Abstract
In an image processing apparatus, an encoding unit encodes a processed image; a determining unit determines whether a reference pixel has been subjected to the image processing; and a decoding unit decodes, when the determining unit determines that the reference pixel has been subjected to the image processing, a piece of rectangular block code data of a rectangular block thereby acquiring a second decoded image. The encoding unit refers to, when the determining unit determines that the reference pixel has been subjected to the image processing, the processed image and encodes the second decoded image.
