Abstract
An apparatus and a method for controlling a rotating body in an electronic device are provided. The method includes emitting light to at least one indicator among a plurality of indicators having different reflectivities in a rotating body, receiving light reflected from the at least one indicator, detecting a rotation parameter of the rotating body based on an amount of the reflected light received from the at least one indicator, and controlling the rotating body based on the rotation parameter.
