1. A method for detecting blepharoptosis, comprising:
image capturing via a camera to generate three eye images including a pupil image gazing forward, a pupil image gazing upward to the maximum extent, and a pupil image gazing downward to the maximum extent, respectively;
executing an image processing on the eye images to generate the corresponding border images;
executing an image computing on the eye images and the corresponding border images to obtain a plurality of characteristic variables including position coordinates of an eye profile region, a sclera region, an iris region, a pupil region, a pupil center point, an upper eyelid inferior margin curve, a lower eyelid superior margin curve, a center point of the upper eyelid inferior margin curve and a center point of the lower eyelid superior margin curve, respectively;
performing a calculation according to the plurality of characteristic variables to obtain a characteristic parameter set; and
comparing the characteristic parameter set with a preset blepharoptosis criteria information to obtain a blepharoptosis severity and a levator function.
