ABSTRACT:
First, a lens is supplied with a power supply LVDD. Then the state of a chip select signal CSL is input, and the processing waits until chip select signal CSL changes from HIGH.fwdarw.LOW.fwdarw.HIGH, that is, until communication preparation on the lens side is completed. When a microcomputer on the lens side is reset and started, the lens side outputs a communication enable signal and thus the time from mounting of the lens to starting of a communication can be reduced. Thus, a lens-exchangeable camera can be provided capable of starting a BL communication in the shortest time depending on the lens.
