Abstract: A picture prediction method includes: determining motion vectors of W control points in a current picture block; obtaining motion vectors of P pixel units of the current picture block by using a motion model and the motion vectors of the W control points, where precision of the determined motion vectors of the W control points is 1/n of pixel precision, precision of the motion vector of each of the P pixel units is 1/N of the pixel precision, the motion vector of each of the P pixel units is used to determine a corresponding reference pixel unit in a reference picture of a corresponding pixel unit; and performing interpolation filtering on a pixel of the corresponding reference pixel unit by using an interpolation filter with a phase of Q, to obtain a predicted pixel value of each of the P pixel units.

Abstract: A keyboard and an electronic device are provided. The keyboard includes a button switch, a keyboard frame, and a mechanical part. The keyboard frame includes a transverse frame and a longitudinal frame. The transverse frame extends in a row direction and is continuously disposed. The longitudinal frame extends in a column direction and is connected between two adjacent transverse frames. A plurality of longitudinal frames are arranged in a staggered manner in the column direction. The mechanical part includes a transverse support rib and a longitudinal support rib. On a side that is of the keyboard frame and that is connected to the mechanical part, the longitudinal frame protrudes relative to the transverse frame, the longitudinal frame abuts and is attached to the transverse support rib, and an adhesive-accommodating gap for accommodating adhesive is formed between the transverse frame and the transverse support rib.
