Abstract
An image reading device includes: a light-source adjusting device, a storage, a first converting device and a determining device. The adjusting device adjusts brightness of the light source to the brightness corresponding to the one of a plurality of reading modes. The storage stores an reference adjusting value and converting information, the reference adjusting value being adjusted in a state where external light is not incident on a platen, the converting information being for converting the reference adjusting value of the reference mode into the reference adjusting value of another reading mode. The first converting device refers to the converting information and converts the reference adjusting value into the value of the selected reading mode. The determining device determines presence or absence of external light incident on the platen, comparing the converted reference adjusting value with the light-source adjusting value adjusted by the adjusting device.
