ELECTRONIC DEVICE AND METHOD FOR DETERMINING METRIC OF SHARPNESS, RECORDING MEDIUM FOR PERFORMING THE METHOD

摘要

The present invention relates to an electronic apparatus and method for determining a criterion of sharpness, and to a recording medium for performing the method. The electronic apparatus for determining a criterion of sharpness comprises: a Bessel function determination unit which determines Bessel functions for a plurality of light emitting sources inside a display device; a light emitting source distance determination unit which determines distances between the light emitting sources when a shape of a distribution of the Bessel functions is identical to a preset edge shape; a blurriness value determination unit which determines a numerical value indicative of blurriness of an image, displayed on the display device, based on the distances between the light emitting sources; and a sharpness criterion determination unit which determines a criterion of sharpness for the display device based on the numerical value indicative of the blurriness.
