Abstract

Multiple flat-panel displays have been widely used as business and consumer electronic equipment. Although stereo or multiple display units are of the same brand and model, users often experience temporary visual fatigue due to the color differences between flat-panel displays. Therefore, color calibration between multiple display units displayed at the same time has been receiving attention from display manufacturers. In this paper, a camera-based color calibration method for multiple flat-panel displays that uses a portable smartphone camera is proposed. The color calibration algorithm used in the proposed method consists of three parts: geometric registration based on a chessboard detector, camera parameter optimization based on the distortion model of camera's optical system and environmental factors, and color matching for fast calibration. Experimental tests proved the practicality and the reliable calibration performance of the proposed color calibration method for the aftermarket.
