DETERMINING NEW COLOR VALUES OF AN IMAGE BASED ON AN ACITIVITY MAP |
| 摘要 |
A method comprises computing an activity map for an input image. The activity map indicates an amount of variable spatial activity in the input image. The method further comprises producing an output image based on the activity map, and controlling a printhead to cause the output image to be printed. The output image contains a plurality of color pixels and each such color pixel is represented by at least one of cyan (C), magenta (M), yellow (Y), and black (K) in a color space. |
