Abstract
An image processing apparatus includes a first pixel replacing unit for replacing the positions of pixels in image data in accordance with a replacement rule so as to increase redundancy of the image data, an encoder for encoding the image data supplied from the first pixel replacing unit, an optical disk device for storing the image data encoded by the encoder, a decoder for decoding the image data supplied from the optical disk device, a second pixel replacing unit for replacing the positions of pixels in the image data supplied from the decoder to restore the image data before replacement by the first pixel replacing unit, an output unit for outputting the image data, a third pixel replacing unit for replacing the positions of pixels in the image data to be outputted on the output unit, and a pixel density varying unit for varying the pixel density of the image data supplied from the third pixel replacing unit.
