Abstract
An apparatus sets a weighting of a first subject included in a predetermined first range to be larger than that of other subjects when a detected subject is included in a first range in an image, updates a target subject for the photometry of which the weighting is set to be larger after continuing a state where the weighting of the first subject is set to be larger for a predetermined time when the first subject goes out of a second range which is wider than the first range and when the first subject does not go out of a third range which is wider than the second range, and updates the target subject for the photometry of which the weighting is set to be larger in response that the first subject goes out of the third range.
Claims19
An apparatus comprising:
- a capturing unit configured to capture an image of a subject formed through an optical system and output an image;
- and
- at least one processor and a memory coupled to the processor storing instructions that when executed by the processor, cause the processor to function as:
- a photometry unit configured to perform a photometry for a target subject;
- a detection unit configured to detect a subject included in the output from the capturing unit;
- a setting unit configured to set a degree of weighting for the target subject for which the photometry is performed by the photometry unit;
- and
- a control unit configured to control an exposure based on a photometric result of the photometry unit,
- wherein the setting unit sets the weighting of a first subject included in a predetermined first range to be larger than that of other subjects when the detected subject is included in the first range in the image, updates the target subject for the photometry of which the weighting is set to be larger after continuing a state where the weighting of the first subject is set to be larger for a predetermined time when the first subject goes out of a second range which is wider than the first range and when the first subject does not go out of a third range which is wider than the second range, and updates the target subject for the photometry of which the weighting is set to be larger in response to the first subject going out of the third range.
A method of controlling an apparatus comprising:
- capturing an image of a subject formed through an optical system and outputting an image;
- detecting a subject included in the image;
- setting a degree of weighting for a target subject for a photometry;
- performing the photometry for the target subject;
- and
- controlling an exposure based on a photometric result of the photometry, wherein in the setting, when the detected subject is included in a predetermined first range in the image, the weighting of a first subject included in the first range is set to be larger than that of other subjects, when the first subject goes out of a second range which is wider than the first range and when the first subject does not go out of a third range which is wider than the second range, the target subject for the photometry for which the weighting is set to be larger is updated after continuing a state in which the weighting of the first subject is set to be larger for a predetermined time, and the target subject for which the weighting is set to be larger is updated in response to the first subject going out of the third range.
A non-transitory computer-readable storage medium storing a program that causes a computer to execute a method of controlling an apparatus comprising:
- capturing an image of a subject formed through an optical system and outputting an image;
- detecting a subject included in the image;
- setting a degree of weighting for a target subject for a photometry;
- performing the photometry for the target subject;
- and
- controlling an exposure based on a photometric result of the photometry, wherein in the setting, when the detected subject is included in a predetermined first range in the image, the weighting of a first subject included in the first range is set to be larger than that of other subjects, when the first subject goes out of a second range which is wider than the first range and when the first subject does not go out of a third range which is wider than the second range, the target subject for the photometry for which the weighting is set to be larger is updated after continuing a state in which the weighting of the first subject is set to be larger for a predetermined time, and the target subject for which the weighting is set to be larger is updated in response to the first subject going out of the third range.
