Definitions

• 3D image technologies There are two types of 3D image technologies; technology for generating video data with 3D images and technology for generating 3D images from video data generated with 2D images. These two technologies are being researched and developed together.
• FIG. 7 is a module view of a server transmitting metadata for disk management, according to an embodiment of the present invention.
• FIG. 9 is a flowchart for describing a method of displaying images, according to an embodiment of the present invention.
• metadata for generating a depth map includes depth information, which is information for providing depth to frames.
• the depth information is information to convert 2D images to 3D images by providing depth to frames, and includes depth information for background and depth information for objects.
• FIGS. 3A and 3B are diagrams for describing depth information included in the metadata for generating a depth map, that is, the metadata shown in FIG. 1.
• FIG. 3A is a diagram for describing a depth provided to an image
• FIG. 3B is a diagram for describing a depth provided to an image when the image is viewed from a side.
• the image processing device 200 is a device for decoding video data, generating 2D video images, and either converting the 2D video images to 3D images by using metadata for disk management and transmitting the 3D images to the image displaying device 300 or transmitting the 2D video images to the image displaying device 300 without conversion.
• the image processing device 200 may be a DVD player, a set-top box, or other similar devices.
• the image processing device 200 may generate graphic information to indicate that the images transmitted to the image displaying device 300 are 3D images.
• the graphic information may be emoticons, texts, images, etc.
• the image processing device 200 overlays generated graphic information on the 3D images and transmits the 3D images to the image displaying device 300.
• the image processing device 200 may generate a control signal instructing the image displaying device 300 to switch to the 2D image displaying mode and transmit the control signal to the image displaying device 300 such that the image displaying device 300 can display 2D images.
• a CEC line transmits control data transmitted for controlling devices using HDMI.
• the video image buffer 250 and the graphic information buffer 270 temporarily store video images and graphic information, respectively.
• STC presentation time stamp
• the video image buffer 250 and the graphic information buffer 270 transmit the video images and the graphic information to a blender 280.
• the blender 280 overlays the video images and the graphic information and transmits them to the image displaying device 300.
• the disk management metadata processing unit 220 controls the graphic information processing unit 260 to generate graphic information indicating that the images are 3D images.
• the graphic information processing unit 260 transmits the generated graphic information to the graphic information buffer 270.
• the unit 220 controls the graphic information processing unit 260 to generate graphic information indicating whether the images to be displayed are 2D images or 3D images, generates a mode switching control signal for changing the image displaying mode of the image displaying device 300, and transmits them to the image displaying device 300.
• the depth map buffering unit 640 temporarily stores a depth map corresponding to the background transmitted from the filtering unit 630.
• the depth map buffering unit 640 combines the depth map corresponding to the background and the depth map corresponding to the object and updates a depth map corresponding to a frame.
• the depth map buffering unit 640 updates a depth map by sequentially overlaying depth maps corresponding to the plurality of objects.
• the depth map buffering unit 640 transmits the completed depth map to a stereo rendering unit 650.
• FIGS. 8A and 8B illustrate images, on which graphic information is overlaid, displayed by the image displaying device 300.
• FIG. 9 is a flowchart for describing a method of displaying images, according to an embodiment of the present invention.
• the image processing device 200 generates 2D images by decoding video data, and determines whether the image displaying device 300 is a device capable of displaying both 2D images and 3D images (operation 910). If the image displaying device 300 is capable of displaying 2D images only, the image processing device 200 transmits 2D images to the image displaying device 300 (operation 980).
