MOVING IMAGE PROCESSING METHOD AND PROCESSOR THEREFOR

摘要

PURPOSE: To prevent the degradation of image quality and the generation of block distortion in moving image software aiming at a special effect by positively using a noise pattern with low condensation. CONSTITUTION: The bit stream in conformity with an MPEG is generated by multiplexing the information on a noise pattern as the data of a user area on the compressed moving image data coded by an MPEG encoder 11. The moving image data that the compressed moving image in this bit stream is decoded by an MPE decoder 21 is composed with the noise pattern data based on the information on the noise pattern in the bit stream.
