发明名称 Method and system for synchronizing colorimetric rendering of a juxtaposition of display surfaces uniform
摘要 A method for making uniform the colorimetric rendering of a display surface including several adjacent display screens (10a, 10b), comprising for each pair of adjacent screens (10a, 10b) steps of: periodically sampling (21) by a calculation device (5) image data in two corresponding screen (10a, 10b) areas (13a, 13b) in the pair of adjacent screens, analyzing (22, 23, 24) by the calculation device (5) image data sampled in each period to determine a difference in calorimetric rendering between the two screen areas, determining by a correction device (6) connected to the calculation device a process to be applied to the video stream to one of the two video systems controlling the two screens in the pair of adjacent screens, by applying a predetermined correction law to the difference in calorimetric rendering, and applying (26) by the correction device the process to said video system, in order to make the colorimetric rendering of the display surface uniform.
