Abstract
Abstract A photographic system where a still camera (21) and a video camera (20) are employed to view and photograph an object. The video camera (20) is employed to capture images of an object and each image is combined with a unique code. The still camera (21) produces latent images correspondingly coded and the video images may be printed or displayed on an image printer (23) to enable a selection of desired prints to be made without the need to process the film of the still camera (21) to provide proofs.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
170 words
A system including a first camera for producing latent images of an object on film which may subsequently be processed; a second camera integral with or adjacent the first camera adapted to produce images substantially corresponding to the latent images of the first camera whereby respective images of the second camera correspond to respective latent images of the first camera; coding means including at least one light emitting display associated with the first camera for uniquely coding each said latent image, said coding means correspondingly coding the images produced by the second camera, said coding means further including a counter for providing in response to a release signal a code indicative of the number of latent images produced, an identification code matrix for producing a user code indicative of a particular user, a mixer for combining the latent image code and the user code, and drivers for driving said light emitting display; and, image display means for displaying or providing viewable images of the images produced by the second camera.
Claim 2
Independent Claim
170 words
A system including a first camera for producing latent images of an object on film which may subsequently be processed; a second camera integral with or adjacent the first camera adapted to produce images substantially corresponding to the latent images of the first camera whereby respective images of the second camera correspond to respective latent images of the first camera; coding means including at least one light emitting display associated with the first camera for uniquely coding each said latent image, said coding means correspondingly coding the images produced by the second camera, said coding means further including a counter for providing in response to a release signal a code indicative of the number of latent images produced, an identification code matrix for producing a user code indicative of a particular user, a mixer for combining the latent image code and the user code, and drivers for driving said light emitting display; and, image display means for displaying or providing viewable images of the images produced by the second camera.
Claim 3
Dependent Claim
21 words
The system of claim 1, wherein said first camera is a still camera and said second camera is a video camera.
Claim 4
Dependent Claim
14 words
The system of claim 2, wherein said image display means comprises a thermal printer.
Claim 5
Dependent Claim
35 words
The system of claim 3, wherein said one light emitting display is mounted within said first camera adjacent film therein and is strobed or switched to impress a unique code on each said latent image.
Claim 6
Dependent Claim
47 words
The system of claim 4, wherein said coding means includes two light emitting displays, and wherein one of said displays is arranged to be visible to the user and is lit when the system is in use, such that the codes displayed by the two displays correspond.
Claim 7
Dependent Claim
15 words
The system of claim 1, including an oscillator for providing timing pulses for said counter.
Claim 8
Dependent Claim
20 words
The system of claim 1, including an exposure timer for timing a strobe period for said one light emitting display.
Claim 9
Dependent Claim
40 words
The system of claim 5, wherein said light emitting displays comprise seven segment diode displays having seven digits, some of said digits being for the display of the user code and some for the display of the latent image code.
Claim 10
Dependent Claim
51 words
The system of claim 3, including a memory for storing said latent image code and said user code, read and write switching networks for reading and writing from the memory, a read-write control circuit for controlling the switching networks, said read switching network receiving read addressing data and providing read data.
Claim 11
Dependent Claim
50 words
The system of claim 9, including a video text generator for receiving read data from the read switching network and for providing character line data, and an address generation and timing circuit for providing line address data to the text generator and read address data to the read switching network.
Claim 12
Dependent Claim
26 words
The system of claim 10, including a sync pulse separator for separating vertical and horizontal sync pulses from a video signal derived from the video camera.
Claim 13
Dependent Claim
24 words
The system of claim 11, including a window generator providing a window signal for blanking video information from a portion of the video signal.
Claim 14
Dependent Claim
68 words
The system of claim 12, wherein said address generator and timing circuit and said window generator are controlled by the vertical and horizontal sync pulses separated from the video signal and said system further includes a mixer for combining said window signal with said video signal and said character data to produce a composite video signal plus a window within which are characters representative of the unique code.
Claim 15
Dependent Claim
16 words
The system of claim 13, wherein said composite video signal is supplied to the thermal printer.
Claim 16
Dependent Claim
27 words
The system of claim 13, wherein said composite video signal is stored in a storage means from which it may subsequently be retrieved for viewing or reproduction.
Claim 17
Dependent Claim
27 words
The system of claim 13, including a serial to parallel converter receiving the character line data and converting it to serial data for supply to the mixer.
Claim 18
Dependent Claim
29 words
The system of claim 10, wherein a memory refresh signal is obtained from an input to the counter and is supplied to the memory to commence a write cycle.
Claim 19
Dependent Claim
43 words
The system of claim 13, wherein said first camera has a shutter release driven be a solenoid, said solenoid derives a delayed control signal from the release signal for triggering the solenoid a predetermined period after the production of the composite video signal.
