Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for personalizing the startup screen of a projector, and in particular, to a projector that is powered on by a foreign image file instead of the original startup screen.化 方法。 Methods. [Prior art] If the startup screen of the projector can be personalized, it can increase the added value of the projector. However, it is usually necessary to change the startup day and time, which needs to be modified by the developer and waste developer when compiling the firmware. In this case, it ’s difficult to modify the splash screen for a small number of customers, such as individuals or companies. Another current approach is to capture the projected image as an opening day to achieve a personalized effect. However, because the built-in memory of the projector is insufficient, and the image data cannot be captured in batches, only the daytime surface with a resolution of 640x480 can be captured. If the daytime resolution is higher, such as 800x600 or 1024x768, you must use The image magnification operation is generated, and the result is easily distorted. And only the projected image can be used as the startup screen, there is no other source. Therefore, we need a better method to solve the problems of the previous technology, so that the resolution of the daylight surface of the personalized startup is higher, the daylight quality is clearer, and the sources are more diverse. [Summary of the invention] The purpose of the present invention is to provide a kind of personalization of the projector when it is turned on. The advantage is that the personalized picture can reach the resolution of the south that is allowed by the projector, without distortion and without distortion. . Moreover, external 123 5 devices can be used to take pictures as the start-up day, so that the source is more diversified. ^ In order to achieve the above and other objectives, the present invention proposes a method for turning on a projector and personalizing it. The main steps include: connecting-the projector and-an external device. Then, in batch processing mode, read a picture file from an external device, temporarily store the picture file in a memory buffer, and then write it into the built-in flash memory of the projector, and replace the projector with the picture file. The original opening. Suffering from the above-mentioned personalization method of the projector when it is turned on, since it replaces the external device that is turned on, the source is more cost-effective than capturing the projection image of the prior art. In addition, according to the present invention, the image slot is transmitted in a batch mode. The size of this memory buffer does not limit the size of the image file. The image file can reach the highest resolution allowed by the projector, that is, the boot screen is not enlarged by the image. Operation without distortion. In order to make the above and other objects, features, and advantages of the present invention more obvious, it will be described below with reference to a preferred embodiment and the accompanying drawings. — [Embodiment] The following describes an embodiment of a method for personalizing a projector surface according to the present invention. FIG. 1 illustrates the concept of this embodiment. Projector (pr0ject0r) 101 can use built-in card reader 102, or a universal serial bus (universai bus (USB for short), USB), RS232, and internal bi-directional communication bus (mternal bi-directional c〇mmunicati〇n , Referred to as various transmission media such as 12o, from the perspective of external devices, replacing the original doc / 006 boot screen. The external device shown in Figure 1 has a large number of storage devices, memory card 104, and personal computer 1〇 6. Among them, the memory card 104 is connected to the projector 101 through the card reader 102, and the picture stored in the memory card 104 is from the digital camera 105. In fact, the storage content of the memory card 104 can come from various supported memory cards. 'External devices' and external devices can also contain more types. In this embodiment, the user changes the startup daytime surface in the personalization mode. To enter the personalization mode, the onscreen displa- y (referred to as OSD for short), enter the preset password to reserve the personalization mode at the next boot, then reboot, and then enter the personalization mode with the preset key combination. Figure 2 The password input in this embodiment is shown. Of course, the process of entering the personalization mode can be adjusted or simplified as needed, such as omitting the step of entering a password. As for the detailed flow of this embodiment, please refer to FIG. 3. First, the user Step 302 enters the above-mentioned preset password, and then restarts the projector in step 304. At this time, the original startup screen is still displayed. Next, in a period of time after the startup, step 306 will check whether the user presses After pressing the above key combination, if it is, the projector enters the personalized mode in step 308 and waits for the connection of the external device. If the user does not press the above key combination for a period of time, the projector enters the normal startup procedure, The method flow of this embodiment also ends accordingly. After entering the personalization mode, the user can press the key combination at step 31 to interrupt and end the method flow of this embodiment, instead of 1235¾¾twf.doc / 006 = 变 = 机 原 # 's start-up day and night. Step 3006 may be the same or different. Drinking bank, and. If used If you don't want to interrupt, you can set it in step 312 and f. Then the projector will start to read in batches;; i will be used to replace the original startup day. In this implementation, projection = within = flash memory Store the start-up day, and between the external device and the flash money body, the block data will be temporarily stored in the picture buffer data, and the movie camera will read it from the external device in step 314-part = step_316 将此- Part of the picture file data is written into the memory; step 318 reads part of the slot data from the §memory buffer, and writes this part of the picture file data to the flash memory at step 320 to replace the original There is a start-up day. _ ’You will check whether the picture broadcast is completed. If it is not completed, go back to step 314 and continue reading the picture file. The reason for reading in batches is that the capacity of the memory buffer is limited and may not be able to accommodate the entire threshold. As long as it is read in batches, the size of the memory buffer will not limit the size of the graph lion ’, and the graph can be analyzed at the highest resolution. Figure "After the transmission element is completed, the process of this embodiment will return to step 304 'The projector will restart, and a new startup screen will be displayed at this time. Then the user can choose to end the process at step 306' or press; The preset key combination 're-enters the personalization mode again and replaces the startup daytime surface. With the startup daytime personalization function, not only the added value of the projector can be increased, but also the company name and identification pattern can be added to the startup daytime surface. As a publicity, in addition, a property right declaration is added to the startup screen, even if the projector is stolen, it is not easy to sell stolen goods, which can reduce the chance of theft. [〇c / 006 As can be seen from the above description, the method for personalizing the startup screen of the projector proposed by the present invention Since the image file replacing the boot screen is from an external device, the source is more diverse than the captured projection image of the prior art. Moreover, this embodiment transmits the image file in a batch manner, so the size of the memory buffer is not Limit the size of the image file. The image file can reach the highest resolution allowed by the projector. It will not be distorted. Although the present invention has been disclosed in the preferred embodiment as above, it is not intended to limit the present invention. Anyone who listens to the essence of the present invention and the norm __ can make some changes and Retouching, so the scope of protection of the present invention shall be determined by the scope of the attached patent application.
