PROBLEM TO BE SOLVED: To achieve optimal control constantly without requiring a photographer to care of a specification of current capacity of a television camera or an auxiliary power source and a change caused by a situation of use. SOLUTION: Whether or not a driving command of a wiper that is an option member is inputted by a wiper driving command input unit is determined in S104, and in the case that the wiper driving command is inputted, processing is shifted to S105 to perform wiper drive control, but in the case that the wiper driving command is not inputted, processing is shifted to S106. Whether or not the wiper is being driven is determined in S106, and in the case that the wiper is being driven, processing is shifted to S107, but in the case that the wiper is not being driven, processing is shifted to S113. Whether or not information about current capacitance that can be supplied to a television lens unit 1 is outputted from a television camera unit 2 is determined in S107. At the same time, the information about the current capacitance is monitored in S107. As a result, In the case that the information about the current capacitance is not outputted or the current capacitance is a little, processing is shifted to S108 to stop drive control of a focus lens and a zoom lens.
