Abstract
Vertical dithering is performed for vertical droop compensation in image processing using Linear Feedback Shift Registers (LFSRs). Line memories are not used. A compensation circuit includes a signature reload input signal coupled to the input of five LFSRs. Each LFSR includes a signature store. The output of each LFSR provides a sequence output signal that is gated with a corresponding enable signal in a first logic circuit. The output of all of the first logic circuits are combined in a second logic circuit to provide a control signal output.
