1. A media recognition system including a processor, a memory, a display unit having a display screen, and an input device, and executing predetermined recognition processing on a supplied media object to output the result of processing to said display screen, comprising: an object management space defined in said memory; an object processing module for processing said media object in accordance with a pattern definition list stored in said object management space; and a media object space defined in said memory for storing new media objects generated by said object processing module, wherein said pattern definition list includes a plurality of action statements each defining a script program to be executed, in association with a pattern formula designating attributes of each media object, and said object processing module selects a script program corresponding to said media object based on a pattern formula indicated by said pattern definition list and executes media processing in accordance with the script program, thereby to generate a new media object having different attributes, repeats recursive media processing on the generated media objects as new input media objects in accordance with said pattern definition list, and selectively outputs a media object having an attribute pre-designated in said pattern definition list to said media object space and said display unit.
