A blocking mechanism of a privacy protection shutter for a camera is provided on an outer edge portion of a display of an electronic device. The privacy protection shutter includes a rotation pivot with which the privacy protection shutter is rotatable; a blocking portion that covers a lens of the camera to disable the camera to image at a block position; and an operation portion configured to cause the privacy protection shutter to rotate with the rotation pivot so as to move the blocking portion between the block position and an open position at which the lens is not covered by the blocking portion.
