Abstract
The present invention provides a motion estimation circuit and an operating method thereof. The motion estimation circuit includes processing elements PE(−n≦m≦n, n represents a search range), data latches FF(−n<k≦n) and selection circuits MUX(−1≦h≦1). The processing element receives a current block data and the corresponded block data in a search window and performs a comparison operation on the two block data. The output-end of FFis coupled to an input-end of FFand a first input-end of PE. The output-end of MUXis coupled to a second input-end of PE. Wherein, each 4×4-pixel sub block of the current block is input into PEand FF, the left sector of the sub-search-window SW' is input into the second input-ends of PE˜PEand the first input-end of MUX, and the right sector of the sub-search-window SW′ is input into the second input-ends of PE˜PEand MUX.
