ABSTRACT:
An encoding section can perform moving picture compression processes by intra-coding and inter-coding. In accordance with an instruction from a code production amount control section, the encoding section divides an input VOP to MBs according to one of the moving picture compression processes by intra-coding and inter-coding, and subjects the divided MBs to encoding processing. A code production amount count section counts the code amount of a produced bit stream. A quantization scale mean value calculation section accumulates the quantization scale instructed by the code production amount control section, and calculates a mean value of the quantization scale for each VOP. The code production amount control section switches the encoding process to be carried out by the encoding section to the intra-coding process, on the basis of the code production amount, the mean value of the quantization scale and the frame skip number.
