Abstract
Abstract Pattern information for production of a Jacquard pattern by a knitting or a weaving machine is automatically and quickly obtained. A pattern drawn on a sheet by a designer is converted to an analog type electrical signal by a television camera, and said analog signal is converted to a digital signal according to each color of each picture element. Said digital signal is stored in a digital memory. After the edition of said digital signal in the memory, the digital signal which defines the color of each picture element is applied to a knitting or a weaving machine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
A pattern generating system for providing pattern information to produce a Jacquard pattern for a knitting or weaving machine comprising a television camera for converting the pattern of an objective being analyzed to analog signals, said television camera scanning individual lines and having a flyback time between lines, a plurality of comparators for dividing said analog signals into a plurality of partial signals in accordance with the amplitude of said analog signals, a code converter connected to said comparators for converting each of said partial signals into digital signals, digital memory means for storing said digital signals, output means for providing pattern information to the knitting or weaving machine in accordance with the digital signals stored by said digital memory means, said digital memory means including a buffer register and a memory unit, said buffer register being connected to said code converter for storing in said buffer register digital signals corresponding to one scanned line as each line is being scanned by said television camera, and means for transferring said one scanned line digital signals from said buffer register to said memory unit during a flyback time.
Claim 2
Dependent Claim
187 words
A pattern generating system for providing pattern information to produce a Jacquard pattern for a knitting or weaving machine comprising a television camera for converting the pattern of an objective being analyzed to analog signals, said television camera scanning individual lines and having a flyback time between lines, a plurality of comparators for dividing said analog signals into a plurality of partial signals in accordance with the amplitude of said analog signals, a code converter connected to said comparators for converting each of said partial signals into digital signals, digital memory means for storing said digital signals, output means for providing pattern information to the knitting or weaving machine in accordance with the digital signals stored by said digital memory means, said digital memory means including a buffer register and a memory unit, said buffer register being connected to said code converter for storing in said buffer register digital signals corresponding to one scanned line as each line is being scanned by said television camera, and means for transferring said one scanned line digital signals from said buffer register to said memory unit during a flyback time.
Claim 3
Dependent Claim
54 words
The pattern generating system as set forth in claim 1 wherein said memory unit is a random access integrated circuit memory unit and said buffer register and said memory unit are coupled in series circuit whereby said digital signals are stored in said memory unit synchronously with the line scanning of said television camera.
Claim 4
Dependent Claim

Claim 9
Dependent Claim
26 words
The pattern generating system as set forth in claim 2 wherein said digital signals comprise one of the color specifying signals from said color television camera.
Claim 10
Dependent Claim
54 words
The pattern generating system as set forth in claim 8 wherein said system further includes a display for monitoring simulated color signals, said display receiving said color signals from a color specifying matrix, said color specifying matrix receiving said color specifying signals and three primary color picture signals supplied from a color signal generator.
Claim 11
Dependent Claim
26 words
The pattern generating system as set forth in claim 4 wherein said system further includes a color filter located between said television camera and said objective.
