Claim Text:
1. An accessory connectable to an image capture apparatus, comprising: a first signal terminal which is electrically connected to a terminal provided to an accessory shoe of a connected image capture apparatus so as to communicate with the connected image capture apparatus, a signal level of a signal going through said first signal terminal corresponding to information to be communicated via said first signal terminal; a second signal terminal used to make a serial communication with the connected image capture apparatus, which is different from said first signal terminal; an activation signal generation unit configured to generate an activation signal required to change the connected image capture apparatus from a first state to a second state, wherein the first state is a state where the serial communication via the second signal terminal is not executable, and the second state is a state where the serial communication via the second signal terminal is executable; a control unit configured to control to output the activation signal to the connected image capture apparatus via said first signal terminal; and a determination unit configured to determine a type of the connected image capture apparatus by using said first signal terminal, wherein when said determination unit determines that the connected image capture apparatus is a specific image capture apparatus, said control unit controls to output the activation signal to the connected image capture apparatus via said first signal terminal.
