Abstract
Abstract In order to display a high resolution still image by using a single image sensor type image sensing apparatus employing a single relatively low resolution CCD, an image of an identical object is taken four times in short time intervals. Each time the image sensing operation is carried on, it is controlled that an imaging position on a photo-sensing surface of the CCD is shifted by one pixel. Color signals of the plurality of color components which are obtained as above are stored in a predetermined areas in an image memory by each color component. After four image sensing operations are completed, the color signals are read from the image memory, and the final color signals or brightness signals are generated based on the read color signals, and displayed on a display.
