 is blue, and the combined image 203 is displayed on the television 104. Since the two images that are combined and displayed have parallax, they appear to be double, but when you look at the image 203 displayed on the TV 104 by wearing the 3D glasses 111, one 3D image 204 Can be seen. Briefly, by providing a blue filter on the left side of the 3D glasses 111 and a red filter on the right side of the 3D glasses 111, the image 202 for the right eye cannot be seen by being filtered by blue in the left eye, and conversely, the image for the left eye in the right eye. Since 201 is filtered by red and cannot be seen, the image 201 for the left eye can be seen by the left eye, and the image 202 for the right eye can be seen by the right eye, which is recognized as a 3D image in the head. . As described above, the 3D image needs two pairs of parallax images for the left eye and the right eye.

  Next, the configurations of the camera 102 and the image reproducing apparatus 101 of FIG. 1 will be described with reference to FIG. In the block diagram of FIG. 3, the camera 102 is capable of capturing a 3D image, and has a left lens 302 and a right lens 303 so as to capture a parallax image of a pair of two images for the left eye and the right eye. The subject light incident from the left lens 302 is photoelectrically converted by the image pickup device 304, and the photoelectrically converted electric signal is converted into digital data by the A / D conversion unit 306 and stored in the buffer memory 307. Similarly, the subject light incident from the right lens 303 is photoelectrically converted by the image sensor 305, and the photoelectrically converted electric signal is converted into digital data by the A / D conversion unit 308, and is captured in the buffer memory 309.

  The image data captured in the buffer memories 307 and 309 is read by the CPU 301 via the bus 310, image processing is performed by the DSP (digital signal processing unit) 313, and the memory card 312 is transmitted via the memory card IF (interface) 311. Can be stored in.

  The camera 102 is controlled by the software of the CPU 301, and the user gives various operation instructions to the CPU 301 from the operation panel 316. For example, the CPU 301 is given operational instructions such as shutter operation, switching between 2D shooting and 3D shooting, reading and saving of images from the memory card 312, and transmission of images to the image reproducing apparatus 101.

  The transmission / reception unit 317 is for wirelessly transmitting an image from the camera 102 to the image reproducing apparatus 101, modulates the image selected by the user with the operation panel 316 into a high frequency signal, and the antenna 106 of the image reproducing apparatus 101 is modulated by the antenna 106. Send to.

  Next, the configuration of the image reproducing device 101 will be described. The image reproducing apparatus 101 is controlled by the software of the CPU 319, and the user gives various operation instructions to the CPU 319 from the operation panel 325. For example, the CPU 319 is instructed to capture an image from the camera 102, perform a file operation such as checking or searching an image stored in the memory card 323 or the hard disk (HDD) 324, or perform a slide show.

  The image received by the transmitting / receiving unit 318 is stored by the CPU 319 in the memory 321 or the HDD 324 via the bus 320, or in the memory card 323 connected via the memory card IF 322.

  A DSP (digital signal processing unit) 327 performs image processing according to an instruction from the CPU 319, and pseudo-converts a 2D image into a 3D image, or conversely converts a 3D image into a 2D image.

  The image output unit 326 converts an image output via the bus 320 into a video signal of composite, component, DVI, HDMI, etc., and outputs the video signal to the television 104 via the video cable 110 connected to the output terminal 109. Then, the image is displayed on the television 104.

  Here, the processing of the CPU 301 and the CPU 319 when communication is established between the transmission / reception unit 317 of the camera 102 and the transmission / reception unit 318 of the image reproduction apparatus 101 and an image is loaded into the memory 321, will be described using the flowchart of FIG. 4. To do.

First, the operation of the camera 102 will be described.
(Step S501) The power of the camera 102 is turned on.
(Step S502) When the CPU 301 of the camera 102 transmits a connection start signal from the transmission / reception unit 317 and the antenna 106 and receives a response signal from the image reproduction device 101, communication is established.
(Step S503) The user uses the operation panel 316 to select an image to be transmitted from the captured images stored in the memory card 312.
(Step S504) When the image to be transmitted is selected, the selected images are transmitted in order. (Step S505) Before the transmission of all the selected images is completed, the user operates the operation panel 316 to determine whether or not the operation is ended. When the operation is ended, the process proceeds to step S508.
(Step S506) It is determined whether or not all the selected images have been transmitted, and if all the images have been transmitted, the process proceeds to step S508.
(Step S507) The image to be transmitted next is selected from the selected images, and the process returns to step S504.
(Step S508) Notify the image reproducing apparatus 101 side that the image transmission processing is completed. (Step S509) The image transmission process ends.

In this way, the image selected by the camera 102 is transmitted to the image reproducing device 101 side. Next, the operation of the image reproducing device 101 will be described.
(Step S551) The image reproducing apparatus 101 is powered on.
(Step S552) Upon receiving the start signal sent from the camera 102 side, the CPU 319 of the image reproducing apparatus 101 sends a response signal via the transmitting / receiving unit 318 and the antenna 105, and communication with the camera 102 side is established. It becomes a state.
(Step S553) The image sent from the camera 102 is received.
(Step S554) The received image is stored in the memory 321, the HDD 324, or the memory card 323.
(Step S555) It is determined whether or not the end signal is received from the camera 102 side, and if the end signal is not received, the process returns to step S553 to receive the next image.
(Step S556) When the end signal is received from the camera 102 side, the image receiving process is ended.

  In this way, the image sent from the camera 102 side is received by the image reproducing device 101 and stored in the memory 321, the HDD 324, or the memory card 323. The image to be transmitted / received may be a 2D image or a 3D image.

Next, an operation when the slide show display is performed by the image reproducing device 101 will be described with reference to FIG. In this slide show, the display order of the images is sorted (sorted) by the designated method. Further, the 2D image is converted into a 3D image and displayed.
(Step S601) The image reproducing apparatus 101 is powered on.
(Step S602) The operation panel 325 of the image reproducing apparatus 101 selects an image to be subjected to the slide show from the images stored in the memory 321, the HDD 324, or the memory card 323. For example, by selecting a folder in the HDD 324, all the images stored in the folder are displayed as a slide show.
(Step S603) The selected images are sorted by the designated method. For example, assume that the image list 801 in FIG. 6A is selected. When the 3D image and the 2D image are sorted with respect to the image list 801, the display order in the slide show is rearranged as shown in the image list 802 of FIG. 6B, and the three images of the 3D image 803 are displayed. Def. 3D, ghi. 3D and pqr. 3D and 3D are displayed first, and the abc. 2D and jkl. 2D and mno. 2D and will be displayed later. Alternatively, when the images are sorted by the shooting time period for each hour, the order of display in the slide show is rearranged and two images 805 shot at 12:00 are displayed, as shown in the image list 804 of FIG. 6C. def. 3D and pqr. 3D and 3D are continuously displayed, and two images 806 abc. 2D and jkl. 2D and are grouped so as to be continuously displayed. The sorting criteria may be sorted according to criteria other than the above, such as shooting date and time and file names.
(Step S604) The images sorted in step S603 are sequentially read.
(Step S605) It is determined whether the read image is a 2D image or a 3D image, and if it is a 2D image, the process proceeds to step S606.
(Step S606) The DSP 327 pseudo-converts the 2D image into a 3D image based on a predetermined calculation. Various methods for converting a 2D image into a 3D image have been considered. For example, there is a method in which two parallax images are artificially constructed by partially changing the ratio of shifting the images.

  Further, at this time, for example, the characters "2D-> 3D" are superimposed on the converted 3D image so that the viewer can understand that the 2D image is converted to the 3D image. Alternatively, a graphic such as an icon may be displayed as the message information instead of the message information in text, or the color or pattern of the window of the screen displaying the image is converted into a 2D image and a normal 3D image, which is a 3D image. It may be different for and.

Although the 2D image is converted into the 3D image and unified into the 3D image here, when the output device does not support the 3D image or when the viewer intentionally displays the 2D image. When is selected, the 3D image may be converted into a 2D image and unified into a 2D image. Also in this case, for example, the character "3D->2D" is superimposed and output on the converted 2D image so that the viewer can understand that the 3D image is converted to the 2D image.
(Step S607) The 3D image or the image newly converted from the 2D image to the 3D image is output from the image output unit 326 via the output terminal 109 and the video cable 110, and the 3D image is displayed on the television 104. The 3D image is displayed as described with reference to FIG. (Step S608) Before displaying all the images in the slide show, the user operates the operation panel 325 to determine whether or not the operation is ended. If the operation is ended, the process proceeds to step S611.
(Step S609) It is determined whether or not it is the last image displayed in the slide show, and if it is the last image, the process proceeds to step S611.
(Step S610) When the image displayed in the slide show remains, the next image is read out, and the process returns to step S605.
(Step S611) The slide show ends.

  In the present embodiment, the case where the camera 102 and the image reproducing apparatus 101 are wirelessly connected has been described in FIG. 1, but the camera 103 and the image reproducing apparatus 101 may be connected by a cable such as a USB interface. I don't mind. In this case, as shown in FIG. 7, instead of the transmitting / receiving unit 318 and the antenna 105 of the image reproducing apparatus 101 and the transmitting / receiving unit 317 and the antenna 106 of the camera 102 of FIG. 3, the camera 103 has a USBIF (interface) 351. The image reproduction device 101b is provided with a USBIF 107, respectively, and is connected by a USB cable 108 for communication. Therefore, the operation is the same as the flowchart of FIG. 4 for transmitting an image from the camera 102 to the image reproducing apparatus 101 and the flowchart of FIG. 5 for performing a slide show display on the image reproducing apparatus 101, only with different communication media. It should be noted that, instead of the USB interface, an RS232C standard interface, an IEEE 1394 standard interface, or a LAN interface may be used.

  Further, in the present embodiment, the mode in which the camera 102 and the image reproducing apparatus 101 are connected wirelessly or the camera 103 and the image reproducing apparatus 101b are connected by wire has been described, but the function of the image reproducing apparatus is integrated in the camera. It does not matter. In this case, the camera can be directly connected to the television 104 to display a slide show, or the liquid crystal monitor 315 of the camera 102 can display the slide show for viewing.

  As described above, when an image in which 2D images and 3D images are mixed is displayed in a slide show, by converting the 2D image into a new 3D image and displaying the new 3D image, the viewer of the slide show can change the screen during the slide show. Since the 2D image is not switched to the 3D image, and vice versa, the 3D image is not switched to the 2D image, so that the user can enjoy the slide show without feeling discomfort or getting tired. In addition, the fact that the displayed image is an image converted from a 2D image to a 3D image or an image converted from a 3D image to a 2D image indicates that a figure such as a character or an icon or a color of a window of a screen is displayed. The viewer can easily check the pattern and the like.

  In the present embodiment, the 2D image is converted into the 3D image in steps S605 and S606 of FIG. 5, but steps S605 and S606 are deleted, and the 2D image and the 3D image are sorted in step S603. By doing so, the 2D image and the 3D image are continuously output, so that switching is required only once, and compared with the case where the slide show display is performed in the order in which the 2D image and the 3D image are mixed, the eyes of the viewer can be changed. You can reduce fatigue.

(Second embodiment)
Next, an image reproducing device according to the second embodiment of the present invention will be described. The configuration for connecting the camera 102 and the image reproducing device 101 is the same as that in FIG. 3 of the first embodiment. The image reproducing apparatus 101 of the present embodiment is provided with a function of converting a 2D image into a new 3D image on the camera 102 side. The image reproducing apparatus 101 temporarily stores the received image in the memory or receives it. While displaying the slide show.

  The operation of the camera 102 and the image reproducing apparatus 101 of this embodiment will be described with reference to the flowchart of FIG.

In FIG. 8, the processes with the same step numbers as those in FIG. Steps S501 to S503 are the same, and the image to be transmitted is selected.
(Step S701) Similar to step S603 of FIG. 5, the selected images are sorted by the designated method. That is, the 3D image and the 2D image are sorted, or the shooting time zone is set for each hour.
(Step S702) The images sorted in step S701 are sequentially read.
(Step S703) It is determined whether the read image is a 2D image or a 3D image, and if it is a 2D image, the process proceeds to step S704.
(Step S704) Similar to step S606 of FIG. 5, a 2D image is pseudo-converted into a 3D image based on a predetermined calculation. Note that this processing is performed by the DSP 313.

  The subsequent processing is the same as the flowchart of FIG. 4 of the first embodiment, and the image is transmitted in step S504, and the operation is performed until the user performs an end operation or finishes transmitting all the images.

  As described above, the camera 102 converts the 2D image into a new 3D image and transmits the new 3D image to the image reproducing apparatus 101, so that the processing load on the image reproducing apparatus 101 can be reduced. In the processing flow of FIG. 8 of the present embodiment, the received image is temporarily stored in the memory 321 in step S554, but the received image may be displayed in real time as a slide show. Alternatively, the slide show may be displayed on the liquid crystal monitor 315 of the camera 102 for viewing.

  Further, as in the first embodiment, when an image in which 2D images and 3D images are mixed is displayed in a slide show, by converting the 2D image into a new 3D image and displaying the new 3D image, the viewer of the slide show can The screen does not switch from a 2D image to a 3D image or vice versa during the slide show, so that the viewer can enjoy the slide show without feeling discomfort or getting tired. be able to.

(Third Embodiment)
Next, an image reproducing device according to the third embodiment of the present invention will be described. The configuration of the image reproducing device itself is the same as that of the image reproducing device 101 of FIG. 3 or the image reproducing device 101b of FIG. 7 of the first embodiment. However, in the present embodiment, the processes of steps S605 and S606 of FIG. 5 are different, and the following processes are performed.
(Step S605) It is determined whether or not the read image has changed from a 2D image to a 3D image. If the 2D image has changed to a 3D image, the process proceeds to step S606. If the 2D image or the 3D image remains unchanged, the step S607. Proceed to.
(Step S606) When the read image is changed from a 2D image to a 3D image, only one of the parallax images of the two pairs forming the 3D image is first output for a short time, and the process proceeds to step S607. . Note that in step S607, another parallax image is also output and output as a 3D image. Since the following operation is the same as that in FIG. 5, duplicated description will be omitted.

  Here, how an image is displayed in the present embodiment will be described with reference to FIG. FIG. 9 shows a state of an image displayed on the television 104 when time flows from top to bottom. It is assumed that the 2D image 701 is displayed until the time t1. If the image to be displayed next is a 3D image, in step S605 described above, it is determined whether the 2D image has changed to a 3D image, and in step S606, one of the two parallax images forming the 3D image is detected. One image 702 is displayed on the television 104 from time t1 to time t2. At this time, the CPU 319 of the image reproducing apparatus 101 synthesizes and displays the message information 704 of “change to 3D image” on the image 702 on the screen displayed on the television 104. At time t2 after the lapse of a predetermined time, the 3D image 703 including another parallax image paired with the image 702 is displayed on the television 104.

  As described above, when a slide show display of an image in which 2D images and 3D images are mixed is performed, when switching from a 2D image to a 3D image, one of the parallax images of a pair of two images forming the 3D image is converted into a 2D image. By changing the 2D image to the 3D image after a certain period of time, the eyes can be gradually acclimated, and discomfort at the time of change can be reduced. In particular, the viewer can make a psychological preparation by displaying the message information notifying that the 3D image is about to change. Note that displaying message information such as "please put on the 3D glasses 111" can prompt the viewer to prepare the 3D glasses 111, which is more effective. Alternatively, instead of the message information in text, a graphic such as an icon may be displayed as the message information, or the color or pattern of the window of the screen displaying the image may be changed between the 2D image and the 3D image.

  Further, when the 2D image is switched to the 3D image, any one of the parallax images of the two pairs forming the 3D image is not displayed as the 2D image, but as shown in FIG. Alternatively, another 3D image 705 may be displayed. Particularly in this case, it is preferable to insert an image with a perspective that allows the viewer's eyes to easily get used to the 3D image. Alternatively, a white screen or a black screen may be inserted as the image 705 to reset the viewer's sense of eyes.

  Furthermore, the image effect displayed in the slide show may be changed when the 2D image is switched to the 3D image or when the 3D image is switched to the 2D image. For example, two types of slide-in and slide-out speeds may be provided, and the slide-in and slide-out speeds of 2D images may be increased and the slide-in and slide-out speeds of 3D images may be reduced. Alternatively, two types of slide-in and slide-out methods may be provided so that when the 2D image is changed to the 3D image, the slide-in is performed from the left side, and when the 3D image is changed to the 2D image, the slide-in is performed from the right side. I do not care. In addition to the slide-in and slide-out image effects, the presence or absence of zoom processing for enlarging a part of the displayed screen may be changed.

  Alternatively, not only when the 2D image is switched to the 3D image, the image effect of displaying the 2D image and the image effect of displaying the 3D image may be changed. For example, the sepia tone image effect may be provided while the 2D image is displayed, and the star display image effect may be provided while the 3D image is displayed.

  In this way, when the 2D image is switched to the 3D image or when the 3D image is switched to the 2D image, by changing the image effect displayed in the slide show, the viewer can know the change of the image type in advance. Can make psychological preparation.

(Fourth Embodiment)
Next, an image reproducing apparatus according to the fourth embodiment of the present invention will be described. The configuration of the image reproducing device itself is the same as that of the image reproducing device 101 of FIG. 3 or the image reproducing device 101b of FIG. 7 of the first embodiment. In this embodiment, file operations for 3D images and 2D images, such as the sort processing described in the previous embodiment, will be described.

  FIG. 11 illustrates a state of the screen of the television 104 when a file is operated. FIG. 11A shows a screen 811 in which folders for storing 2D images and 3D images are displayed. A folder icon 812 for only line drawings indicates a folder for storing only 2D images, and a shaded stereoscopic tone is displayed. The folder icon 813 indicates a folder in which only 3D images are stored. Furthermore, a three-dimensional folder icon 814 in which a part is a line drawing and the remaining part is shaded indicates a folder in which 2D images and 3D images are stored in a mixed manner.

  Now, if the user operates the operation panel 325 of the image reproducing apparatus 101 to instruct selection of a folder in which only 2D images are stored on the screen 811, which is shown in FIG. On the screen 811, all folder icons 812 in which only 2D images are stored are selected. A shaded portion surrounded by a dotted line 815 in FIG. 11B is a folder icon 812 that stores only the selected 2D image. On the contrary, FIG. 7C shows a state in which selection of a folder in which only 3D images are stored is instructed, and the CPU 319 displays all folder icons 813 in which only 3D images are stored on the screen 811. select. A shaded portion surrounded by a dotted line 816 is a folder icon 813 that stores only the selected 3D image. Note that the same can be done when selecting a folder icon in which 2D images and 3D images are stored in a mixed manner.

  In this way, by displaying different folder icons in a folder in which only 2D images are stored, a folder in which only 3D images are stored, or a folder in which 2D images and 3D images are mixed, the user can display the folder icons. By looking at the screen, it is possible to easily determine in which folder the 2D image or the 3D image is stored. In addition, a user can select all the folders having the same image format, such as a folder storing only 2D images and a folder storing only 3D images, so that images of the same format can be moved. , Easy to copy.

  Next, a case of operating the screen on which the image file is displayed will be described with reference to FIG. FIG. 11A shows a state of a screen 821 on which an image file storing a 2D image or a 3D image is displayed. As attribute information of the image file, 2D or 3D is added to the extension, and information indicating whether the type is a 2D image or a 3D image is displayed.

  Now, assuming that the user operates the operation panel 325 of the image reproducing apparatus 101 to instruct selection of only 2D images on the screen 821 in which FIG. Select all images only. The shaded portion surrounded by dotted lines 822, 823 and 824 in FIG. 7B is the selected 2D image file. On the contrary, FIG. 6C shows a state in which selection of only 3D images is instructed. The CPU 319 selects only all 3D images on the screen 821. The shaded portion surrounded by dotted lines 825, 826 and 827 is the selected 3D image file.

  Thus, by adding different extensions to the 2D image and the 3D image, the user can easily determine whether the displayed file is the 2D image or the 3D image. Also, since only 2D image files and 3D image files can be selected collectively by the user's operation, it becomes easy to simultaneously move or copy images of the same form.

  Here, the 3D image file will be described. The 3D image of this embodiment is composed of a pair of parallax images, as described in FIG. Therefore, two parallax images for the right eye and for the left eye are required, but when making a 3D image into a file, a method of making another two image files and a method of making one image file are considered. To be The 3D image file in FIG. 12 described above is based on the method of forming one image file. For example, the def. File of the 3D image file surrounded by the dotted line 825 in FIG. Two parallax images for the right eye and for the left eye are stored in 3D, and the CPU 319 determines that the def. Information for separating into two parallax images is added to the image file so that the parallax images can be separated into two when reading 3D.

  On the other hand, in the method of converting the two parallax images for the right eye and the left eye into two different image files, for example, as shown in FIG. 13, in the screen 831 where the image files are displayed, the extension is 3DL. The def. Of the image file 832. 3DL and the def. 3DR is displayed as if it were two different image files. In this case, when the CPU 319 reads a 3D image file, it searches for the same file name def excluding the extension, and reads the extension 3DL for the left eye and the extension 3DR for the right eye, respectively. Display a 3D image.

  Next, a method of performing an image search using the correlation of images will be described. For example, when the user operates the operation panel 325 of the image reproduction apparatus 101 to instruct to search for a certain image, for example, the CPU 319 performs the image search using the correlation as it is for the file of the 2D image and the 3D image. With respect to the file, the image search is performed with only one of the parallax images in the pair of two as the search target. In this case, for two parallax images for the right eye and the left eye as described in FIG. 12, which are made into one 3D image file, only the data of one side image of the image file is searched. Alternatively, in the case where the two parallax images for the right eye and the left eye as described in FIG. 13 are made into two different image files, for example, only the image file with the extension 3DL is searched and expanded. An image file whose child is 3DR is not set as a search target.

  In this way, when performing an image search from an image file in which 2D images and 3D images coexist, only one of the parallax images of a pair of 3D images is set as the search target, so that the image search time can be reduced. It can be shortened. It should be noted that all the two parallax images may be the search targets, but since the two parallax images have a correlation, it is only necessary to select one of the parallax images to search for the two parallax images. It is possible to obtain the same search result as when the search target is set.

  Next, a case of displaying thumbnails of sorted and searched images will be described with reference to FIG. FIG. 14A shows a screen 711 in which only the 2D image 712 is thumbnail-displayed on the television 104, and FIG. 14B shows a screen 713 in which only the 3D image 714 is thumbnail-displayed on the television 104. For example, if the user operates the operation panel 325 of the image reproducing apparatus 101 to instruct thumbnail display of an image file list in which 2D images and 3D images are mixed as shown in FIG. 12A, the CPU 319 Only 2D images are extracted from the image file list on the screen 821, and thumbnail images of only 2D images as shown in FIG. The thumbnail of the 3D image is divided into the following screens, and only the 3D image is displayed on one screen as shown in FIG. At this time, for example, when there are 7 2D images and 5 3D images with a screen size capable of displaying 12 thumbnail images on 1 screen, as shown in FIG. 14A, 7 2D images are displayed on 1 screen. A thumbnail is displayed on the screen, and five blanks are left blank, and the three 3D images are displayed on the next screen as shown in FIG.

  In this way, when displaying the image file list in which 2D images and 3D images coexist as thumbnails, the 2D images and 3D images are displayed separately on different screens, so the eyes of the viewer are not tired. In particular, when the 3D image is displayed as a thumbnail, the 3D image can be viewed by wearing the 3D glasses 111.

  In each of the embodiments, the case of a 3D image viewed by wearing red and blue glasses has been described, but other methods of obtaining a 3D image include a method using polarized light and a method of wearing glasses with a liquid crystal shutter. , There are things that have undergone special processing that causes parallax on the TV display itself. Even with such a 3D image, the same effect as that of the present embodiment can be obtained by processing the image data in the same manner. In particular, when 3D images by different methods are mixed, the sorting described in each embodiment may be performed for each type of 3D image.

  Although the present invention has been described in detail above, the above-described embodiments and modifications thereof are merely examples of the invention, and the invention is not limited thereto. Obviously, modifications can be made without departing from the invention.
