A sensor and method for widening a dynamic range of sensor circuitry for sensing energy, such as light energy. The sensor circuitry includes a sensor and recharge circuitry for sharing additional charge with the sensor as needed during an integration period. Readout circuitry is provided to read out, after the integration period, the sense voltage remaining across the sensor and recharge information indicating whether the recharge circuitry shared charge with the sensor during the integration period. The sense voltage and recharge information read out of the sensor circuitry is used in a function to determine the total amount of energy sensed by the sensor during the integration period.
