摘要
The present invention relates to an image information encoding and decoding method and a device for same. One embodiment of an image information encoding method according to the present invention, as an image information encoding method according to another embodiment of the present invention, includes the steps of: generating a restore block; applying a deblocking filter on the restore block; applying a Sample Adaptive Offset (SAO) on the restore block having the deblocking filter applied thereon; and transmitting information on the SAO application. During the applying of the SAO, the SAO is applied to chroma pixels, and during the transmitting of the information, in addition to information on whether the SAO is applied on the chroma pixels, at least one of area information, division information on the SAO coverage area, SAO type information, and SAO offset information is transmitted.

Referring to Table 15, when a direction (angle) of an edge is determined, a case in which the intensity of a current pixel (C) is less than the intensities of two neighboring pixels forming an edge or a case in which the intensity of the current pixel (C) is less than the intensity of one neighboring pixel are set to a single category (Category 1).
