Abstract
Abstract When verification is performed using a plurality of fingers in accordance with a positional relationship of the joints of the fingers, an image of the plurality of fingers is separated into the images of the respective fingers, and comparison and collation are individually performed for the fingers. Phase data of each finger can be individually extracted, and a collation result of the fingers and phase shift data between the fingers based on phase data are generally determined. A guide member for guiding the placement of the fingers is mounted on a finger table to define positions at which the plurality of fingers are placed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
194 words
A personal verification apparatus for performing personal verification using a plurality of fingers, comprising: input means (11, 12, 13, 14) for inputting image data of the plurality of fingers; generating means (15, 16) for adding a density of the image data of the fingers input by said input means in a direction perpendicular to a longitudinal direction of the fingers to generate feature data; means for storing feature data to be collated; and collating means (15, 16, 19) for collating the feature data generated by said generating means with the feature data to be collated, characterized in that separating means (15, 22) for separating the image data of the plurality of fingers using data obtained by adding a density of the image data of the plurality of fingers input by said input means in the longitudinal direction of the fingers is provided; said generating means generates the feature data with respect to the image data of the fingers separated by said separating means; and said collating means collates the feature data generated by said generating means with the feature data to be collated stored in said memory means in units of the corresponding fingers.
Claim 2
Dependent Claim
194 words
A personal verification apparatus for performing personal verification using a plurality of fingers, comprising: input means (11, 12, 13, 14) for inputting image data of the plurality of fingers; generating means (15, 16) for adding a density of the image data of the fingers input by said input means in a direction perpendicular to a longitudinal direction of the fingers to generate feature data; means for storing feature data to be collated; and collating means (15, 16, 19) for collating the feature data generated by said generating means with the feature data to be collated, characterized in that separating means (15, 22) for separating the image data of the plurality of fingers using data obtained by adding a density of the image data of the plurality of fingers input by said input means in the longitudinal direction of the fingers is provided; said generating means generates the feature data with respect to the image data of the fingers separated by said separating means; and said collating means collates the feature data generated by said generating means with the feature data to be collated stored in said memory means in units of the corresponding fingers.
Claim 3
Dependent Claim
96 words
An apparatus according to claim 1, characterized by further comprising phase shift detecting means (15, 22, Fig. 7) for computing a phase coincidence position of the feature data and the feature data to be collated for the respective fingers in accordance with a collation result obtained by said collating means to detect a phase shift between these data on the basis of the phase coincidence position, thus determining personal verification in accordance with the collation result of the fingers obtained by said collating means and the phase shift data detected by said phase shift detecting means.
Claim 4
Dependent Claim
39 words
An apparatus according to claim 1 or 2, characterized in that said input means includes a finger table (11) on which the plurality of fingers are placed and a guide member (30) for guiding the placement of the fingers.
Claim 5
Independent Claim
32 words
An apparatus according to any one of claims 1 to 3, characterized in that the number and kind of the plurality of fingers are known to only a person to be verified.
Claim 6
Independent Claim
52 words
An apparatus according to any one of claims 1 to 4, characterized in that said separating means separates the image data corresponding to the plurality of fingers at a minimum value position of a sum signal obtained by adding a density of the image data in the longitudinal direction of the fingers.
Claim 7
Dependent Claim
40 words
An apparatus according to claim 3, characterized in that said guide member comprises a partition plate, and said apparatus further comprises means (21) for causing a position of said partition plate to correspond to a position on an input image.
Claim 8
Dependent Claim
27 words
An apparatus according to claim 1, characterized in that said generating means generates the feature data with respect to the image data of each of the fingers.
