摘要

According to the embodiment, the tablet inspection device acquires an acquired spectrum image of a tablet at predetermined time intervals, and generates a two-dimensional image that generates a two-dimensional image obtained by integrating a plurality of spectrum images in the wavelength direction. An extraction unit that extracts a predetermined region of the tablet in the two-dimensional image as an extraction image, a normalization unit that calculates a normalized spectrum obtained by normalizing the intensity spectrum of each pixel in the extraction image, and the selected extraction image A secondary differential calculation unit that calculates a secondary differential spectrum as an average secondary derivative of the normalized spectrum calculated for each pixel, and a tablet corresponding to the selected extracted image is determined based on the secondary differential spectrum. A determination unit that determines whether the tablet is of a type.
