Definitions

  • the invention further relates to the above mentioned 3D source device, the 3D display signal and the 3D display device.
  • the invention relates to the field of transferring, via a high-speed digital interface, e.g. HDMI, three-dimensional image data, e.g. 3D video, for display on a 3D display device.
  • a high-speed digital interface e.g. HDMI
  • three-dimensional image data e.g. 3D video
  • the invention is also based on the following recognition. All legacy analog and digital display interface signals inherently are designed for directly generating display control signals, like the horizontal line synchronization pulses and frame sequences described above. Hence the signal itself dictates the timing and generation of the display control signals, whereas the function of each subsequent frame is implicit by its location in the signal.
  • the traditional display unit does not process the image data but strictly follows the display interface signal.
  • the inventors have seen that for 3D display signals there is a need for constituting the final 3D display control signals in the display device itself, because the various display type signals and viewer conditions and settings cannot be optimally achieved if the components of the 3D image data are combined, by the source device, in a predefined fixed way in the interface signal.
  • the new 3D display signal various components are transferred separately in frames of different frame types.
  • the process of detecting the different frame types and the process of combining the partial data structures, which takes place in the display device is still to be controlled by the transmitter source device.
  • the inventors provided the frame type synchronization indicator that is now included in the 3D display signal.
  • Fig. 1 shows a system for transferring three dimensional (3D) image data, such as video, graphics or other visual information.
  • a 3D source device 10 is coupled to a 3D display device 13 for transferring a 3D display signal 56.
  • the 3D source device has an input unit 51 for receiving image information.
  • the input unit device may include an optical disc unit 58 for retrieving various types of image information from an optical record carrier 54 like a DVD or BluRay disc.
  • the input unit may include a network interface unit 59 for coupling to a network 55, for example the internet or a broadcast network, such device usually being called a set-top box.
  • Image data may be retrieved from a remote media server 57.
  • a different 3D format is based on two views using a 2D image and an additional depth image, a so called depth map, which conveys information about the depth of objects in the 2D image.
  • the format called image + depth is different in that it is a combination of a 2D image with a so called "depth", or disparity map.
  • This is a gray scale image, whereby the gray scale value of a pixel indicates the amount of disparity (or depth in case of a depth map) for the corresponding pixel in the associated 2D image.
  • the display device uses the disparity, depth or parallax map to calculate the additional views taking the 2D image as input.
  • Adding stereo to video also impacts the format of the video when it is sent from a player device, such as a Blu-ray disc player, to a stereo display.
  • a player device such as a Blu-ray disc player
  • a stereo display In the 2D case only a 2D video stream is sent (decoded picture data). With stereo video this increases as now a second stream must be sent containing the second view (for stereo) or a depth map. This could double the required bitrate on the electrical interface.
  • a different approach is to sacrifice resolution and format the stream such that the second view or the depth map are interlaced or placed side by side with the 2D video.
  • Fig. 2 shows an example of 2D data and a depth map. The depth display parameters that are sent to the display to allow the display to correctly interpret the depth information.
