Abstract
A motion estimation device includes a memory to store a reference image, a bus connected to the memory; and a motion estimator to control a size of data of a reference image block depending on an available bandwidth of the bus when extracting at least one reference image block for motion estimation from the reference image through the bus.
Claims19
A system on chip (SoC) comprising:
- a memory configured to store image data;
- and
- a motion estimator configured to extract one or more image blocks of the image data in the memory and to adjust at least one of a size and a quantity of the image data extracted based on an available bandwidth of the motion estimator, the motion estimator including a cache memory configured to store the extracted one or more image blocks of the image data.
A motion estimator comprising:
- a cache memory configured to extract one or more reference image blocks of a reference image;
- a reference bandwidth setting unit configured to determine a reference bandwidth based on an available bandwidth;
- and
- a motion estimation unit configured to determine a number of reference image blocks of the reference image that are to be extracted depending on the reference bandwidth, and to perform a motion estimation using the extracted one or more reference image blocks of the reference image.
