Abstract

See full text

An image reading apparatus includes: a reading unit configured to read an image of an original and output an image signal; and a white reference plate to be used for shading correction. The image reading apparatus drives the reading unit with maximum power consumption for a predetermined time period and thereafter drives the reading unit with reduced power consumption. The image reading apparatus causes the reading unit with reduced power consumption to read the white reference plate and generates shading data to be used for the shading correction. After that, the image reading apparatus causes the reading unit to read an original and corrects a reading result of the original based on the shading data.
