Abstract
In a method for generating image depth maps for image frames included in a video, an image processing device is configured to: acquire a full depth map of an nth image frame of the video; find a to-be-processed region of an (n+m)th image frame of the video, the to-be-processed region differing from a corresponding region of the nth image frame of the video; process the to-be-processed region of the (n+m)th image frame of the video for generating a partial depth map that corresponds to the to-be-processed region; and generate a full depth map of the (n+m)th image frame of the video by using the partial depth map to replace a part of the full depth map of the nth image frame of the video that corresponds in position to the partial depth map.
