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.

A range finder comprising a first and second optical means for receiving light from an object through different optical paths to form object images on a predetermined focal plane; first and second light receptor arrays for generating first and second electric signals, respectively, corresponding to intensity of light of the image; each of said arrays comprising a plurality of elements; a plurality of first converter elements, each of which corresponds to one of said first receptor elements; a plurality of second converter elements, each of which corresponds to one of said second receptor elements; said first and second converter elements generating integrated signals when said first and second electric signals are integrated to a predetermined value; a plurality of first quantization means, each of which receives signals from two of said first converter elements; a plurality of second quantization means, each of which receives signals from two of said second converter elements; said two first converter elements corresponding to said two second converter elements; said first and second quantization means detecting timing of the generation of two integrated signals, whereby a three-value output is obtained as to which integrated signal is generated first or whether these two signals are generated substantially at the same time; and a measuring means for measuring a distance to the object by a correlation of the three-value outputs generated from the quantization means.
