Abstract: A detection device and a rotation detecting method for the crown of a smart watch are provided. Operations on the crown include a pressing action and a rotation action. The method includes: detecting the rotation angle of the crown within a set period of time when the pressing action is identified to obtain a measured rotation angle; and eliminating a misrotation angle from the measured rotation angle, to obtain a true rotation angle corresponding to the rotation action, and taking the true rotation angle as a detection result.
