Methods and apparatus for color grading with gamut match preview
First Claim
1. A method for color grading within a component color space associated with a display comprises:
- a) receiving a source image comprising a plurality of pixels, wherein each pixel is associated with a color comprising a plurality of color component values in the component color space, wherein the component color space comprises RGB, and wherein a pixel is associated with a color inside a gamut of the display but outside a gamut of a target media;
b) receiving a color grading signal from a user;
c) modifying, using a processor, the color associated with the pixel from the plurality of pixels in response to the color grading signal, to form a graded image comprising the pixel, wherein the pixel is associated with a graded color comprising a plurality of color component values;
d) displaying the graded image on the display to user;
e) automatically performing, using the processor, a gamut remapping of the graded color associated with the pixel, to form a gamut remapped image comprising the pixel, wherein the pixel is associated with a gamut remapped color comprising a plurality of color component values, wherein at least one color component value of the graded color is substantially similar to one color component value of the gamut remapped color; and
f) displaying the gamut remapped on the display to the user, wherein the gamut remapped image comprises a plurality of pixels, wherein each pixel from the plurality of pixels is associated with a color within a gamut of the target media.

Abstract
A method for color grading within a component color space associated with a display includes receiving a source image comprising a plurality of pixels, wherein each pixel is associated with a color comprising a plurality of color component values in the component color space, wherein the component color space comprises RGB, and wherein a pixel is associated with a color inside a gamut of the display but outside a gamut of a target media, receiving a color grading signal from a user, modifying the color associated with the pixel from the plurality of pixels in response to the color grading signal, to form a graded image comprising the pixel, wherein the pixel is associated with a graded color comprising a plurality of color component values, displaying the graded image on the display to the user, automatically performing a gamut remapping of the graded color associated with the pixel, to form a gamut remapped image comprising the pixel, wherein the pixel is associated with a gamut remapped color comprising a plurality of color component values, wherein at least one color component value of the graded color is substantially similar to one color component value of the gamut remapped color, and displaying the gamut remapped image on the display to the user, wherein the gamut remapped image comprises a plurality of pixels, wherein each pixel from the plurality of pixels is associated with a color within a gamut of the target media.

9. A method for matching colors in a source image associated with a first color space gamut to a target image associated with a second color space gamut, comprising:
-
receiving the source image; determining, using a processor, a respective at least one preferential color component for colors within the first color space gamut but not within the second color space gamut; adjusting, using the processor, the colors within the first color space gamut but not within the second color space gamut in the direction of the respective one preferential color component, wherein ordinality of colors within the first color space gamut but not within the second color space gamut are preserved; and determining, using the processor, a resulting image in response to the colors within the first color space gamut but not within the second color space gamut that were adjusted, and in response to the source image.

10. A method for forming a target image comprises:
-
a) receiving a source image; b) receiving color grading adjustment signals from a user to grade the source image within a target gamut; and c) adjusting, using a processor, colors in the source image that are not within the target gamut in a preferential direction, to form a target image. - View Dependent Claims (11, 12)
