Abstract
A filter for decreasing sensor artifacts in an image frame as, for instance, sensor induced streaking in the image frame, has a frame buffer for temporary storing the picture elements of the image frame. A picture element mask is utilized to group related picture elements and statistics are collected with respect to these grouped picture elements. Correction parameters are determined utilizing these statistics and these are then utilized to correct the individual picture elements to remove the sensory induced artifacts. The statistics can be collected with respect to picture element gain and picture element offset with the correction parameters then determined utilizing the picture element gain and picture element offset.
