Abstract
An image capturing apparatus includes: a system selector configured to select either one of a focus control of a contrast system in which a wobbling motion is performed for detection and a focus control of a different system that is different from the focus control of the contrast system; and a controller configured to set a first wobbling amount for the focus control of the different system to be smaller than a second wobbling amount for the focus control of the contrast system.
Claims14
An image capturing apparatus, comprising:
- a system selector configured to select either one of a focus control of a contrast system in which a wobbling motion is performed for detection and a focus control of a different system that is different from the focus control of the contrast system;
- and
- a controller configured to set a first wobbling amount for the focus control of the different system to be smaller than a second wobbling amount for the focus control of the contrast system,
- wherein the focus control of the different system is a focus control of a phase difference system, and
- wherein the system selector is configured to select, based on a result of detection for the focus control of the phase difference system, either one of the focus control of the contrast system and the focus control of the phase difference system.
A method of controlling an image capturing apparatus, comprising the steps of:
- selecting, by a system selector, either one of a focus control of a contrast system in which a wobbling motion is performed for detection and a focus control of a different system that is different from the focus control of the contrast system;
- and
- setting, by a controller, a first wobbling amount for the focus control of the different system to be smaller than a second wobbling amount for the focus control of the contrast system,
- wherein the focus control of the different system is a focus control of a phase difference system, and
- wherein the selecting step includes selecting, based on a result of detection for the focus control of the phase difference system, either one of the focus control of the contrast system and the focus control of the phase difference system.
A non-transitory computer-readable medium storing a set of computer-executable instructions causing a computer to execute a method of controlling an image capturing apparatus, the method comprising the steps of:
- selecting either one of a focus control of a contrast system in which a wobbling motion is performed for detection and a focus control of a different system that is different from the focus control of the contrast system;
- and
- setting a first wobbling amount for the focus control of the different system to be smaller than a second wobbling amount for the focus control of the contrast system,
- wherein the focus control of the different system is a focus control of a phase difference system, and
- wherein the selecting step includes selecting, based on a result of detection for the focus control of the phase difference system, either one of the focus control of the contrast system and the focus control of the phase difference system.
