1. A decoding apparatus for image decoding, the decoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
obtain image information; and
generate a reconstructed picture based on the image information,
wherein the obtaining the image information comprises:
obtaining a flag representing whether one chroma quantization parameter table is applied or not; and
obtaining at least one chroma quantization parameter table based on the flag,
wherein the flag equal to 0 represents that a first chroma quantization parameter table for a Cb component, a second chroma quantization parameter table for a Cr component, and a third chroma quantization parameter table for a joint CbCr component are signaled.
