Abstract

See full text

A depth estimation apparatus including: an imaging device which generates a first image signal and a second image signal by imaging an object at different phases; a storage unit configured to store model data defining a relationship between (i) lens blur and phase difference of the object in images and (ii) position of the object in the images in the depth axis; and a detecting unit configured to detect a position of the object in the depth axis from the first image signal and the second image signal, using the model data, wherein a phase difference between the first image signal and the second image signal is smaller than or equal to 15% in terms of a base line length.
