Image processing device and method for correcting a color of a specific area in an image

An image processing method of correcting a color of a specific area in a target image into an appropriate color, the image processing method comprising:

• (a) acquiring the target image;
• (b) acquiring a representative brightness value representing the specific area in a first color space that has a brightness index value;
• (c) acquiring a plurality of representative color component values representing the specific area in a second color space that has no brightness index value and a plurality of color component values;
• and
• (d) correcting the color of the specific area on the basis of the representative brightness value and the representative color component values,
• wherein step (d) includes:
• (d1) correcting a brightness of the specific area by modifying the brightness index value in the first color space;
• (d2) correcting a brightness of the specific area by modifying the plurality of color component values in the second color space;
• and
• (d3) setting a first brightness correction degree in the correcting (d1) and a second brightness correction degree in the correcting (d2) on the basis of the representative brightness value.

A computer program embodied in a non-transitory computer-readable medium that executes on a computer an image-processing of correcting a color of a specific area in a target image into an appropriate color, the computer program executing, on the computer:

• (a) a function of acquiring the target image;
• (b) a function of acquiring a representative brightness value representing the specific area in a first color space that has a brightness index value;
• (c) a function of acquiring a plurality of representative color component values representing the specific area in a second color space that has no brightness index value and a plurality of color component values;
• and
• (d) a function of correcting the color of the specific area on the basis of the representative brightness value and the representative color component values,
• wherein the function (d) includes:
• (d1) a function of correcting a brightness of the specific area by modifying the brightness index value in the first color space;
• (d2) a function of correcting a brightness of the specific area by modifying the plurality of color component values in the second color space;
• and
• (d3) a function of setting a first brightness correction degree in the function (d1) and a second brightness correction degree in the function (d2) on the basis of the representative brightness value.
