Abstract: One embodiment of the present invention provides a system that tests the motion performance of an electronic display system, wherein the electronic display system includes a display, graphics processing software, graphics processing circuitry, and an interface coupling the display and the graphics processing circuitry. The system starts by receiving a request to measure an amount of distortion of an object in motion. In response to the request, the system measures the amount of distortion of the object in motion. In a variation on this embodiment, measuring the amount of distortion of the object in motion involves placing a ruler on a boundary of the object where the distortion occurs, increasing the width of the ruler until it covers the distortion, and then measuring the width to determine the size of the distortion.

Abstract: A system and method for testing and evaluating a display device and its associated display drive circuitry through computer generated graphic test patterns which are dynamically alterable. The system comprises a display device for displaying the test patterns, a computer for generating the test patterns which typically are dynamically alterable and a communication line for coupling the computer and the display device together so that the computer can transmit information forming the test patterns to the display device. The test patterns are monitored visually to detect video artifacts. Alternatively, monitoring may be performed by measuring devices such as signal analyzing devices or optical testing devices.The method for evaluating and detecting video artifacts of a display device and its associated display drive circuitry is performed through at least three steps.
