Abstract: An image processing method includes: obtaining a first RGB image generated by capturing an image of a tooth and dental plaque that are fluorescing in response to exposure to light including a blue-light wavelength range; and generating a second RGB image by performing, for the first RGB image, image processing including first image processing. In the first image processing, the gains of at least two color components among the red component, the green component, and the blue component of an RGB image to be processed are adjusted so as to equalize the first red pixel average value of red pixel values, the first green pixel average value of green pixel values, and the first blue pixel average value of blue pixel values, the red pixel values, the green pixel values, and the blue pixel values being the pixel values of first pixels corresponding to the tooth.
