First Claim
Patent Images
1. A method for improving a sharpness of at least one color of a digital image, from an image-capturing device, comprising:
- selecting from among the colors at least one color as a sharp color; and
reflecting the sharpness of the sharp color onto at least one other improved color, so that the improved colour represents increased sharpness,wherein repercussion of the sharpness of the sharp color on the at least one other improved color is based on a calculation of a type CA=CN+F(CO−
CN), where CA represents the improved color, CO represents the improved color prior to processing, CN represents the sharp color, and F represents a filter, the filter being a low-pass filter.
