Abstract
Abstract An original divided in a plurality of regions is photoelectrically scanned and its reproduction is then recorded. Signals from a plurality of photodetectors arranged to detect each desired common region of the original in accordance with a signal representing its corresponding scanning position and its corresponding signal stored in advance in a memory device are selectively switched over and output to the recording side in accordance with sequential scanning of the plurality of regions in the original. The above method assures high productivity without need for special skill or expensive facilities.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A picture scanning and recording method, wherein said method includes: placing an original picture, having a plurality of regions, on a recording drum, arranging a plurality of photodetectors to detect each region of the original picture, scanning photoelectrically the original picture and generating a plurality of picture signals and pulse values, processing each picture signal into at least two different processed signals, and selecting, depending upon a comparison of the pulse value and preset data stored in a memory, which processed signal is to be outputted to a recording head.
Claim 2
Dependent Claim
90 words
A picture scanning and recording method, wherein said method includes: placing an original picture, having a plurality of regions, on a recording drum, arranging a plurality of photodetectors to detect each region of the original picture, scanning photoelectrically the original picture and generating a plurality of picture signals and pulse values, processing each picture signal into at least two different processed signals, and selecting, depending upon a comparison of the pulse value and preset data stored in a memory, which processed signal is to be outputted to a recording head.
Claim 3
Dependent Claim
26 words
A picture scanning and recording method as claimed in claim 1, wherein said method includes a further step of determining character regions from picture pattern regions.
Claim 4
Dependent Claim
24 words
A picture scanning and recording method as claimed in claim 1, wherein said scanning step further includes scanning at various detection and resolution levels.
Claim 5
Dependent Claim
51 words
A picture scanning and recording method as claimed in claim 1, wherein said method includes a further step of outputting signals for at least one character region, produced in accordance with line signals of high resolution, and at least one continuous picture image region, produced as a color-separated halftone dot image.
Claim 6
Dependent Claim
70 words
A picture scanning and recording method as claimed in claim 1, wherein said method includes a further step of designating, by preset data stored in a memory, regions requiring reporduction conditions different from those required for other regions of the plurality of regions in the original picture, wherein the processed signals of at least two types are switched from one to another as scanning locations coincided with the preset data.
