ABSTRACT:
An image reading method and apparatus includes detecting an optimal position of a slot of a light intercepting plate by reading an output level from a light sensor which receives light passing through the slit, moving the light intercepting plate to an optimal slit position in accordance with the read output level, and correcting any deviations in a scanning direction based on the amount the light intercepting plate is moved.
