Abstract
An image encoding method includes a step in which image data of components other than image data of components representing the transparency of an image is encoded from among image data of components which includes image data of components representing the transparency of the image, and a step in which an image file is created from image data of components encoded in the encoding step and image data of components other than image data of components encoded in the encoding step. Accordingly, because image data of components representing the transparency of the image is not encoded in the encoded image file, the image shape can be recognized. Moreover, because the image data of the remaining components is encoded, the security of the details of the image data can be maintained.
