Abstract
Briefly, in accordance with one embodiment of the invention, a higher dynamic range image sensor may be implemented by comparing a voltage across the sensor to a threshold voltage during image capture. At the threshold voltage, a count may be registered and the image sensor may be reset for continued image capture until an exposure is complete. A final image signal may be obtained by multiplying the threshold voltage by the number of counts registered and adding the final image sensor voltage.
