ABSTRACT:
An image sensing apparatus of the invention has a photoelectric conversion device including a plurality of photoelectric conversion elements, arranged in a matrix pattern, and output terminals for simultaneously reading out signals of a plurality of lines.
A control circuit simultaneously reads out the signals of the lines of the photoelectric conversion device.
An edge signal generating circuit receives the signals of the lines, operating them and generating an edge-corrected signal.
A switch switches the connection between the output terminals of the photoelectric conversion device and the input of the edge signal generating circuit, in correspondence with a change in the combination of the lines to be read out. The apparatus has a simple configuration and can perform signal processing such as edge correction.
