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.

Abstract: A stereoscopic shooting device includes: a first and second shooting sections that obtain a first and second images, respectively; and an angle of view matching section. The angle of view matching section performs: calculating a vertical image area of the second image that has the same vertical direction range as the first image by comparing ratios of the vertical coordinates of respective representative points in image blocks selected from the first and second images, respectively; adjusting the number of horizontal lines included in the vertical image area of the second image and the number of horizontal lines included in the first image; outputting a first and second horizontal line signals representing the horizontal lines included in the first image and the vertical image area of the second image, respectively; and carrying out stereo matching by comparing the first and second horizontal line signals to each other.
