Coded deformation decrease device, coded deformation decrease manner and program for that

摘要

Topic The coded deformation decrease device which held down the decrease of picture quality without using the information of encoding, is offered. SolutionsCoded deformation decrease section 8 of execution configuration, has with the around pixel state decision section and the filter strength decisive section and the deringingu treatment section. As for the around pixel state decision section, decoding the graphics data which is encoded, it decides the flat part around the filtering target pixel in the graphics data which can and the state of the edge. The filter strength decisive section decides the filter strength which is used for filter treatment according to the state of the aforementioned flat part and the aforementioned edge. The deringingu treatment section treats deringingu making use of the filter strength which is decided. Choice figure Drawing 2
