Assignee: CANON KABUSHIKI KAISHA
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An image capturing apparatus comprising:
an image sensor; and
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; and
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,
wherein the determination unit is configured to, if a third shutter speed of the image capturing apparatus is set in advance, determine a closer one of shutter speeds to the third shutter speed than the other shutter speeds as the first shutter speed, the shutter speeds being integer multiples of a shutter speed that is the reciprocal of the light amount change frequency of the flicker detected by the flicker detection unit, and
wherein the selection unit is configured to select one of settable shutter speeds of the image capturing apparatus as the second shutter speed, the selected one of settable shutter speeds having a smaller difference from the first shutter speed than the others shutter speeds.
