Depth adjustment of ROI using scalable multiplexing in 3D display

In this paper, we presents a depth adjustment technique that controls depth of region of interest using scalable multiplexing in 3D display. Autostereoscopic displays offer different 3D images depending on the viewing direction. In order to display various viewpoint images on the autostereoscopic display at the same time, we usually divide the space of display panel spatially. This is called spatial multiplexing. However, this spatial multiplexing causes degradation of each viewpoint image resolution. Each viewpoint source is resized with the ratio of the inverse proportion to the number of view due to limited resolution of 3D display. When the images are downscaled with a certain ratio and, the downscaling ratio of the object of interest is bigger than that of the others, the object of interest is enlarged more than the other region without any loss. Moreover, enlarged object region covers the other regions belong to the background of image. In this case, the covered area can offer enough space to make the object that has binocular disparity without any interpolation of holes. It can also control the object´s depth in the 3D scene.
