a lead-free
package
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 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.
