The present invention relates to a technology of implementing color correction using RGB data without a color spatial conversion for color correction. For this, the present invention comprises: a step of extracting a start color value on color coordinates for input data of RGB; a step of extracting vertical color value of the start color value based on each of the color control values of RGBYCM; a step of converting input values of R, G and B according to the vertical color value using a transformation formula according to corresponding input color value among multiple transformation formulas; a step of extracting a final value of a degree of saturation in the vertical color value according to a control value of degree of saturation of RGBYCM; and a step of computing R, G and B values according to the converted start color values using transformation formula of RGB color saturation degree value. By this, color loss in the color correction process can be prevented when using the present invention. |
