Abstract
A rotation detection device according to one embodiment includes an angular velocity sensor attached to a rotating body that rotates and configured to detect an angular velocity of the rotating body, and at least one processor configured to perform a control based on the angular velocity detected by the angular velocity sensor, in which the at least one processor is configured to perform processing for calculating a first angle of the rotating body before a rotation operation is performed on the rotating body and a second angle of the rotating body after the rotation operation is performed on the rotating body based on the angular velocity sensor.
