Method for improving chromatic text resolution in images with reduced chromatic bandwidth

摘要

A method for improving chromatic text resolution includes transforming a color image signal into chrominance (C1, C2) image signal components and a luminance (L) image signal component. A mask is created for a selected image object from the luminance image signal components. The C1 and C2 image signal components are modified by the mask into new image signal components, C1NEW, C2NEW, respectively. The new image signal components are transformed, with L, into a new color image signal that does not have chromatic blur.
