A method for characterizing a liquid crystal display (LCD) was developed using a characterized digital still camera (DSC). Prediction accuracy of the method was evaluated through calculating the Euclidean distance between prediction and the corresponding reference in the most lately standardized color appearance model CIECAM02 with rescaled lightness. This paper describes a framework for obtaining a device-independent representation of displayed colors on the monitor with a less time-consuming method for accurate characterization. A DSC was first characterized using a polynomial model and then an LCD was characterized using two instruments: a tele-spectroradiometer and the characterized DSC. In total, five characterization methods were tested of which PLCC predicted the results most accurately.
Key words: CIECAM02-UCS, LCD characterization, digital still camera, color difference
