Embodiment Construction

[0021] The specific implementation of the method and system for zooming the signal source of the display window of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] refer to figure 1 , figure 1 Shown is a flow chart of a signal source scaling method for a display window in an embodiment, including the following steps:

[0023] S10, acquiring window coordinate parameters of the display window, signal coordinate parameters of the signal source, and intersection coordinate parameters of each display unit in the display window and the display window;

[0024] The above window coordinate parameters of the display window may include window start coordinates, window width, window height and other parameters that can characterize the position and size of the display window on the spliced ​​display screen. Specifically, the above-mentioned spliced ​​display screen includes a plurality of display screens, and each display scr...

Abstract

The invention relates to a signal source zooming method and system for a display window. The signal source zooming method for the display window comprises the following steps of obtaining window coordinate parameters of the display window, signal coordinate parameters of a signal source, and intersection coordinate parameters of display units in the display window and the display window; accordingto the window coordinate parameters, the signal coordinate parameters and the intersection coordinate parameters, identifying intersection input data corresponding to the display units at the signalsource in the signal source; and according to a ratio of the signal coordinate parameters to the window coordinate parameters, performing zooming on the intersection input data. Related image parameters corresponding to the display units in the display window obtained after zooming can be seamlessly spliced, so that the problem of discontinuousness at a splicing seam between two adjacent display units is effectively avoided and the image display effect of the corresponding display window can be improved.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a method and system for scaling a signal source of a display window. Background technique [0002] Splicing display devices such as large-screen splicing walls are generally composed of several rows and columns of display screens, and several display windows including display units corresponding to multiple display screens can be opened in the large screen. The signal of the large-screen video wall display window is the acquisition card acquisition signal of the processor, which is controlled by the main control to the corresponding output card for processing and output. Each display window may span multiple display screens, but each output card is only responsible for processing the image data output on the output card, so that each output card cannot directly use the original input image data for scaling. The above scaling process needs to be The input image i...
