An Analog Gamma Correction Scheme for High Dynamic Range CMOS Logarithmic Image Sensors

An Analog Gamma Correction Scheme for High Dynamic Range CMOS Logarithmic Image Sensors

In this paper, a novel analog gamma correction scheme with a logarithmic image sensor dedicated to minimize the quantization noise of the high dynamic applications is presented. The proposed implementation exploits a non-linear voltage-controlled-oscillator (VCO) based analog-to-digital converter (A...
