Image formau00c7u00e7o apparatus, methods of controlling a formau00c7u00e7o apparatus of image, and a acessu00e0rio, storage medium readable by computer, and system.An apparatus for formation of image to which an accessory is separavelmente set includes an imaging unit configured to convert an object image into an electrical signal, a generation unit configured to generate a signal, a vertical synchronization signal.That is synchronized with a temponzau00e7u00e3o exposure of the imaging unit and outputs the vertical synchronization signal is generated, a control unit configured to control communication with an accessory based on the vertical synchronization signal, a first terminal con You figured for sending a clock signal generated by the control unit to the accessory.And a second terminal configured to communicate data with the accessory based on the control signal, the control unit controls a signal level at the first terminal to a predetermined level when the communication of the data ends, and then changes the signal level of the synchronizes Tion with the issuance of the vertical synchronization signal.
