<p>An image coder and an image decoder which can eliminate the deterioration of the quality of image at the time of encoding an image by deforming a shape information area extending over the inside and outside of an image frame based on the shape of an image information area during the course of the irreversibly encoding processing of a shape image, or expanding the circumference of the image information area by interpolation, so that all preceding shape information areas are included in the circumference before the processing.</p> |
