Analog Implementation of Gamma-Correction for CMOS Cameras

R. Rovatti and E. Franchi and N. Manaresi and M. Tartagni and A. Bellini


In this paper an analog synthesizer of non-linear functions is applied to integrated color processing in CMOS cameras. For reproducing images on a display with desired contrast and color correction, a non-linear distortion of the signal associated with pixels of different colors is needed. The adoption of a design flow for the implementation of non-linear analog functions allows the integration of this processing on the same chip containing the sensor before the final A/D conversion.
