Description
Technical Field
The present disclosure relates to the field of image display technologies, and in particular, to an image adjustment method and apparatus.
Background
The large spliced screen is a whole large screen formed by splicing a plurality of screens, the existing large spliced screen can realize the real-time playing of single or each collected picture, when each collected picture is displayed, each collected picture can be displayed on each physical screen respectively, and when one collected picture is displayed, one collected picture can be paved on the whole large screen.
When one collected picture is displayed on the whole large screen, the collected picture needs to be split according to the number of screens forming the large screen before display, and corresponding image blocks are sent to screens at corresponding positions for display, so that the relative position of each image block on the collected image corresponds to the relative position of the display screen in the whole large screen; when each collected picture is displayed on a screen, in order to achieve a better viewing effect, each collected picture is often required to be set to be displayed on a fixed screen, and the position of each collected picture cannot be changed.
In the two cases, the relative display position of the screen display image in the large screen is strict, and once the position is disordered, the viewing effect of the user is influenced. For example, when an acquired picture is displayed on a large screen, if the display positions of some image blocks are disordered, the display picture seen by the user is disordered on the whole; for another example, when each captured image is displayed at a fixed position, if a mistake occurs, although the captured image can be normally displayed, the viewing effect of the user may be affected by the change of the position. However, the conventional large screen often causes disorder of the display position of the large screen due to some abnormal conditions in use.
