Image coding method, apparatus and image processing apparatus. The image encoding method includes encoding each pixel in the image area to determine the palette mode or non palette mode; to determine the corresponding image encoding region of the color palette; the palette for each of the first part having a plurality of components, each of the second part is the luminance component of pixels corresponding to the determined index; the pattern of pixel palette; determine the encoding information corresponding to pixels with non palette mode; and the color palette, pixel index and encoding information bit stream encoding. Thus, it is possible to apply palette based coding to images in non 4:4:4 signal formats, and to further improve compression ratio and reduce bit cost of encoding.
