Patent ID: 7885439

Claim:
An information creation apparatus for creating information on a body, comprising: a solid imaging element configured to sequentially capture a plurality of blood vessel images of a same image type based on near-infrared light received from the body; a binarization unit configured to create a plurality of binarized images from the plurality of blood vessel images sequentially received from the solid imaging element; a composition unit configured to sequentially perform an averaging process on the plurality of binarized images to create a composed binarized image; an elimination unit configured to eliminate isolated pixels from the composed binarized image received from the composition unit; and a creation unit configured to create identification information based on the blood vessels of the composed binarized image subjected to the elimination of the elimination unit, wherein the elimination unit is configured to eliminate a prescribed number or fewer isolated pixels, to determine whether a number of the isolated pixels eliminated is a prescribed threshold value or lower, and when the number of the isolated pixels eliminated is determined to be the prescribed threshold value or lower, to identify the composed binarized image subjected to the elimination as being usable for creating the information on the body; and the creation unit is configured to create the identification information based on the blood vessels of the composed binarized image identified by the elimination unit.
