<p>PURPOSE:To read an RGB component of a picture of a line and to improve the processing efficiency considerably without selection of filters with one line scanning by arranging a color filter in which each of red, green, blue colors are scattered in mosaic between a light source and a film original. CONSTITUTION:A film original 7 in this embodiment is inserted between a condenser lens 12 and an image forming lens 5 and a diffusion board 16 is provided to a front face so as to allow a transmission light from an RGB mosaic filter 15 to radiate to the film original 7 efficiently. The RGB mosaic filter 15 scatters each of R, G, B colors in mosaic, converts the spectral characteristic of a light source, that is, a halogen lamp 1 into the spectral characteristic in matching with the constitution of the optical system to adjust the RGB luminous quantity of the halogen lamp 1 depending on the RGB mosaic filter 15 optimizingly.</p> |
