OV7680 VGA product brief
available in a lead-free package
1/10 inch VGA image sensor for low cost, ultra-slim camera phones
The OV7680 is a single-chip, high-performance VGA image sensor with an optical format of 1/10 inch. Using a 2.2 m x 2.2 m pixel built on OmniPixel2TM 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. 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.
The OV7680 employs OmniVision's proprietary OmniPixel2 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.
