Abstract: A report point output control method and apparatus includes performing feature detection on a capacitance hot spot to determine an eigenvalue of the capacitance hot spot, determining, based on the eigenvalue of the capacitance hot spot, whether a report point matching the capacitance hot spot is from an odd-form touch, and skipping outputting the report point when the report point is the report point generated by the odd-form touch. The eigenvalue includes at least one of a horizontal span, a longitudinal span, an eccentricity, a barycenter coordinate, a maximum capacitance value, an average shadow length, an upper left shadow area, or a lower right shadow area.

Abstract: 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.
