A method for encoding an image having color components of each image pixel represented by a value of a high dynamic range, the method comprising: decomposing the image into a plurality of image blocks; separating, from the high dynamic range value of each pixel, color information and intensity information of the pixels in said image blocks; and compressing the color information of the pixels in said image blocks and the intensity information of the pixels in said image blocks independently of each other to provide compressed image data.
