1. A biometrics authentication device, which verifies registered biometrics characteristic data for a user against biometrics characteristic data detected from a body to perform individual authentication, comprising: an image capture unit, which captures an image of the body; a storage unit, which stores said biometrics characteristic data and body image capture state data for the user; a display unit, which displays guidance screens to the user for use in image capture of the body; and a processing unit, which extracts the body image capture state data and biometrics characteristic data from the images of the body captured by the image capture unit and registers the extracted body image capture state data and biometrics characteristic data in the storage unit, wherein the processing unit extracts the body image capture state data from images of the body captured by the image capture unit, compares the extracted body image capture state data with the body image capture state data registered for the user, displays a guidance screen on the display unit according to the comparison result, and verifies the biometrics characteristic data registered for the user against the biometrics characteristic data detected from the body.
