From a cost and productivity perspective, the recording and color-measurement of a test pattern to determine whether it is necessary to execute calibration places a heavy burden on a user. The present invention determines the need for processing to generate a color correction parameter without recording a test pattern. More specifically, the present invention determines whether it is necessary to execute color correction parameter generation processing based on an increase in a dot count since color correction parameter generation processing was previously executed, or a change in a ejection rate.
