    • An inspection apparatus which automatically inspects a bottom border portion of a transparent glass vessel for a foreign article accurately is disclosed. Light is projected and received by way of first and second polarization filters (15, 18) through a rotating glass vessel (1) to image the vessel (1) obliquely from below by a camera (16) including a plurality of solid state image pickup elements. Brightness values of outputs of the elements of the camera (16) are compared with respective threshold values and are determined as abnormality values when they are higher. The threshold values are varied and the abnormality values are corrected in accordance with the positions of the elements of the camera (16), and then presence or absence of a foreign article is determined from the corrected abnormality values or the sum of them.

    • PROBLEM TO BE SOLVED: To provide a method of specifying a defect accompanied in a wall of a bottle with spots.
      SOLUTION: Disclosed is a glass bottle checking machine for checking the defect of the glass bottle 10 with the spots. The glass bottle with the spots is supported by a checking station and is irradiated with a light source 14. The glass bottle with the spots is image-focused on a matrix of pixels, intensity of the each pixel in an image is changed from a bright state to a gray state in a position of the each spot. A computer evaluates the pixel of the image containing a look-up table for values allocated to specified light intensities from the bright state to a black condition. A plot of the look-up table has a high-gain portion 30 from black color to gray color, and a continuous low-gain portion 32 from the gray color to white color.
