Abstract: A display calibration system includes: a display device; an capture device that captures the image displayed on the display device; and a server connected to the capture device through a communication path. The server acquires the image captured by the capture device through the communication path, generates correction data used to correct the display characteristic of the display device by performing arithmetic operation of the acquired image, and transmits the generated correction data to the display device or a control device connected to the display device through the communication path.
