Abstract

PURPOSE:To prevent the data extracting mistakes by providing the history of affections of the 2-dimensional coordinate value delivered outside as the coordinates data against an external system as the drawing data. CONSTITUTION:The picture data (a) obtained from outside is stored in an image memory 1. A vector generating part 2 produces a vector on an image memory 3 based on the drawing data (b) given from outside and produces the picture data (d). A pattern to be measured is attached on a digitizer board 7 and the points to be measured are pointed by an accessory cursor, etc., for the coordinates on a pattern. Thus the 2-dimensional coordinates of the pointed point are turned into the form of the digital data that can be utilized by a computer and delivered as the coordinate data C. A window segmenting part 3 segments the sizes that can be displayed at a graphic display part 5 out of data a' and b' stored in both memories 1 and 3 and gives these sizes to the part 5.
