COMPENSATION FOR ADJACENT PIXEL INTERDEPENDENCE
摘要:
A method and system for reducing pixel interdependence errors in an imager caused by adjacent pixel drive interdependence. The method compares a first brightness control level for a first pixel to a brightness control level for at least one adjacent pixel of the imager by pixel delay elements (102 and 104). Based on the results of the comparing step, estimator (106) estimate the pixel interdependence effect of the outer pixels on the adjacent piyel and the system modifies the first brightness control level for the first pixel to compensate for the pixel interdependence effect. The output of clipper (116), a modified brightness control level is determined for the first pixel that results in an actual brightness for the first pixel in the presence of pixel interdependence effect, which more closely approximates the actual brightness that would result from the un-modified first brightness control level in the absence of pixel interdependence effect.
