Abstract
A lens is provided for converging rays reflected from an object, and a line sensor is provided for receiving rays converged by the lens. The line sensor has a plurality of photoelectric conversion elements corresponding to predetermined pixels of one line. White level correction data are obtained for correcting a deviation of an output signal of each photoelectric conversion element from a standard value, and plane correction data is obtained for correcting unequal distribution of quantity of light dependent on the lens. An output signal of the line sensor is corrected with the white correction data and the plane correction data.
