1. A virtual mouse driving apparatus, comprising
an image capturing apparatus arranged for capturing a plurality of input images continuously; an image processing unit arranged for detecting a finger area from the plurality of input images; an event recognition unit arranged for detecting a specific event of the finger area; and a command processing unit arranged for generating a corresponding virtual mouse control command according to the specific event, wherein the image processing unit detects a skin area from the plurality of input images, and generates a skin edge area according to the skin area, and the image processing unit further calculates an included angle between each pixel of the skin edge area and two terminal points extended by a predetermined distance from both sides thereof, calculates a corresponding cosine value of the included angle, and generates the finger area according to the corresponding cosine value.
