An image processing device includes a resolution reducer, a detector, and a corrector. The resolution reducer generates, from an input image, low resolution images for pixel shift display being lower in resolution than the input image. The detector detects portions of the low resolution images corresponding to a specific pattern in which image quality degradation may occur. The corrector performs specific correction processing to reduce the image quality degradation on the portions of the low resolution images corresponding to the specific pattern.

Image processing apparatus, image processing method, and computer program product

A determining unit determines a color of a character. A color converting unit converts a chromatic color having a predetermined hue into the predetermined color and a chromatic color having a hue other than the predetermined hue and an achromatic color into a black color. A processing unit processes either one of a color character and a black character determined by the determining unit such that the color character having the chromatic color converted into the black color is relatively noticeable to the black character.

A device for converting a color image including multiple character images into a monochrome image is disclosed. The device includes a color conversion unit configured to reduce the image density of black character images included in the color image to a level lower than the image density of specific color character images included in the color image and having a specific color other than black during the conversion of the color image into the monochrome image.
