Abstract
An image processing apparatus includes: a reading part for optically reading an image from an original image on a recording medium; a conversion part for converting the read-out image into a digital image; a first storage part for storing the digital image; an input part for inputting an instruction and a password number; an encoding part for transforming the digital image to an encoded image when an encoding process for the digital image is selected according to the instruction; a decoding part for transforming the digital image to a decoded image when a decording process for the digital image is selected according to the instruction, a second storage part for storing the encoded image in accordance with a memory address determined based on the password number when the encoding process is selected, and for storing the decoded image in accordance with the memory address determined based on the password number when the decoding process is selected, and an output part for outputting either the encoded image or the decoded image onto a recording medium so that either an image encoded from the original image or an image decoded from the encoded image is recorded.
