Abstract
Provided are an image processing apparatus and method whereby even if shape data representing the shape of an object in a moving image undergoes a major change temporarily, a frame that is to be corrected can be detected and corrected in ideal fashion and it is possible to execute moving-image coding that is outstanding both visually and in terms of coding efficiency. In one example, a moving image composed of a plurality of frames is acquired from a image input unit () and the background image of the moving image is acquired by a background image generating unit (). A background subtraction processor () extracts an object by comparing each of the frames constituting the moving image with the background image, and an abnormal-data discrimination unit () discriminates whether shape data representing the shape of the extracted object is abnormal or not. If the shape data is abnormal, a shape-data correction unit () corrects the shape data. An image-data correction unit () corrects a frame using the corrected shape data, and the corrected shape data and image data is coded by an encoder ().
