Abstract
Abstract An individuality discriminating system wherein analog signals of a human individual picture are converted to digital signals according to brightness of the picture, and such digital signals are stored as individual picture data in an integrated-circuit (IC) card as compressed, with picture elements other than changed ones in the picture treated as zero picture elements, while in using the IC card by its bearer the thus stored data are read out of the card as expanded and analog-converted for display on a monitor. Since the picture data are compressed to remarkably reduce code volume upon the storing in the card, the individuality discrimination can be realized practically precisely and effectively reliably through an investigators's comparison with eyes of the thus displayed picture with a directly viewed or monitored picture of the bearer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
An individuality discriminating system comprising means for monitoring an individual, means connected to said monitoring means for digitizing an analog picture from the monitoring means into digital picture data in accordance with brightness of said analog picture and compressing, for further processing, picture elements of said digital picture data which are changed from predetermined picture elements, any other picture elements which show no such change being compressed as zero picture elements, means for writing said compressed picture data on a card to be used by said individual, means for reading said picture data off of said card through expansion and analog conversion of the compressed data, and means connected to said reading means for displaying said data.
Claim 2
Dependent Claim
117 words
An individuality discriminating system comprising means for monitoring an individual, means connected to said monitoring means for digitizing an analog picture from the monitoring means into digital picture data in accordance with brightness of said analog picture and compressing, for further processing, picture elements of said digital picture data which are changed from predetermined picture elements, any other picture elements which show no such change being compressed as zero picture elements, means for writing said compressed picture data on a card to be used by said individual, means for reading said picture data off of said card through expansion and analog conversion of the compressed data, and means connected to said reading means for displaying said data.
Claim 3
Dependent Claim
35 words
A system according to claim 1, wherein said changed picture elements are of a human figure of the individual in said picture data and said other picture elements are of a background in the data.
Claim 4
Dependent Claim
128 words
An individuality discriminating system comprising means for monitoring an individual, means connected to said monitoring means for digitizing an analog picture from the monitoring means into digital picture data in accordance with associated brightness of said analog picture and compressing picture elements of said digital picture data which are changed from predetermined picture elements, any other picture elements which shown no such change being compressed as zero picture elements, means for writing said compressed picture data on a card to be used by said individual, means for reading said picture data off of said card through expansion and analog conversion of the compressed data, and means for displaying said expanded analog picture, said digitizing and compressing means clips a face picture of the individual from said picture data.
Claim 5
Dependent Claim
128 words
An individuality discriminating system comprising means for monitoring an individual, means connected to said monitoring means for digitizing an analog picture from the monitoring means into digital picture data in accordance with associated brightness of said analog picture and compressing picture elements of said digital picture data which are changed from predetermined picture elements, any other picture elements which shown no such change being compressed as zero picture elements, means for writing said compressed picture data on a card to be used by said individual, means for reading said picture data off of said card through expansion and analog conversion of the compressed data, and means for displaying said expanded analog picture, said digitizing and compressing means clips a face picture of the individual from said picture data.
Claim 6
Dependent Claim
35 words
A system according to claim 3, wherein said digitizing and compressing means further clips part of said face picture and compresses said clipped face part at a compression rate higher than that of other parts.
