Abstract

A method and apparatus for measuring the output of the measurement signal output by an optical sensor, for determining the intensity of the lights incident on the sensors. A plurality of setting values corresponding in a functional relationship to a plurality of estimated light intensity values being stored, prior to the measurement, in a memory. An address specifying means for causing the memory to output one of the plurality of setting values prestored therein during the time the address is specified. A count means for counting clock pulses with a predetermined period during the time duration of the measurement signal. A detecting means for detecting a comparison between the count value of the clock pulses and the setting value prestored in the memory and then causing the address specifying means to specify a new address in the memory in response to the detection result.
