Abstract: An apparatus of encoding an image and an apparatus of decoding an image are provided to guarantee a desired compression rate through entropy encoding. A prediction encoder(410) produces residual data about an input image by performing time-space prediction encoding. A converter(430) produces a conversion coefficient value by conversion of the residue data. An entropy encoder(470) encodes pattern information of each group generated according to a quantized conversion coefficient value. The entropy encoder encodes a level of the quantized conversion coefficient value corresponding to pattern information of each layer group.

Abstract: An apparatus of encoding an image and an apparatus of decoding an image are provided to adaptively determine a scanning order based on importance of each coefficient value according to a location, thereby increasing entropy encoding efficiency of the conversion coefficient value. A scanning unit(110) scans a conversion coefficient value of a conversion block according to a scanning order. An important coefficient inspecting unit(130) inspects importance from conversion coefficient values of one dimensional array. An importance correction unit(150) corrects a weighted value according to each location of the conversion block by the importance information. A scanning order determining unit(170) determines a scanning order from a large weighted value to a small weighted value based on the corrected weighted value.

Abstract: An apparatus and a method for encoding and decoding images are provided to predict residual colors of the R and B components of RGB signals of an image from a residue color sample of the G component of the RGB signals to efficiently reduce correlation among the R, G and B components and encode the image. An apparatus for encoding an image includes a residue generator(10) for generating first residues corresponding to color component differences between a current image and a predicted image, and a unit for space-converting and quantizing the first residue of a first color component and performing inverse quantization and inverse space conversion on the quantized first residue of the first color component to reconstitute the first residue of the first color component. The apparatus further includes a residue prediction unit(16) for predicting second residues with respect to the first residues of other color components by using the reconstituted first residue of the first color component, and an encoder(13) for encoding the first residue of the first color component and the second residues of the other color components.
