Abstract
Provided are a TSM rate-distortion optimizing method, encoding method and device using the same, and an image processing apparatus. The TSM rate-distortion optimizing method includes calculating a cost of each intra-prediction mode with respect to a block to be encoded using a sum of absolute values of differences between original pixels and reference pixels; selecting candidate modes of the intra-prediction modes according to the cost; calculating a TSM (Transform Skip Mode)-based rate-distortion cost according to the candidate modes; and comparing rate-distortion costs of the candidate modes and deciding a mode to be used for intra-prediction of the block.
