发明名称 DISPLAY IMAGE CORRECTING DEVICE, IMAGE DISPLAY DEVICE, AND DISPLAY IMAGE CORRECTION METHOD
摘要 <P>PROBLEM TO BE SOLVED: To correct brightness unevenness of a display device more efficiently. <P>SOLUTION: The display image correcting device forms a reference correction amount table, on the basis of a set of reference two-dimensional correction amount data obtained at a correction point, corresponding to the horizontal direction and the vertical direction of an image. This reference correction amount table is defined as only one made to correspond to one specific level of luminance, without preparing two or more tables made to correspond to two or more levels of luminance. In actual correction, three-dimensional correction amount data are obtained, by making the reference two-dimensional correction amount data read out of the specific luminance proportional linearly or non-linearly to the luminance level of the video signal to be corrected. Then, the video signal is corrected by using these three-dimensional correction amount data. <P>COPYRIGHT: (C)2007,JPO&INPIT
