OV7725 VGA product brief
high performance, all-digital VGA camera solution
available in
a lead-free
package
The OV7725 CameraChip™ sensor is a highperformance 1/4 inch, single-chip VGA camera
and image processor in a small footprint
package. Operating at full functionality, the
OV7725 meets all pc multimedia and
cameraphone market requirements in terms of
performance, quality and reliability. The lowpower OV7725 excels in low light conditions and
can operate in a wide temperature range, from
-20ºC to +70ºC.
The OV7725 incorporates a 640 x 480 image array, capable
of operating at 60 frames per second in VGA mode with
complete user control over image quality, formatting and
output data transfer.
The OV7725 provides full-frame, sub-sampled or windowed
8-bit/10-bit images in a wide range of formats, controlled
through the serial camera control bus (SCCB) interface. The
OV7725 possesses all required camera processing functions
including exposure control, gamma, white balance, color
saturation, hue control and more. These functions are also
programmable through the SCCB interface.
