The present invention discloses an image predictive coding method and an encoder, to prevent an error occurring in a Tile from spreading to an entire frame of image. In the present invention, during a process of encoding an LCU in a Tile of a current frame, a Tile of the current frame is determined first, in which the to-be-predictive-coded LCU or a PU is located, then, a Tile of a reference frame is determined in the reference frame of the current frame, where a position of the Tile of the reference frame is the same as a position of the Tile of the current frame in the current frame, when a PU of the LCU is predicted, a reference pixel is selected from the determined Tile of the reference frame, and when a PMV of the PU included in the LCU is determined, the PMV of the PU is selected from the determined Tile of the reference frame, which can prevent an error occurring in a Tile from spreading to an entire frame of image, thereby improving accuracy of image coding. |
