PROBLEM TO BE SOLVED: To pick up images of the subject and a colorimetric reference chart stably.SOLUTION: An image pickup unit 30 includes, at a bottom 32a opposed to the subject, an opening 32c for picking up an image of the subject and a reference chart KC fitted in a concavity 32d formed on the outside of the opening 32b and supported by a holding member 32e, and has an image sensor unit 34 disposed at center inside of a frame 32 of a board 31. The image sensor unit 34 has disposed therein a two-dimensional image sensor 35 which picks up images of the subject and the reference chart KC upon receiving reflected light therefrom and image formation lenses 36b, 36c which condense the reflected light incident upon the two-dimensional image sensor 35, as well as a douser 36a. The image formation lenses 36b and 36c each have a curvature corresponding to the lengths of their respective optical paths. |
