Method and apparatus for encoding/decoding image

Abstract

A method for decoding an image, according to the present invention, comprises the steps of: receiving image information that corresponds to a block to be decoded; performing entropy-decoding with respect to the image information that is received; deciding a transform skip mode of the block to be decoded from a plurality of transform skip mode candidates, based on the image information that is entropy-decoded; and reverse-transforming the block to be decoded based on the transform skip mode that is decided.

Description

[0001] This application is a branch of a patent application with an international filing date of October 17, 2012, an international application number of PCT / KR2012 / 008482, a national application number of 201280061789.0, and an invention title of "Method and Device for Image Encoding / Decoding" case application. technical field

[0002] The present invention relates to image processing, and more particularly, to a transformation method and a transformation apparatus. Background technique

[0003] Recently, demands for high-resolution and high-quality videos such as high-definition (HD, high-definition) and ultra-high-definition (UHD, ultrahigh-definition) videos have gradually increased.

[0004] In order to provide video with higher resolution and higher quality, the amount of video data increases. Therefore, the cost of providing high-quality video transmission and storing video data rises compared to conventional video data processing methods. In order to solve these pr...

Embodiment Construction

[0050] Although the elements illustrated in the drawings are independently shown to represent different unique functions in the video encoding device / decoding device, such a configuration does not suggest that each element is constructed by a separate hardware component or software component. That is, the elements are independently arranged for convenience of description, wherein at least two elements may be combined into a single element, or a single element may be divided into a plurality of elements to perform functions. It should be noted that embodiments in which some elements are integrated into one combined element and / or one element is divided into a plurality of individual elements are included in the scope of the present invention without departing from the essence of the present invention.

[0051] Hereinafter, exemplary embodiments of the invention will be described in detail with reference to the accompanying drawings. Throughout, the same reference numerals refer...
