Abstract: A 3D-image providing device comprises: an index selection unit for selecting at least one index frame set from 3D-image data including plural frame sets; and a thumbnail generation unit for obtaining left and right images for the selected index frame set and generating a thumbnail frame set based on the obtained left and right images, wherein the frames included in the thumbnail frame set satisfy conditions that the sizes and resolution thereof are respectively small and low compared to the frames included in the index frame set. Accordingly, the 3D-image providing device generates 3D-thumbnails from the left and right images of the 3D-image data to provide 3D images considered when moving to a user-desirable reproduction time point. Also, the 3D-image supply device merges the 3D-thumbnails with 3D-broadcasting images or 3D-contents and displays the merged image. Consequently, the image providing device minimizes viewer confusion when perceiving 3D-images and increases user satisfaction.
