Method and apparatus for controlling interchangeable lens system camera having reduced delay time to detect lens and accessory device information

摘要

A method of controlling an accessory device which is connected with a body unit of an interchangeable lens system camera is described. The method includes: receiving identification information of a first device from the first device through a first communication path that passes through a digital signal processing unit of the accessory device; generating combination information by adding identification information of the accessory device to the identification information of the first device; transmitting the combination information to a second device through the first communication path; and when receiving a switching signal from the second device, switching the first communication path to a second communication path that does not pass through the digital signal processing unit of the accessory device.
