ABSTRACT:
An image sensing apparatus including an image sensing device for receiving a light signal, performing a photoelectric conversion, and generating image information. The device also includes a first type semiconductor substrate, and a second type semiconductor layer formed on the first type semiconductor substrate. In addition, there is provided a light receiving portion formed on the second type semiconductor layer. This portion receives a light signal, performs a photoelectric conversion, and generates image information. Moreover, there is control circuitry for controlling the image sensing device such that image information is output repeatedly once each reading period nT (where n is an integer equal to or greater than two and T is a field period of a standard television signal). Information corresponding to a partial interval T1 within the reading period nT is carried to the first type semiconductor substrate. There is also provided altering circuitry for altering the length of the partial interval T1.
