Abstract
The image encoding and decoding method and apparatus based on a periodicity on phase signal are disclosed. One embodiment on an encoding an image, the method comprising: generating a prediction signal for an input signal, calculating an initial residual signal, which is a difference value between the input signal and the prediction signal, generating a transformed residual signal by transforming a value of the initial residual signal to have a size value within a preset range, and encoding the transformed residual signal, wherein the transformed residual signal is generated based on a period of a signal, wherein the preset range is a range of the period of the signal.
