摘要
The present invention relates to an eye searching method and an eye state detection apparatus and an eye searching apparatus using the same. The method comprises the steps of: defining each center point of two nostrils from a face image; computing a distance D between the two center points of the two nostrils and a midpoint between the two center points of the two nostrils; determining a reference point that has a horizontal distance k1×D and a vertical distance k2×D spaced apart from the midpoint, wherein k1=1.6˜1.8, k2=1.6˜1.8; and defining a rectangle around the reference point as its center, wherein the rectangle has a width and a length greater than the width, and the rectangle surrounds the eye of the face image. Accordingly, the present invention can quickly and accurately find out a certain part of the eye from the face image.
