a lead-free
package
The OV7740 (color) CameraChip™ sensor is a low power,
high sensitivity VGA CMOS image sensor that provides
the full functionality of a single-chip VGA camera in a
small footprint.
Using OmniVision's proprietary OmniPixel3-HS™
technology, the 1/5-inch OV7740 boasts a best-in-class
low light sensitivity of 6800mV/(Lux-sec), making it ideal
for integrated notebook cameras, as well as stand-alone
PC webcams, security and gaming applications.
The OV7740 can operate at 60 frames per second (fps) in
VGA resolution and 120 fps in QVGA resolution with
complete user control over image quality, formatting and
output data transfer. It supports a digital video parallel
port, and provides full-frame, sub-sampled, windowed or
scaled 8-bit/10-bit RAW RGB and 8-bit YUV images.
All required image processing functions including
exposure control, gamma, white balance, color saturation,
hue control, defective pixel canceling, noise canceling,
etc., are programmable through the serial camera control
bus (SCCB) interface.
In addition, the OV7740 uses proprietary technology to
improve image quality by reducing or eliminating common
lighting/electrical sources of image contamination, such
as fixed pattern noise and smearing, to produce a clean
and fully stable color image.
For storage purposes, the OV7740 also includes one-time
programmable (OTP) memory.
