| 摘要 | An apparatus has a motion vector estimation module to perform motion vector estimation on a current frame and on a previous frame of image data to produce a current phase and a previous phase, a motion vector generation module to generate motion vector fields for the current and previous phases, and a motion vector interpolation module to find interpolated motion vectors for an interpolated phase that have minimal differences between motion vectors in the current and previous motion vector fields and to product interpolated motion vectors. | ||

| 主权项 | 1. A method of providing motion vectors for an interpolated frame of image data, comprising: performing motion vector estimation on a current frame and on a previous frame of image data producing a current phase 1 pointing from the current frame to the previous frame and a previous phase 0 pointing from the previous frame to the current frame; generating at least two motion vector fields, one for the current phase and one for the previous phases; and finding interpolated motion vectors for an interpolated phase that have minimal differences between motion vectors in the current and previous motion vector fields. | ||
