1. An image encoding method by an encoding apparatus, comprising:
deriving prediction samples for a current picture;
generating a reconstructed picture based on the prediction samples;
applying an in-loop filtering process to the reconstructed picture;
generating prediction information for a prediction process;
generating offset information for a sample adaptive offset (SAO) process; and
encoding image information including the prediction information and the offset information,
wherein applying the in-loop filtering process includes applying a deblocking filtering process to the reconstructed picture, and applying the SAO process to a sample in the reconstructed picture on which the deblocking filtering process is completed,
wherein the offset information includes offset type information indicating a SAO type applied to the sample, and
wherein based on the offset type information indicating that a band offset type is applied to the sample, the offset information includes explicit band information indicating one of 32 bands as a starting band of a band group consisting of n bands, and an offset corresponding to a band among the n bands is applied to the sample, wherein n is an integer.
