In three-dimensional dependence color gamut mapping, hello hello

摘要

Topic Hello the artefact is decreased with the revision section of color gamut mapping algorithm.Solutions As for the color image as for the picture inside f and color gamut as for the color gamut of g and the target C, as for color gamut restriction it is displayed by c. As for this invention, color distance section L of 1st, color gamut mapping algorithm₂ is revised and (110), distance measurement of picture slope of 2nd, color gamut mapping algorithm is revised (115). Function u=project _c (f) it calculates 1st revision step, 2nd revision step the reduction for f (scaled down) calculates function. Next, the function g which makes the functional which includes the color distance section and the picture slope section smallest (x, y), g _{o=project c} (f) initializes, g (x, y) the repetition which uses the slope drop operation with calculating (130 - 145) is furthermore required.
