Abstract

System and method for evaluating a dynamic color deviation of a moving image of LCD is disclosed. The system comprises a means for capturing image, which captures a moving image of a displayer to be evaluated using a tracking method with simulation of a human's eyes. After that, a means for regulating a magnification of the image, a means for positioning a monitor's margin, and a means for positioning the image are used. Next, a means for color characterization is used to correct a chroma of the image so as to process the evaluation in a homogenized color space. Furthermore, a visual model is incorporated to process the analysis of the luminosity, color deviation of the captured image. The above-mentioned means of the present invention transforms the captured image into a coordinate system of the color space so as to generate a quantified evaluation.
