Abstract
A tentative defective nozzle is set for each of K comparison regions associated with K provisional compensation coefficients different from each other. K pieces of sample image data are extracted from a captured image of a compensation coefficient calculation chart obtained by performing an ink amount compensation process on predetermined image data while applying the K provisional compensation coefficients to the K comparison regions. A function representing a correspondence relationship between a coefficient value and a luminance difference between a measured luminance value and a target luminance value is generated based on the K pieces of sample image data. A compensation coefficient to be actually applied to the ink amount compensation process is calculated using the function.
