Method of driving multiple flash rangefinder

摘要

A method of driving the light-emitting devices of a multiple flash rangefinder for use in an autofocus camera in which the rangefinder includes a light-receiving device and an arithmetic processing unit that calculates the distance to the subject from the output signal from the light-receiving device. The light-emitting devices are lit up successively one at a time in such a way that each device emits momentarily and the series of operations is repeated several times.
