Original Abstract Submitted
According to the disclosure of the present documents, a quantization parameter used in a scaling process of a quantized escape value in a palette mode may be derived on the basis of minimum quantization parameter information relating to a transform skip mode. Accordingly, the amount of data required to be signaled for video/image coding can be reduced and escape coding in a palette mode can be effectively performed.
