PURPOSE:To ensure simple and accurate separation between rectilinear and circular arc sections by using a contour point train data producing device, a separating point extracting device, and a contiguous segment checking device. CONSTITUTION:Image inputted from an image input device 1 is given to a contour point string data producing device 3 via a binarizing device 2 to undergo edge tracing and chain coding processes. The chain-coded contour point string data is stored in a memory 4 and undergoes the calculation of its feature value via a feature value calculating device 5. Data on a feature value calculated by the device 5 is inputted to a separating point extracting device 6. Information on a separating point extracted by the means 6 is inputted to a segment approximating device 7 for production of a rectilinear or circular arc approximate pattern. The information on the segment approximated by the device 7 is inputted to a contiguous segment checking device 8. The device 8 takes out the contiguous segments and deletes the separating point to form both segments in the single one as long as both segments are equal to each other. |
