Abstract
Abstract A video system for storing high resolution still images has a camera which produces separate video signals each representing a separate color component image. These image signals are recorded separately and during retrieval sequentially played back. Each image signal is temporarily stored and then simultaneously displayed to form a high resolution image.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
171 words
In combination: apparatus for supplying video signals having serial-in-time segments cyclically descriptive of first, second and third color component image fields, each segment comprising a succession of digitized pixel values; first, second and third random-access memories, each having respective storage locations sufficient in number to store the pixels of any image field; means for writing the successive digitized pixel values of the video signal segment descriptive of said first color component image field into said first random-access memory; means for writing the successive digitized pixel values of the video signal segment descriptive of said second color component image field into said second random-access memory; means for writing the successive digitized pixel values of the video signal segment descriptive of said third color component image field into said third random-access memory; means for repeatedly field scanning the storage locations of said first, second and third random-access memories parallelly-in-time to supply respective read-outs; means for converting the read-outs of said first, second and third random-access memories to red, green and blue video signals.
Claim 2
Dependent Claim
171 words
In combination: apparatus for supplying video signals having serial-in-time segments cyclically descriptive of first, second and third color component image fields, each segment comprising a succession of digitized pixel values; first, second and third random-access memories, each having respective storage locations sufficient in number to store the pixels of any image field; means for writing the successive digitized pixel values of the video signal segment descriptive of said first color component image field into said first random-access memory; means for writing the successive digitized pixel values of the video signal segment descriptive of said second color component image field into said second random-access memory; means for writing the successive digitized pixel values of the video signal segment descriptive of said third color component image field into said third random-access memory; means for repeatedly field scanning the storage locations of said first, second and third random-access memories parallelly-in-time to supply respective read-outs; means for converting the read-outs of said first, second and third random-access memories to red, green and blue video signals.
Claim 3
Dependent Claim
33 words
A combination as set forth in claim 1 wherein said apparatus for supplying video signals provides them by playing back from a recording, which playing back is subject to some time base variation.
Claim 4
Dependent Claim
23 words
A combination as set forth in claim 1 wherein said first, second and third color components are red, green and blue components respectively.
Claim 5
Dependent Claim
23 words
A combination as set forth in claim 1 wherein said first, second and third color components are red, green and luminance components respectively.
Claim 6
Dependent Claim
23 words
A combination as set forth in claim 1 wherein said first, second and third color components are red, blue and luminance components respectively.
Claim 7
Dependent Claim
23 words
A combination as set forth in claim 1 wherein said first, second and third color components are green, blue and luminance components respectively.
Claim 8
Dependent Claim
145 words
In combination: apparatus for supplying video signals having serial-in-time segments cyclically descriptive of first, second, third and fourth color component image fields, each segment comprising a succession of digitized pixel values, one of said color component fields being a weighted summation of the other color component fields; first, second and third random-access memories, each having respective storage locations sufficient in number to store the pixels of any image field; means for writing the successive digitized pixel values of three selected ones of the four video signal segments into said first random-access memory, into said second random-access memory, and into said third random-access memory, respectively; means for repeatedly field scanning the storage locations of said first, second and third random-access memories parallelly-in-time to supply respective read-outs; means for converting the read-outs of said first, second and third random-access memories to red, green and blue video signals.
Claim 9
Dependent Claim
145 words
In combination: apparatus for supplying video signals having serial-in-time segments cyclically descriptive of first, second, third and fourth color component image fields, each segment comprising a succession of digitized pixel values, one of said color component fields being a weighted summation of the other color component fields; first, second and third random-access memories, each having respective storage locations sufficient in number to store the pixels of any image field; means for writing the successive digitized pixel values of three selected ones of the four video signal segments into said first random-access memory, into said second random-access memory, and into said third random-access memory, respectively; means for repeatedly field scanning the storage locations of said first, second and third random-access memories parallelly-in-time to supply respective read-outs; means for converting the read-outs of said first, second and third random-access memories to red, green and blue video signals.
Claim 10
Dependent Claim
33 words
A combination as set forth in claim 7 wherein said apparatus for supplying video signals provides them by playing back from a recording, which playing back is subject to some time base variation.
