Abstract
In order to provide a range measurement apparatus which enables an accurate distance measurement while an anti-vibration mechanism is operated, the range measurement apparatus includes an image information acquisition unit configured to acquire an image captured by an image pickup optical system having an anti-vibration optical system, a distance information acquisition unit configured to acquire distance information regarding a distance to a subject based on the image, and a distance correction unit configured to correct the distance information based on aberration information according to a driving amount of the anti-vibration optical system.
Claims17
A range measurement apparatus comprising:
- at least one processor or circuit configured to function as a plurality of units comprising:
- (1) an image information acquisition unit configured to acquire an image of a subject captured by an image pickup optical system, the image pickup optical system including an anti-vibration optical system and an image sensor;
- (2) a distance information acquisition unit configured to acquire distance information regarding a distance from the image sensor to the subject based on the image;
- and
- (3) a distance correction unit configured to correct the distance information based on aberration information according to a driving amount and a driving direction of the anti-vibration optical system,
- wherein the driving direction corresponds to an angle with respect to a detecting direction.
A non-transitory computer-readable storage medium configured to store a computer program for a range measurement apparatus to execute a method comprising the following steps:
- an image information acquisition step of acquiring an image of a subject captured by an image pickup optical system, the image pickup optical system including an anti-vibration optical system and an image sensor;
- a distance information acquisition step of acquiring distance information regarding a distance from the image sensor to the subject based on the image;
- and
- a distance correction step of correcting the distance information based on aberration information according to a driving amount and a driving direction of the anti-vibration optical system,
- wherein the driving direction corresponds to an angle with respect to a detecting direction.
