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 video encoding/decoding apparatus and method for color images include a first motion prediction unit that generates a first prediction residue image of an input image on a basis of a first motion prediction result of the input image. An image information detection unit sets a predetermined color component of an R-G-B image to a reference color component and determines whether the input image is a Y-Cb-Cr image or an R-G-B image and whether a color component is the reference color component. A second motion prediction unit performs motion prediction for the first prediction residue image and generates a second prediction residue image if the input image is the R-G-B image and the color component of the input image is not the reference color component.

摘要： An encoding method may comprise obtaining a residue corresponding to a difference between the original image and a prediction image with respect to each component of the original image, encoding the residue of a predetermined component of the original image, restoring the encoded residue of the predetermined component and transforming the restored residue into a predetermined value including the restored residue value, and encoding prediction residues corresponding to differences between each of residues of components of the original image, which are not encoded, and the residue, which is restored and transformed into the predetermined value. Since prediction residues are encoded and decoded using correlations between residues of image components and image components, data amount is highly reduced. Also, since there is no quality loss in a picture generated by directly encoding an R-G-B image without transforming it into a Y-Cr-Cb image, high quality image information is obtained.
摘要翻译：编码方法可以包括对原始图像和原始图像的每个分量之间的原始图像和预测图像之间的差异相对应的残差，对原始图像的预定分量的残差进行编码，恢复预定分量的编码残差将恢复的残留变换为包括恢复的残差值的预定值，以及编码对应于未被编码的原始图像的分量残差中的每个残差之间的差异的预测残差和被恢复并变换为预定的残差的残差值。由于使用图像分量和图像分量的残差之间的相关性对预测残差进行编码和解码，所以数据量大大降低。此外，由于通过直接编码R-G-B图像而不将其变换为Y-Cr-Cb图像而产生的图像中没有质量损失，因此获得高质量的图像信息。
