METHOD FOR ENCODING/DECODING IMAGE SIGNAL, AND DEVICE THEREFOR
This abstract first appeared for US patent application 20250071329 titled 'METHOD FOR ENCODING/DECODING IMAGE SIGNAL, AND DEVICE THEREFOR
Original Abstract Submitted
a method for decoding an image according to the present invention may comprise the steps of: deriving a residual coefficient of a current block; dequantizing the residual coefficient; deriving a common residual signal by performing inverse transform of the dequantized residual coefficient; and deriving a first residual signal of a first chroma component and a second residual signal of a second chroma component on the basis of the common residual signal.
