測距装置および測距方法
Document Type and Number:
Japanese Patent JP7057090
Kind Code:
B2
Abstract:
A distance measuring apparatus includes: an image pickup element in which a plurality of pixels receives light of an image are two-dimensionally arrayed; and an acquiring unit acquires information relating to a distance to an object based on an output signal of the image pickup element which each pixel line is constituted by pixels which receive beams passing through a same pupil region of the imaging optical system, and wherein the acquiring unit (1) acquires a first image displacement amount from output signals of at least two pixel lines which receive beams passing through a same pupil region, (2) acquires a second image displacement amount from output signals of at least two pixel lines which receive beams passing through different pupil regions, and (3) acquires the information relating to the distance to the object based on the first image displacement amount and the second image displacement amount.
