Abstract
Abstract An image processing apparatus for changing an image size wherein the document is marked with two kinds of color markers differing in color so as to be designated a pre-change region in which an image size is to be changed and a post-change region indicating a region after the image size has been changed. The apparatus comprises a condition detector to detect the pre-change region and the post-change region and obtains a magnification of the image size change on the basis of the pre-change region and the post-change region.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
143 words
An image processing apparatus for changing an image size, comprising: an image reader to scan a document to photoelectrically read an original image and to generate color image signals, wherein the document is marked with two kinds of color markers differing in color to designate a pre-change region in which an image size is to be changed and a post-change region indicating a region after the image size has been changed, the pre-change region and the post-change region being designated by double-looped marked lines differing in color; a condition detector to detect the pre-change region and the post-change region from the color image signals and to obtain a magnification of the image size change on the basis of the pre-change region and the post-change region; and a magnification processor to process image signals to change the image size in accordance with the magnification.
Claim 2
Dependent Claim
143 words
An image processing apparatus for changing an image size, comprising: an image reader to scan a document to photoelectrically read an original image and to generate color image signals, wherein the document is marked with two kinds of color markers differing in color to designate a pre-change region in which an image size is to be changed and a post-change region indicating a region after the image size has been changed, the pre-change region and the post-change region being designated by double-looped marked lines differing in color; a condition detector to detect the pre-change region and the post-change region from the color image signals and to obtain a magnification of the image size change on the basis of the pre-change region and the post-change region; and a magnification processor to process image signals to change the image size in accordance with the magnification.
Claim 3
Dependent Claim
54 words
The apparatus of claim 2, wherein the condition detector comprises a size detector to detect the dimensions of the double loops in both primary and sub scanning directions, and the condition detector obtains the magnifications in both the primary and sub scanning directions on the basis of the dimensions obtained from the double loops.
