In addition to the large-screen display device of the existing computer, another type of device that can display a large display area should be a projector. At present, the selling price of the projector is becoming cheaper and more popular. The popularity rate has been significantly improved in recent years; however, most of the existing projectors are enhanced and improved in image projection quality (9) such as brightness. The integration and switching functions of multiple image sources are still quite lacking. It is the limit of authority. Although there are two or more groups of input image signal sources designed for special models, the price of such projectors is quite expensive and it is difficult to push them universally (about 2 million to 3 million). [New content] The withdrawal of the technical means allows only multiple image sources to be selected and cannot select multiple images and simultaneously display them on a single surface. This creation proposes a response to this shortcoming. The main purpose of the creation of the wound piece is to provide a signal source selection function, which is a video signal mixing device that can be integrated into the display device or is independent of the outside, and the system includes ·· The receiving unit can receive a plurality of image signal sources and support a plurality of different image formats; the defending J Dan image processing unit is connected to the output end of the foregoing cymbal to receive two sigma processing operations and i-composite image signals Like the signal source and executing the image communication M316452, the peripheral device connection interface is bidirectionally connected with the control and image processing unit for connection with peripheral devices, and the second image = output unit is connected to the control and image processing unit. The input::: outputs the aforementioned composite image signal to the display device; the input " face is connected to the input end of the control and image processing unit 2 for connection with an external computer* to receive an external control command. ^ By the above architecture 'this creation can allow to receive multiple or different formats of multiple image sources, and can be used to output a number of image sources as output, and the image can be used in a single display device. Synchronous output. The purpose of the silly and wide-ranging person is to provide a shadow-sharing device with a signal source selection function. When the creation is integrated into a display device (such as ud): fruit is: up! J such as a high-priced projector The multi-function switching and signal mixing show that the beacon or projector is converted into a device with high value and steam economy. The door value and the other purpose of the creation of Aben provide a signal source selection function. Refer to the “诡 mixing device, when the creation is presented as a separate product, then 2 display devices and projectors become signal switching, display and mixing; benefit, eliminating the repetitive investment of equipment. σ双【Embodiment】 The image signal mixing function with the signal source selection function of this creation is a separate product that can be integrated into the display device or independent of the outside:: Different environments, the following is only the core of the creation. ^ μ Refer to the first figure, which is the circuit block diagram of the creation.

The detailed structure of the circuit units and interfaces of the coordinates and the corresponding diagram of the system In order to re-/, force this, it is introduced in March. First, please refer to the second figure 7 M316452 = shown, for the control and image processing unit (20) circuit block diagram, package receipt: = 22 } 'It is connected to the first image of the image signal receiving wheel to receive a plurality of image signal sources.

Allows the user to choose one of the most image signals. The mouth and the moon refer to the second figure, which is the distance from the neighbors to the community = / circuit i to connect the interface (3 〇): block diagram, this embodiment uses at least - peripheral controller (31) The multiplexer switching circuit (3 2 ), as in this embodiment, uses a peripheral controller of the PS/2 M316452, and the multiplex switching circuit (32) can be used to connect different/monthly machines, keyboards, and sound playback devices (such as 8. Headphones and other peripherals. When the above command receiving interface (5 〇) # receives the control signal, it designates any peripheral device as the device for controlling the creation according to the control signal, or selects the output of any of the sound playback devices. Please refer to the figure in the fourth figure for the instruction to receive the internal 2 diagram of φ(5〇), which can include the wired connection interface or the wireless connection interface. For example, the wired connection interface can be a serial port of RS 232. Or Ethernet (^Ethernet) connection, and the wireless connection interface is added according to the requirements, it can be a radio frequency receiver or an infrared receiver, etc. Whether it is a wired or wireless connection interface, the system is created and externally Computer or remote user In addition, the external computer can use the finer control commands to operate the creation, so that the multi-image presentation screen has a more flexible and more humanized display mode. In the aspect of the shirt image output 70 (40), it also supports There are a variety of output formats, if it is a low voltage differential signal transmission (LVDS) format, this creation: can be directly integrated into the liquid crystal display M. Users can specify the aforementioned control according to the display to be connected. _ J Dan ~ like processing the image signal of the specification (2 0) should be output, 1 is output to the display by the image wheel-out unit (4 0) in a compatible format. "As shown in the fifth to seventh figures, In the actual application, the creation has a variety of image presentation modes for the user to select, for example, in the fifth figure: two independent non-overlapping image planes (61) (62), each image: face (6 1 ) ( 6 2 ) can be adjusted to their respective sizes, and two (61) (62) can also occupy the left and right sides of the screen to form two M316452 full-window sides, which are convenient for comparing two windows as above. #固的贝枓 or present two large data, and brother The embodiment of the six figures allows the two search τ~image planes (6 1 ) ( 6 2) to overlap each other without affecting each other. In the two scent s areas, the upper image frame (6 1 ) is assumed to be i Image; in addition to h, there is also a sub-mother face as shown in Figure 7, where the child-like face (6 1) is on the mother image (6 2 ) , the cover of the seedlings #丹佥二^ Reproduce the original image of the mother's face, 'Valley and fully present its own image signal. • In terms of application areas, this creation is not only suitable for multi-person workplaces such as corporate companies, even for ordinary individuals. For example, in the workplace γ is used with a projector, when there are multiple images at the same time in a single table γ%% (inter-report, multi-party video conferencing, remote control, etc.), through the image mixing function of the original 2, the complex image signals can be integrated into a single composite shadow=signal to be input to the projector, making a wide range The projected image can display multiple images and use the display area more effectively. On the other hand, in the individual home, the existing TV, LCD, etc. can be used as a playback tool. After the signal source of the computer or video playback device (D v 13 ) is properly selected and mixed, the composite image can be viewed directly through the tool.
