Provided are a drug detection device and a drug detection method that are able to compute the residual amount of a drug quickly and in a contactless manner. The drug detection device according to the present invention is for detecting a drug remaining in a target area, and includes an irradiation unit configured to irradiate a target area with a light beam including near-infrared light, a spectroscope on which reflected light from the target area is incident, a near-infrared imaging unit configured to capture a spectrum obtained through dispersion of the reflected light by the spectroscope and to generate image data, a control unit configured to process the image data, and a storage unit configured to store an equation expressing a relationship between a prescribed amount of a drug and spectral data that is based on the spectrum. The near-infrared imaging unit is configured to capture each spectrum of a predetermined number of pixels allocated within the target area, and the control unit is configured to compute average spectral data of the area by averaging the spectrums of the pixels, and to compute an amount of the drug corresponding to the average spectral data, based on the equation stored in the storage unit. |
