Abstract

See full text

The present invention relates to a distance measuring apparatus including an imaging device and a calculation unit calculating a distance to a subject on the basis of an electrical signal. The imaging device includes a signal acquisition unit that acquires a first electrical signal based on a beam that has passed through a first region off the center of the exit pupil in a predetermined direction; a second electrical signal based on a beam that has passed through a second region off the center of the exit pupil in a direction opposite to the predetermined direction; and a third electrical signal based on a beam that has passed through a region eccentric from the first region in the direction opposite to the predetermined direction. The calculation unit performs a signal correction process for generating a first corrected signal and a distance calculation process for calculating the distance.
