(54)Method, medium, and system compressing and/or reconstructing image information with low complexity


(57) A system, medium, and method compressing and/or restoring images. Such a data compression method may include selecting a mode from among a plurality of modes for compressing current data, according to predetermined criteria, and calculating a difference between the current data and reference data, according to the selected mode, and compressing the current data, or truncating a part of the current data and compressing the current data. Accordingly, it is possible to significantly lower the complexity of an image encoder/decoder system and exactly meet a picture-based CBR required by LCD DCC devices/systems.
