Method and device for post-processing digital images

Abstract

The invention relates to a method of post-processing digital images, the method comprising a step of frequency transformation TF (21), suitable for delivering a set of transformed coefficients (Y) from a set of pixels (y), extraction SEP (22) of original low-frequency coefficients (Ybfo) and original high-frequency coefficients (Yhfo) comprised in the set of transformed coefficients, correction COR (23), suitable for delivering a set of corrected transformed coefficients (Yc) from the original low-frequency coefficients, and combination (24), suitable for delivering a set of combined transformed coefficients (Yadd) from the original high-frequency coefficients and from the set of corrected transformed coefficients, and a step of inverse frequency transformation ITF (25) of the set of combined transformed coefficients, suitable for delivering a processed set of pixels (yout) that are ready for display on a screen.
