Abstract
A method of depth map generation is disclosed. The method comprises the steps of: scaling down a video unit and a previous video unit to generate a reduced video unit and a reduced previous video unit; dividing the reduced video unit into N1 portions and a buffer into N2 storing units; performing a motion estimation for a target pixel of the reduced video unit to obtain a motion vector based on pixels in a preset search window established in the reduced previous video unit; assigning a depth value to the target pixel according to the motion vector; storing the target pixel in one of the N2 storing units sequentially; and, repeating the steps of performing, assigning and storing until all pixels of the reduced video unit are processed to obtain a motion depth map.
