ABSTRACT:
An image sensing apparatus with an image sensor which comprises a plurality of sensors (47) each provided on each of pixel (37) forming a photo-receptive area (36), the sensor generating an electric signal in response to brightness of incident light from a subject; and a plurality of dual-function CCDs (40A-40H) for signal storage and read-out connected to the sensors, respectively, the dual-function CCDs each comprising a plurality of charge storage elements. The dual-function CCDs are of substantially linear shape, elongated over two or more of the pixels, and arranged parallel to each other. During an image sensing process, electric signals generated in the sensors of the pixels are transferred parallel in one direction by the plurality of dual-function CCDs, whereby the electric signals generated in the sensor are stored in the charge storage elements of the dual-function CCDs. During a signal read-out process, the electric signals stored in the charge storage elements of the dual-function CCDs are transferred parallel in the same direction as in the image sensing process, whereby the electric signals are read out of the photo-receptive area.
