<P>PROBLEM TO BE SOLVED: To provide an EL color display correcting device which performs temporal deterioration correction wherein influences of variance in temporal deterioration quantity among EL color display solid bodies and use conditions such as ambient temperature are taken into consideration. <P>SOLUTION: This EL color display correcting device has a color correcting means which inputs a video signal, makes color corrections according to color correction parameters, and outputs the corrected video signal, a color EL panel which inputs the corrected video signal and makes subpixels of R, G, and B illuminate to make a color display, a luminance sensor which measures the luminance of the display image on the color EL panel and outputs a luminance measurement value, a deterioration information generating means which previously stores deterioration characteristics of subpixels of R, G, and B of the color EL panel, derives deterioration information showing how much the subpixels of R, G, and B of the color EL panel from the luminance measurement value and deterioration characteristics, and outputs the information, and a color correction parameter calculating means which calculates the color correction parameters from the deterioration information and outputs them. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
