Abstract

A measuring device for measuring a glow center of a display device is provided with: an image pickup device which includes a sensing surface defined by a plurality of photoelectric conversion elements arranged in a two-dimensional manner at a specified pitch and picks up a light image to produce image data, an optical system which transmits a light image displayed on a display device to the sensing surface of the image pickup device; an optical system controller which controls the optical system to transmit the light image to the sensing surface in such a manner that the maximum spatial frequency of the light image at the sensing surface of the image pickup device is smaller than the reciprocal of the pitch of the photoelectric conversion element arrangement; and a calculator which calculates a glow center of the light image on the display device based on image data produced by the image pickup device.
