Researchers at Oxford University have developed an image pixel design with a high dynamic range and improved performance in low light intensity for use in sensors in automotive, industrial, security and consumer products.

The market for electronic imaging in devices including digital cameras, mobile telephones, computers and other sensors has spurred the development of single chip CMOS cameras.

The vast majority of these cameras create an image by integrating the photocurrent within each pixel for a predetermined period. This creates a voltage that is proportional to the photon flux at the corresponding pixel, a simple imaging strategy that achieves a large enough dynamic range for scenes with relatively uniform levels of...
