Description of the invention: [Technical field to which the invention pertains] This U is a test method, in particular, an automatic test method for testing an image display function of an electronic product. [Prior Art] The digital electronic products that are popular in the field of the 7th society are usually equipped with display devices that can be used to facilitate user operations or enhance entertainment effects. In order to provide end users with stable and reliable products, these products are in the process. All functions are subject to rigorous testing. The function of the image display device S is the essential s々, s A + 4 J 之 卽 卽. In order to ensure the function is normal, the motherboard function field of the Tan W is to perform the image display function of the image display function to judge the image or video played by the device through the human eye. This kind of test method Weimeng admitted, ~ 10,000 to go early, but the biggest problem is that manual manual testing, manual judgment of test results, low efficiency, workers are prone to fatigue, resulting in test errors. SUMMARY OF THE INVENTION In view of the above, there is a need for an exclusive test method for testing the visual display function of an electronic product. #Ig - , , t . - A kind of image display test method, including the following steps: the electronic device is connected to a computer, and the image is automatically played. The computer system is equipped with a fine system and a fine system. a sample image and an image comparison test program; the electric device issues an instruction to play an image; the electronic device to be tested sets the image automatic playing program, prepares a response command, and executes a digital image a signal; the 201003089 acquires the digital image signal, and compares the original image into a pixel with the sample image within an allowable error range, and the image test passes; the beam; if the comparison analysis The result exceeds the allowable error range, = new test 'If you select ', then repeat the above test ^ test process ends. Right or no, the present invention provides the user with an automatic test method for testing the display function of the sub-product. This test program is controlled without manual intervention; it does not == all saves test time and cost. The test accuracy rate is as follows: [Embodiment]: Read:: The image display automatic test method of the present invention is used to test the electronic device 1 =. The image display of the present invention is implemented automatically by the method $1 and the electronic device. The electronic device 10 to be tested has an image display chip 13 disposed in the electronic device 1G, and the image display chip 13 has an image signal output terminal 15. The computer system 20 has a serial interface 21 and a universal serial interface (usb interface) 23. A data line 30 is connected to the serial w side 1 of the computer system 20 and the data transmission 埠 1:1. The image display wafer U is connected to the computer system <foot interface 23 via 'USB controllers'. An image automatic playing program is set in the electronic device 1G to be tested. A sample image and an image test process are set in the computer system 20 201003089. The test steps of the image display automatic test method shown in FIG. 2' are as follows: ^When the first, the The electronic measuring device 10 is connected to the computer system 20 in the manner described above. At the beginning of the test, the image test program in the computer line 20 is initialized by the serial interface 21. After that, the computer system 2G sends a test image display chip 13 command to the electronic device 1 to be tested through the serial two=21. After receiving the test instruction, the electronic device under test 10 executes the image playing program and starts playing the image. At the same time, the image signal output terminal 15 of the image display wafer p rotates the digital image nickname corresponding to the playback image. The digital image signal is transmitted through the USB controller 5 to the USB interface 23 of the computer system 20. The computer system 20 obtains a digital image signal by reading the USB controller 50, and restores the digital image signal to an image, and performs pixel contrast analysis with the sample image. If the comparison result is within the error range set by the computer system 2, the image test passes 'and the test result is displayed on the display of the computer system'. The test ends; if the comparison result exceeds the error range set by the system, the image The test failed. 'The image display function of the electronic device under test is not qualified. The test result is displayed on the display of the computer system and select whether to re-enter the test program. If retesting, repeat the previous steps; if you do not re-enter the test program, the test process ends. The image display non-automatic test method of the present invention is suitable for testing various electronic products having image display functions. The testing process is completely controlled by the test program, no manual intervention is required; there is no misjudgment due to the fatigue of the tester or the off-line of the 201003089; the test accuracy is improved, the test time and cost are saved. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a block diagram of an apparatus for implementing the image display test method of the present invention. 2 is a flow chart showing the operation of the image display test method of the present invention.
