High Dynamic Range Imaging: New Color Sensors

NIT announces a major advance in high dynamic range imaging by introducing a range of color sensors operating in logarithmic response mode.

These new color 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 color images over a dynamic range exceeding 140 dB, without any setup or need for white balance.

Specific algorithms for color de-bayerisation have been developed in order to accommodate the specific logarithmic response of NIT sensors.
The photoelectric signal response of NIT photodiodes is predictable and modeled with extreme accuracy which simplifies the chromatic calibration process and further increase the color stability over temperature changes.

A dedicated Native WDR pixel of 5.6 µm size, implementing micro lenses and a color bayer array, has been designed and implemented first on a D1 - 768 x 576 pixels sensor.
