Examining Pixim's New WDR Seawolf Chip

Pixim released a new chipset called Seawolf for IP and analog cameras. The company claims that the Seawolf chip provides a 10x improvement in low light performance, improved WDR support, and accurate color representation within a single digital chip.  A technical specification and board camera brief is available.

Speaking with Pixim, they clarified the 10x low light performance is from comparing Seawolf to their current Orca/Orca-E line of sensors. The specifications list the Orca having a minimum illumination of 0.8 lux, while the Seawolf is at 0.1 lux. We have not tested this chip, so we cannot verify the validity of this claim.

We asked about the Seawolf chip's WDR performance. Pixim explained that bright areas in a scene will perform similar to Orca, but for dark areas, the sensor's SNR is increased, revealing more details. Like the first claim, the validity of this point is not confirmed- This should be followed closely because of the industry's criticism toward Pixim and its history of poor low light WDR performance.

Pixim also elaborated on these additional points:

Update: February 2011: We tested a camera using the Pixim Seawolf as part of our WDR comparative testing. While the low light performanced did show improvements, the WDR performance of both cameras using Pixim chips were inferior to MP WDR camera rivals. Review our WDR test results including Pixim.
