Abstract
A parallel synchronous scaling engine for multi-view 3D display and a method thereof are provided, wherein selection and combination calculation are provided to an interpolation pixel window, then interpolation calculation is provided to a combined interpolation pixel window of a combined view field, calculation results are directly displayed on a display terminal. That is to say, interpolation is originally provided before stereoscopic pixel rearrangement, which is now improved, in such a manner that screening and combination of pixel points is provided before interpolation calculation. According to the present invention, computation and memory resource is greatly saved. The method is suitable to be implemented by hardware, for satisfying various numbers of viewpoints and interpolation algorithm, and being compatible with multi-view 3D display with the integrated and floating-point pixel arrangement, wherein the computation resource does not need to be increased with increasing of the viewpoints.
