Maturity determination device and maturity determination method
A maturity determination device includes an image capturing device to capture a image including a plurality of first and second pixels; and a signal processing circuit configured to find an area size ratio of an intensity distribution of light of a first wavelength band on the basis of a predetermined reference value based on pixel values obtained from the plurality of first and second pixels, and to generate maturity determination information in accordance with the area size ratio. The first pixel includes a first light transmission filter, and the second pixel includes a second light transmission filter. The intensity of the light of the first wavelength band reflected by the fruits and vegetables varies in accordance with the maturity level, and the intensity of the light of the second wavelength band reflected by the fruits and vegetables is substantially the same regardless of the maturity level.
