Image signal processing method, image signal processing device, image signal processing program and integrated circuit device

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.
