Method for processing image, image processing apparatus, and imaging apparatus

An image processing apparatus comprising:

• an acquisition unit configured to acquire image data;
• a correction unit configured to correct chroma information of the acquired image data based on at least one of hue information and luminance information of the image data;
• a determination unit configured to determine whether a scene of an image of the image data is a vivid color scene using the corrected chroma information,
• wherein the scene of the image is determined to be a vivid color scene in a case where the corrected chroma information corresponds to a first chroma information and the scene of the image is determined not to be a vivid color scene in a case where the corrected chroma information is a second chroma information corresponding to lower chroma than the first chroma information, and
• wherein the correction unit corrects the image data in the case that the scene of the image is determined to be a vivid color scene.

An image capturing apparatus comprising:

• an imaging unit configured to capture an image of a subject and output image data;
• a correction unit configured to correct color saturation information of the image data based on at least one of hue information and luminance information of the image data;
• a determination unit configured to determine whether an image of the image data is a vivid color scene based on the color saturation information corrected the correction unit;
• an output unit configured to output a result of scene determination by the determination unit;
• a display unit configured to display an image of the captured image data and the output result,
• wherein the scene of the image is determined to be vivid color scene in a case where the corrected chroma information corresponds to a first chroma information and the scene of the image is determined not to be a vivid color scene in a case where the corrected chroma information is a second chroma information corresponding to a lower chroma than the first chroma information, and
• wherein the correction unit corrects the image data in the case that the scene of the image is determined to be a vivid color scene.

An image processing method comprising:

• acquiring image data;
• correcting chroma information acquired from the image data based on at least one of hue information and luminance information of the image data;
• determining whether a scene of an image of the image data is a vivid color scene using the corrected chroma information;
• and
• outputting the result(s) of the scene determination,
• wherein the image data is segmented into a plurality of blocks, each block comprising a plurality of pixels, and weights corresponding to hue information of each of the blocks are applied in correcting chroma information for each of the blocks.

A method of image processing comprising:

• acquiring image data;
• obtaining, by a circuit, chroma and luminance information of the image data;
• determining, by a circuit, whether a scene of an image of the image data is a vivid color scene using the obtained chroma information such that the scene of the image is more likely to be determined a vivid color scene in a case where the luminance information corresponds to a first luminance information than in a case where the luminance information corresponds to a second luminance information corresponding to lower luminance than the first luminance information;
• and
• outputting a result of the scene determination.
