Higher Performance, Feature Rich VGA Sensor
to Support Fast Growing Emerging Markets
OV7675 VGA product brief
lead free
available in
a lead-free
package
The OV7675 is a high performance VGA sensor designed
specifically to address growing demand for consumer
electronics from emerging markets. Its small optical format
enables ultra-thin camera modules, which, combined with
its excellent low-light performance, make it a very
attractive solution for entry-level and mainstream mobile
phones, notebooks, netbooks and webcams.
The OV7675 is a low-voltage color CMOS image sensor
that supports the full functionality of a single chip VGA
(640 x 480) camera in a small footprint package. The
1/9-inch OV7675 uses a unique 2.5-micron
OmniPixel3-HS™ pixel design, which allows it to offer
best-in-class low-light sensitivity (1800 mV/lux-sec),
significantly reduced noise and outstanding color
reproduction.
The OV7675 provides full-frame, sub-sampled, windowed
images in VGA, QVGA and QQVGA formats via the control
of the serial camera control bus (SCCB) interface. Its image
array is capable of operating at up to 30 frames per second
(fps) in full VGA resolution with complete user control over
image quality, formatting and output data transfer.
All required image processing functions, including exposure
control, gamma, white balance, color saturation, hue
control, defective pixel canceling, noise canceling are
programmable through the SCCB interface. In addition,
OmniVision image sensors use proprietary sensor
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, fully stable color image.
