CMOS image sensor has high dynamic range
Colour high dynamic range CMOS image sensor functions much like the human eye under quickly changing light conditions.
OmniVision Technologies has introduced its first colour high dynamic range (HDR) CMOS image sensor for mass market applications Dynamic range refers to the capacity of an imaging system to capture widely differing light levels in a single image and to rapidly adjust to changes in light levels

OmniVision Technologies has introduced its first colour High Dynamic Range (HDR) CameraChip sensor for security market applications.
Image sensor aims for high-volume handsets
OmniVision Technologies has released its first CameraChip based on the Standard Mobile Imaging Architecture introduced by Nokia and STMicroelectronics in January 2004.
The new OV10620 is an affordable, single-chip, high-performance camera solution and marks OmniVision's entry into colour HDR commercialisation.
OmniVision's proprietary colour HDR technology enables the high-speed OV10620 to function much like the human eye under quickly changing light conditions.
It rapidly switches to HDR mode to handle extreme variations of bright and dark conditions within the same scene and automatically switches back to non-HDR mode when conditions return to normal.

Smart optical sensor is child's play
This week OmniVision Technologies has been offering the toy industry a glimpse into the future of smart toys at the American International Toy Fair in New York.
The new single-chip sensor boasts a spectral light sensitivity of up to 1000nm, which is near infrared sensitivity.
In addition, its 6 x 6um pixel sise enables it to simultaneously capture and process image data ranging from bright sunlight to dark shadowed regions.
"We believe that the introduction of this new colour HDR chip will provide important functionality for many applications", said Hasan Gadjali, Vice President for Advanced Products at OmniVision.
"HDR functionality is especially important in the automotive and security markets, where colour recognition can be a critical element in producing useful images".
Typical automotive applications for the OV10620 would include backup and rear-view cameras, lane departure warning and guidance systems, blind spot detection systems and forward looking sensing applications, such as automatic headlight dimming.
In security applications, the sensor will be used in high-performance closed circuit television (CCTV) and Internet protocol (IP) camera systems.
The OV10620 digital sensor comes in a one-third-inch wide-VGA (768 x 492) and a quarter-inch VGA (640 x 480) image array operating at 30 frames per second at full resolution and 60 frames per second at QVGA (320 x 240) resolution.
It offers the flexibility of YUV or RGB raw output and is capable of performing at a dynamic range of up to 110dB in either colour or black and white.
The new OV10620 has an operating temperature range of -40 to +105C and comes in a standard QFP, CLCC and CSP packages.
Customer samples and evaluation boards are now available and the company expects to begin volume production in the third quarter of 2007.
