【Task】 By irradiating ultraviolet light, violet visible light, and blue visible light, it is possible to distinguish the bone portion existing at or near the cut surface of meat when the meat block is cut into pieces. [Solution] In the dark An ultraviolet light photographing unit that irradiates the cut surface with ultraviolet light and takes in reflected light of the ultraviolet light to obtain an ultraviolet light image, A violet light imaging section that obtains a violet light image by irradiating the cut surface with violet light and incorporating reflected light of the violet light, When extracting the extraction target from the image data obtained by irradiating the cut surface with blue light and incorporating the reflected light of the blue light to obtain a blue light image, the bone part of the cut surface of the meat is extracted. An apparatus for discriminating bones of meat by the method of deep learning that discriminates between. [Selection diagram] Figure 1
