The similarity section consists of consecutive unit sections, inclusive of the target unit section, which each have similar section feature data. The judgment unit calculates a priority of each boundary indicated by one or more of the pieces of boundary information and judges whether the boundary is a scene change point based on the priority.

Abstract: In order to enhance the picture quality of a detected area, the present invention provides a video coding apparatus. In the apparatus, a reliability indicative of the degree of coincidence of an area detected by an important area detecting section with a real important area is calculated, and a coding parameter calculating section calculates a coding parameter to be set to the detected area according to the reliability, thereby controlling the picture quality of the detected area. Consequently, a whole image has a coding bit amount which does not break the restrictions of a transmission bit rate, and a larger coding bit amount is assigned to the important area so that a picture quality thereof can be improved and a visibility can be enhanced. In addition, the picture quality is more enhanced if a probability that the detected area might be an important area is higher.

Data coded by the intra-frame coding mode existing in the first data sequence is transformed to the second data sequence.
