Abstract
Abstract A process for creating a facial identification data base using a digital data processing computer system is provided. Entire photographic images of persons are first displayed and picked up by charge coupled solid state image sensors in a camera to produce electrical signals corresponding to the facial images. The sensors are horizontally and vertically disposed within the camera. The electrical signals are serially applied from the sensors to the computer system, where they are digitized and displayed onto the graphics monitor screen. Specific parameters relating to portions of the partial images to be stored are then inserted into the computer. The parameter data is then used to produce partial digitized images representing specific areas of said entire facial images, such as the forehead, nose, mouth or chin. The partial digitized images are produced by masking other areas of the total digitized image. The partial digitized images are then applied to a storage device such as a hard disk to provide the data base. The stored partial digitized images may then be selectively applied to a visual display means such as a television screen. Different partial images are selectively combined with other partial images to cause different total facial images to be selectively displayed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
169 words
A process for creating a facial identification data base using a digital data processing system by digitizing and storing partial photographic images of the faces of real people comprising the steps of: a. displaying an entire photographic facial image of a person; b. providing a camera having sensors therein to receive said entire facial image to generate electrical signals corresponding to said facial image; c. visually displaying said entire facial image from said camera; d. adjusting said camera to pick up the entire facial image free of extraneous matter not required for creating said data base; e. digitizing and electrical signals corresponding to said entire facial image form the sensors of said camera; f. initializing specific image parameters of part of the digitized entire facial image from said camera to produce a preselected partial digitized image to block out other portions of said entire facial images, and g. storing said partial digitized image for use in producing composite facial images when combined with other partial stored digitized partial images.
Claim 2
Dependent Claim
169 words
A process for creating a facial identification data base using a digital data processing system by digitizing and storing partial photographic images of the faces of real people comprising the steps of: a. displaying an entire photographic facial image of a person; b. providing a camera having sensors therein to receive said entire facial image to generate electrical signals corresponding to said facial image; c. visually displaying said entire facial image from said camera; d. adjusting said camera to pick up the entire facial image free of extraneous matter not required for creating said data base; e. digitizing and electrical signals corresponding to said entire facial image form the sensors of said camera; f. initializing specific image parameters of part of the digitized entire facial image from said camera to produce a preselected partial digitized image to block out other portions of said entire facial images, and g. storing said partial digitized image for use in producing composite facial images when combined with other partial stored digitized partial images.
Claim 3
Dependent Claim
33 words
A process as set forth in claim 1 wherein a coded signal for producing a pre-determined signal level is used in the step of blocking out said other portions of said facial image.
Claim 4
Dependent Claim
31 words
A process as set forth in claim 1 wherein a further step includes visually displaying said partial digitized image prior to storing to permit steps for adjusting said partial digitized image.
Claim 5
Dependent Claim
50 words
A process as set forth in claim 3 wherein one of the steps for adjusting said partial digitized image prior to storing includes comparing the signal level of said partial digitized image with a pre-determined and adjustable threshold signal level to indicate the presence and absence of the partial image.
Claim 6
Dependent Claim
71 words
A process as set forth in claim 4 wherein incoming signals including said partial digitized image are used in said step of comparing so that said incoming signals that are equal to or exceeding said threshold level, indicating non-image and background data, are converted to said pre-determined signal level by said coded signal, with the incoming signals that are below said threshold level signal indicating partial image data are subsequently stored.
Claim 7
Dependent Claim
27 words
A process as set forth in claim 5 wherein an additional step includes assigning a name to said partial digitized image prior to said step of storing.
Claim 8
Dependent Claim
28 words
A process as set forth in claim 6 wherein an additional step includes storing said partial digitized image on a hard disk in said facial identification data base.
Claim 9
Dependent Claim
26 words
The process as set forth in claim 7 wherein a plurality of partial digitized images are derived and stored from a plurality of entire facial images.
Claim 10
Dependent Claim
30 words
The process as set forth in claim 8 wherein said plurality of partial digitized images represent sections of said plurality of facial images including eyes, noses, mouths, foreheads and chins.
