ABSTRACT:
An image processor accurately executes area separation using small block size image data. The image processor includes a wavelet transforming circuit which converts input image data into a plurality of band-limited image data, and an edge detecting circuit detects edge information in the image data based upon the band-limited image data. A character-area detecting circuit detects character areas in the image data from the distribution of the edge information, and an expansion/contraction circuit unifies the character areas based upon the detected character-area information.
