Abstract
Abstract A light image of an object to be recognized is scanned in a series of narrow elongated laterally displaced parallel areas. Photoelectric means responds successively to the overall light from successive areas and produces corresponding signals. These signals are converted to corresponding digital values. The resultant digital representation of the object may be compared by a computer with digital representations of other objects obtained in the same manner to determine whether they are like or unlike.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
Apparatus for producing a digital representation of an object to be recognized by comparing its digital representation to a set of digital representations of known objects which comprises means for producing a two-dimensional light image of an object field, scanning means for scanning said two-dimensional light image in a series of narrow elongated laterally displaced side-by-side areas, the lengths of said elongated areas extending across one dimension of the scanned area of said light image and the laterally displaced elongated areas extending across the other dimension of said scanned area, photoelectric means responsive successively to the overall light from successive narrow elongated areas in said series for producing signals successively representing the successive values of said overall light, and means for producing a digital value corresponding to each produced signal such that all of the produced digital values together are a digital representation of the object to be recognized.
Claim 2
Dependent Claim
149 words
Apparatus for producing a digital representation of an object to be recognized by comparing its digital representation to a set of digital representations of known objects which comprises means for producing a two-dimensional light image of an object field, scanning means for scanning said two-dimensional light image in a series of narrow elongated laterally displaced side-by-side areas, the lengths of said elongated areas extending across one dimension of the scanned area of said light image and the laterally displaced elongated areas extending across the other dimension of said scanned area, photoelectric means responsive successively to the overall light from successive narrow elongated areas in said series for producing signals successively representing the successive values of said overall light, and means for producing a digital value corresponding to each produced signal such that all of the produced digital values together are a digital representation of the object to be recognized.
Claim 3
Dependent Claim
29 words
Apparatus according to claim 1 in which said scanning means scans said series of narrow elongated areas incrementally, and said photoelectric means produces signals corresponding to successive incremental areas.
Claim 4
Dependent Claim
53 words
Apparatus according to claim 1 in which said scanning means includes a mask having a narrow elongated slit therein, said mask and light image being relatively movable in a direction lateral to the length of said slit to supply light from successive narrow elongated areas of said light image to said photoelectric means.
Claim 5
Dependent Claim
31 words
Apparatus according to claim 3 including a display screen, said light image being produced on said display screen and said mask being positioned between the display screen and said photoelectric means.
Claim 6
Dependent Claim
39 words
Apparatus according to claim 4 including means for adjusting the size of said light image on said display screen, whereby the width of the object to be recognized may be adjusted to correspond to the length of said slit.
Claim 7
Independent Claim
134 words
The method of producing a digital representation of an object to be recognized by comparing its digital representation to a set of digital representations of known objects which comprises producing a two-dimensional light image of said object, scanning said two-dimensional light image in a series of narrow elongated laterally displaced side-by-side areas, the lengths of said elongated areas extending across one dimension of the scanned area of said light image and the laterally displaced elongated areas extending across the other dimension of said scanned area, photoelectrically producing signals successively representing the successive values of the overall light from successive narrow elongated areas in said series, and producing a digital value corresponding to each produced signal such that all of the produced digital values together are a digital representation of the object to be recognized.
Claim 8
