Abstract
Abstract A system for reproducing and recording a plurality of color originals is disclosed which simultaneously scans a series of sections of a scanning field in which there are disposed pictures having different characteristics and changing the set values of color separation and correction circuitry to compensate for these conditions or characteristics. The scanning process is synchronized with the selection of the suitable conditions of color separation and correction to correspond to the type of picture which is being scanned at any given or particular time.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
138 words
A system for reproducing and recording color original pictures by electromechanical and optical scanning comprising a picture scanning device having a scanning field divided into sections, each section being adapted to support an original picture of a group of pictures with the pictures of the group having different characteristics, each original picture of said group being placed into respective sections of the scanning field of the picture scanning device, circuit means for controlling conditions of reproduction, said conditions of reproduction including set values related to the characteristics of said pictures, said circuit means being responsive to respective ones of said sections of said scanning field for setting said conditions of reproduction, and means for controlling said circuit means for changing said set values in synchronism with scanning of said pictures mounted on said sections of said scanning field.
Claim 2
Independent Claim
138 words
A system for reproducing and recording color original pictures by electromechanical and optical scanning comprising a picture scanning device having a scanning field divided into sections, each section being adapted to support an original picture of a group of pictures with the pictures of the group having different characteristics, each original picture of said group being placed into respective sections of the scanning field of the picture scanning device, circuit means for controlling conditions of reproduction, said conditions of reproduction including set values related to the characteristics of said pictures, said circuit means being responsive to respective ones of said sections of said scanning field for setting said conditions of reproduction, and means for controlling said circuit means for changing said set values in synchronism with scanning of said pictures mounted on said sections of said scanning field.
Claim 3
Dependent Claim
91 words
A system as set forth in claim 1, wherein said circuit means comprises a color correction computation circuit having an input and an output, and a gradation control computation circuit having an input and output, photoelectric tube means connected to said input color correction computation circuit and receiving original picture information, said output of said color correction computation circuit being connected through first switch means to said input of said gradation control computation circuit, an exposure head connected to the output of said gradation control computation circuit through second switch means.
Claim 4
Dependent Claim
42 words
A system as set forth in claim 2, wherein said means for controlling said circuit means comprises relay means controlling said first and second switch means, said relay means being operated by a second photoelectric tube means directed toward said original picture.
Claim 5
Dependent Claim
70 words
A system as set forth in claim 1, wherein said means for controlling said circuit means comprises a plurality of field effect transistors, the same one terminal of each of said transistors connected together receiving an input ring counter, the outputs of stages of said ring counter being supplied as inputs to the gate terminals of respective transistors, and section pulses generated as outputs of respective ones of said transistors.
Claim 6
Dependent Claim
33 words
A system as set forth in claim 1, wherein said means for controlling said circuit means comprises a disc having spaced apart slits, section pulses being generated as light passes through said slits.
Claim 7
Dependent Claim
54 words
A system as set forth in claim 1, in which the originals are mounted on a rotating cylinder, wherein said means for controlling said circuit means comprises a one pulse generating ring and plural pulse generating rings synchronously rotated with said original cylinder, said pulse generating rings having outputs combined to form section signals.
