Tamron Develops 140dB DR Image Sensor

Nikkei: Tamron announces successful development of an innovative image sensor technology, with support of Japan Science and Technology Agency (JST) of National Research and Development Agency, that enhances imaging capability far exceeding that of human vision, featuring ultra-high light sensitivity and WDR.

The new technology is said to enhance both sensitivity and DR, which has been considered difficult in the past. The ultra-high sensitivity enables capturing clear color images even under an extreme low brightness of 0.003 lux, which is darker than starlight. The WDR performance is exceeding 140dB.


Three key technologies - Optics, Image Sensor, and Image Processing - have been identified essential, and their effective integration has been studied for the new imaging technology:


This development is supported by Japan Science and Technology Agency (JST), Adaptable and Seamless Technology transfer Program through Target-driven R&D (A-STEP).

  1. I'm highly interested in the optics for our 160dB camera.

  2. Arnaud, which sensor are you using for getting 160dB?

    1. It's easy to have 160dB with a 100dB hole inside the SNR :)-

    2. It is >140dB with no SNR hole. It has smooth enough response to avoid deep SNR dips. It is combined with software reconstruction.

  3. How does it cost?? That's the key problem...

  4. Is the 140-dB DR achieved with multiple sequential exposures?

  5. Total theory, not a real sensor.
