Brillnics Unveils 2-Megapixel BSI Starlight Sensors with Industry’s Leading Brillnics H³DRTM Technology for Video Surveillance Applications
Tokyo, Japan and Hsinchu, Taiwan, January 1, 2017 – Brillnics Inc., a leading designer and developer of CMOS imaging sensor products today announced two new 1/2.7” 1080p digital-output color CMOS image sensors: BRV0200 (60fps) and BRV0201 (120fps). Built on high performance Back Side Illumination (BSI) process and Brillnics patented Brillnics H³DRTM technology, these two devices are designed for security/surveillance and high-end video applications.
“We see customers expecting high imaging quality under extremely low light for various video applications. Collaborating with strategic foundry partner, Brillnics uses BSI technology featuring high sensitivity, high angular response, and low noise.”, said Dr. Shou-Gwo Wuu, Chief Executive Officer of Brillnics Inc. “We are particularly excited about the introduction of single exposure HDR (SE HDR), which can significantly mitigate motion artifacts caused by moving objects. SE HDR allows the highest video fidelity in fast-moving scenes, such as in automotive applications.”
In comparison with most common approaches to obtaining high dynamic range (HDR), including a logarithmic response pixel, a linear-logarithmic response pixel, a dual photodiode pixel, or a multiple exposure HDR (ME HDR) scheme, Brillnics adopts the multiple exposure HDR scheme and/or single exposure HDR scheme. The SE HDR mode obtains two data from a same pixel. One is a lower response and the other a higher response, of which integration times are identical with no timing shift, unlike the ME HDR. Linearization using the two data is then performed on-chip, yielding 16bit digital signal or 12bit compressed digital signal.
The high dynamic range of the BRV0200/0201 in SE HDR mode is made possible by its very high low-light sensitivity and very high full well capacity. The very high low-light sensitivity comes from its high quantum efficiency (the ratio of generated signal electrons to incident photons per pixel) and low readout noise floor. Also, the very high full well capacity has been realized by our excellent pixel design and close collaboration with the strategic foundry partner.
