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： A video coding method enables reduction in the decrease in the efficiency of coding a video and enhancement of the image quality of the resulting decoded video. The video coding method includes predicting a video signal to generate a prediction signal; calculating, as a prediction error signal, the difference between the video signal and a prediction signal; and generating a reconstructed video signal by reconstructing the video signal based on the prediction signal and the prediction error signal. The video coding method also includes determining filter data items that are used to filter each of at least two of the prediction signal, the prediction error signal, and the reconstructed video signal; and coding the determined filter data items based on the cross correlations between the determined filter data items.
