  • Patent number: 9870611
    Abstract: Embodiments of the present invention provide a high accuracy medicament inspection device and system to inspect medicaments enclosed in a package with a printing area. The medicament inspection device implements a medicament information detection process that includes: a medicament candidate area extraction step extracting a dark colored area in a back side illuminated image as a medicament candidate area A (assumed presence of medicament); a print candidate area extraction step extracting an area containing the print on the package based on a front side illuminated image as a print candidate area B; a print area identification step specifying an area corresponding to the print contained in the print candidate area B based on the brightness distribution of the back side illuminated image as a print area C; and a medicament area identification step identifying a medicament area X by subtracting the print area C from the medicament candidate area A.
