摘要
Image data Rin, Gin, Bin are read out from an image on a document, on reception of light reflected by the image after being emitted from a first light source for irradiating the document with visible light. Image data RUV, GUV, BUV are read out from the image on the document, on reception of light reflected by the image after being emitted from a second light source for irradiating the document with ultraviolet light. A color correction process is performed by reading out color corrected imaged data from a color correction table which stores in advance color corrected image data, which are associated with a combination of (i) image data, which correspond to the image data Rin, Gin, Bin, and image data which correspond to the image data RUV, GUV, BUV. By this, it is possible that even in a case where an image on the document contains a fluorescent image, the fluorescent image be easily and accurately reproduced.
