ABSTRACT:
A video encoding method includes generating a primary error image by performing motion estimation and compensation on a current frame with reference to a previous frame, generating a secondary error image by performing motion estimation and compensation on the primary error image of the generated current frame with reference to an error image of the previous frame. The error image of the previous frame is obtained by performing motion estimation and motion compensation on the previous frame when the previous frame is encoded.
