OmniVision
Technologies' two new system-on-a-chip (SOC) CMOS image sensors, the OV2643 and OV2659, are designed to
address the increased demand for 2-megapixel resolution cameras in the mid- to
low-end feature phone segment.
The two new SOC sensors with advanced image signal
processing offer quality and functionality comparable to many high-performance
digital still cameras, including 720p native HD video at 30 frames per
second, excellent sensitivity and high-quality image capture. Additionally,
they are designed to meet the cost, size and performance requirements of the
highly segmented camera phone market.
Designed for cost-sensitive applications, the OV2659 is
built on OmniVision's 1.75-micron OmniPixel3-HSTM architecture, which achieves
low-light sensitivity of 950 mV/lux-sec. The OV2659's 1/5-inch optical format
and ultra-low profile (4 mm) fits the industry-standard 6.5 x 6.5 mm camera
module size for handset applications.

The OV2643 targets more performance-centric applications,
implementing OmniVision's advanced
2.2-micron OmniPixel3-HS architecture, which achieves a sensitivity of 1250
mV/lux-sec. The OV2643's 1/4-inch
optical format also fits the critical 6.5 x 6.5 mm camera module size.
Both sensors offer automatic image control functions, which
include automatic exposure control, automatic white balance and automatic
black-level calibration. They also feature all standard image quality controls
such as color saturation, hue, gamma, sharpness (edge enhancement), lens
correction, defective pixel canceling and noise canceling. The OV2643 also
features black sun cancelation.
The OV2643 and OV2659 are sampling now and are expected to
enter mass production in Q4 2010.
