Abstract

The present invention relates to image processing, and more particularly, to a video coding/decoding method using a clipped motion vector and an apparatus thereof. An embodiment of the present invention relates to a method of decoding an image. The method includes clipping a motion vector of a reference picture in a predetermined dynamic range to generate a clipped motion vector, storing the clipped motion vector in a buffer, deriving a motion vector of a coding treeblock using the motion vector stored in the buffer, and performing inter prediction decoding process using the motion vector of the coding treeblock. According to the exemplary embodiment of the present invention, a size of a memory required for storing motion vectors may be reduced.

Claims (61)

1 . An image decoding apparatus comprising:

a reference picture buffer to store a reference picture; and

one or more processors to

calculate a scaling factor for a current block in a current picture based on a picture order count of the reference picture,

clip the scaling factor in a first predetermined range,

scale a motion vector of the reference picture based on the clipped scaling factor,

clip the scaled motion vector of the reference picture in a second predetermined range which is defined as a predetermined fixed value range,

obtain first motion vector resolution information from a sequence parameter set within a bitstream, wherein the first motion vector resolution information is about motion vector resolutions for all blocks referring to the sequence parameter set,

obtain second motion vector resolution information, from a picture header of a current picture within a bitstream, specifying whether motion vector resolutions used for all blocks in the current picture are only integer pixel resolutions,

modify the clipped scaled motion vector of the reference picture based on a motion vector resolution derived by the first motion vector resolution information and second motion vector resolution information,

generate a prediction block based on the reference picture and the modified motion vector of the reference picture, and

wherein the motion vector of the reference picture is determined as a motion vector of a collocated block in the reference picture, and

wherein determining the motion vector of the collocated block by the one or more processors comprises:

calculating a first position corresponding to a right-bottom position representing a position displaced from an upper-left position of the current block in the current picture by the current block's height and width,
