An image pickup apparatus (118) being constructed to detachably mount a lens unit (117) includes an image pickup means (106) for accumulating charge in synchronization with a vertical synchronizing signal, and control means (116) for generating control information for each of a plurality of optical members (102, 103, 105) of the mounted lens unit (117) and for communicating the control information with the lens unit. The control means is capable of communicating with the lens unit in synchronization with the vertical synchronizing signal. The control means performs a first communication in synchronization with the vertical synchronizing signal, and then performs a second communication before a next first communication that is performed in synchronization with a next vertical synchronizing signal. The first communication and the second communication are predetermined packet communications in which optical members to be controlled among the plurality of optical members are different from each other. |
