Imaging array with non-linear light response

Image Number 10 for United States Patent #8130294.

An imaging array and method for capturing an image utilizing the same are disclosed. The imaging array includes an array of pixel sensors in which each pixel includes a dual-ported photodiode or photogate and a charge conversion circuit. The charge conversion circuit generates a voltage signal that is a function of a charge on the dual-ported photodiode. The controller applies a potential that varies over the exposure to the second gates in the dual-ported photodiodes, each second port passing charge stored in the photodiode connected to the second port when a potential in the photodiode exceeds the applied potential. The potential is chosen such that charge flows through the second gates of pixel sensors that are exposed to light intensities greater than a first threshold intensity during the exposure.
