Abstract
A method of adjusting an image parameter and a scanning apparatus are provided. The method includes the steps of: scanning a standard picture and moving the standard picture by an actual distance; generating a pulse signal corresponding to the actual distance; getting a standard distance corresponding to the pulse signal; and comparing the actual distance with the standard distance and adjusting a default pulse frequency. When the actual distance is shorter than the standard distance, the default pulse frequency is increased. When the actual distance is longer than the standard distance, the default pulse frequency is decreased.
