Abstract
Abstract Color separation condition selecting means for setting up color separation conditions to a picture scanning and recording machine such as a color scanner and a color facsimile, wherein input means inputs factors for determining color separation conditions, processing means selectively outputs the most proper color separation conditions or a symbol representing those depending on the input factors, and output means outputs the selected result of the processing means, and wherein the processing means possesses a construction corresponding to a decision tree which is composed of the input factors and the color separation conditions resulting from the input factors.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
Color separation condition selecting means for a picture scanning and recording machine, comprising input means which inputs factors for determining color separation conditions, processing means which selectively outputs an enable signal to enable a device for generating the proper signal representing the color separation conditions depending on the input factors, and output means which outputs the selected result of the processing means, the improvement in that the processing means possesses a construction corresponding to a decision tree which is composed of the input factors and the color separation conditions resulting from the input factors.
Claim 2
Dependent Claim
94 words
Color separation condition selecting means for a picture scanning and recording machine, comprising input means which inputs factors for determining color separation conditions, processing means which selectively outputs an enable signal to enable a device for generating the proper signal representing the color separation conditions depending on the input factors, and output means which outputs the selected result of the processing means, the improvement in that the processing means possesses a construction corresponding to a decision tree which is composed of the input factors and the color separation conditions resulting from the input factors.
Claim 3
Dependent Claim
67 words
