Abstract
Abstract A method for producing photographic stills comprises producing a video signal by electronic high resolution scanning of the object to be photographed, writing the video signal into intermediate storage and reading the signal out of intermediate storage to write a photographic still, the time for writing the video signal into intermediate storage being shorter than the time for writing the still. An apparatus for producing photographic stills includes a electronic camera tube and a permanent storage means into which the video signal provided by the camera is written more rapidly than it is read out. The apparatus may also include an inverting video signal storage unit and associated repetition generator.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
116 words
A method for producing and processing photographic quality video signals comprising the steps of: converting an optical image into a video signal by high resolution electronic scanning at a scanning rate of at least about 1,000 lines per image wherein the exposure time for producing the video signal is less than about 10 milliseconds; writing said video signal into intermediate storage, the time for writing said video signal into intermediate storage being less than about 40 milliseconds; and, reading said video signal out of intermediate storage into permanent storage, the time for writing the video signal into intermediate storage being shorter than the time for reading the video signal out of intermediate storage into permanent storage.
Claim 2
Independent Claim
116 words
A method for producing and processing photographic quality video signals comprising the steps of: converting an optical image into a video signal by high resolution electronic scanning at a scanning rate of at least about 1,000 lines per image wherein the exposure time for producing the video signal is less than about 10 milliseconds; writing said video signal into intermediate storage, the time for writing said video signal into intermediate storage being less than about 40 milliseconds; and, reading said video signal out of intermediate storage into permanent storage, the time for writing the video signal into intermediate storage being shorter than the time for reading the video signal out of intermediate storage into permanent storage.
Claim 3
Independent Claim
133 words
A method of producing a photographic still by producing an optical image of the photographed object during a usual short exposure time, in which an electric charge pattern corresponding to the image is maintained beyond the end of the exposure and is converted by a single electronic high resolution scan at a scanning rate of at least 1,000 lines per image into a video signal which is intermediately stored, the time for completely scanning the charge pattern of one image and intermediately storing the corresponding video signal being less than about 40 milliseconds, in which the intermediately stored video signal is permanently stored, the time for writing the signal into intermediate storage being shorter than for writing into permanent storage, and in which the still is written by the permanently stored video signal.
Claim 4
Independent Claim
133 words
A method of producing a photographic still by producing an optical image of the photographed object during a usual short exposure time, in which an electric charge pattern corresponding to the image is maintained beyond the end of the exposure and is converted by a single electronic high resolution scan at a scanning rate of at least 1,000 lines per image into a video signal which is intermediately stored, the time for completely scanning the charge pattern of one image and intermediately storing the corresponding video signal being less than about 40 milliseconds, in which the intermediately stored video signal is permanently stored, the time for writing the signal into intermediate storage being shorter than for writing into permanent storage, and in which the still is written by the permanently stored video signal.
