Using motion vectors and the occurrence of coefficient quantization levels to drive a noise removal image postprocessing

摘要

An image signal processing method, an image signal processing device and an image signal processing program are provided for performing post-processing, independently of the specification of a decoder. A coding parameter estimation portion estimates a quantization parameter, a picture type and a motion vector that were used for coding by using a decoded image entered from a decoding portion. The estimated quantization parameter or the like is sent to a post-processing portion. The post-processing portion performs the post-processing by using the entered quantization parameter, picture type and motion vector for eliminating block noise or mosquito noise.
