A Method Based on Rapidly Looking up Tables of Converting YCbCr to RGB in Video Decoder
Lin Dai · Modern Electronics Technique · 2007
RBG colour space,YCbCr colour space and the conversion between them are introduced in this paper.Look-up table method is used when converting YCbCr to RGB in order to improve the speed of converting,reduce calculation amount and advance the performance of video decoder.The time complexity and space complexity are considered in this paper.An experiment is given to demonstrate the efficiency of the optimization in the embedded media player software.
