Abstract

Various display control methods and apparatuses are provided. A method comprises: acquiring azimuth information of a lens relative to a display plane, determining a desired display area of a display content of the display plane in the display plane according to the azimuth information, and adjusting a display position of the display content on the display plane according to the desired display area. A complicated operation that the lens looks for and/or is aligned with the display content is simplified, and the probability of active discovery of the display content and the probability of capturing the display content displayed in the display plane by the lens are thereby increased.

First claim

8. The method of claim 1 , wherein the determining the desired display area in the display plane of the display content of the display plane according to the azimuth information comprises:
determining an intersection position between an optical axis of the lens and the display plane according to the azimuth information; and
determining the desired display area according to the intersection position.

9. The method of claim 1 , further comprising:
after the desired display area is determined, adjusting a scale of at least part of the display content according to the desired display area.

10. The method of claim 9 , wherein the adjusting the scale of at least the part of the display content according to the desired display area comprises:
in response to determining that a current display area of the display content is less than the desired display area, zooming in at least the part of the display content according to the desired display area.

11. The method of claim 1 , further comprising:
before the adjusting the display position of the display content on the display plane, receiving a shooting request for the display content.

12. The method of claim 1 , further comprising:
before the adjusting the display position of the display content on the display plane, receiving a display position adjustment request for the display content.

13. The method of claim 1 , further comprising:
before the adjusting the display position of the display content on the display plane, determining that the lens is within a view range of the display plane.
