CA 2253979

An inputted analog color video signal is converted into a digital video signal by an analog-to-digital converting circuit 13, is then written into a transfer buffer 15, and is digitally processed. That is, with respect to a moving picture which is changed for each frame, black-and-white image data is extracted from the digital video signal stored in the transfer buffer 15, is temporarily stored in a WT buffer memory 21, and is displayed on a CRT. With respect to a still picture whose acceptance is designated at suitable timing while seeing the moving picture, color image data is extracted from the digital video signal stored in the transfer buffer 15, is temporarily stored in a CT buffer memory 28, and is displayed on the CRT.
