Abstract
A video encoder and a video decoder are configured to take the variations in the third-dimensional parts of video frames into consideration. The video encoder determines how to generate compressed data of a late video frame according to a three-dimensional difference between an early video frame and the late video frame, and the video encoder includes a decision circuit and an encoding circuit. The decision circuit generates a decision result according to the three-dimensional difference between the early video frame and the late video frame. The encoding circuit performs a three-dimensional compression process to the late video frame when the decision result indicates that the three-dimensional difference satisfies a predetermined condition, and the encoding circuit performs a routine compression process to the late video frame when the three-dimensional difference does not satisfy the predetermined condition.
