Light and/or infrared sensor unit sensitivity correcting method, involves forming address of correction memory, and providing stored and corrected data value for further processing based on memory addressing

摘要

The method involves providing a correction memory for providing desired output value for each sensor unit and possible digital sensor conditions. The memory is described with the corrected data for each sensor unit and each possible condition. The address for the correction memory is formed from the address of the sensor unit and the actual digital measurement value. The stored and corrected data value for further processing is provided according to the addressing of the memory.
