Brillnics Presents its First Products

Japan and Taiwan-based startup Brillnics unveils its first products for security and surveillance applications: two new 1/2.7” 1080p color BSI CMOS sensors: BRV0200 (60fps) and BRV0201 (120fps) utilizing Brillnics patented H³DRTM technology.

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, CEO of Brillnics and former TSMC CIS group manager. “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 HDR approaches, 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 QE and low readout noise floor. Also, the very high full well capacity has been realized in the close collaboration with the strategic foundry partner.

Product Highlights:
  • Process: BSI
  • Pixel Size: 3.0 um
  • Optical Format: 1/2.7”
  • Angular Response: 85% @ ±20°
  • Max Frame Rate: 120fps, 12bit (BRV0201)
  • Hybrid Modes HDR: MEHDR/SEHDR
  • SE HDR: Dual conversion gain readout in single exposure time
  • SE HDR >85dB and ME HDR 120dB
  • SNRmax: 44dB
  • Power consumption: typ. 178mW at 60fps, 12bit


  1. it seems quite classic solution. What is the noise electron number please?

    1. From the SNRmax and the SE HDR figures it seems the well capacity should be 25ke and the high gain readout noise should be ~1.4e.
