<P>PROBLEM TO BE SOLVED: To suppress driving noise without transmitting a large amount of information on the driving speed of an actuator between a lens device and an imaging apparatus. <P>SOLUTION: A lens device 2 is detachably attached to an imaging apparatus 1 and can communicate with the imaging apparatus. The lens device includes: an actuator 28 which moves an optical member 22 and whose driving speed is variable; a lens control part 26 for controlling the driving of the actuator; and a driving noise memory 36 for storing driving noise information on driving noise generated when the actuator is driven and varying in response to the change in the driving speed of the actuator. The lens control part receives information on an allowable value of the driving noise from the imaging apparatus, calculates an upper limit value of the driving speed of the actuator by using the allowable value and the driving noise information, and transmitting the upper limit value of the driving speed to the imaging apparatus to cause the imaging apparatus to determine the driving speed of the actuator equal to or lower than the upper limit value of the driving speed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
