1. An image processing system comprising: an input unit adapted to input image information: a vectorization unit adapted to generate vector data from the image information input by said input unit; an object information input unit adapted to input predetermined object information; a determination unit adapted to determine whether information similar to the object information input by said object information input unit is contained in the vector data generated by said vectorization unit; and a storage unit adapted to, when said determination unit determines that the object information is contained in the vector data, store the vector data in correspondence with specific property information.
