Image processing system, image processing device, and computer program

An image processing device for converting a color space represented by color components of image data, the image processing device comprising a color space converter configured to correct the color components of the image data by converting the color space

• such that influence of chromatic adaptation caused by ambient light is maintained with respect to for particular color components belonging to a portion of a color gamut of the image data, wherein a perceived color gamut is widened relative to the color gamut in the portion due to the influence when a user perceives color in the color gamut under the ambient light, and
• such that the influence is canceled for particular color components belonging to another portion of the color gamut, wherein the perceived color gamut is narrowed relative to the color gamut in the another portion due to the influence when the user perceives color in the color gamut under the ambient light.

An image processing method for converting a color space represented by color components of image data, the image processing method comprising a color space conversion step of correcting the color components of the image data by converting the color space

• such that influence of chromatic adaptation caused by ambient light is maintained for particular color components belonging to a portion of a color gamut of the image data, wherein a perceived color gamut is widened relative to the color gamut in the portion due to the influence when a user perceives color in the color gamut under the ambient light, and
• such that the influence is canceled for particular color components belonging to another portion of the color gamut, wherein the perceived color gamut is narrowed relative to the color gamut in the another portion due to by the influence when the user perceives color in the color gamut under the ambient light, the influence is canceled.
