Abstract:
An image encoding method includes determining and encoding global parallax data which is probably correct parallax data in consideration of the Epipolar geometry constraint between a camera of a standard viewpoint, which is selected from the entire multi-viewpoint images, and images obtained by all the other viewpoints; generating base parallax data for each camera as a viewpoint other than the standard viewpoint, where the base parallax data is probably correct parallax data in consideration of the Epipolar geometry constraint between the image of the relevant camera and the images of all the other cameras based on the global parallax data and the camera parameters; determining and encoding correction parallax data used for correcting the base parallax data, so as to indicate parallax data between the image of the relevant camera and an already-encoded reference viewpoint image used for parallax compensation; and encoding the image of the relevant camera by using parallax data obtained by correcting the base parallax data by means of the correction parallax data.
