US 2003/0080985 A1 · Method of adjusting image, and image display system, image display device and image data generation device

Abstract

When a user instructs an image display device (1b) to perform an automatic level adjustment, the image display device (1b) transmits the instruction to an image data generation device (2b). Then, the image data generation device (2b) sends adjusting-image data generated by an adjusting-image data generator (11) to the image display device (1b). When the adjusting-image data is completely sent out, the image data generation device (2b) notifies the image display device (1b) of completion of data sending. When the image display device (1b) is notified that the adjusting-image data is completely sent out, an automatic level adjuster (6b) performs the automatic level adjustment. At this time, the automatic level adjustment is performed on the basis of the adjusting-image data. Thus, an image display system consisting of the image data generation device and the image display device achieves an easy automatic image adjustment using image data suitable for the image adjustment.
