  • Method of implementing intra prediction computation applied to H.264 digital video coding and device
    Patent number: 8594198
    Abstract: The present invention provides a method of implementing an intra prediction computation applied to the H.264 digital video coding and a device. The method according to present invention of implementing the intra prediction computation applied to the H.264 video coding comprises selecting an image block to be intra-predicted and extracting the neighboring pixel values of said block; determining the prediction mode of said block, and perform first adding operation on said neighboring pixel values when the prediction mode is one of Diagonal_Down_Left, Diagonal_Down_Right, Vertical_Right, Horizontal_Down, Vertical_Left, and Horizontal_Up; performing first shifting operation and second adding operation on the result of first adding operation respectively; performing second shifting operation on the result of second adding operation; selecting a corresponding value to output from the results of first and second shifting operation according to said prediction mode and size of block.
