Abstract
An image encoding method includes generating symbols by performing transformation and quantization according to a transformation block, on a block that performs prediction according to a prediction mode; updating a probability index of a current sub block by using a probability index of a previous sub block among sub blocks included in the transformation block; determining a rate according to a bit length of the current sub block by using the probably index; determining a rate of the transformation block by using rates of the sub blocks; determining a distortion by using a difference between an original image and a reconstruction image according to transformation and quantization; and determining a rate-distortion (R-D) cost by using the distortion and the rate.
