1. A decoding apparatus for an image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
parse a flag related to weighted prediction from a bitstream;
parse a prediction weighted table syntax from the bitstream based on the flag;
generate prediction samples by performing weighted prediction on a current block in a current picture based on the prediction weighted table syntax; and
generate reconstructed samples for the current block based on the prediction samples,
wherein the prediction weighted table syntax is parsed from a picture header of the bitstream based on a value of the flag, and
wherein the picture header includes information which applies to all slices in a picture related to the picture header.
