Cost-Effective VGA Sensor Delivers Best-In-Class Pixel
Performance to Wide Range of Consumer Applications
OmniVision's high performance OV7676 is a costeffective 1/7.5-inch system-on-a-chip (SOC) VGA
sensor that brings best-in-class pixel performance to a
wide range of applications, including mobile phones,
tablets, wearables, notebooks, and IP network cameras.
When used as a front-facing camera solution in
smartphones, tablets and notebooks, the OV7676 also
supports video-in-video functionality, allowing users to
record and stitch together video being recorded
simultaneously by the front- and rear-facing cameras.
Utilizing OmniVision's 3-micron OmniPixel3-HS™
technology, the OV7676 achieves best-in-class lowlight sensitivity, signal-to-noise ratio, full-well capacity
(FWC), quantum efficiency and low-power consumption.
The OV7676 supports serial peripheral interface (SPI)
and digital video port (DVP) interface customization for
both smartphone and feature phone platforms.
The OV7676 fits into a 2.73 x 2.47 mm chip-scale
package (CSP).
