Abstract
An information processing apparatus capable of specifying a reflection surface cheaply and accurately. A connected image forming apparatus generates a signal having first and second levels on the basis of information about reflection surfaces of a polygon mirror so that a period of the first level corresponding to a predetermined reflection surface becomes longer than that corresponding to the other reflection surfaces. The information processing apparatus detects a first timing at which the signal changes to the first level from the second level and a second timing at which the signal changes to the second level from the first level, specifies the reflection surface based on a period from the first timing to the second timing that is detected first after elapsing a first period from the first timing, and corrects the image data corresponding to the reflection surface according to the surface information and correction data.
