摘要： A method, medium, and system encoding and/or decoding a moving picture. The moving picture encoding method may include selecting a prediction mode that is optimal for the macro blocks, which correspond to each other, of the color components of a current image based on the characteristics of a predetermined image, generating a predicted image for the current image according to the selected prediction mode, and encoding a moving picture using the predicted image. An optimal prediction mode can be adaptively applied to the macro blocks, which correspond to each other, of the color components, thereby increasing the moving picture's encoding and decoding efficiencies.

摘要： A color image and video encoding and/or decoding apparatus, method, and medium using inter-color-component prediction in accordance with an encoding mode are provided. The encoding apparatus for encoding an original image including at least two color image components, includes: a residue generation unit, if the encoding mode is inter mode, generating a temporal residue by obtaining the difference of a current image and a prediction image obtained by estimating a motion in units of blocks between the current image and a previous image of each color component; a residue color prediction unit encoding the temporal residue of the residue generation unit, by performing residue inter-color-component prediction; an intra color prediction unit, if the encoding mode is intra mode, encoding the original image by performing inter-color-component prediction of the original image; and an entropy encoding unit generating a bitstream by entropy encoding the result value of the residue color prediction unit or the intra color prediction unit. According to the apparatus, method, and medium, a color image or video data can be directly compressed effectively without a conventional color transform process. Furthermore, by using the correlation of image components, redundant information between color components varying with respect to the encoding mode is removed so that the encoding efficiency can be enhanced.

摘要： A method and apparatus for encoding and decoding image data. The method of encoding image data includes spatially predicting pixel values of a one-dimensional block of an image using blocks spatially adjacent to the one-dimensional block or temporally predicting the pixel values of the one-dimensional block using a temporally previous frame; transforming and quantizing the pixel values of the one-dimensional block; and generating bit streams for a one-dimensional conversion block when the transformed and quantized one-dimensional block is defined as the one-dimensional conversion block. Therefore, since the method and apparatus encode and decode image data in one-dimensional block units, real-time encoding and decoding can be achieved. In addition, compression efficiency can be enhanced while minimizing visual degradation of image quality.
