ABSTRACT:
An image coding apparatus includes a still frame coding judgment unit for judging whether a target frame to be coded is a still frame or not from a difference value between the target frame and an immediately previous reference frame, and a quantization parameter control unit for performing control of a quantization parameter value to be used for coding, on an initial one frame at which an image starts to come into a standstill, wherein the initial frame is subjected to coding with less coding error as compared with coding for other frames.
