ABSTRACT:
This invention is a color scanner comprising an image reading means for reading an original stored in an original cassette by carrying out of a rough-scanning or main scanning, a signal processing means for signal-processing the main scan data of said original, which the main scan data obtained by said image reading means, a calculation setting means for obtaining characteristic values of said original on the basis of rough-scan data obtained by said rough-scanning, calculating original classification informations on the basis of the characteristic values, setting a signal processing conditions into said signal processing means, and outputting a certainty factor, an input means for inputting supplemental informations necessary when said certainty factor is low, and a recording means for recording the image on the basis of the output of the signal processing means. This invention relates to a method thereof. This invention is a color scanner comprising an input section for scanning and reading an original while conducting color separation, an original storage and transporting section having an original storage portion, said original storing and transporting section being capable of automatically transporting said original from said storage portion to said input section, image processing section for performing image processing on the basis of color separation signals from said input section so as to produce halftone signals, an output section for producing and outputting a halftone film from said halftone signals, and automatic condition setting section for determining processing conditions on the basis of the rough-scan data from said image processing section and for setting set-up parameters of said image processing section.
