Abstract:
An image sensor can respond to light either linearly or logarithmically in order to achieve flexible and high contrast performance. This is made possible by using a programmable lookup table, or an array of numbers, that represents control parameter values of the image sensor. The control parameter values in the lookup table are programmable and could be kept constant, increase linearly, or non-linearly, between consecutive indexes. Photodiode control circuitry is used to adapt the response of the photodiodes in the image sensor depending on the lighting impacting upon the image sensor.

Claim (Index 1):
An active-pixel image sensor, comprising:\n a lookup table (LUT) having a plurality of index positions and having stored therein a plurality of control parameter values; a plurality of photodiodes; and photodiode control circuitry arranged to adapt a response of the plurality of photodiodes to light in dependence on the control parameter values stored in the LUT, wherein the plurality of control parameter values are programmable and define a sensitivity response function of the active-pixel image sensor to light.
