Claims

[Scope of Claim for Utility Model Registration] A manuscript reading means for scanning a manuscript to read image information, a first storage means for storing manuscript picture information read by the manuscript reading means, and coordinates of a sampling frame for the manuscript picture information. a sampling area specifying means for specifying a value;
A second storage means stores the coordinate values of the sampling frame designated by the designation means, and only the image information area of the first storage means specified by the coordinate values stored in the second storage means is read out, and other image information areas are read out. In an image processing apparatus equipped with an image information extraction means for transferring to a data processing section, when the original image reading means reads a document with a sampling area surrounded by a frame line, the image information of the image information in the first storage means is transferred to the second storage means. A certain area centered around the coordinate values of the sampling frame stored in the storage means is searched, and on the condition that a certain number or more of black pixel data are continuous in the main scanning direction and the sub-scanning direction, it is regarded as a frame line, and the a detection means for detecting the coordinate value of the frame line; a comparison/calculation means for comparing the coordinate value of the frame line detected by the detection means with the coordinate value of the sampling frame in the second storage means and calculating the difference; Based on the calculation data of the comparison/calculation means, the second
1. A correction device for an image sampling area, comprising a correction means for correcting coordinate values of a sampling frame in a storage means.
