ABSTRACT:
A sheet image scanner of the present invention has plural image sensors to output electric signals by detecting optical image data that are obtained by applying a light from a light source to documents, amplifiers to amplify outputs from the plural image sensors, and a peak detection processing unit to detect a peak value of sensitivity of at least one of the plural image sensors and set a gain value for each of amplifiers for the plural image sensors using the detected peak value.
