電子カラー画像の色を補正する画像処理方法

Japanese Patent JP4142360

B2

The color of a color image having at least two sets of image pixels having color and luminance values is corrected by generating, for each color value, a low spatial frequency monochrome image including a set of smoothed image pixels. A color correction function is applied to selected sub-sets of the image pixels to generate corresponding sub-sets of corrected, smoothed image pixels. The correction includes a contribution from smoothed image pixels in one or more of the other sets of smoothed image pixels. The sub-sets of corrected smoothed image pixels is completed by interpolation or extrapolation. Each set of corrected smoothed image pixels is used to generate a corrected color image by generating one or more high spatial frequency luminance images that are combined with each of the corrected low spatial frequency monochrome images to form a full color image.
