    Abstract: A motion estimation encoding/decoding apparatus and a method thereof are provided to reduce bits wasted due to the reflection of an amount of illumination change by compressing an amount of the illumination change using spatial closeness of illumination change occurrence areas. An illumination change compensating module(320) differentiates a pixel average value of a present block and a pixel average value of a reference block to perform illumination change compensation. A residual signal generator(330) generates a residual signal by differentiating the present block having been subject to the illumination change compensation the reference block having been subject to the illumination change corresponding to a motion vector. An illumination change predicting module(340) sets an illumination change amount of a neighboring block, which has been subject to the illumination change compensation, as the prediction value of the illumination change amount of the present block. The illumination change predicting module performs a DPCM(Differential Pulse Code Modulation) based on the illumination change amount of the present block and the prediction value of the illumination change amount.

    Abstract: PURPOSE: A method for adaptively estimating a motion vector in a multi-view image and a method thereof are provided to reduce a motion vector difference using only blocks related to a current frame among surrounding blocks, thereby increasing a compression rate. CONSTITUTION: A block detecting unit(110) detects only blocks, which refers to the same block as a block to which a current block temporally or spatially refers, among blocks adjacent to the current block. An adaptive estimating unit(140) calculates an estimation motion vector value based on the number of blocks and motion vectors of blocks which are detected in a temporal vector estimating unit or a spatial vector estimating unit.

    Abstract: A predictive coding/decoding apparatus and a method thereof using view-temporal reference picture buffers are provided to reduce the quantity of data of a single view encoder by effectively removing redundancy information between view points. A predictive coding apparatus includes a multi-view reference picture providing unit(340), a prediction unit(310), a transform and quantization unit(320), and an entropy encoder(330). The multi-view reference picture providing unit provides a reference picture for predictive encoding according to spatial-temporal GOP(Group Of Picture) information. The prediction unit predicts which part of the reference picture is referred by a picture to be currently coded and generates a vector. The transform and quantization unit obtains a differential signal between a prediction signal received from the prediction unit and a video signal to be currently coded, transforms and quantizes the differential signal, and compresses the signal. The entropy encoder encodes the quantized signal received from the transform and quantization unit and the vector provided by the prediction unit.
