ABSTRACT:
There is provided a vibration reduction camera which includes an operation portion that operates based on electric power, and a vibration reduction driving portion, and can reduce consumption power even when the operation portion and the vibration reduction driving portion are operated simultaneously.
The camera includes at least one operation portion which operates based on electric power, an operation detection portion for detecting an operation of the at least one operation portion, a vibration reduction driving portion for reducing a vibration of the object image on the image taking surface by driving at least a portion of an image taking optical system, a vibration detection portion for detecting the vibration, a frequency restriction portion for, when the operation detection portion detects the operation of the operation portion, restricting the frequency range of the output signal from the vibration detection portion to a frequency equal to or lower than a predetermined frequency, and a control portion for controlling the vibration reduction driving portion on the basis of the output from the frequency restriction portion.
