CTOnews.com, March 13 (Xinhua)-- Howell Group has released a new high-performance, low-power 2K 4-megapixel image sensor for consumer security and surveillance cameras.

Howie said the 4-megapixel image sensor provides 2K resolution digital images and 30 frames per second video for IP cameras and high-definition analog security cameras, including smart homes, doorbells and baby surveillance devices.

▲ image source: Howie CTOnews.com learned from Howie officials that the OS04D CMOS image sensor uses a high-performance backlit (BSI) pixel design, which reduces power consumption by 40%, increases signal-to-noise ratio (SNR1) by more than 30%, and increases sensitivity by 40% compared with the previous generation.

According to reports, the OS04D image sensor is based on Howell's patented PureCel Plus technology and uses 2.0 micron BSI pixels. Selective conversion gain (SCG) enables the sensor to select low and high conversion gains according to lighting conditions. On-chip automatic exposure control (AEC) and automatic gain control (AGC) can further shorten the startup time of the system chip (SoC). Low power consumption is beneficial to battery-powered devices, especially doorbell security cameras.

In addition, the OS04D uses the mainstream 1amp 3-inch optical size, which is pin compatible with Howie's OS04L image sensor and other new products to be launched in the future.
