Abstract
For obtaining both still and moving images in satisfactory manner in an image pickup device, in addition to a circuit for generating a moving image, frame recursive filters,and an interface circuit,are provided for generating a still image. Wide-band color signals R, G, B generated from the signals obtained from the CCD are subjected to a filtering process in the frame recursive filters,and the image retained in the filters,as a result of the filtering process is released as a still image under the control by the interface circuit,Thus the still and moving images can be generated respectively according to the required characteristics, without color blotting or color aberration and without deterioration in the color reproducibility and in the S/N ratio.
