Abstract: 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.
