Three dimensional video scaler and controlling method for the same

PURPOSE: A 3D view synthesis and a control method for getting a clear image are provided to supply 3D image by using a deep image. CONSTITUTION: The first and second image scalers(110, 120) enlarges first 2D and second 2D images. A filter(130) filters the second 2D image by using the first 2D image. The filter clearly filters the first 2D image by using the second 2D image. One image among the first 2D image and the second 2D image is a depth image.
