Image processing apparatus, image processing method, and storage medium

An image processing apparatus which generates data for forming an image, the image processing apparatus comprising:

• a first obtaining unit configured to obtain color signals representing colors of the image;
• a second obtaining unit configured to obtain a gloss signal representing gloss of the image;
• a third obtaining unit configured to obtain a predetermined number of dots of a recording material;
• a first determination unit configured to determine a number of dots of glossy recording material to be recorded in a first region of the image based on the gloss signal;
• a second determination unit configured to determine a number of dots of colored recording materials to be recorded in the first region based on the color signals such that a total amount of the number of dots of the glossy recording material to be recorded in the first region determined by the first determination unit and the numbers of dots of the colored recording materials to be recorded in the first region does not exceed the predetermined number of dots;
• a third determination unit configured to determine a number of dots of the colored recording materials to be recorded in a second region based on the color signals and the numbers of dots of the colored recording materials determined by the second determination unit.

An image processing method for generating data for forming an image, the image processing method comprising:

• obtaining color signals representing colors of the image;
• obtaining a gloss signal representing gloss of the image;
• obtaining a predetermined amount of a recording material;
• determining a recording amount of glossy recording material to be recorded in a first region of the image based on the gloss signal;
• determining recording amounts of colored recording materials to be recorded in the first region based on the color signals such that a total amount of the determined recording amount of the glossy recording material to be recorded in the first region and the recording amounts of the colored recording materials to be recorded in the first region does not exceed a predetermined amount;
• and
• determining recording amounts of the colored recording materials to be recorded in a second region of the image based on the color signals and the determined recording amounts of the colored recording materials.

A non-transitory storage medium storing instructions that, when executed by a computer, cause the computer to perform a method comprising:

• obtaining color signals representing colors of an image;
• obtaining a gloss signal representing gloss of the image;
• obtaining a predetermined amount of a recording material of the recording medium;
• determining a recording amount of glossy recording material to be recorded in a first region of the image;
• determining recording amounts of the colored recording materials to be recorded in the first region based on the color signals such that a total amount of the determined recording amount of the glossy recording material to be recorded in the first region and the recording amounts of the colored recording materials to be recorded in the first region does not exceed the predetermined amount;
• and
• determining recording amounts of the colored recording materials to be recorded in a second region of the image in which the glossy recording material is not recorded but the colored recording materials are recorded to form the image on the recording medium based on the color signals and the determined recording amounts of the colored recording materials.
