Abstract
An image processing apparatus includes a first setting unit configured to set a target range of a luminance level, and a generation unit configured to generate a processed image by performing image processing on a first region of an image in such a manner that the first region is distinguished from a second region and a third region, the first region having a luminance level included in the target range and having a color not included in a target color gamut, the second region having a luminance level not included in the target range and having a color not included in the target color gamut, and the third region having a luminance level not included in the target range and having a color included in the target color gamut.
Claims18
An image processing apparatus for visualizing an out-of-gamut region of an image, the apparatus comprising:
- at least one processor and/or at least one circuit to perform operations of:
- setting a target range of a luminance level;
- and
- generating a processed image by converting a color of a first region of the image into a predetermined color, the first region having a luminance level included in the target range and having a color not included in a target color gamut, and converting a second region of the image into a monochrome image without the predetermined color, the second region of the image including a region having a luminance level not included in the target range and having a color not included in the target color gamut, and a region having a color included in the target color gamut,
- wherein the target range is a range of a luminance level being equal to or higher than a luminance threshold that is set based on a user instruction such that a region of the image having a luminance level being lower than the luminance threshold is not converted into the predetermined color.
A method of visualizing an out-of-gamut region of an image, the method comprising:
- performing a first setting process to set a target range of a luminance level;
- and
- generating a processed image by converting a first region of the image into a predetermined color, the first region having a luminance level included in the target range and having a color not included in a target color gamut, and converting a second region of the image into a monochrome image without the predetermined color, the second region of the image including a region having a luminance level not included in the target range and having a color not included in the target color gamut, and a region having a color included in the target color gamut,
- wherein the target range is a range of a luminance level being equal to or higher than a luminance threshold that is set based on a user instruction such that a region of the image having a luminance level being lower than the luminance threshold is not converted into the predetermined color.
A non-transitory computer-readable storage medium storing a program that is readable and executable by a processor, the program causing the processor to execute following functions of an image processing apparatus, the functions comprising:
- performing a first setting process to set a target range of a luminance level;
- and
- generating a processed image by converting a color of a first region of an image into a predetermined color, the first region having a luminance level included in the target range and having a color not included in a target color gamut, and converting a second region of the image into a monochrome image without the predetermined color, the second region of the image including a region having a luminance level not included in the target range and having a color not included in the target color gamut, and a region having a color included in the target color gamut,
- wherein the target range is a range of a luminance level being equal to or higher than a luminance threshold that is set based on a user instruction such that a region of the image having a luminance level being lower than the luminance threshold is not converted into the predetermined color.
