NIT announces a range of color sensors operating in logarithmic response mode. These new sensors are based upon NIT patented Native WDR pixel technology where the pixel photodiodes are used as single solar cells providing extraordinary intrinsic dynamic range without exposure time.
The new sensors deliver sharp and accurate colour images over a dynamic range exceeding 140 dB, without any setup or need for white balance. Specific algorithms for colour de-bayerisation have been developed in order to accomodate the specific logarithmic response of NIT sensors. The photoelectric signal response of NIT photodiodes is predictable and modeled with extreme accuracy which simplify the chromatic calibration process and further increase the colour stability over temperature changes.
A dedicated Native WDR pixel of 5.6 um size, implementing micro lenses and a colour bayer array has been designed and implemented first on a D1 - 768x576 pixels sensor. Youtube video links are here and here:
