摘要

A tablet inspection device according to the present embodiment has an acquisition unit for acquiring spectral images of a photographed tablet at a prescribed time interval; a two-dimensional image generation unit for generating a two-dimensional image by integrating the plurality of spectral images in the wavelength direction; an extraction unit for extracting a prescribed area of the tablet within the two-dimensional image as an extracted image; a normalization unit for calculating normalized spectrums by normalizing the intensity spectrums of each pixel in the extracted image; a second-order differential calculation unit for calculating, as a second-order differential spectrum, the second-order differential of the average of the normalization spectrums calculated for each of the pixels in a selected extracted image; and a determination unit for determining, on the basis of the second-order spectrum, whether a tablet corresponding to the selected extracted image is a tablet of a prescribed type.
