Tamron Develops Image Sensor With 140db Dynamic Range



Tamron Develops Image Sensor With 140dB Dynamic RangeTamron Co Ltd developed an image sensor technology to take clear color images in an environment with an illuminance of 0.003lx.
Its dynamic range (sensitivity) is 140dB. It enables to take a picture in the dark even when an image sensor is irradiated with light from headlamps in an environment darker than starlight, the company said.




The new technology was realized by using Tamron's own low-noise, wide-dynamic-range CMOS sensor and its optical technologies. The company combined (1) a low-reflection technology to reduce the noise for an optical system and (2) a technology to form an image from collected light by making the most of the pixels. Also, it applied an image processing technology to reduce noise while increasing dynamic range without lowering the resolution of moving objects.

Tamron developed the technology with help from Adaptable and Seamless Technology Transfer Program Through Target-driven R&D (A-STEP) of Japan Science and Technology Agency (JST).
