<p>PURPOSE:To obtain a multicolor filter matching with characteristic proper to individual image tube by making incident light with two or more kinds of colors separately via a filter, and manufacturing a multicolor filter for light output based on the position information of an image appearing on an output plane. CONSTITUTION:A multicolor filter 2 for light input in which two or more kinds of fine input areas transmitting the light with two or more kinds of colors are dispersed uniformly is set on the input plane 11 of the image tube 1. Next, the light with two or more kinds of colors are made incident on the image tube 1 separately via the multicolor filter 2 for light input, and the position information of the image of microinput appearing on the output plane 12 is fetched at every incidence of light with two or more kinds of colors, then, the multicolor filter for light output in which microoutput areas are dispersed corresponding to the microinput areas is manufactured based on the position information. Thereby, the distortion and shading of the image tube 1 can be fetched optically at a state where the multicolor filter 2 is set on the input plane, accordingly, the multicolor filter stuck on the output plane can be manufactured, therefore, the multicolor filter matching with the characteristic proper to individual image tube 1 can be obtained.</p> |
