Image capturing apparatus capable of effectively reducing the influence of noise caused by an auxiliary device attached to the imaging apparatus

摘要

An image capture apparatus determines a maximum power to be supplied from the image capture apparatus to an auxiliary device detachably attached to the image capture apparatus, based on information regarding a distance between a noise source included in the auxiliary device and an image sensor included in the image capture apparatus. The image capture apparatus then supplies power to the auxiliary device, without exceeding the determined maximum power and thereby effectively reduces the influence of noise caused by the auxiliary device, on the image sensor and a captured image.
