Abstract
A range finder wherein the quantization of analog outputs from light receptor elements for converting an optical image into an electrical signal is accomplished by comparing the outputs from at least two of the light receptor elements in each group, by dividing the outputs into the following three cases: one output is greater than the other; both are equal; and one is smaller than the other.
