Abstract
An image capture apparatus that allows the user to easily change the brightness of an image that is shot while using automatic exposure control is disclosed. The image capture apparatus comprises a setting unit configured to be able to set a reference value of proper exposure. The image capture apparatus determines exposure conditions based on the luminance information and the reference value, wherein the reference value is a value used as a reference exposure value from which exposure conditions are varied in an exposure compensation.
Claims18
An image capture apparatus comprising:
- at least one processor that functions, when executes a program stored in a memory, as:
- a setting unit configured to be able to set a reference value of proper exposure;
- an obtaining unit configured to obtain luminance information of a subject;
- a determination unit configured to determine exposure conditions based on the luminance information and the reference value;
- and
- a control unit configured to control exposure conditions that include an exposure index of the image capture apparatus,
- wherein the reference value is a value used as a reference exposure value from which exposure conditions are varied in an exposure compensation, and
- wherein, in a case where the reference value is changed in a state where the exposure conditions have been manually set, the control unit changes the exposure index of the image capture apparatus so as to suppress an influence of the change in the reference value on brightness of an image that is acquired through shooting.
A method of controlling an image capture apparatus, comprising:
- setting a reference value of proper exposure;
- obtaining luminance information of a subject;
- determining exposure conditions based on the luminance information and the reference value;
- and
- controlling exposure conditions that include an exposure index of the image capture apparatus,
- wherein the reference value is a value used as a reference exposure value from which exposure conditions are varied in an exposure compensation, and
- wherein, in a case where the reference value is changed in a state where the exposure conditions have been manually set, the controlling changes the exposure index of the image capture apparatus so as to suppress an influence of the change in the reference value on brightness of an image that is acquired through shooting.
A non-transitory computer-readable storage medium storing a computer-executable program for executing a method of controlling an image capture apparatus, wherein the method comprises:
- setting a reference value of proper exposure;
- obtaining luminance information of a subject;
- determining exposure conditions based on the luminance information and the reference value;
- and
- controlling exposure conditions that include an exposure index of the image capture apparatus,
- wherein the reference value is a value used as a reference exposure value from which exposure conditions are varied in an exposure compensation, and
- wherein, in a case where the reference value is changed in a state where the exposure conditions have been manually set, the controlling changes the exposure index of the image capture apparatus so as to suppress an influence of the change in the reference value on brightness of an image that is acquired through shooting.
