Abstract

Abstract A video printer is disclosed. An input video signal is converted into a digital signal and stored in a memory. The write/read operation and memory addresses of the memory are controlled by a memory control unit. The signal read out of the memory is converted into print data, and an image is printed by a printer. The print data and the printing operation are controlled by a print control unit, and at least a part of the memory areas of the memory is controlled in the write operation by an area control unit.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 175 words
A printing apparatus for printing a print of images represented by video signals to provide a print having multiple images thereon, said apparatus comprising: input means for providing video signals representing images to be printed; analog/digital conversion means for converting said video signals from said input means into a digital signals; memory means having a plurality of memory areas for string said digital signals; printing means for printing a print of images represented by said stored digital signals; memory control means for storing a first digital signal in a first memory area of said memory means and storing a second digital signal in a second memory area of said memory means; and print control means for controlling said printing means to print a print having a plurality of print areas, with an image formed from the first stored digital signal printed in a first print area of the print and an image formed from the second stored digital signal printed in a second print area of the print, to provide a print containing multiple images.
Claim 2
Dependent Claim 175 words
A printing apparatus for printing a print of images represented by video signals to provide a print having multiple images thereon, said apparatus comprising: input means for providing video signals representing images to be printed; analog/digital conversion means for converting said video signals from said input means into a digital signals; memory means having a plurality of memory areas for string said digital signals; printing means for printing a print of images represented by said stored digital signals; memory control means for storing a first digital signal in a first memory area of said memory means and storing a second digital signal in a second memory area of said memory means; and print control means for controlling said printing means to print a print having a plurality of print areas, with an image formed from the first stored digital signal printed in a first print area of the print and an image formed from the second stored digital signal printed in a second print area of the print, to provide a print containing multiple images.
Claim 3
Dependent Claim 56 words
A printing apparatus as claimed in claim 1 wherein said memory control means stores the first digital signal in a memory area of said memory means corresponding with a left half of the print and stores the second digital signal in a memory area of said memory means corresponding with a right half of the print.
Claim 4
Dependent Claim 56 words
A printing apparatus as claimed in claim 1 wherein said memory control means stores the first digital signal in a memory area of said memory means corresponding with an upper half of the print and stores the second digital signal in a memory area of said memory means corresponding with a lower half of the print.
Claim 5
Dependent Claim 35 words
A printing apparatus as claimed in claim 1 wherein said memory control means stores identical digital signals as the first digital signal and the second digital signal to provide a print containing multiple identical images.
Claim 6
Dependent Claim 38 words
A printing apparatus as claimed in claim 1 wherein said memory control means stores different digital signals as the first digital signal and the second digital signal to provide a print containing multiple images that are not identical.
Claim 7
Dependent Claim 76 words
A printing apparatus as claimed in claim 1, wherein said input means includes video signal input means for providing a first video signal representative of a video image, character signal input means for providing a second video signal representative of characters, and combining means for combining the first and second video signals, whereby at least one of the first digital signal and the second digital signal includes representations of the characters combined with the video image.
Claim 8
Dependent Claim 18 words
A printing apparatus as claimed in claim 6 wherein said character signal input means comprises a computer terminal.
Claim 9
Dependent Claim 31 words
A printing apparatus as claimed in claim 6 wherein said character signal input means comprises written characters and a video camera for providing a video signal representative of the written characters.
Claim 10
Dependent Claim 98 words
A printing apparatus as claimed in claim 1, wherein said input means includes video signal input means for providing a video signal image, and character signal input means for providing a digital character signal, and wherein said apparatus further comprises combining means for combining a digital signal produced from said video image signal by said analog/digital conversion means and the digital character signal to provide a combined digital signal for storage in said memory means, whereby at least one of the first digital signal and the second digital signal includes representations of characters combined with a video image.
Claim 11
Dependent Claim 18 words
A printing apparatus as claimed in claim 9 wherein said character signal input means comprises a computer terminal.
Claim 12
Dependent Claim 48 words
A printing apparatus as claimed in claim 9 wherein said character signal input means comprises written characters and a video camera for providing a video character signal representative of the written characters, the digital character signal being produced from said video character signal by said analog/digital conversion means.
Claim 13
Dependent Claim 83 words
A printing apparatus as claimed in claim 1, wherein: said memory means comprises buffer memory means for storing a digital signal representing each video pixel of an input video signal, and field memory means; and said control means includes means for storing in said field memory means the digital signals representing 1 of every N of the video pixels whose representations are stored in said buffer memory means, where N is an integer; whereby said apparatus provides a print containing reduced size images.
Claim 14
Dependent Claim 35 words
A printing apparatus as claimed in claim 1 further comprising: digital/analog conversion means for converting the digital signals stored by said memory means into analog signals; and monitor means for displaying the converted analog signal.
