Patent ID: 7738141

Claim:
An image processing device comprising: a printing unit that prints an image based on print data, the printing unit having characteristics; an input-color-data storing portion that stores input color data indicative of colors of inputted image data, the input color data having color component values of a first color group, each of the color component values of the first color group indicating a color density; a print-data generating portion that converts the color component values of the first color group stored in the input-color-data storing portion into color component values of a second color group, thereby generating pre-correction print data representing a single pixel and having a predetermined bit width, each of the color component values of the second color group indicating a color density; and a correcting portion that converts the pre-correction print data representing the single pixel into post-correction print data representing the single pixel that is adapted to the characteristics of the printing unit, wherein the correcting portion comprises a bit-width correcting portion that generates the post-correction print data representing the single pixel and having a bit width greater than the predetermined bit width when the color component value of the pre-correction print data indicates a color density that is lower than or equal to a predetermined color density value.
