Description
Technical field
The present invention relates on a display, show multiple image window display device and display packing, further also relate to the display device showing multiple image window on multiple display and display packing.
Background technology
Along with the development of display technique, the size of display device is increasing, and resolution is more come higher.This makes can show multiple image window on a display, thus makes a small amount of display supervise a large amount of picture signals to become possibility.In such a display, windows display equipment is widely applied in TV signal, the supervising of pilot signal.Along with display device performance raising, need to supervise the increase of amount of images and the raising of input image resolution, a display device need the image window number shown also get more and more, the requirement of the processing power to equipment brought thus also rapidly improves, and makes the complexity of equipment, realizes cost and power consumption also sharply increases.
Existing multi-window display method generally adopts the following two kinds technical scheme to realize.

Described input picture processing module 400 is preferably also provided with image de interlacing processing unit 303, be connected between described input signal collecting unit 302 and image scaling processing unit 304, for the interlaced video signal signal of form (as: 1080i, the 576i etc.) of input is converted to progressive video signal.Signal for progressive input does not carry out any process at this unit.
Image scaling processing unit 304, for the resolution scaled through vision signal line by line required to image window, this process may be reduce, and also may be to amplify.
Frame synchronization process unit 305, for determining the position of the image window after convergent-divergent, and outputs to described output synthesis module 330 by this image window, can by image being synthesized to together with sequential of each window to ensure exporting synthesis module 330.The clock signal of the image window needed for frame synchronization process unit 305 is provided by synchronization timing unit 340.
Synchronization timing unit 340, for described frame synchronization process unit 305 provides synchronous sequence signal.
Described image de interlacing processing unit 303, image scaling processing unit 304 and frame synchronization process unit 305 can adopt the VXP image processor etc. of special IC as SIGMADESIGN to realize, and also can realize with FPGA.
Described output synthesis module 330, the image after described 4 input picture processing modules 400 are processed according to window position and stack order, synthesize an output image and export.When adopting special IC, parallel TTL interface, LVDS interface, HDMI/DVI interface etc. that the signal interface channel between described 4 input picture processing modules 400 can adopt special IC to possess; When adopting FPGA to realize, the signal interface channel between described 4 input picture processing modules 400 can adopt parallel TTL interface, LVDS interface, high-speed figure serial line interface.
Correspondingly, multi-window display method of the present invention is:
Described input signal collecting unit 302 receives the vision signal of multiple video signal source, and by described image de interlacing processing unit 303, this vision signal is converted to progressive video signal, the resolution that the scaled of vision signal requires to image window by described image scaling processing unit 304, described frame synchronization process unit 305 first determines the position of the image window after convergent-divergent afterwards, again by gathering the synchronous sequence signal that described synchronization timing unit 340 provides, by the timing synchronization of the vision signal of each signal source, finally this image window is outputted to described output synthesis module 330.
Refer to Fig. 2, it will be understood by those skilled in the art that if constantly increase described input picture processing module 400, really can increase the number of window, but such cost bus bandwidth also needs corresponding constantly increase.In order to increase the window number that can show under the prerequisite not increasing bus bandwidth, preferably, multiple described input picture processing module 400 and one can be exported synthesis module 330 and form one-level cascade module, and windows display equipment of the present invention can comprise at least two-stage cascade module, and be connected to the cascade input collecting unit 321 between two-stage cascade module and the composograph cascaded-output unit 331 after each output synthesis module 330.
