摘要： Method for searching for a small moving object is used to insert an inserting image frame between two adjacent image frames. An inserting region in the inserting image frame is selected. Multiple preset extending directions passing through the inserting region are selected. The extending directions respectively intersect the two image frames simultaneously to analyze whether the extending directions satisfy a condition of movement of the same image object, and obtain at least one motion vector (MV) corresponding to the extending direction. A globe MV between the first image frame and the second image frame is obtained. It is compared whether a motion-vector difference between the at least one MV and the globe MV is smaller than a setting value, and then first local-region image data and second local-region image data corresponding to the MV are used for compensation to produce an inserting image for the inserted region about background.

摘要： A method for searching small moving object is used to insert an inserting image frame between adjacent two image frames. An inserting region is selected in the inserting image frame. Multiple extending directions passing through the inserting region are selected. Each of the extending directions extends and intersects with the two image frames to analyze out which one of the extending directions satisfies the condition of movement by the same object, and obtain at least one motion vector corresponding to the extending direction. A globe motion vector between the two image frames is obtained. A motion-vector difference between the at least one motion vector and the globe motion vector is compared to judge whether greater than a setting value. If the motion vector difference is greater than the setting value then the first local-region image data and the second local-region image data are treated as a small moving object.

摘要： An image processing circuit and an image processing method are disclosed. The image processing circuit comprises a block matching unit, a multiplexer, an arbiter, and a motion compensation circuit. The block matching unit calculates an alternating current (AC) sum of absolute difference (SAD) and a direct current (DC) sum of absolute difference (SAD) according to a current block in a current image and a reference block in a reference image. The arbiter controls the multiplexer selectively to output the AC SAD or the DC SAD according to an arbitration rule related to a scene characteristic of the current image. The motion compensation circuit executes motion compensation according to the AC SAD or the DC SAD outputted by the multiplexer.
