PROBLEM TO BE SOLVED: To provide a sensor IC capable of reading light outside the visible range.SOLUTION: A sensor IC 301 according to the present invention includes: first to fourth light-receiving portion rows 321 to 324 having a plurality of first to fourth light-receiving portions arranged along a main scanning direction; and a control circuit 35 connected to the first to fourth light-receiving portions. The first to fourth light-receiving portion rows 321 to 324 are arranged along a sub-scanning direction. Each first light-receiving portion receives blue light, each second light-receiving portion receives green light, and each third light-receiving portion receives red light. Each fourth light-receiving portion receives infrared light and ultraviolet light outside the visible range. The control circuit 35 outputs a first electrical signal S1 according to light received by each first light-receiving portion, outputs a second electrical signal S2 according to light received by each second light-receiving portion, outputs a third electrical signal S3 according to light received by each third light-receiving portion, and outputs a fourth electrical signal S4 according to light received by each fourth light-receiving portion. |
