Abstract
An image coding method includes obtaining image format information, determining a subsampling method for a luminance signal, storing the subsampling method in a memory, obtaining the subsampling method from the memory, performing subsampling on a luminance signal of a surrounding pixel, calculating a parameter of the linear model using (i) the luminance signal that is subsampled and (ii) chrominance of the surrounding pixel, performing subsampling on the luminance signal of the current block to be coded, and calculating prediction chrominance of the current block to be coded using (i) the parameter of the linear model and (ii) the luminance signal that is subsampled.
