OV7695 VGA Ultra-Compact Cost-Effective Secondary Camera

Ultra-Compact, Cost-Effective Secondary Camera Solution for Smartphones

and Tablets

The OV7695 is a high-performance CameraChip™ sensor that utilizes OMNIVISION’s new OmniBSI™+ pixel architecture to deliver high quality VGA video at 30 frames per second. At just 2.4 mm x 2.3 mm, the cost-competitive OV7695 is a highly attractive solution for front-facing cameras in smartphones and tablets.

The 1/13-inch VGA sensor is built on a 1.75-micron OmniBSI™+ pixel, which has a significantly lower level of noise when compared with traditional FSI pixel architectures. The result is a dramatic improvement in dynamic range, which translates into higher quality color video. Using proprietary technology to improve image quality, the OV7695 reduces or eliminates common sources of image contamination such as fixed pattern noise and smearing to produce a clean, stable color image.

The sensor provides full-framed, sub-sampled and cropped images in YUV422 format via a one-lane MIPI interface. All required image processing functions, including exposure control, gamma, white balance, color saturation, defective pixel canceling, and noise canceling are programmable through the serial camera control bus (SCCB) interface.
