Abstract
A technique that can realize acquisition of a proper white reference value in shading correction is provided. It includes plural line sensors arranged at different positions from each other in a sub-scanning direction and configured to read reflected light from a reading target surface, guided by a scanning optical system that moves in the sub-scanning direction, and a reading control unit configured to control image reading timing in each line sensor so that, when reading a predetermined white reference board by the plural line sensors in order to perform shading correction, the plural line sensors have substantially the same reading area on the white reference board.
