A multi-signal image window display control method and system

Abstract

The invention discloses a method and a system for controlling multi-signal image window display. The method for controlling is characterized in that different input signal sources are converted into standard digital signals; and the standard digital signals are subjected to brightness and contrast adjustment and are converted into signals with fixed frame rate, the signals with fixed frame rate are subjected to synchronous time sequence configuration, the configured signals with the fixed frame rate is subjected to zoom and reduction processing, and a control system is used for window opening control, window switching and lamination controlling. A plurality of signals are synchronously processed in real time, window layers which have arbitrary sizes and on arbitrary locations in a display screen can be arbitrarily switched and overlapped to display; the luminance difference between signal windows can be solved, and a brightness control module and a signal contrast control module of the signals are additionally arranged on all the signal windows, the uniform display of a plurality of window signal brightness, brightness increasing of a dark field and brightness reducing of a bright field of the same signal source are realized, the contrast of image signals is increased, and a display frame can display normally and clearly.

Description

technical field [0001] The invention belongs to the field of image signal display, in particular to a multi-signal image window display control method and system. Background technique [0002] The traditional way to input a signal source is to display it in full screen on the screen. With the development of technology, there are more and more types of image signals. The traditional method of displaying one signal in full screen is not only a waste of the screen, but also cannot meet the requirements of displaying multiple signals at the same time, which is not conducive to improving work efficiency and operational flexibility. [0003] Or display fixed signals in sub-areas on the screen. When multiple signals need to be displayed, multiple signal sources need to be superimposed one by one. At present, the overlay control of the signal window requires the use of Alpha Blending controllers, Color Key controllers, or control computers for overlaying, which requires more resour...

AI Technical Summary

Problems solved by technology

At present, the overlay control of the signal window requires the use of Alpha Blending controllers, Color Key controllers, or control computers for overlaying, which requires more resources in the system for processing, and the position of the display signal window is not flexible

In addition, when displaying multiple signal windows, due to different signal sources, different acquisition processing, and different environments, the brightness difference between the signal windows and the internal contrast of the signal itself are different. When displaying low-brightness signals, the picture appears dark and high The screen is brighter, the signal is blurred, and the layers are not clear when the brightness signal is used
