Abstract
A method for image correction and image projection apparatus using the same are provided, where the image projection apparatus scans a projection light beam on a projection plane to form an image. The image correction method includes the following steps. A plurality of projection points of the projection light beam on the projection plane are sampled to define a projection coordinate system. An image projection area is defined on the projection coordinate system. The projection light beam is moved to scan on the projection plane and projected to the projection points sequentially. Whether the projection point is located in the image projection area is determined. When the projection point is located in the image projection area, a corrected image information is provided to the projection point.
