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.
