1. A method of measuring light emission characteristics of a display panel, comprising: setting a location of a camera such that a imaging range area of the camera includes a first divided region among a plurality of divided regions, wherein the display panel is larger than the imaging range area of the camera and includes the divided regions, and wherein each of the divided regions is smaller than the imaging range area; first displaying a recognition pattern image on the first divided region; first shooting the first divided region by the camera so as to generate a recognition pattern shot; second displaying a single-color image on the first divided region; second shooting the first divided region by the camera so as to generate a single-color shot; modifying the single-color shot based on the recognition pattern shot so as to generate a modified single-color shot corresponding to the first divided region; repeatedly performing the setting, the first displaying, the first shooting, the second displaying, the second shooting, and the modifying until all of the modified single-color shots corresponding to the divided regions are generated; and combining all of the modified single-color shots so as to generate a whole single-color shot of the display panel.
