Apparatus and method for performing geometric transformations on an input image

摘要

An image transforming apparatus comprising a means for holding an input image signal, a means for holding geometric parameters for the image signal in a photographing mode, a processing means for geometrically transforming the image signal by the use of such geometric parameters, and a means for outputting the image signal transformed geometrically by the processing means. There is also provided a method of transforming an input image by employing the above apparatus to realize a tilting process and a depth-effect emphasizing process for the image obtained from a video camera, an electronic still camera or the like.
