Abstract

A method to specify a color selection that allows users to construct verbal color descriptions of desired colors for color modification or correction using various components. These components include a user interface component for creating and combining color selection descriptions using menus or other suitable display techniques, a mapping or classifier component to map menu-items to representative color-samples, a component that translates representative color-samples to a mathematical selection transform and a component that maps a set of test colors through the mathematical selection transform to implement the color selector.

Claims

1. In a system having a user interface with representative color:

samples and a display screen, a method of editing color images comprising the steps of;

providing color selection descriptions using display screen menus,

mapping the color selection descriptions to the representative color-samples, and

translating the representative color-samples to selection transforms.

2. The method of claim 1 wherein the selection transforms comprise a given color encoding and including the step of transforming the representative color samples into the given color encoding of the selection transforms.

3. The method of claim 1 including the step of defining the representative color samples within the color selection descriptions.

4. The method of claim 1 including the step of defining the probability of the representative color samples being within the color selection descriptions.

5. The method of claim 1 wherein the step of providing color selection descriptions using display screen menus includes the step of constructing verbal color selection descriptions.

6. The method of claim 5 including the step of combining verbal color selection descriptions.

7. The method of claim 5 including the option of excluding a given color from the verbal selection descriptions.

8. The method of claim 5 including the step of providing a choice of color modifiers.

9. The method of claim 5 including the step of providing a choice of color names.

10. In a color imaging system, a method of color selection for color images including the steps of:

providing a user interface with screen for displaying information related to color images,

displaying a set of operations for providing color selection descriptions,

mapping the color selection descriptions to a set of representative color samples, and

translating the representative color samples to a mathematical selection transform.

11. The method of claim 10 wherein the step of displaying a set of operations for providing color selection descriptions includes the step of combining selected verbal color descriptions.

12. The method of claim 11 wherein the step of combining selected verbal color descriptions includes the step of selecting verbal color descriptions from the screen.

13. The method of claim 12 wherein the step of selecting verbal color descriptions from the screen includes the step of selecting verbal color descriptions from a set of menus on the screen.

14. The method of claim 12 wherein the step of selecting verbal color descriptions from the screen includes the step of providing a choice of color modifiers and a choice of color names.

15. The method of claim 10 wherein the mathematical selection transforms comprise a given color encoding and including the step of transforming the set of representative color samples into the given color encoding of the mathematical selection transforms.

16. In a color imaging system having a user interface with a screen for describing color corrections in verbal descriptions, a method of providing color correction for color images including the steps of:

providing a choice of verbal color modifiers on the screen for the color correction, and

providing a choice of verbal color names on the screen for the color correction.

17. The method of claim 16 including the step of selectively choosing verbal color modifiers and verbal color names for a given color correction.

18. The method of claim 17 including the step of selectively choosing verbal color modifiers and verbal color names from a set of menus on the screen.

19. In a system having a memory and a user interface with a display screen, a method of editing color images comprising the steps of:

providing color descriptions on the display screen of the user interface for selection,

selecting a set of color descriptions,

mapping the set of color descriptions to a set of color samples, the set of color samples being stored in memory, and

translating the representative color samples to a set of mathematical transforms.

20. The method of claim 19 wherein the mathematical transforms comprise a transform color encoding and including the step of converting the set of color samples into the transform color encoding.

21. The method of claim 20 wherein the set of color samples include arbitrary colors with color coordinates and including the step of converting the color coordinates of the arbitrary colors into the transform color encoding.

22. The method of claim 19 wherein the step of mapping the set of color descriptions to a set of color samples includes the step of defining the probability that each of the set of color samples is within the color descriptions.
