Abstract: A method for synthesizing a multi-view image using two-dimensional disparities is disclosed. The method comprises the steps of: searching corresponding pixels with respect to respective pixels in a left image and a right image to draw two-dimensional disparities, and generating a two-dimensional disparity map, based on two-dimensional disparities of the respective corresponding pixels; and combining a warped left image obtained by moving the respective pixels in the left image with a warped right image obtained by moving the respective pixels in the right image, based on the two-dimensional disparity map, to generate at least one intermediate image. The two-dimensional disparities consist of horizontal disparities and vertical disparities. The warped left image is obtained by moving the respective pixels in the left image, based on the number of the intermediate images. The warped right image is obtained by moving the respective pixels in the right image, based on the number of the intermediate images.
