Abstract
A movement detection circuit, a motion estimation circuit and associated movement detection method are provided. The movement detection circuit includes a candidate searching module including a first-frame and a second-frame candidate circuits, an object selection module including a first selection circuit, a second selection circuit, and a motion vector calculation circuit. The first-frame and the second-frame candidate circuits respectively locate a first and a second first-frame candidate positions in the first frame and locates a first and a second second-frame candidate positions in the second frame. The first-frame object selection circuit identifies one of the first and the second first-frame candidate positions as a first-frame object position, and the second-frame object selection circuit identifies one of the first and the second second-frame candidate positions as a second-frame object position. An object motion vector representing movement of an object based on the first-frame and the second-frame object positions is calculated.
