As shown in Figure 4, this display packing comprises:
Common 2D signal is converted into 3D three-dimensional signal by step 101,2D/3D transducer.
The general principle that 2D turns 3D function is the scene by analyzing 2D, and the close shot image in the middle of scene is carried out sketching the contours and giving prominence to, is undertaken rearmounted simultaneously by distant view image, such as, personage etc. are preposition, and background environment and object carry out rearmounted; Further, the preceding part of same object is preposition, and posterior part is rearmounted, thus real-time implementation 2D image is converted to 3D effect.
3D three-dimensional signal calculates and is separated into the signal corresponding with each display screen by step 102, depth of field processing and control module, in the present embodiment for the calculating of 3D three-dimensional signal is separated into the first signal and secondary signal by depth of field processing and control module.
Depth of field processing and control module adopts spaced pixels image-forming principle, is calculated by 3D three-dimensional signal and is separated into the signal corresponding with each display screen.The first signal and secondary signal is separated in the present embodiment for being calculated according to the close shot distant view of required 3D stereo display result by 3D three-dimensional signal.
Further, the first display screen is divided into the first pixel cell and the second pixel cell, the first pixel cell display, and the second pixel cell does not show; Second display screen is divided into the 3rd pixel cell and the 4th pixel cell, and the 4th pixel cell display, the 3rd pixel cell does not show.
Such as, as shown in Figure 5, after calculating and being separated, 1 to 9 picture element signal is separated, and the first display screen receives 1,3,5,7 and 9 picture element signals, i.e. the first signal; Second display screen receives 2,4,6 and 8 picture element signal, i.e. secondary signals.Further, the first display screen receives only close shot picture signal, then concrete processing method has following three kinds:
Method one: if in former 3D rendering signal, 1 to 9 picture element signal is close shot picture signal, then 1,3,5,7,9 picture element signals of the first display screen are the respective pixel signal of former 3D rendering signal, distribute to the first pixel cell on display screen; Rest of pixels on first display screen, without picture signal, is the second pixel cell, is light transmission state when actual displayed, allows the display image of second display screen to pass through; Preferably, the first pixel cell and described second pixel cell spaced apart on the first display screen.
