Abstract: When this image processing device forms an image on a sheet, an image data storage unit stores image data received by an image data reception unit. An image formation count unit counts the number of times the image of the stored image data is formed by an image output unit.

The converter performs a frequency conversion operation on a color image signal which includes a brightness signal and color signals and divides values of each of the brightness signal and the color signals into high frequency coefficients and a low frequency coefficient. The calculator calculates the high frequency coefficients of the brightness signal and the color signals, generates a set of different high frequency coefficients, and produces a new brightness signal by adding the low frequency coefficient of the brightness signal to the set of different high frequency coefficients. The reverse converter performs a reverse frequency conversion operation on the new brightness signal.
