An electronic-calibration scheme for logarithmic CMOS pixels

Abstract:

Logarithmic cameras have the wide dynamic range required to image natural scenes and encode the important contrast information within the scene. However, the images from these cameras are severely degraded by a fixed pattern noise (FPN). Previous attempts to improve the quality of the images from these cameras by removing an additive FPN have led to disappointing results. Using an existing model for the response of logarithmic pixels, it is concluded that the residual FPN in these images is c...
