Abstract
Abstract An image outputting device includes a pattern generation for impressing a picture element reference pattern on a recorded document along with the picture information thereof, where the reference pattern is in phase with the recorded picture elements. When such a recorded document is used as an input original, the phase of each read out picture element is made coincident with that of the corresponding picture element on the original, to prevent deterioration of the image due to phase shifting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
An image outputting device for outputting an image of an original containing a reference pattern comprising: means for reading each picture element of an original and for obtaining serial image signals of areas of said original other than the area containing said reference pattern, said reading being performed through main scanning and sub-scanning; pattern generation means for generating reference pattern signals at a timing in accordance with prearranged picture element positions on a scanning line corresponding to said reference pattern; means for producing combined image signals by combining said serial image signals with said reference pattern signals; and means for reproducing said combined image signals on a recording medium as a visible image including a reproduced reference pattern to thereby reproduce said original including said reference pattern on said recording medium and to enable subsequent reproduction from said recording medium.
Claim 2
Dependent Claim
140 words
An image outputting device for outputting an image of an original containing a reference pattern comprising: means for reading each picture element of an original and for obtaining serial image signals of areas of said original other than the area containing said reference pattern, said reading being performed through main scanning and sub-scanning; pattern generation means for generating reference pattern signals at a timing in accordance with prearranged picture element positions on a scanning line corresponding to said reference pattern; means for producing combined image signals by combining said serial image signals with said reference pattern signals; and means for reproducing said combined image signals on a recording medium as a visible image including a reproduced reference pattern to thereby reproduce said original including said reference pattern on said recording medium and to enable subsequent reproduction from said recording medium.
Claim 3
Dependent Claim
20 words
An image outputting device as claimed in claim 1, further including memory means for temporarily storing said serial image signals.
Claim 4
Dependent Claim
55 words
An image outputting device as claimed in claim 1, said reading means initially scanning at a high scanning line density until said reference pattern is reached, and thereupon assuming a predetermined scanning pitch, whereby the phase of the read out picture elements is rendered coincident with that of the corresponding picture elements on said original.
Claim 5
Dependent Claim
56 words
An image outputting device as claimed in claims 1 or 3, further comprising means for temporary storage of said serial image signals and including a memory, and control means controlling reading from said memory, said combining means comprising gate means receiving image signals output via said control means, and an output of said pattern generating means.
Claim 6
Dependent Claim
29 words
An image outputting device as claimed in claim 4, said control means including means for inhibiting operation of said pattern generation means to prevent output of said reference pattern.
Claim 7
Dependent Claim
31 words
An image outputting device as claimed in claim 1, including memory means for storing said image signals, an output of said reading means lacking any signal corresponding to said reference pattern.
Claim 8
Dependent Claim
16 words
An image outputting device as claimed in claim 1, said reproducing means comprising a xerography device.
Claim 9
Dependent Claim
35 words
An image outputting device as claimed in claim 1, wherein said reference pattern signals comprise plural bit signals repeated for each scanning cycle and forming an image pattern arranged along both main and sub-scanning direction.
