Abstract
An image encoding method includes: determining N P-frames from a sequence of images, N being a positive integer; for each P-frame, determining a source refreshing region in the P-frames, the source refreshing region being a portion less than a whole region of the P-frame; obtaining reconstructed images corresponding to the source refreshing regions by performing a first encoding on the source refreshing regions; obtaining updated P-frames by updating the source refreshing regions with the reconstructed images; and performing a second encoding on the updated P-frames.
