Sunnyvale, Calif. OmniVision Technologies, Inc. has launched the OV2650, its third generation 2-megapixel CameraChip sensor. The OV2650 is said to bring digital still camera (DSC) performance to camera phones in a 1/5-inch optical format, enabling an easy upgrade of existing 1.3-megapixel and VGA camera phone designs. The OV2650 can also be used in digital still camera, PC multimedia and toy sectors.
Leveraging OmniVision's proprietary 1.75-micron OmniPixel3 technology with advanced image signal processing (ISP), the OV2650 is said to deliver low-light performance of 520 mV/lux-sec, excellent color reproduction and ultra-low noise. The image sensor also offers other advanced features including anti-shake technology for easier picture taking, high dynamic range (HDR) for advanced video functionality (85 dB), a high-speed mobile industry processor interface (MIPI) for easier picture sharing, and a high-end ISP to deliver DSC-like performance.
One of the most important new features of the OV2650 is the sensor's integrated anti-shake technology, said OmniVision. Anti-shake comes into play in low-light situations when cameras need a longer exposure time and therefore a steadier hand. When camera phones using the sensor detect the slightest camera movement, image stabilization will activate to prevent image blur. Also, the HDR capability enables the sensor to handle extreme variations of bright and dark conditions within the same scene and, similar to the human eye, adjust to changes rapidly. This is especially useful when a camera phone is operating in video mode, said OmniVision.
The OV2650 includes an integrated parallel and one-lane high-speed MIPI interface, which allows the rapid transfer of large blocks of data, an element critical to making effective use of increased camera resolutions, said OmniVision. The image sensor also incorporates onboard JPEG compression to allow existing baseband processors without MIPI to support a camera upgrade to 2 megapixels.
Availability: Samples are available now with volume production in first quarter 2008.
