Abstract
Before reading of a document, an image processing control portion makes an image reading portion perform pre-scanning operation, which is scanning operation performed with a document cover open without a document placed on a placement surface, and checks the incident condition of external disturbance light on the image sensor. If it is judged that the incident condition is a predetermined state, the image processing control portion makes a control device perform a countermeasure process to make the room dimmer than it currently is.
