  • Publication number: 20250117982
    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.

  • Patent number: 9227748
    Abstract: A metal bottle can comprises a mouth part having a curl portion at the end, a neck part having a straight part in parallel to the can axis, a taper-shaped shoulder part, a barrel part, and a bottom part. The metal bottle can is integrally formed from a primitive plate of the thickness (wall thickness T) of 0.48 mm to 0.30 mm by drawing-processed. The metal bottle can has the barrel part with the diameter A of 40 mm to 70 mm, the neck part with the diameter B of 20 mm to 35 mm, the straight portion of the neck part with the length S of 10 mm to 40 mm, the shoulder part with the angle ? of 40 degrees to 70 degrees, the mouth part with the wall thickness X of 0.46 mm to 0.33 mm, and straight portion of the neck part with the wall thickness Y of 0.43 mm to 0.30 mm.
