Title:
検査装置、ＰＴＰ包装機、及び、検査装置の較正方法
Document Type and Number:
Japanese Patent JP6568245
Kind Code:
B2
Abstract:
There are provided an inspection device configured to improve the inspection accuracy in an inspection that is performed by taking advantage of spectral analysis, as well as a PTP packaging machine and a calibration method of the inspection device. An inspection device 22 comprises an illumination device 52 configured to irradiate tablets 5 with near-infrared light; and an imaging device 53 configured to disperse reflected light of the near-infrared light that is reflected from the tablets 5 and take an image of the reflected light. The inspection device 22 is configured to perform an analysis process, based on spectroscopic image data obtained by the imaging device 53. The inspection device 22 performs a predetermined arithmetic operation of standard spectroscopic image data obtained in advance by taking an image of an optical spectrum with regard to a predetermined standard plate, so as to determine a characteristic of each pixel row and thereby grasp a wavelength sensitivity characteristic of an imaging element. The inspection device 22 subsequently calculates a correction value with regard to each pixel of standard spectroscopic image data. In the process of an inspection, the inspection device 22 corrects a luminance value of each pixel of inspection spectroscopic image data obtained by taking an image of an inspection object, based on the correction value with regard to the pixel.
