Although an explanation will be given, the extensions that can be handled in the present embodiment are not limited to these, and other extensions may be used.

  Further, in the present embodiment, as a display method for stereoscopically displaying a video (image) to be displayed, a side-by-side (Side By-Side) method and a top-and-bottom (Top And Bottom) method are mainly used. handle. Here, the side-by-side method is to extract a left-eye image and a right-eye image by dividing a single image into left and right parts, and extending each of the left-eye image and the right-eye image in the horizontal direction. This is a display method for alternately displaying by a time-division display method. Therefore, the video (image) indicated by the video (image) file that can be stereoscopically displayed in the stereoscopic display mode using the side-by-side method includes a left-eye image and a right-eye image for each image. In the top-and-bottom method, a left-eye image and a right-eye image are extracted by dividing a single image into two vertically, and each of the left-eye image and the right-eye image is stretched in the vertical direction. Thereafter, this is a display method in which the images are alternately displayed by a time-division display method. Therefore, the video (image) indicated by the video (image) file that can be stereoscopically displayed in the stereoscopic display mode using the top-and-bottom method includes a left-eye image and a right-eye image for each image. .

  FIG. 4 is a table showing an example of a file name of a video (image) file indicating a video (image) to be displayed. As shown in FIG. 4, the name portion of the file name includes specific character strings such as “2DORG”, “2D3D”, “3DSBS”, “3DTAB”.

  When the character string “3DSBS” is included in the file name of the video (image) file representing the video (image) to be displayed, the CPU 118 instructs the 2D / 3D processing unit 130 to display the display target. A control signal S_3DSBS for supplying a three-dimensional display of a video (image) in a three-dimensional display mode using a side-by-side method is supplied.

(3DTAB)
The character string “3DTAB” is a video (image) file in which a video (image) file including the character string as a part of the name portion of the file name is to be stereoscopically displayed in the stereoscopic display mode using the top-and-bottom method. It shows that there is.

  When the character string “3DTAB” is included in the file name of the video (image) file representing the video (image) to be displayed, the CPU 118 instructs the 2D / 3D processing unit 130 to display the display target. A control signal S_3DTAB for displaying a video (image) in a stereoscopic display mode using a top-and-bottom method is supplied.

(2DORG)
The character string “2DORG” indicates that a video (image) file including the character string as a part of the name portion of the file name is a video (image) file to be displayed in a plane.

  When the character string “2DORG” is included in the file name of the video (image) file representing the video (image) to be displayed, the CPU 118 instructs the 2D / 3D processing unit 130 of the display target. A control signal S_2DORG for displaying a video (image) on a plane is supplied.

(2D3D)
The character string “2D3D” indicates that a video (image) file including the character string as a part of the name portion of the file name is a video (image) file to be displayed in a pseudo three-dimensional manner.

  When the character string “2D3D” is included in the file name of the video (image) file representing the video (image) to be displayed, the CPU 118 instructs the 2D / 3D processing unit 130 of the display target. A control signal S_2D3D for pseudo-stereoscopic display of a video (image) is supplied.

(If no identifier is included)
A video (image) file in which the name portion of the file name does not include a specific character string as an identifier is a file to display the image indicated by the video (image) file as it is. Therefore, when the image indicated by the video (image) file is an image for flat display, the image for flat display is displayed as it is, and the image indicated by the video (image) file is an image for stereoscopic display. In some cases, the stereoscopic display image is displayed as it is.

  When the file name of the video (image) file representing the video (image) to be displayed does not include a specific character string as an identifier, the CPU 118 displays the display on the 2D / 3D processing unit 130. A control signal S_O for displaying the target video (image) as it is is supplied.

  In the above example, the case where “2DORG”, “2D3D”, “3DSBS”, and “3DTAB” are used as the specific character string as the identifier has been described, but the present embodiment is limited to this. It is not a thing. The specific character string as the identifier only needs to be distinguishable from each other. For example, instead of “2DORG”, “2D3D”, “3DSBS”, and “3DTAB”, “AA”, “BB”, “ Shorter character strings such as “CC” and “DD” may be used.

  Further, in the above example, four different character strings are used to distinguish four types of processing having different processing contents from each other. However, 3DTV 1 uses different N (N May be configured to perform two types of processing. In this case, N types of different identifiers corresponding to each of the N types of processing may be used.

  For example, the 3D TV 1 may be configured to display a stereoscopic video (image) indicated by a frame packing type stereoscopic display file as well as the side-by-side method and the top-and-bottom method. A 3D display file of the system can be identified using an identifier such as “3DFS”, for example.

  In addition, the correspondence information between the character string that can be identified as an identifier by the CPU 118 and the processing content designated by the character string is recorded in advance in a memory included in the 3D TV 1 or a removable storage medium. The 2D / 3D processing unit 130 can be controlled with reference to the correspondence information.

  In addition, the character string of the identifier in the name part of the file name and the character string of the part other than the identifier may be set by the user or automatically set in the external device. May be. However, it is assumed that the character string as an identifier assigned to the name portion of the file name is selected from character strings that the CPU 118 can identify as the identifier.

  In the above example, in the name part of the file name, “_” (underscore) is used as a separator for distinguishing between a specific character string as an identifier and a part other than the specific character string. Other symbols (for example, “-” (minus)) may be used. In addition, as long as the CPU 118 can extract a specific character string as an identifier, there may be no separator between the specific character string and a portion other than the specific character string.

(2D / 3D processing unit 130)
Next, the 2D / 3D processing unit 130 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a configuration of the 2D / 3D processing unit 130. As illustrated in FIG. 3, the 2D / 3D processing unit 130 includes a switch unit 131, a 3D → 2D conversion unit 132, a 2D → 3D conversion unit 133, and a 3D processing unit 134.

  The switch unit 131 converts the video supplied from the video processing circuit 108 and the OSD generation unit 106 based on the control signal supplied from the CPU 118 (1) LCD controller 109, (2) 3D → 2D conversion unit 132, ( 3) Supply to any of the 3D processing unit 134 and (4) 2D → 3D conversion unit 133.

(3D → 2D conversion unit 132)
The 3D → 2D conversion unit 132 converts the video (image) for stereoscopic display into the video (image) for flat display. For example, when the stereoscopic display video is a side-by-side video, the 3D → 2D conversion unit 132 divides each image constituting the video into left and right images, thereby left-eye images and right-eye images. Are extracted, and one of the left-eye image and the right-eye image is stretched in the horizontal direction to generate a flat display video. Further, when the stereoscopic display video is a top-and-bottom video, the 3D → 2D conversion unit 132 divides each image constituting the video vertically into two parts, whereby the left-eye image and the right-eye image are displayed. The image for the plane display is generated by extracting the image for use and stretching either one of the image for the left eye or the image for the right eye in the vertical direction.

(2D → 3D conversion unit 133)
The 2D → 3D conversion unit 133 converts the video (image) for flat display into a pseudo video (image) for stereoscopic display. For example, the 2D → 3D conversion unit 133 generates a right-eye image and a left-eye image from each image constituting a flat display image, and the image can be stereoscopically displayed by the side-by-side method or top-and-bottom from the images. Is generated.

(3D processing unit 134)
The 3D processing unit 134 extracts a right-eye image and a left-eye image from a stereoscopic display video (image), converts the images into a predetermined aspect ratio, and then performs a time-division method on the LCD controller 109. Are alternately supplied. For example, when the stereoscopic display video is a side-by-side video, the right-eye image and the left-eye image are extracted by dividing each image constituting the video into left and right parts, and the images are displayed. Is stretched in the horizontal direction, and then alternately supplied to the LCD controller 109 in a time-sharing manner. When the stereoscopic display video is a top-and-bottom video, the images constituting the video are divided into two parts in the vertical direction to extract a right-eye image and a left-eye image. Are stretched in the vertical direction, and then alternately supplied to the LCD controller 109 in a time division manner.

(Specific processing flow of the 2D / 3D processing unit 130 based on the control signal)
Hereinafter, specific processing of the 2D / 3D processing unit 130 when a control signal is supplied from the CPU 118 will be described.

(Step S101)
First, the 2D / 3D processing unit 130 identifies a control signal supplied from the CPU 118 and identifies whether the control signal is S_3DSBS, S_3DTAB, S_2DORG, S_2D3D, or S_O.

(Step S102)
When the control signal is any one of S_3DSBS and S_3DTAB, the 2D / 3D processing unit 130 switches the switch unit 131 to thereby target video (image) supplied from the video processing circuit 108 and the OSD generation unit 106. Is supplied to the 3D processing unit 134. The 3D processing unit 134 generates the video for time division display by performing the above-described processing on the target video (image), and supplies the video to the LCD controller 109.

(Step S103)
When the control signal is S_2D3D, the 2D / 3D processing unit 130 switches the switch unit 131 so that the target video (image) supplied from the video processing circuit 108 and the OSD generation unit 106 is converted from 2D to 3D. To the unit 133. The 2D → 3D conversion unit 133 performs the above-described processing on the target video (image), thereby generating a pseudo stereoscopic display video.

(Step S104)
In step S103, the 3D processing unit 134 performs the above-described processing on the pseudo stereoscopic display video (image) processed by the 2D → 3D conversion unit 133, thereby performing time-division display. A video is generated and supplied to the LCD controller 109.

(Step S105)
When the control signal is S_2DORG, the 2D / 3D processing unit 130 determines whether or not the target video (image) supplied from the video processing circuit 108 and the OSD generation unit 106 is a stereoscopic display video (image). Is determined.

(Step S106)
When the target video (image) is a video (image) for stereoscopic display (Yes in step S105), the 3D → 2D conversion unit 132 performs the above-described processing on the target video (image) for planar display. Are generated and supplied to the LCD controller 109.

(Step S107)
When the target video (image) is not a stereoscopic display video (image) (No in step S105), the 2D / 3D processing unit 130 supplies the target video (image) to the LCD controller 109 as it is.

(Step S108)
When the control signal is S_O, the 2D / 3D processing unit 130 supplies the target video (image) to the LCD controller 109 as it is.

  As described above, the 2D / 3D processing unit 130 performs the above-described processing based on the control signal from the CPU 118, thereby performing the video (image) after the processing specified by the identifier included in the file name. It can be displayed on the LCD 110.

  Thereby, it is possible to switch between flat display and stereoscopic display for each file without changing the extension of the video (image) file. In addition, since the 3D TV 1 can perform planar display and stereoscopic display using the same video (image) file in the data format (in the above example, “mpg” for video and “jpg” for image), There is no need to separately support the extension for stereoscopic display and the extension for flat display. In other words, there is no need to introduce a new extension for the image file for stereoscopic display. In addition, since a stereoscopic display video (image) file and a flat display video (image) file can be decoded by the same decoding method and then displayed by the respective display methods, the flat display video There is no difference in texture, roughness, or the like that may occur due to the difference in data format between (image) and stereoscopically displayed video (image). Therefore, the user can clearly recognize the difference in display effect between the flat display and the stereoscopic display.

<Modification>
In the above description, the CPU 118 refers to the identifier included in the file name of the video (image) file and controls the 2D / 3D processing unit 130 to perform the process specified by the identifier. Although described, the present embodiment is not limited to this.

  For example, when the 3D TV 1 acquires a video (image) file from the BD drive 102 or when acquiring a video (image) file via the Ethernet I / F 115 and the USB I / F 121, the 3D TV 1 A directory name (folder name) of a directory (folder) in which a video (image) file is stored is acquired in association with the video (image) file, and an identifier included in the acquired directory name (folder name) is referred to. The 2D / 3D processing unit 130 may be controlled to perform the process specified by the identifier.

  More specifically, for example, when the CPU 118 acquires a video (image) file stored in the USB memory via the USB I / F 121, the video (image) file is stored in the USB memory. The folder name of the existing folder is acquired in association with the video (image) file, the identifier included in the folder name is referred to, and the 2D / 3D processing unit 130 performs processing specified by the identifier. It can also be set as the structure controlled to.

  6A to 6E show the file name of the video (image) file acquired by the 3D TV 1 from the USB memory via the USB / I 121 and the video (image) file stored in the USB memory. (A) shows a case where the folder name does not include an identifier, (b) shows a case where the folder name contains an identifier “2DORG”, and (c) shows When the folder name includes the identifier “2D3D”, (d) indicates that the folder name includes the identifier “3DSBS”, and (e) indicates the case where the folder name includes the identifier “3DTAB”. Show.

  When displaying the image files “PhotoSample1.jpg” and “VideoSample1.mpg” included in the folder illustrated in FIG. 6A, the CPU 118 supplies the control signal S_O to the 2D / 3D processing unit 130. . When displaying the image files “PhotoSample2.jpg” and “VideoSample2.mpg” included in the folder shown in FIG. 6B, the CPU 118 supplies the control signal S_2DORG to the 2D / 3D processing unit 130. . When displaying the image files “PhotoSample3.jpg” and “VideoSample3.mpg” included in the folder shown in FIG. 6C, the CPU 118 supplies the control signal S_2D3D to the 2D / 3D processing unit 130. . When displaying the image files “PhotoSample4.jpg” and “VideoSample4.mpg” included in the folder shown in FIG. 6D, the CPU 118 supplies the control signal S_3DSBS to the 2D / 3D processing unit 130. . When displaying the image files “PhotoSample5.jpg” and “VideoSample5.mpg” included in the folder shown in FIG. 6E, the CPU 118 supplies the control signal S_3DTAB to the 2D / 3D processing unit 130. .

  Since the processing performed by the 2D / 3D processing unit 130 supplied with each control signal has already been described, the description thereof is omitted here.

  As described above, when the 3D TV 1 acquires the video (image) file, the 3D TV 1 acquires the directory name (folder name) of the directory (folder) in which the video (image) file is stored. Instead of referring to the file name, the identifier included in the directory name (folder name) of the directory (folder) is referred to, and the 2D / 3D processing unit 130 performs processing specified by the identifier. Can be controlled to do.

  Thereby, it is possible to switch between planar display and stereoscopic display for each directory (for each folder) without changing the extension of the video (image) file. In addition, since the 3D TV 1 can perform planar display and stereoscopic display using the same video (image) file in the data format (in the above example, “mpg” for video and “jpg” for image), There is no need to separately support the extension for stereoscopic display and the extension for flat display. In other words, there is no need to introduce a new extension for the image file for stereoscopic display. In addition, since a stereoscopic display video (image) file and a flat display video (image) file can be decoded by the same decoding method and then displayed by the respective display methods, the flat display video There is no difference in texture, roughness, or the like that may occur due to the difference in data format between (image) and stereoscopically displayed video (image). Therefore, the user can clearly recognize the difference in display effect between the flat display and the stereoscopic display.

  Also, in this modification, video (image) files can be managed for each display method, so even if video (image) files of various display methods exist, the user can Since video (image) files can be easily managed, convenience for the user is increased.

  When the video (image) file is managed by a hierarchical directory structure, for example, the directory 2 exists under the directory 1, the directory 3 exists under the directory 2, and the video (image) file exists. Is stored in the directory 3, the CPU 118 refers to the identifier included in the directory name of any one of the directories 1 to 3, and the video (image) according to the display mode designated by the identifier. ) It is also possible to display a video (image) represented by a file.

  Further, the CPU 118 may be configured to refer to identifiers included in both the directory name and the file name. For example, when an image file whose file name is “Photo_SBS_Sample.jpg” and an image file whose file name is “Photo_TAB_Sample.jpg” are stored in the directory whose directory name is “Directory_3D_Sample”, The CPU 118 refers to the identifier “3D” included in the directory name “Directory_3D_Sample” to identify that the image file stored in the directory is to be stereoscopically displayed, and the file name “Photo_SBS_Sample.jpg”. By identifying the identifier “SBS” included in the image file, it is identified that the image file “Photo_SBS_Sample.jpg” should be displayed by the side-by-side method in the 3D display, and is included in the file name “Photo_TAB_Sample.jpg” By referring to the identifier “TAB”, the image file “Photo_TAB_Sample.jpg” It is good also as a structure which identifies that it should display by a top and bottom system among displays.
