Abstract

A method, an apparatus, and a non-transitory computer readable medium for performing 2D to 3D conversion are presented. A 2D input source is extracted into left and right 3D images. Motion vectors are calculated for the left and right 3D images. Frame rate conversion is performed on the left 3D image and the right 3D image, using the respective calculated motion vectors, to produce motion compensated left and right 3D images. The left and right 3D images and the motion compensated left and right 3D images are reordered for display.
