摘要：<p>PROBLEM TO BE SOLVED: To generate a compressed image that can be restored to an original image. SOLUTION: Pixel values of a host image are repetitively updated in an initial state (1st to 4th update numbers) and when a change quantity of an error is smaller than a prescribed 1st threshold value, a coefficient is updated (5th update number). When the pixel values are repetitively updated further (6th to 9th update numbers) and the change quantity of the error is again smaller than the prescribed 1st threshold value, the coefficient is updated (10th update number). Furthermore, when the pixel values are being updated and the change quantity of the error is smaller than a 2nd threshold value, updated host image data that are updated at that time are outputted.</p>
