Abstract: A method for reducing a moire fringe includes calculating a moire fringe width for each of different angles between a microlens array and pixels of a display screen. The method includes determining, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.

Abstract: An image processing method and apparatus are provided. The image processing method may include determining whether stereoscopic objects that are included in an image pair and that correspond to each other are aligned on the same horizontal line. The method includes determining whether the image pair includes target objects having different geometric features from those of the stereoscopic objects if the stereoscopic objects are not aligned on the same horizontal line. The method includes performing image processing differently for the stereoscopic objects and for the target objects if the image pair includes the target objects.
