초록

A range detecting method and apparatus of a construction, in which first and second images of an object to be formed by a range finding optical system with a relative positional parallax corresponding to the object distance are scanned purely electrically by the use of one or more photo-sensor arrays, then analog image element signals concerning these first and second images obtained at this time are sequentially converted into two-value signals, after which the two-value signals are stored, as inputs, in first and second digital storing device where the...

청구항

A method of detecting a range of an object comprising the steps of: (a) deriving first and second images of said object along different sight lines; (b) electrically sensing said first and second images to produce an electrical analog signal for each image element of said first and second images; (c) quantizing said electrical analog signal to produce quantized data for each image element of the first and second images; (d) storing the quantized data on N successive elements of the first image and successively storing, on one set-by-set basis, the quanti...
