摘要

PROBLEM TO BE SOLVED: To provide an image processing method for correcting the irregularity of a recording head without altering the driving conditions or the like of the recording head such as an ink jet recording head, a thermal head or the like. SOLUTION: In an ink jet recording apparatus having an ink jet head having a plurality of nozzles formed thereto and forming an image on the basis of multi-value image data, aγcorrection parameter is selected corresponding to the jet characteristics to the input gradation level of the recording head or corresponding to the brightness characteristics of a printing image to the input gradation level to form an image on the basis of the selectedγcorrection parameter. For example, even if there is irregularity in the brightness characteristics of the recording head as shown by Fig 9, theγcorrection parameter optimum to the recording head is selected to form the image to obtain a constant image quality even if the recording head is replaced.
