A color television receiver includes well-known circuitry for detection and display of a received broadcast signal. Image enhancement means produce an expanded element luminance signal. A differentiating network produces the derivative of the expanded-element signal and a differential amplifier couples the derivative signal in a "push-pull" fashion to a pair of electrostatic deflection plates which influence the horizontal scansion of the receiver. A method of image enhancement as well as derivative processing and signal delay structures are shown.
