The present invention discloses a system for displaying a moving image, which selectively uses at least a part of a moving image frame in a plurality of moving image frames as the content of the background image data or the window through the graphical user interface. In order to make the description of the present invention more detailed and complete, reference is made to the following description in conjunction with the drawings of Figures 1 through 4.

Referring to Figure 1, a block diagram of a dynamic image system 100 is shown in accordance with an embodiment of the present invention. For example, the display motion picture system 100 can be a personal computer, a notebook computer, a personal digital assistant, a mobile phone, or a mobile video device.

Hereinafter, the present invention will be described by taking a video computer 100 as an example of a personal computer equipped with a WINDOWS XP operating system. The display dynamic image system 100 has a graphical user interface (GUI), and the graphical user interface has a background (also referred to as a desktop), and those skilled in the art can understand the display dynamic image system 100 according to the WINDOWS XP operating system. The graphical user interface and background/desktop are not mentioned here.

System 100 includes a motion image generator 102, a background module 104, and a control unit 106. The dynamic image generator 102, the background module 104, and the control unit 106 can be independent integrated circuits, or integrated into a single integrated circuit, or can be implemented by using a software, which is to be covered by the present invention. Within the scope. Preferably, the control unit 106 is a central processing unit, such as a central processing unit (CPU) produced by Intel Corporation, and the dynamic image generator 102 and the background module 104 are implemented by using a software. The medium motion picture generator 102 is a motion picture codec (coder/decoder) external to the Windows operating system, such as an MPEG motion picture codec, and the background module 104 is integrated into the Windows operating system. Among them.

For example, the motion picture generator 102 can generate a plurality of motion picture frames a according to an MPEG image file. The MPEG image files can be pre-stored in a storage device (not shown) of the system 100, such as a hard disk. The background module 104 sets the background based on the background image data b. The background image data b can be a picture file, or when the control unit 106 generates the control signal c, and the background module 104 controls the signal c, at least a part of the dynamic image frame of the plurality of motion picture frames a as the background image data b. . Preferably, the background module 104 includes a memory 112, such as DRAM, SRAM, and Flash Memory, for storing background image data b. The format of the background image data b may be a bitmap signal (BMP), a graphics exchange format signal (GIF) or a lossy compression map signal (JPG). Preferably, the motion picture generator 102 sequentially generates a plurality of motion picture frames a according to the MPEG image file, and the background module 104 controls the signal c to use the plurality of motion picture frames a as the background image in the same order. The data b is stored in the memory 112, and then the stored background image data b is sequentially played back at the background to present a dynamic image. The memory 112 can store only a single moving image frame, or can store multiple moving image frames at a time. Unlike the full screen playback mode of a typical image file, when the image file is played back in the background, it does not cover other windows and icons in front of the background, and the user can still perform other functions in other windows. jobs.

The invention is further illustrated by the Microsoft Windows operating system. The user selects to display the motion image on the background/desktop or the window through the graphical user interface.

Preferably, the adjusted dynamic image frame is combined with the original background image data in the existing memory, and the combined image data is stored in the memory again, so that the original background is displayed on the background. In addition to the image data, the adjusted motion picture frame is also displayed. That is, the motion picture frame does not cover other windows and icons in front of the background/desktop, and the user can still perform other work in other windows.

If the user decides to display the motion picture frame in the background, he can call the function in the windows operation system, such as GetDesktopWindow() or FindWindow(), to store the original background image data of the original background in other memory blocks or Storage media. Then, the plurality of motion picture frames generated by the motion picture generator are used to adjust the format of the motion picture frame to the background image data of the background display format through the control unit, and write the memory for placing the background image data. In addition, call the windows operating system again. The function in , for example, SystemParametersInfo(), displays the background image data stored in the memory in the background in the operating system.

The system 100 for displaying a dynamic image further includes a color space converting unit 108 for converting each pixel in the moving image frame a from the first color space to the second color space. For example, each pixel in the plurality of moving image frames a Located in the YUY2 color space, the color space conversion unit 108 converts each pixel of the moving image frame a from the YUY2 color space to the RGB32 color space, that is, converts the dynamic image frame a of the YUY2 format into a dynamic image frame of the RGB32 format. ', and the dynamic image frame a' of the RGB32 format is supplied to the background module 104 as the background image data b. In this embodiment, the color space conversion unit 108 can be an independent integrated circuit, or can be implemented by using a software.

In addition, the system 100 for displaying a moving image further includes an adjusting unit 110 for adjusting the resolution, color, brightness, or frame rate of the moving image frame a to be converted into a moving image frame a". Generally, when utilizing When the background image is displayed, the quality of the displayed image is low. For example, the frame rate of the motion picture frame a is 30 frames per second, and the adjustment unit 110 sets a plurality of motion picture frames a (30 fps). The frame rate is adjusted to (for example, 24 fps or 15 fps), that is, the 30 fps motion picture frame a is converted into a lower frame rate motion picture frame a' for background display. In this embodiment, the adjustment unit 110 can be an independent integrated circuit, or can be implemented by means of software.
