1. A display device comprising: a screen; and at least one processor configured to obtain a sequence of image frames constituting an initial image from an external image source and generate a control signal based on the obtained sequence of image frames; a display configured to generate, based on the control signal, a spatial light distribution pattern corresponding to the sequence of image frames; a spatial-to-angular distribution transformer configured to transform the spatial light distribution pattern to an angular light distribution pattern and generate at least two parallax images associated with the sequence of image frames based on the angular light distribution pattern; and an image relay and scanner configured to magnify the at least two parallax images and generate a fused image, the fused image being a magnified version of the initial based on the at least two magnified parallax images; wherein the at least one processor is further configured to control the screen to display the fused image.
