Abstract

PURPOSE:To extract a boundary line without having all image data by providing an image data input part, temporary storage part, boundary line element extraction part, boundary line element connection part, and boundary line block connection part. CONSTITUTION:The boundary line element extraction part 10 reads two-line data out of the temporary storage part 9 from left by four picture elements sequentially and checks the pattern to extract a boundary line element. The boundary line element connection part 11 connects the boundary line element obtained by the extraction part 10 to a boundary line element block formed of boundary line elements which are already obtained by the extraction part 10 to generate a new boundary line element block. The boundary line element block connection part 13 checks the terminal points of the boundary line element blocks formed by the connection part 11 to find other boundary line element blocks which can be connected, and adds connection information to both boundary line element blocks. A boundary dot array generation part 14 generates a boundary dot array on the basis of the connection information added to said boundary line element blocks.
