Abstract

[PROBLEMS] To provide a video image encoding or decoding system and video image encoding or decoding method enabling avoidance of failure phenomenon while low power consumption is achieved. [MEANS FOR SOLVING PROBLEMS] This invention comprises required computational complexity calculating means (2) for calculating computational complexity required to encode or decode a predetermined frame, operation determining means (3) for calculating the operating power supply voltage, substrate bias voltage and operating frequency with which the encoding or decoding is possible within a time Te previously allocated for encoding or decoding the predetermined frame. During the time Te, a processor (1) encodes or decodes the predetermined frame with the calculated constant operating frequency, operating power supply voltage, and substrate bias voltage. The invention further comprises failure avoiding means for avoiding a failure phenomenon that occurs when the required computational complexity calculated by the required computational complexity calculating means is smaller than the computational complexity actually required.
