Abstract
In general, according to one embodiment, a scanner includes an original document stand, a pressure plate, a carriage, an image sensor, an amplification unit, and a processor. The processor turns on the light source during closing the pressure plate, detects a sheet size in a second direction perpendicular to the first direction, causes a light amount of the light source at the time of detecting the sheet size to be less than a light amount of the light source at the time of the image reading, and performs a first process of causing a first gain of the amplification unit at the time of detecting the sheet size to be greater than a second gain of the amplification unit at the time of the image reading.
