Patent ID: 8126215

Claim:
A registration apparatus comprising: extraction means for extracting characteristics of a subject of biometric identification at every predetermined period as a binary image on the basis of video signals output from an image pickup element as a result of picking up characteristics images of the subject of biometric identification at sequentially differentiated image pickup positions in response to a relative movement of the image pickup element and the subject of biometric identification at a predetermined biological site wherein: the video signals output from the image pickup element may be comprised of multiple sources of biometric data; and the characteristics images of the subject of biometric identification show biological components that are the subject of biometric identification shot successively at different image pickup positions; first degree of similarity detection means for detecting a first degree of similarity between a binary image currently being processed and either a binary image processed immediately before the binary image currently being processed or a binary image to be processed which is located sequentially adjacent to the binary image currently being processed; and registration means for registering the binary image currently being processed as biometric identification information when: the first degree of similarity is not smaller than a first threshold value; a first positional displacement quantity between the binary image currently being processed and the binary image processed immediately before the binary image currently being processed is not smaller than a first displacement threshold value; the binary image currently being processed is aligned with temporarily registered binary images; a correlation value of the aligned binary images is not smaller than a second threshold value; and a second positional displacement quantity between a first binary image and the binary image currently being processed is not smaller than a second displacement threshold value.
