摘要： 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.

摘要： 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.

摘要： The present invention provides a method and device for adjusting resolution of a Head-Mounted Display (HMD) apparatus. Wherein, the method comprises the steps of: determining saliency information of display contents in multimedia information; adjusting, according to the saliency information, resolution corresponding to each display content in the multimedia information; and, displaying the resolution-adjusted multimedia information. In the present invention, by determining saliency information of display contents in multimedia information, the resolution corresponding to the display contents is adjusted, which enable the resolution of the display contents to be matched with the saliency of the display contents, and accordingly, the resolution-adjusted multimedia information is displayed without the need of displaying the complete multimedia information in a higher resolution and a higher frame rate. In this way, computation amount for a device is greatly reduced, so that requirement for device hardware is reduced and device cost is reduced, and displaying efficiency is improved whilst at the same time ensuring good displaying effect.
