Abstract

An image processing apparatus obtains an exact distance of a marking portion shown on a document image based upon a magnification (reduction) shown on a document image such as a map. etc. following the sequence of processes as mentioned below. First, a reduction value and a marking portion are recognized from an image data of a document image, and the marking portion is combined with the image data. Next, a dimension of the marking portion is obtained, and the exact distance of the marking portion is calculated based upon the obtained dimension and the reduction value. Then, after the distance value has been combined with the image data, the image data is outputted (copied). By adopting the processes, for example, in the case where an exact distance of a predetermined interval on the map is expected to be obtained, the desired distance value is shown in an outputted image only by preliminarily describing a marking on a specified interval in the document image. This makes it possible to improve added value of the apparatus when the image processing apparatus is applied to a digital copying machine and the like.

Claims6

Dependent claims

An image processing apparatus comprising:

image input means for reading a document image;
area specifying means for specifying an arbitrary area in the document image read by said image input means;
interval specifying means for specifying arbitrary intervals in the document image;
dimension calculating means for calculating a dimension of the intervals;
dimension input means for inputting a prescribed dimension of the intervals;
ratio calculating means for calculating a ratio of the calculated dimension to the prescribed dimension;
first magnification setting means for setting a reciprocal of the ratio as a first magnification of the specified area which has been specified by said area specifying means;
first conversion means for converting a size of a first image within the specified area in accordance with the first magnification;
second magnification setting means for setting a second magnification of an unspecified area so that a second image in the unspecified area does not exceed a predetermined size of sheets, the unspecified area being other than the specified area on a sheet of a predetermined size which is provided for the first image whose size has been converted by said first conversion means;
second conversion means for converting the size of the second image in accordance with the second magnification;
and
combining means for combining image data of both the images whose sizes have been converted by said first and said second conversion means.
