DIGITAL PROCESSING METHOD OF APPEARANCE EXPRESSION TRANSFORM DATA

摘要

PURPOSE: A digital processing method of an appearance expression transform data is provided to reduce an undesired error in inverse transform data which is generated by a clipping or a rounding by correcting an error at a transform domain after forward transforming data processed at a real domain. CONSTITUTION: In a method of processing transform data for expressing an appearance, the transform data is inverse transformed into a real domain to form high-precis ion numbers(120). The high-precis ion numbers are transformed into an integer, and the integer is clipped to form initial converted data (140). The transformed data is subtracted from the high-precis ion numbers to form high-precis ion differences(1100). The initial converted data is operated in order to generate an effect and to form processed converted data (310). The high-precis ion differences are added to the processed converted data to form processed high-precis ion numbers(1130).
