Image processing apparatus, method and storage medium that obtain a first lookup table (LUT) for a predetermined format conversion and apply an effect of a desired color conversion

An image processing apparatus comprising:

• at least one processor and/or a circuit;
• and
• at least one memory storing computer program, which causes the at least one processor and/or circuit to function as the following units:
• an obtaining unit configured to obtain a first lookup table (LUT) for a predetermined format conversion and applying an effect of a desired color conversion;
• a specifying unit configured to specify an effect of the predetermined format conversion, of an effect of the first LUT;
• a setting unit configured to set an influence of a LUT to be applied to a first image for processing;
• and
• a processing unit configured to generate a second image from the first image on a basis of the influence, the first LUT, and the predetermined format conversion, wherein the processing unit combines a third image obtained by applying the first LUT to the first image and a fourth image obtained by applying an effect of the predetermined format conversion to the first image on a basis of the influence to generate the second image.
