<p>PROBLEM TO BE SOLVED: To improve the accuracy of reading an image at a position irradiated with overlapping rays of light from a plurality of LED light sources.SOLUTION: An image reading device 50 includes a plurality of white LED light sources 40 that are arranged to have ends to be overlapped in the width direction of a recording sheet P, a CCD sensor 70 that detects color information on the recording sheet P and a white plate 72 as an RGB value from reflected light of the light from the white LED light sources 40 for each pixel, and a control device 60 that performs shading correction to the color information on the white plate 72, and then performs color material color shading correction of color information on overlapped pixels corresponding to a position irradiated with overlapping rays of light from the white LED light sources 40 to the color information on each solid image painted out with each color material.</p> |
