Abstract
An inter-frame predicted error signal generation unit generates an inter-frame predicted error signal for selectively performing prediction between an input image signal of the current frame and a decoded image signal of the previous frame, and between the input image signal of the current frame and the image signal of the previous frame. A coding unit selectively codes the inter-frame predicted error signal generated by the inter-frame predicted error signal generation unit and the input image signal with high-efficiency compression. A statistical amount calculation unit calculates a statistical amount of the inter-frame predicted error signal generated by the inter-frame predicted error signal generation unit. Based on the statistical amount of the inter-frame predicted error signal calculated by the statistical amount calculation unit, a discrimination unit discriminates whether or not coding by the coding unit is to be performed. A transmission unit transmits a discrimination signal indicating that coding is not to be performed when the discrimination unit discriminates that coding by the coding unit is not performed.
