Abstract

A document reading unit includes an R light source(211), a G light source(212), a B light source(213), a UV light source(214), a lighting control unit(241), a first photoelectric conversion element(216), a second photoelectric conversion element(218), a lens(219), and an output unit(243). The first photoelectric conversion element(216) includes an M filter. The second photoelectric conversion element(218) includes a G filter. The output unit(243) outputs outputs of the first photoelectric conversion element(216) and the second photoelectric conversion element(218) at the time of simultaneous lighting of the R and G light sources(211, 212) and an output of the first photoelectric conversion element(216) at the time of simultaneous lighting of the B and UV light sources(213, 214) as the image data, and outputs an output of the second photoelectric conversion element(218) at the time of simultaneous lighting of the B and UV light source(213, 214) as fluorescent color data indicating a fluorescent color region.
