Abstract
An image capturing apparatus that controls a light emitting apparatus, performs communication with the light emitting apparatus at predetermined intervals, decides information regarding a period of time remaining before the light emitting apparatus emits light, based on the remaining time to exposure and a period of time from when the remaining time starts decreasing, to when the wireless communication unit performs a first wireless communication thereafter, and performs control so that the information regarding the decided period of time is transmitted to the light emitting apparatus through the first wireless communication with the light emitting apparatus. In a case where transmission and reception of the information regarding the period of time between the image capturing apparatus and the light emitting apparatus fail, the image capturing apparatus performs control so that the information regarding the period of time is re-transmitted.
