Zusammenfassung: | The present invention relates to an LED electronic display board system having a function of automatically calibrating image quality of the LED electronic display board changing according to an external environment and a method thereof and, more specifically, to an LED electronic display board system having a function of automatically calibrating image quality of the LED electronic display board changing according to an external environment and a method thereof, allowing a controller to calibrate a value of a corresponding color outputted by the LED electronic display board based on an adjusted color value by dividing, into multiple areas for respective colors, a photographed calibrated image resulting from photographing an image into which a calibration image for calibrating a color outputted by the LED electronic display board is inserted due to a change in the external environment and comparing a color value for a divided area with a color value encoded in an identification image included in the photographed calibrated image to extract the adjusted color value of the corresponding color.
본 발명은 외부 환경에 따라 변화하는 LED전광판의 화질을 자동적으로 보정하는 기능을 갖는 LED전광판 시스템 및 방법에 관한 것으로서, 더욱 상세하게는 외부 환경의 변화로 인해 LED전광판에 출력되는 색상을 보정하기 위한 보정이미지가 삽입된 영상을 촬영한 촬영보정이미지를 색상별 복수의 영역으로 분할하고, 분할된 영역에 대한 색상값과 촬영보정이미지에 포함된 식별이미지에 인코딩된 색상값을 비교하여 해당 색상의 조정색상값을 도출하여, 컨트롤러에서 상기 조정색상값에 기초하여 LED전광판에서 출력하는 해당 색상의 색상값을 보정하는, 외부 환경에 따라 변화하는 LED전광판의 화질을 자동적으로 보정하는 기능을 갖는 LED전광판 시스템 및 방법에 관한 것이다. |
