Abstract :
An integrated circuit realizing the nonlinear transfer function Y= X/sup gamma/(gamma = 0.2 · · · 1) is presented. This circuit, especially intended for processing video signals with frequencies up to 6 MHz, features easy adjustment of gamma. A video clamp circuit has been integrated on the chip as well to provide a great flexibility to the user. A great field of application can be the processing of video signals in low-cost consumer cameras.
