Abstract:
1. A moving picture encoding apparatus comprising: a skip number control section which controls a skip number between frames to be encoded; a quantization scale control section which controls a quantization scale indicative of a degree of quantization; an encoding section which encodes a moving picture, by selectively using one of an inter-coding and an intra-coding, on the basis of the quantization scale determined by the quantization scale control section and the skip number determined by the skip number control section; a code amount detection section which calculates a code amount of a frame encoded by the encoding section; a storage section which stores the quantization scale with which the encoding section encodes by the inter-coding, the code amount of the inter-coding calculated by the code amount detection section, the quantization scale with which the encoding section encodes by the intra-coding, and the code amount of the intra-coding calculated by the code amount detection section; and an encoding setting section which sets the encoding to be used by the encoding section to the intra-coding, if the skip number determined by the skip number control section has reached at least a predetermined first threshold while the encoding section is encoding by the inter-coding, and if the ratio of a product of a mean value of the quantization scale and the code amount of the inter-coding stored in the storage section to a product of a mean value of the quantization scale and the code amount of the intra-coding stored in the storage section is greater than a predetermined second threshold.
