Abstract

The invention is a flicker filter for use with video signals. The flicker filter of the invention has at least two user-adjustable inputs adapted to balance image quality versus flicker in the second video image. A first user-adjustable input is adapted to govern an amount of flicker suppression. A second user-adjustable input is adapted to govern an amount of blur, or sharpness. The two inputs are independently adjustable such that a user may dynamically adjust the two-dimensional system characteristics. This ability allows the circuit to be tune to adjust pixel intensities where an amount of pixel intensity adjustment increases with decreasing boundary angle, inter alia.
