Abstract
Abstract An image processing method matches the gradations of a first output unit and a second output unit which have different gradation-reproduction ranges. The image processing method sets first-output-unit information on the first output unit, sets output-medium information for use in the second output unit, and finds an output-gradation reproduction curve from the first-output-unit information and the output-medium information.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
An image processing method for performing gradation matching between images formed by a first output unit and a second output unit which have different gradation-reproduction ranges, said image processing method comprising the steps of: controlling the first output unit to output a gradation image in accordance with image data representing gradation; controlling the second output unit to output a plurality of gradation images corresponding to the results of different gradation processes on the image data representing gradation; inputting information for, from among the plurality of gradation images output from the second output unit, selecting a gradation image corresponding to the gradation image output from the first output unit; and setting gradation conversion conditions for the second output unit by using the selected gradation image as a target.
Claim 2
Dependent Claim
127 words
