1. An image capture apparatus, comprising:
an image sensor that captures a subject image formed via a lens and outputs an image; and
at least one processor or circuit configured to function as:
a detection unit configured to detect flicker from the image output from the image sensor; and
a control unit configured, in a case where, in an image capture time period in which images of a subject are being captured for flicker detection by the image sensor, a drive operation of the lens is performed that causes a change in an amount of light received by the image sensor, to change a method for detecting flicker via the detection unit,
wherein the control unit switches between a first method for detecting flicker in which flicker is detected using a plurality of images for flicker detection and a second method for detecting flicker in which flicker is detected using an image for live view, and
wherein the control unit selects the first method in a case where a drive speed of a diaphragm of the lens is equal to or less than a predetermined threshold and selects the second method in a case where the drive speed is higher than the predetermined threshold.
