Abstract: An image capture device and anti-shake control method thereof are provided. The image capture device includes a command input unit, a lens unit, a vibration compensation unit, and a control unit. The anti-shake control method is performed by using the control unit to compare the zoom ratio of the lens unit with a predetermined value. When the zoom ratio is greater than or equals the predetermined value, the vibration compensation unit is enabled. When the zoom ratio is less than the predetermined value, the vibration compensation unit is disabled unless a first motion acts on the command input unit.
