Abstract:
An image processing unit is configured to include a monotone image generator which generates a monotone image from a color image and a color reducer which reduces a color of an image by reducing chroma of the image in accordance with brightness of the image. The color reducer adjusts a tone of the monotone image generated by the monotone image generator by reducing a color of a high brightness portion of the image at a higher level than a low brightness portion of the image.
