OV2715 image sensor

OmniVision Technologies Inc. debuts the OV2715 1,080p HD CMOS image sensor optimized for the mainstream IP camera and high-definition closed-caption TV (HD CCTV) markets. It combines HD-quality video with low-light performance, making it particularly suitable for commercial security systems.

"The OV2715 is ideal for IP cameras requiring 1,080p HD resolution and also for the emerging HD CCTV market," said Roy Karunakaran, senior product marketing manager at OmniVision. "As one of the first suppliers to offer a native 1,080p HD sensor for the mainstream security market, OmniVision is ready for the industry's move to this new format and prepared to support this developing industry requirement."

Professional security installations with HD video capability are growing steadily due to the high quality image capture and detail they can record. Such HD surveillance systems are used predominantly in places where lighting conditions are often far from ideal. This makes image quality, low-light performance and dynamic range key drivers to the success of products for security and surveillance systems.

The 1/3-inch OV2715 is built on a 3?m OmniPixel3-HS pixel, delivering best-in-class low-light performance of 3,300mV/(lux-sec) and a peak dynamic range of 69dB. Such performance parameters allow the OV2715 to deliver high quality video surveillance even in the most challenging lighting conditions common to security applications such as lobbies, hallways, parking lots and garages.

The OV2715 is a no-compromise 1,080p HD sensor that offers the HD video format with a display resolution of 1,920 x 1,080 pixels and operates at 30fps. Competing 1,080p HD video solutions are based on reducing high-resolution sensors to a 1,080p display resolution through cropping or merging pixels by binning. However, cropping reduces the field of view, while binning degrades image quality, color reproduction and picture sharpness. Furthermore, higher resolution sensors require a smaller pixel size to achieve the same optical format as the OV2715; and shrinking pixels generally degrades low-light performance, significantly reducing their ability to meet the requirements of security and surveillance applications.

Offering a zero-degree chief ray angle, the OV2715 allows for the clearest possible picture and best-in-class image quality. The OV2715 is capable of operating within a temperature range of -30C to +70C, enabling its implementation in indoor and outdoor security and surveillance applications. OmniVision's OmniPixel3-HS pixel technology has already been proven in high quality surveillance applications and is also available in the 720p format in the OV9715.

The OV2715 is available for sampling with mass production scheduled to start in Q4.
