Image reading device and semiconductor device configured to image or read fluorescent colors

An image reading device for reading an image including a fluorescent color, the image reading device comprising:

• a first light source having a maximum light emission intensity at a first wavelength that is 400 nm or greater and 500 nm or less;
• a second light source having a maximum light emission intensity at a second wavelength that is longer than the first wavelength;
• and
• an image reading chip configured to read the image, the image reading chip having a pixel including a photodetector that performs photoelectric conversion on light received from the image, wherein:
• the spectral sensitivity of the photodetector when photoelectric conversion is performed takes a maximum value at a wavelength on a short wavelength side relative to the first wavelength, the short wavelength side being within a region from 400 nm to 500 nm inclusive.
