  • Patent number: 11636573
    Abstract: An image processing method includes: downsizing a current frame and a reference frame; dividing the down-sized current frame and the down-sized reference frame into multiple first current blocks and multiple first reference blocks, respectively; performing a first motion estimation to the first current blocks and the first reference blocks to generate multiple first motion vectors; dividing the current picture and the reference picture into multiple second current blocks and multiple second reference blocks, respectively; performing a second motion estimation to the second current blocks and the second reference blocks to generate multiple second motion vectors; and generating a compensated frame between the current frame and the reference frame according to the second motion vectors. The second motion estimation includes: performing a 3D recursive search for each second current block; and adjusting multiple estimation parameters in the 3D recursive search according to the first motion vector.

  • Patent number: 11310460
    Abstract: An image processing method includes: receiving first and second frames; generating multiple motion vectors based on the first and second frames, wherein one of the motion vectors corresponds to a first block of the first frame and a second block of the second frame; calculating a to-be-compensated position of a compensated block, a first motion vector between the compensated block and the first block, and a second motion vector between the compensated block and the second block; determining whether a sum of the to-be-compensated position, a compensation value, and the first motion vector or the second motion vector exceeds a target range in order to set a blending coefficient; modifying first data of the first block or second data of the second block based on the blending coefficient; and generating interpolated data based on the modified first data or the modified second data.

  • Patent number: 9538051
    Abstract: A device and method using an overdrive function to do smoothing processing of video data including a frame sequence AABB or AABBB is disclosed in the present invention. The device includes a video information generator and an over drive circuit. The video information generator detects a plurality of continuous frames wherein the continuous frames include a current frame and a previous frame. When a second value of the current frame is different from a first value of the previous frame having the same position as that of the second value, the video information generator generates first video information; When the second value of the current frame is the same as the first value of the previous frame having the same position as that of the second value, the video information generator generates second video information.
