Abstract
An image processing device includes an image output unit, an image input unit, and a tone-correction-parameter generation unit. The image output unit outputs a tone-correction-parameter generation sheet to generate a parameter for correcting a tone of an input image. The tone-correction-parameter generation sheet includes a plurality of patches for at least two types of screens. At least one of the at least two types of screens includes more patches of an identical color and tone than at least another of the at least two types of screens. The image input unit inputs a representative value of each patch read from the tone-correction-parameter generation sheet outputted by the image output unit. The tone-correction-parameter generation unit generates the parameter in accordance with a plurality of representative values inputted by the image input unit.
