Color-sample image generator, color-sample generator, color-sample generation method, and color-sample

A color-sample generator comprising:

• an all-pixel acquisition unit configured to obtain all pixels of a first area of a first image from which a color sample is to be extracted;
• a lightness measuring unit configured to measure a level of lightness of each pixel of the first area obtained by the all-pixel acquisition unit;
• and
• a color-sample image generator configured to rearrange each of the pixels whose lightness has been measured by the lightness measuring unit, based on the level of lightness, in a second area of a second image that is different from the first area, to generate the color sample.

A color-sample generation method comprising:

• using a processor,
• obtaining all pixels of a first area of a first image from which a color sample is to be extracted;
• measuring a level of lightness of each of the obtained pixels of the first area;
• rearranging each of the pixels whose lightness has been measured based on the level of lightness, in a second area of a second image that is different from the first area;
• and
• storing in a memory the second image having the pixels that are rearranged based on the level of lightness as a color sample.
