ABSTRACT:
In a display device having a nonvolatile memory device, such as an active matrix type liquid crystal display device, display contents displayed on the display device are obtained by a camera device. The obtained information (corresponding to the display contents) is digital-converted and then processed to detect a defect and a nonuniformity on the display device, so that correction information is produced. The correction information is stored in the nonvolatile memory device of the display device. Display information to be displayed on the display device is processed using the stored correction information, so that display contents are corrected and a defect and a nonuniformity on the display contents are inconspicuous.
