Abstract
In the case where the code generation volume that the data occupancy rate in the buffer of the image decoding apparatus is smaller than the first, second or the third threshold value corresponding to the first, second or the third image currently being coded from among the first, second and third threshold values of the data occupancy rate set corresponding to the first image to be intra-coded, the second image to be directionally predictive coded and the third image to be bidirectionally predictive coded respectively, the coding processing on the first, second or the third image presently being coded will be stopped. Further, the coding controlling unit calculates the occupancy rate in a VBV buffer by a VBV buffer occupancy rate calculating unit to obtain the coding difficulty representing the difficulty of the coding of image flowing to the image of which the coding is complete by a coding difficulty calculating unit , and stops the coding of image to be coded next in the case where the VBV buffer occupancy rate is smaller than the predetermined occupancy rate determining threshold value and also the coding difficulty matches with the predetermined standard, when an image has been coded.
