Abstract
An image processing apparatus comprising: a first obtaining unit configured to obtain a focal length of an imaging optical system; a second obtaining unit configured to obtain a distance to a subject; a setting unit configured to set a movable range for a correction unit configured to correct camera shake, based on the focal length and the distance to a subject; and a calculation unit configured to calculate a correction amount for correcting the camera shake within the movable range that was set by the setting unit, based on a camera shake signal from a camera shake detection unit configured to detect camera shake and output the camera shake signal.
Claims6
An image processing apparatus comprising:
- one or more processors programmed to perform operations of following units:
- a first obtaining unit configured to obtain a focal length of an imaging optical system;
- a second obtaining unit configured to obtain a distance to a subject;
- a setting unit configured to set a movable range for a correction unit configured to correct camera shake, based on the focal length and the distance to a subject;
- and
- a calculation unit configured to calculate a correction amount for correcting the camera shake within the movable range that was set by the setting unit, based on a camera shake signal from a camera shake sensor configured to detect camera shake and output the camera shake signal,
- wherein the setting unit sets the movable range such that, in a case where the distance to a subject is less than or equal to a predetermined threshold value, the movable range continuously becomes narrower as the distance to a subject becomes shorter.
An image capturing apparatus comprising:
- an image sensor;
- and
- an image processing apparatus comprising one or more processors programmed to perform operations of following units:
- a first obtaining unit configured to obtain a focal length of an imaging optical system;
- a second obtaining unit configured to obtain a distance to a subject;
- a setting unit configured to set a movable range for a correction unit configured to correct camera shake, based on the focal length and the distance to a subject;
- and
- a calculation unit configured to calculate a correction amount for correcting the camera shake within the movable range that was set by the setting unit, based on a camera shake signal from a camera shake sensor configured to detect camera shake and output the camera shake signal,
- wherein the setting unit sets the movable range such that, in a case where the distance to a subject is less than or equal to a predetermined threshold value, the movable range continuously becomes narrower as the distance to a subject becomes shorter.
A method of controlling an image processing apparatus comprising:
- obtaining a focal length of an imaging optical system;
- obtaining a distance to a subject;
- setting a movable range for a correction unit configured to correct camera shake, based on the focal length and the distance to a subject;
- and
- calculating a correction amount for correcting the camera shake within the set movable range, based on a camera shake signal from a camera shake sensor configured to detect camera shake and output the camera shake signal,
- wherein, upon setting the movable range, in a case where the distance to a subject is less than or equal to a predetermined threshold value, the movable range is set so as to continuously become narrower as the distance to a subject becomes shorter.
