PROBLEM TO BE SOLVED: To provide an image processor, or the like applying various image processing to the received printing data, generating printable data with a printing engine and providing efficient printing when the printing data are gray data, and also inhibiting the increase of the storage regions and the increase in man-hours for preparing a look-up table when conducting color conversion for the gray data by using a one-dimensional look-up table. SOLUTION: The image processor 3 conducts the image processing including color conversion processing using a pre-generated three-dimensional look-up table 6 to the received printing data 5 and outputs the image-processed data to the printing engine 4. When the received printing data 5 are the gray data, the one-dimensional look-up table 8 is generated by using the three-dimensional look-up table 6 to conduct the color conversion processing by using the generated one-dimensional look-up table 8.
