Abstract
Abstract A method for recording color separation picture images and an outline image simultaneously for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein a plurality of color separation picture signals and an outline signal are obtained by scanning an original picture photoelectrically, wherein the outline signal is stored in a memory together with the color separation picture signals, in parallel, and then the stored signals are read out of the memory, in series, and wherein an exposure scanning means is controlled by the readout signals, thereby recording color separation picture images and an outline image on a photosensitive material in the same time.

Claim 1
Independent Claim
102 words
A method for recording color separation picture images and an outline image simultaneously for use in a picture reproducing machine, comprising the steps of: (a) obtaining a plurality of color separation picture signals and an outline signal by scanning an original picture photoelectrically; (b) storing the color separation picture signals and the outline signal into a memory, in parallel; (c) reading the color separation picture signals and the outline signal out of the memory, in series; and (d) controlling an exposure scanning means by the readout signals, thereby simultaneously recording color separation picture images and an outline image on a photosensitive material.
Claim 2
Independent Claim
102 words
A method for recording color separation picture images and an outline image simultaneously for use in a picture reproducing machine, comprising the steps of: (a) obtaining a plurality of color separation picture signals and an outline signal by scanning an original picture photoelectrically; (b) storing the color separation picture signals and the outline signal into a memory, in parallel; (c) reading the color separation picture signals and the outline signal out of the memory, in series; and (d) controlling an exposure scanning means by the readout signals, thereby simultaneously recording color separation picture images and an outline image on a photosensitive material.
Claim 3
Dependent Claim
29 words
A method as defined in claim 1, wherein the outline signal is obtained from a sharp signal and an unsharp signal which are obtained by scanning the original picture.
Claim 4
Dependent Claim
34 words
A method as defined in claim 1, wherein the outline signal is obtained by detecting a particular color tone by which the background or the object portion of the original picture is smeared out.
