Abstract
A method for encoding image signal, according to the present invention, can: encode a partial block coefficient flag indicating whether a coefficient of a current partial block is a non-zero coefficient; encode a first flag indicating whether an absolute value of the coefficient is greater than 1, encode a second flag indicating whether the absolute value of the coefficient is greater than 2; encode the residual coefficients, which have not been encoded, on the basis of the first flag or the second flag in the current partial block; and encode a code for the coefficient of the current partial block.
