Summary:A biometric instrument comprises an illuminating unit for illuminating an organism, i.e., a subject, an imaging unit for photoelectrically converting the light of the illuminating light reflected from the organism and generating an imaging signal, and a signal processing control unit for controlling the operation of the imaging section and outputting the imaging signal to a display. The biometric instrument is characterized in that the signal processing control unit includes a spectral signal generating section for generating a spectral signal corresponding to an image in an optical wavelength narrow band from the imaging signal by signal processing, a color adjusting section for assigning color tones different with the bands where the spectral signal is formed when the spectral signal is outputted to the display, and an image quality adjusting section for adjusting the image quality of the signal outputted to the display, or the other signal processing sections than at least the spectral signal generating section and the color tone adjusting section are shared for the signal processings of the imaging signal and the spectral signal.
