Abstract:
Imagers reproduce an image by converting photons to a signal that is representative of the image. A sensor readout module reads reset and signal voltages corresponding to a plurality of integration times for each of a plurality of pixels. The sensor readout module is capable of determining whether the differences between reset and signal voltages corresponding to respective integration times indicate a saturation condition of the pixel. Accordingly, the sensor readout module may provide an output signal based on reset and signal voltages corresponding to an integration time that is less than an integration time for reset and signal voltages that indicate the saturation condition. A normalization module may normalize the output signal to correspond with a linear response curve.
