Otopiksli bir renkli televizyon icin non-lineer müsteri kontrast kontrolü.

摘要

A video signal processing system having an autopix feedback loop (41) for limiting the range over which the contrast can be controlled includes a non-linear contrast control feature (81). A non-linear contrast control voltage (V4) is generated as a function of customer control settings (PS) to extend the range over which the customer can control the contrast.
