    Abstract: An encoding method, medium, and system encoding an image, with an image being encoded by generating a plurality of image slices as images of each color component of the image and encoding the image slices in parallel with each other and independently of each other. Accordingly, although an image to be encoded has a large number of color components, the image can be compressed promptly. In addition, a decoding method, medium, and system are also provided decoding an image, with a plurality of encoded image slices being included in a corresponding bitstream, which are images of each color component of the image to be restored, are decoded in parallel with each other and independently of each other so as to restore the image using the decoded image slices. Accordingly, although an image to be decoded has a large number of color components, the image can be restored promptly.

    Abstract translation: 编码图像的编码方法，媒体和系统，其中图像通过生成多个图像切片作为图像的每个颜色分量的图像并且彼此并行彼此独立地编码图像切片而被编码。 因此，虽然要编码的图像具有大量的颜色分量，但是可以迅速地压缩图像。 此外，解码方法，媒体和系统还提供了对图像进行解码，其中包括在对应比特流中的多个编码图像片段，其是要还原的图像的每个颜色分量的图像并行解码 彼此独立，以便使用解码图像片恢复图像。 因此，尽管要被解码的图像具有大量的颜色分量，但可以及时恢复图像。
