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; a display unit adapted to display plural items of object information; a selecting unit adapted to select, based on an instruction from a user, predetermined object information from among the plural items of displayed objection information; a determination unit adapted to determine whether information similar to the predetermined object information selected by using said selecting unit is contained in the vector data generated by said vectorization unit; a storage unit adapted to store the vector data when said determination unit determines that information similar to the predetermined object information is contained in the vector data, while it does not store the vector data when said determination unit determines that information similar to the predetermined object information is not contained in the vector data; and a segmentation unit adapted to segment the image information into a plurality of objects, wherein said determination unit determines independently for each of the objects segmented by said segmentation unit whether information similar to the predetermined object information is contained.
