Abstract
Abstract Even a color scanner in small-scale system structure includes a storage unit for storing image picture data of at least one scanning line. The present invention provides a method of recording a picture image composed of a pattern and characters on a process film by one scanning step, by employing the picture image storage unit. Namely, a pattern original and a character original are arranged along a main scanning direction on an original drum. Coordinate positions of the respective originals are subjected to input designation while areas to be imposed by the characters included in pattern regions to be duplicated are subjected to input designation. When the original picture is scanned to be read while a duplicate thereof is simultaneously scanned and recorded, the character original is stored in the picture image storage unit, while character signals are read from the image storage unit in character imposing areas when pattern signals are recorded, so that the character signals are replaced by the pattern signals thereby to be recorded.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
248 words
The method of reproducing a combined image scene which includes both line image and pictorial image portions which comprises forming a first image scene in which the line image portion to be combined is separate from the pictorial image portion with which it is to be combined in the combined image scene, deriving the coordinates of the pixels forming the boundaries of the line image portion and of the pictorial image portion in the combined image scene and storing said coordinates in a first memory, scanning the first image scene pixel by pixel for deriving a signal which is a measure of the intensity level of each pixel and comparing the coordinates of each pixel scanned with the coordinates stored in the first memory, supplying reproducing means with input signals for reproducing the combined image scene in synchronism with the scanning of the first image scene, storing in a second memory the derived signal of each pixel included within the boundaries of the line image portion whose coordinates are stored in the first memory, while transmitting to the reproducing means the signals of each pixel whose coordinates are outside the boundaries of the line image portion whose coordinates are stored in the first memory, and transmitting to the reproducing means the corresponding signal stored in the second memory when the pixel scanned in the first image scene corresponds to a pixel included within the boundaries of the line image whose coordinates are stored in the first memory means.

Claim 3
Dependent Claim
64 words
A method of scanning and recording images in accordance with claim 1, wherein either line image or pictorial image is selectively reproduced by switch-over means when a coordinate value of a scanning point relative to the original coincides with that of a recording point previously stored in the second memory means, said scanning point and recording point being respectively measured by respective pulse-counting means.
Claim 4
Dependent Claim
31 words
A method of scanning and recording images in accordance with claim 1, wherein line image and pictorial image portions of the original are arranged to align along a main scanning direction.
