A method and an apparatus for detecting a touch point movement are provided. In the present method, a touch panel is detected to obtain the positions of m previous touch points Pi during a frame period and the positions of n current touch points Pj′ during another frame period. Distances D(i,j) between the previous touch points Pi and the current touch points Pj′ are calculated, and a minimum distance among valid ones of the distances D(i,j) is found out. If a distance D(a,b) among the distances D(i,j) is the minimum distance, the current touch point Pb′ is defined as a touch point moved from the previous touch point Pa, and the distances D(a,1)-D(a,n) and the distances D(1,b)-D(m,b) are defined as invalid values. |
