Abstract
An image projection device includes an optical correction unit, a panel and a lens. The optical correction unit is utilized for receiving an image and pre-distorting the image to generate a pre-distorted image according to pre-distortion parameters. The panel is coupled to the optical correction unit, and is utilized for receiving and projecting the pre-distorted image. The lens is positioned in front of the panel, where the pre-distorted image projected from the panel passes through the lens, and the pre-distortion parameters correspond to distortion effects caused by the lens.
