An image converting apparatus for converting document data constituted by containing plural sorts of draw objects into image data constituted by a plurality of pixel data, comprising: first conversion means for converting said document data into first image data; second conversion means for converting said first image data into second image data; and a plurality of tables provided in correspondence with at least one of plural sorts of draw objects containing information to which the image converting apparatus refers when said first image data acquired by converting the sort of draw object corresponding thereto is converted into said second image data; wherein: said second conversion means includes: area unit conversion means, as to each of areas obtained by subdividing said first image data by plural number, for converting first image data of said area into second image data, while referring to said table corresponding to a sort of draw object contained in said area; pixel unit conversion means, as to each of pixel data constituting said first image data, for converting said pixel data into second image data, while referring to said table corresponding to a sort of draw object indicated by said pixel data; and conversion switching means for applying said pixel unit conversion means to such an area wherein at least two said tables are corresponded to sorts of draw objects contained therein, and for applying said area unit conversion means to such an area wherein one said table is corresponded to a sort of a draw object contained therein or to such an area containing no draw object, within said first image data. <IMAGE> |
