Abstract

In this monitoring method, automatic adjustment processing of a display device that displays a video is monitored. In the monitoring method, in a display system including a display device that displays a video, an imaging device that captures an image of the display state of the display device, and an adjustment device that adjusts the display state of the display device, the adjustment executed by the adjustment device is monitored in accordance with a predetermined monitoring schedule. The adjustment device includes an arithmetic circuit capable of accessing a storage device that stores adjustment history data including a history of one or more parameter values indicating the display states of the display device obtained from images captured by the imaging device in past adjustments. In the monitoring method, the success or failure of the adjustment is determined by the arithmetic circuit according to the display state of the display device, the image of which has been captured by the imaging device, if the adjustment is determined to be unauthorized, a history of past adjustments is extracted from the adjustment history data in the storage device, and the display device is adjusted using the extracted history of adjustments.
