Technical content
The OV6680 is a single-chip, high-performance SquareGA™ (SGA™) resolution (400x400) CameraChip™ sensor that incorporates all the functionality of a camera and image processor in one small footprint package. Using a 3.6 μm x 3.6 μm pixel built on OmniPixel2™ technology utilizing a 0.18 μm CMOS process, the OV6680 has outstanding low-light performance to accommodate any lighting condition. The OV6680 color camera is an excellent candidate for secondary handset cameras for 2-way video conferencing over 3G networks. This is enabled by its ultra small module design (5x5x3.0 mm) and superior low-light performance. Low light performance is most critical for video conferencing applications because LCD screens emit very little light (about 1 lux) and indoor environments tend to be less bright. available in a lead-free package OV6680SGA optimal low-light sensitivity and pixel performance for video conferencing cameras in 3G mobile phones product brief Additionally, by outperforming smaller VGAs, it is also an excellent alternative as a primary camera for low cost mobile phones. The OV6680 provides full-frame, sub-sampled or windowed 8-bit images in a wide range of formats, controlled through the Serial Camera Control Bus (SCCB) interface. The OV6680 operates at 30 frames per second (fps) in SGA resolution (400x400 pixels) with complete user control over image quality, formatting and output data. Enabling a 400x400 pixel output allows users to perform image stabilization functions with post processing. All the required image processing functions such as exposure control, gamma, white balance, color saturation and hue control are also programmable through the SCCB interface.
