2-Mpixel Image Sensors Eye High-Volume Phone Markets

The OV2643 and OV2659 system-on-a-chip (SoC) CMOS image sensors address the demand for 2-Mpixel resolution cameras in the mid- to low-end feature phone market. The SoCs offer functionality comparable to digital still cameras including 720p native HD video at 30 fps. For cost-sensitive apps, the OV2659 is built on a 1.75-mm OmniPixel3-HS architecture that achieves a low-light sensitivity of 950 mV/lux-sec. Its 1/5-inch optical format and 4-mm profile fits the industry-standard 6.5 mm x 6.5 mm camera module size for handset applications. The OV2643 targets performance-centric applications using the company’s 2.2-micron OmniPixel3-HS architecture to specify a sensitivity of 1,250 mV/lux-sec. Its 1/4-inch optical format also fits the standard camera module size. Both sensors offer automatic exposure control, automatic white balance, automatic black-level calibration, and all standard image quality controls such as color saturation, hue, gamma, sharpness, lens correction, defective pixel canceling, and noise canceling. The OV2643 also features black sun cancelation. Additionally, both provide support for UXGA, SVGA, and 720p with programmable controls for frame rate as well as video operations. Sampling now, expect mass production sometime in the fourth quarter. OMNIVISION TECHNOLOGIES INC., Sunnyvale, CA. (408) 542-3000.
