The present invention improves the encoding efficiency, image quality, resolution, and the like of an input image having a special property, for example, an image input from a special camera. The input image is sliced according to a recognized shape and divided into blocks having a size according to a pixel density or an image resolution. Then, an object in the image is defined using a parameter including the numbers of the sliced images and the amounts of shift of the sliced images from a reference position, and the respective blocks are encoded using the movement of the object. Further, when a partial image is cut out from a base image, encoded, and then transmitted, a processing load in the encoding processing is reduced by encoding the partial image making use of preprocessing data.
