OmniVision Introduces 5 MP CameraChip Sensor for Video-Centric Smartphones

OmniVision Technologies, a developer of sophisticated digital imaging solutions, has launched a 5 MP CameraChip sensor, the OV5680. The sensor utilizes the new 1.75-ìm OmniBSI-2 pixel.

The OV5680 sensor offers 1080p high definition (HD) video with a high frame rate and high sensitivity and quality. It utilizes an integrated scaler that allows capture of video at 30 fps for shutterless designs without lag. It is designed for continuous shooting. In 1080p HD mode for video, the scaler maintains a complete field of view for electronic image stabilization.

The OV5680 sensor enables video capture of 720p @ 60 fps through its 2 x 2 binning functionality that has a post-binning re-sampling filter. The sensor has the capability to remove image artifacts that occur around edges. It can also minimize spatial artifacts. These features enable the OV5680 sensor to provide crisp and clean color images that are required for high quality HD video. The sensor can also meet the requirements for three-dimensional video capture by synchronizing the frame and exposure for stereo cameras.

OmniVision has used a 300 mm copper process with design rules of 65 nm to build the new 1.75-ìm OmniBSI-2 pixel. This reduces the consumption of power and is better than the first generation of OmniBSI pixels in terms of quality and performance. The OmniBSI-2 pixel also provides an increase in full-well capacity of 50%, improvement in low-light performance of 20% and an enhancement in peak quantum efficiency of 20%.

The 1/3.2" OV5680 sensor reduces the performance gap between dedicated digital video cameras and mobile phone cameras/smart phones. It has a standard 2-lane MIPI interface and can fit into 8.5 x 8.5 x 6 mm modules. OmniVision expects to commence mass production of the product in 2012.
