An encoding controller (106) generates and outputs a current skip signal (SKi) to a switch circuit (108), and outputs a quantization parameter (Qp) for controlling a code amount after the encoding processing of a current VOP by an encoder (103) using a current scene change signal (SCi), to an encoder (106). The current scene change signal (SCi) is set on the basis of the current VOP, a previous scene change signal (SCi-1), and a previous skip signal (SKi-1).
