ABSTRACT:
Methods, systems and apparatuses proving a high dynamic range imager. Multiple photosensor integration periods are used to capture pixel signal information. A transistor gate is used to remove electrons from the photosensor between the two successive integration periods providing a non-linear pixel response characteristic having a knee point. Each pixel is calibrated for the knee point which is used during adjustment of the pixel output signal. Each pixel may also be calibrated with an arbitrary signal response curve for multiple light intensities.
