Abstract:
1. A circuitry-implemented method comprising image editing, the method comprising: (1) obtaining digital data representing coordinates of a color S in a first coordinate system, wherein the color S has tristimulus values T (A) the coordinate S wherein g 11 , g 22 , g 33 , g 12 , g 13 , g 23 are predefined constants, and g 11 , g 22 , g 33 are not equal to zero, or the coordinate S (B) a value cos S wherein β 1 , β 2 , β 3 are predefined numbers at least one of which is not equal to zero, or the value cos S (C) a value tan S wherein γ 1 , γ 2 , γ 3 are predefined numbers at least one of which is not equal to zero, and δ 1 , δ 2 , δ 3 are predefined numbers at least one of which is not equal to zero, or the value tan S (2) obtaining data indicating a desired change in the value S (3) obtaining color coordinates in the first color coordinate system of a modified color whose coordinate S
