摘要： A method and apparatus for evaluating the degradation of a video display device. Single parameter test signals and patterns, generated either internally or externally to the video device, are displayed on the screen. A sensing device such as a CCD camera reads the screen and transmits the data to a processing unit. Codes, imbedded in the test signal or pattern, indicate to the testing device what test is currently being run, the content of the test, and/or the specific setup situation. The code may be inherent in the pattern, the sequencing, or in addition thereto. The processing unit reads and interprets the results in accordance with the received test codes. The apparatus includes a portable, hand-held unit capable of detecting video degradation on a pass/fail basis. The unit is separate from the display under test and is capable of identifying and evaluating the test through the receipt and interpretation of the embedded codes in the test patterns, and evaluating performance on a go/no-go basis.
