Abstract

The invention relates to a multi-window display device and a multi-window display method. The multi-window display device comprises multiple input image processing modules used for generating image windows and an output synthesis module used for synthesizing multiple image windows processed by the input image processing modules into an output image. Each input image processing module comprises an input signal acquisition module, an image scaling processing module and a frame synchronization processing module, the input signal acquisition module is used for receiving input image signals and converting the received image signals into digital parallel signals, the image scaling processing unit is used for scaling the size of video signals output by the input signal acquisition unit into resolution required by the image windows, and the frame synchronization processing module is used for determining the positions of the scaled image windows and outputting the image windows to the output synthesis module. By the multi-window display method and the multi-window display device, number of buses required for direct superposition of single module images is reduced, and hardware implementation is facilitated greatly.

Description

technical field [0001] The present invention relates to a display device and a display method for displaying multiple image windows on one display, and further relates to a display device and a display method for displaying multiple image windows on multiple displays. Background technique [0002] With the development of display technology, the size of display devices is getting larger and the resolution is getting higher and higher. This enables multiple image windows to be displayed on one monitor, making it possible to monitor a large number of image signals with a small number of monitors. Such a multi-window display device in a display is widely used in the monitoring of television signals and monitoring signals. With the improvement of the performance of the display device, the increase of the number of images to be monitored and the improvement of the input image resolution, the number of image windows to be displayed on a display device is also increasing, and the r...
