Abstract

A motion evaluating device and method with optimized complication degree. Disclosed is a motion evaluating (ME) device and method using a motion vector (MV) fast searching algorithm, which can significantly reduce calculation amount by using the fast searching algorithm rather than a traditional global search algorithm, and which will allows the user to define the complexity level of the calculation. The MV fast search algorithm induces about 0.5 dB of image degradation at most, but can significantly reduce the calculation amount. As the calculation amount of the ME circuit can be adjusted by inputing the calculation complexity parameters, it make a pipeline arrangement taking a parallel approach to implement the texture coding in it, have a highest efficiency.

Description

technical field

[0001] The present invention generally relates to motion estimation (ME) devices and methods. More particularly, the present invention relates to an ME device and method using a fast search algorithm of a motion vector (MV), which can significantly reduce the amount of computation by utilizing the fast search algorithm instead of a conventional global search algorithm, and allows the user The level of computational complexity is set such that the ME apparatus and method can be readily used in various applications. Background technique

[0002] Motion Estimation (ME) techniques are used to achieve high compression efficiency by removing temporal redundancy in video. Video is compressed or encoded using ME technology with international standards such as Moving Picture Experts Group (MPEG), H.263, and the like.

[0003] Because the ME operation requires a lot of computation in the video compression process, it seriously affects the overall performance of the v...
