Abstract
An image captured from a camera is subjected to distortion correction processing performed in real time with high accuracy at low cost and is rendered as a smooth image. The image captured from the camera via a capture circuit is stored in a frame memory of a rendering memory unit, and is then subjected to image correction processing by a rendering processing unit. The rendering processing unit adds control points to the image based on distortion information stored in a correction information storing unit, and performs processing so that a shape of a mesh region formed when the control points of the image are connected to one another becomes square by moving the control points. This processing is corrected using, for example, a bilinear filter and the like.
