Patent ID: 7280148

Claim:
An optical control system comprising: a control unit comprising a command signal generation section, which generates a command signal in response to operation of an operating member, and a first connector, which is connected to a communication cable and outputs the command signal from a first terminal thereof via the communication cable; and an optical apparatus comprising an optical adjusting member, which is movable to perform an optical action, an actuator driving the optical adjusting member, a second connector which is connected to the communication cable, a first control section, which controls the actuator based on the command signal input via a second terminal of the second connector from the control unit, a second control section, which controls the actuator based on predetermined information, and a control switching section, which selects, from the first and the second control sections, the control section controlling the driving of the actuator; wherein the control unit comprises an output switching section, which is switchable between a first state, in which the command signal from the command signal generation section is output via the first terminal of the first connector, and a second state, in which a switching signal for selecting the second control section, the voltage level of the switching signal being different from that of the command signal, is output from the first terminal; and wherein the control switching section of the optical apparatus selects the first control section in response to input of the command signal, and selects the second control section in response to the switching signal, which is input from the second terminal of the second connector.
