Abstract
An image forming apparatus that displays an image, includes: a scanning section that scans light from a light source in a main scanning direction and a sub-scanning direction orthogonal to the main scanning direction, as drawing sine waves; a detecting part that detects a change in a position of the scanning part in the main scanning direction and a change in a position of the scanning part in the sub-scanning direction; a phase difference comparator that detects a phase difference and a frequency ratio between the main scanning direction and the sub-scanning direction, based on the change in the position of the main scanning direction and the change in the position of the sub-scanning direction; and an image data generation part that estimates a scanning trajectory of the scanning part based on the phase difference and the frequency ratio, and generates pixel data corresponding to the scanning trajectory.
