摘要

Disclosed are an apparatus and a method of evaluating image quality for real-time iris recognition, and a storage medium having a program thereof which are capable of detecting only a suitable image in an iris recognition in real time in order to quickly and accurately identify an individual person. Sampling unit receives an image of an eye, divides image of an eye into pixel regions of predetermined units, and obtains an average of the pixel regions in order to sample the image of an eye. Absolute evaluation unit detects a pupil from the sampled image of an eye, absolutely evaluates image quality of pupil to obtain an absolute evaluated value, and eliminates an image having an absolute evaluated value less than an absolute reference value and outputs an image having an absolute evaluated value greater than absolute reference value. Relative evaluation unit restores a pupil of the sampled image to an original size, matches a pupil of region with the photographed image of an eye, and relatively determines a priority of the image quality.
