Abstract
A method for smoothing coordinates, a touch chip, and an electronic terminal are provided. The method includes: acquiring touch point coordinates of a current data frame on a touch screen, and touch point coordinates of N consecutive data frames prior to the current data frame, the N is a natural number greater than or equal to 2; performing a Bessel interpolation iteration on the touch point coordinates of N+1 data frames including the current data frame with the touch point coordinates of the N+1 data frames as initial iteration values; and acquiring an iteration result of the Bessel interpolation iteration, and implementing coordinate smoothing according to the iteration result. According to the embodiments of the present disclosure, the cost of smoothing coordinates is lowered, and the effect of smoothing coordinates is improved.
