product brief  
OV7680VGA  
1/10 inch VGA image sensor for low cost,  
ultra-slim camera phones  
available in  
a lead-free  
package  
The OV7680 employs OmniVision’s proprietary OmniPixel2  
The OV7680 is a single-chip, high-performance VGA  
image sensor with an optical format of 1/10 inch.  
Using a 2.2 μm x 2.2 μm pixel built on OmniPixel2™  
technology, the OV7680 enables ultra thin camera  
modules of just 4.5 x 4.5 x 3.17 mm. This is a critical  
characteristic for slim camera phones and notebook  
applications where the camera module can be no  
thicker than the LCD housing.  
architecture, which significantly increases signal-to-noise  
ratio and delivers exceptional low-light performance.  
Operating at a low voltage, the OV7680 image sensor  
provides the full functionality of a single chip VGA camera and  
image processor in a small footprint package. This includes  
full-frame, sub-sampled or windowed 8-bit images in a wide  
range of formats controlled through a serial camera control  
bus (SCCB) interface.  
The OV7680 can operate at 30 frames per second (fps) in  
VGA with full user control over image quality, formatting and  
output data transfer. As part of OmniVision’s next generation  
of image sensors, the OV7680 delivers low-noise, low-cost,  
low-power consumption, high integration, wide dynamic range  
and excellent low-light performance.  
The OV7680’s ultra thin module size allows for a  
1-plastic lens design. Additionally, the OV7680’s  
unique non-linear micro lens shift technology allows  
for a reduction in the distance between sensor and  
lens; reducing module height even further without loss  
of image quality or camera performance.
