ABSTRACT:
In an image sensing apparatus, an array of two-dimensional matrix of photosensitive devices is used to detect an image. Each photosensitive device comprises a photosensor accumulating carriers when exposed to a light, control terminals, and an output terminal. A signal generator supplies a vector or a one-dimensional data to the control terminals in the array to output pixel data of the two-dimensional matrix, and the pixel signal is output through the output terminal. The control terminals of the photosensors arranged along each line are connected commonly, while the output terminals thereof arranged along each column are connected commonly. A controller supplies control signals to the control terminals. Then, pixel signal for columns designated by a control signal are output through an output circuit connected to the control terminals. Then, a partial region in the array including a region exposed by the light is determined according to the pixel signals, and data on the partial region is sent to the controller. Then, the controller supplies control signals in correspondence to the partial region. Then, correlation operation of the control signals with the amount of carriers in the photosensors are carried out while reading the pixel signals, and the pixel signals in the partial region is output.
