Abstract
Official abstract text for this publication.
An imaging apparatus to which an accessory is detachably attached, said accessory including an optical member, includes a signal generation unit configured to generate a vertical synchronizing signal and output the generated vertical synchronizing signal, an imaging unit configured to accumulate charges in synchronization with the vertical synchronizing signal and output an imaging signal, a control unit configured to generate a clock signal and control data communication with the accessory based on the clock signal, a first terminal for sending the clock signal to the accessory, and a second terminal for communicating data with the accessory, in which the control unit, after the data communication via the second terminal, notifies timing at which the vertical synchronizing signal is output using the clock signal via the first terminal by changing a signal level of the first terminal after a lapse of a predetermined time while the signal level is kept at a predetermined level, and controls the accessory to drive the optical member based on the timing.
