摘要： A signal separation unit (101) separates an input picture made up of component pictures of RGB, each of which has an equal number of pixels as the input picture, into three component pictures, and outputs the three component pictures. Each of coding units (102 to 104) codes one of the component pictures into an intra-picture prediction coded picture or an inter-picture prediction coded picture, and outputs a bit stream corresponding to the component picture. A bit stream multiplexing unit (105) multiplexes three bit streams outputted from the three coding units into one bit stream, and outputs the bit stream. Each of the coding units (102), (103) and (104) determines a prediction method for the component picture at the time of coding.

摘要： The present invention enables to control the encoding of film grain information without adversely affecting the over-all coding efficiency of the encoding process of video data. For this purpose, a control of the size of the quantization interval for the lowest transform coefficient values is separated from a control of fitting the quantization interval and the quantized value to a probability distribution of the transform coefficient values. This is accomplished by providing a dead-zone parameter to be taken into account by the quantization process and the de-quantization process.

摘要： Provide is an image decoding apparatus which reliably prevents deterioration of the image quality of decoded images which have been previously coded. An image decoding apparatus (200) includes: an inverse quantization and inverse orthogonal transform unit (220) and an adder (230) which decode a coded image included in a coded stream (Str) to generate a decoded image (Rc); an entropy decoding unit (210) which extracts cross-correlation data (p) which indicates a cross-correlation between the decoded image (Rc) and an image which corresponds to the decoded image and has not yet been coded; and an adaptive filter (240) which computes a filter parameter (w) based on the extracted cross-correlation data (p), and performs a filtering operation on the decoded image (Rc) according to the filter parameter (w).
