Claim 17:
18. An image capturing apparatus comprising:
an image sensor;
at least one processor configured to perform operations of the following units:
a flicker detection unit configured to detect flicker that is a periodic change in a light amount of an object;
a determination unit configured to determine a first shutter speed based on a light amount change frequency of the flicker detected by the flicker detection unit, the first shutter speed being based on a reciprocal of the light amount change frequency of the detected flicker;
a selection unit configured to select a second shutter speed as a candidate in capturing an image of the object with reduced effect of the flicker based on the first shutter speed determined by the determination unit; and
a notification unit configured to, if a third shutter speed of the image capturing apparatus set in advance and the second shutter speed are different, make a notification of information about the second shutter speed.
