Color correction device and color correction method |
摘要 |
A color correction device for correcting colors in a color image, comprising: standard point registration means for registering coordinates of a standard point on a color space for at least one color to be used as a standard for color correction; object point registration means for registering coordinates of an object point on the color space which corresponds to a standard point and which is a desired color after color correction; and coordinate conversion means for determining a mapping function based on the standard point and the object point, and for generating a corrected color image by using the mapping function to convert pre-correction points on the color space which are equivalent to a color of each pixel in an inputted pre-correction image. By means of the construction described above, all of the colors in a color space can be converted based on at least one pair of standard point and object point. As a result, precise color correction can be easily achieved.
