Abstract
A depth detection apparatus that detects depth information on a depth to an object on the basis of first and second signals corresponding to first and second pupil regions of an exit pupil, including: a first calculation unit that calculates a first shift amount between the first and second signals; a signal processing unit that generates a corrected signal by performing filter processing on at least one of the first and second signals, the filter processing being performed to relatively displace the first and second signals by a displacement amount corresponding to the first shift amount; and a second calculation unit that calculates a second shift amount between the filtered first and second signals or between signals, one of which is filtered in the filter processing and the other one of which is unfiltered.
