Image processing apparatus, image processing method, and non-transitory computer-readable storage medium storing program that generate image data having undergone color gamut conversion from input data

An image processing method comprising:

• generating image data having undergone color gamut conversion from input image data using conversion data for converting from a color gamut of the input image data into a color gamut of an output;
• and
• correcting first conversion data to second conversion data based on a result of the color gamut conversion of using the first conversion data,
• wherein the generation unit further generates the image data having undergone the color gamut conversion using the second conversion data,
• first output data generated as a result of the color gamut conversion using the first conversion data from first image data including a first color and a second color includes a third color corresponding to the first color and a fourth color corresponding to the second color,
• second output data generated as a result of the color gamut conversion using the second conversion data from the first image data includes a fifth color corresponding to the first color and a sixth color corresponding to the second color, and
• a second color difference corresponding to a distance between the fifth color and the sixth color is greater than a first color difference corresponding to a distance between the third color and the fourth color.

A non-transitory computer-readable storage medium storing a program configured to cause a computer of an information processing apparatus to function as:

• a generation unit configured to generate image data having undergone color gamut conversion from input image data using conversion data for converting from a color gamut of the input image data into a color gamut of an output device;
• and
• a correction unit configured to correct first conversion data to second conversion data based on a result of the color gamut conversion of using the first conversion data by the generation unit,
• wherein the generation unit further generates the image data having undergone the color gamut conversion using the second conversion data,
• first output data generated as a result of the color gamut conversion using the first conversion data from first image data including a first color and a second color includes a third color corresponding to the first color and a fourth color corresponding to the second color,
• second output data generated as a result of the color gamut conversion using the second conversion data from the first image data includes a fifth color corresponding to the first color and a sixth color corresponding to the second color, and
• a second color difference corresponding to a distance between the fifth color and the sixth color is greater than a first color difference corresponding to a distance between the third color and the fourth color.

An image processing apparatus comprising:

• one or more circuits;
• or
• one or more processors and at least one memory, the at least one memory being coupled to the one or more processors and having stored thereon instructions executable by the one or more processors, wherein at least one of the one or more circuits or the execution of the instructions cause the image processing apparatus to function as:
• a generation unit configured to generate image data having undergone color gamut conversion from input image data using conversion data for converting from a color gamut of the input image data into a color gamut of an output device;
• and
• a correction unit configured to correct first conversion data to second conversion data based on a result of the color gamut conversion of using the first conversion data by the generation unit,
• wherein, in the image data corrected by the correction unit, a color difference in the image data having undergone the color gamut conversion by the conversion unit is expanded.
