PROBLEM TO BE SOLVED: To change the driving speed of a lens in accordance with the time elapsed after finishing the operation of an operation member for adjusting a lens focus. SOLUTION: An image input device is equipped with an imaging device 2, a processing circuit 3, a D/A conversion circuit 8, a control part 5, the operating members 6 and 7, a clocking circuit 4, a CPU 10, a motor 201 and a driving circuit 200. The circuit 4 clocks the time elapsed after finishing the operation of the members 6 and 7. When an operation signal is inputted in the control part 5 from either the member 6 or 7, the CPU 10 decides the digital value of a control signal in accordance with the clocked time. When the control signal is inputted in the circuit 200 from the control part 5, the circuit 200 drives the motor 201 at speed in accordance with the digital value. |
