IMAGE WARPING CORRECTION DEVICE BASED ON 3D VIRTUAL SCREEN

摘要

PURPOSE: An image warping correction device based on a 3D virtual screen is provided to secure a high quality image by correcting image warping without using a convergence yoke. CONSTITUTION: A reference image generating unit(62) generates a reference image for correcting image warping. A displacement measurer(61) measures RGB coordinates of pixels from the reference image. A warping information extracting unit(63) receives the measured RGB coordinate values and RGB coordinate values of an original image, and extracts warping information on the basis of a 3D virtual screen method. A warping correcting unit(56) generates a warping image using extracted warping information, and corrects the warping of the original image.
