1. A sensor comprising:
- a light detector for dividing light in an environment into optical zones and detecting light from the optical zones;
a processor coupled to the light detector, wherein the processor is configured to determine spatial and temporal characteristics of the detected light, including a rate of change of an illumination level in the optical zones over time; and
a memory coupled to the processor for storing the spatial and temporal characteristics of the detected light and the rate of change of the illumination level in the optical zones over time as historic light readings.

11. A method for detecting light, comprising:
-
detecting light from an environment by dividing the light into optical zones; determining spatial and temporal characteristics of the detected light, including a rate of change of an illumination level in the optical zones over time; storing the spatial and temporal characteristics of the detected light and the rate of change of the illumination level in the optical zones over time as historic light readings for the optical zones; and determining a luminosity of a light source based on the historic light readings. - View Dependent Claims (12, 13, 18)
