A control method is provided, including: obtaining input information, where the input information includes a capacitance signal and report point coordinates generated when a user performs an operation on a terminal screen; using report point coordinates in a previous frame as report point coordinates in a current frame if it is determined that a capacitance signal in the current frame and a capacitance signal in the previous frame that are in the input information meet a preset condition; or using report point coordinates in a previous frame as report point coordinates in a current frame if it is determined that the report point coordinates in the current frame and report point coordinates in a first frame that are in the input information meet a preset condition.
