Abstract
An image capturing apparatus comprises a communication unit that performs wireless communication with a plurality of light emitting apparatuses and a control unit that switches to a first communication state in which the plurality of light emitting apparatuses and the image capturing apparatus perform wireless communication at predetermined communication intervals, and a second communication state in which a predetermined light emitting apparatus of the plurality of light emitting apparatuses and the image capturing apparatus perform wireless communication at predetermined communication intervals and the predetermined light emitting apparatus and a light emitting apparatus other than the predetermined light emitting apparatus perform wireless communication at variable communication intervals. The control unit switches to the first communication state or the second communication state according to an operational state of the image capturing apparatus.
