ABSTRACT:
An image processing device includes a memory that is adapted to store an input image; an inverted image generator that is adapted to generate an inverted image, the inverted image corresponding to a predetermined part of the input image; a target image generator that is adapted to generate a target image, the target image including the inverted image and the input image; a quantization unit that is adapted to quantize the target image, in accordance with the error diffusion method; an image extractor that is adapted to extract an output image from the quantized target image, the output image corresponding to the input image; an output unit that is adapted to output the output image extracted by the image extractor.
