METHOD AND APPARATUS FOR IMAGE ENCODING/DECODING

摘要

An image encoding/decoding method and a device are disclosed. The image decoding method includes a step of drawing a scale factor for a current block according to whether the current block is a conversion skip block and a step of performing scaling for the current block based on the scale factor. The scale factor for the current block is derived based on a position of a conversion coefficient in the current block. The conversion skip block is a block to which the conversion of the current block is not applied and specialized based on information indicating reverse conversion to the current block.
