PPROBLEM TO BE SOLVED: To provide an image processor which performs correction process using a color chart made different in the number of patches, density, or patch size according to a pattern of a screen. PSOLUTION: The image processor is characterized in that it includes an output means 5 outputting a color chart which is a table where a plurality of patches are arrayed, a read means 6 reading density of each patch out of the color chart, a calculating means 7 calculating an adjustment value from the density, and a correcting means 8 correcting the grayscale of the output means 5 based on the calculated adjustment value. The image processor includes a storage means 3 storing colors of a standard color chart, the numbers of the patches corresponding to the respective colors, density, and the size of the patches, and an operation means 2 for inputting change of the stored numbers of the patches, density, or size of the patches. The output means 5 receives input information, and change at least one of the stored standard numbers of the patches, density, and size of the patches to generate the color chart.
