Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
37 words
An image processing method for reproducing a larger image than an original image by enlarging image data of divisional areas of the original image and sequentially printing out the enlarged divisional image data on respective print sheets.
Claim 2
Dependent Claim
37 words
An image processing method for reproducing a larger image than an original image by enlarging image data of divisional areas of the original image and sequentially printing out the enlarged divisional image data on respective print sheets.
Claim 3
Dependent Claim
34 words
An image processing method according to claim 1 wherein a memory storing the original image therein is sequentially addressed so that the image data of the respective divisional areas are read out and enlarged.
Claim 4
Dependent Claim
28 words
An image processing method according to claim 1 wherein identification data for each of the divisional areas of the original image is printed out on each print sheet.
Claim 5
Dependent Claim
23 words
An image processing method according to claim 3 wherein the identification data is printed out on a margin area of each print sheet.
Claim 6
Dependent Claim
22 words
An image processing method according to claim 1, 9 or 12, wherein an image printed on each print sheet is partially overlapped.
Claim 7
Dependent Claim
24 words
An image processing method according to claim 1, 9 or 12, wherein the image data of the original image is enlarged and then dither-processed.
Claim 8
Dependent Claim
41 words
An image processing method according to claim 4 wherein the printout is done by an electrographic laser beam printer and the margin area is determined in synchronism with a beam scan timing of said laser beam printer on a rolled paper.
Claim 9
Dependent Claim
28 words
An image processing method according to claim 7 wherein the printout is done by a color printer having a plurality of drums provided one for each color component.
Claim 10
Dependent Claim
65 words
An image processing method comprising steps of: printing out sequentially divisional areas of an original image on respective sheets; forming a margin area of a predetermined width on the respective sheets on which the divisional areas of the original image are printed; and printing out identification data for each of the divisional areas of the original image on the margin area of the respective sheets.
Claim 11
Dependent Claim
65 words
An image processing method comprising steps of: printing out sequentially divisional areas of an original image on respective sheets; forming a margin area of a predetermined width on the respective sheets on which the divisional areas of the original image are printed; and printing out identification data for each of the divisional areas of the original image on the margin area of the respective sheets.
Claim 12
Dependent Claim
23 words
A method according to claim 1, wherein the divisional areas of the original image are determined on the basis of a magnification ratio.
Claim 13
Dependent Claim
15 words
A method according to claim 3 or 4, wherein said identification data is character data.
Claim 14
Dependent Claim
79 words
An image processing method comprising steps of: printing out a plurality of divisional areas of an original image on respective print sheets such that when the respective print sheets are appropriately arranged, the original image is formed in its entirety; and printing out an image associated with the divisional areas of the original image on the respective print sheets so that the image printed on each sheet is partially overlapped to facilitate the arrangement of the respective print sheets.
Claim 15
Dependent Claim
79 words
An image processing method comprising steps of: printing out a plurality of divisional areas of an original image on respective print sheets such that when the respective print sheets are appropriately arranged, the original image is formed in its entirety; and printing out an image associated with the divisional areas of the original image on the respective print sheets so that the image printed on each sheet is partially overlapped to facilitate the arrangement of the respective print sheets.
Claim 16
Dependent Claim
32 words
A method according to claim 1 or 9, wherein the margin of a predetermined width is formed on the print sheets on which the divisional areas of the original image are printed.
Claim 17
Dependent Claim
29 words

Claim 18
Dependent Claim
32 words
An imaged processing method according to claim 4 or 9, wherein the margin area on which the identification data is printed out is formed in a longitudinal direction or/and a transverse direction.
Claim 19
Dependent Claim
47 words

Claim 20
Dependent Claim
47 words
An image processing apparatus, comprising: process means for processing image data of a divisional area of an original image to enlarge the original image; and means for sequentially printing out the enlarged divisional area in accordance with the data processed by said process means on respective sheets.
Claim 21
Dependent Claim
28 words
An image processing apparatus according to claim 16, wherein identification data for each of the divisional areas of the original image is printed out on each print sheet.
Claim 22
Dependent Claim
23 words
An image processing apparatus according to claim 16, wherein the identification data is printed out on a margin area of each print sheet.
Claim 23
Dependent Claim
19 words
An imaged processing apparatus according to claim 16, wherein an image printed on each print sheet is partially overlapped.
