The coupling method of the image port 120 and the image port 130 will be matched with the subsequent Figure 2 as well as Figure 3 illustrate.

[0038] Processor 110 generates a test image containing test data. First, processor 110 generates test data for verifying the image transmission process. In some embodiments, the test data may be the system time of imaging device 100. Next, processor 110 processes the test image used for the image transmission test based on the test data, so that the test image contains the test data.

[0039] For example, the test image may be an image stored in the storage unit 140, or an image output by the test machine 150 and stored in the test machine 150. In some embodiments, the test image may be a static image, a dynamic image, or a blank image.

[0040] The processor 110 may generate the test image with the test data by, for example, encoding the test data into a coded image, such as a barcode image or a QR code image, and then adding the coded image to the test image.

[0041] In some embodiments, the processor 110 outputs a test image to the image port 120 , which receives the test image and then outputs it. The output test image is then received by the image port 130 . The image port 130 then outputs the received test image to the processor 110 .

[0042] In some embodiments, after receiving the test image, the processor 110 parses the test data in the test image to generate parsed data. The processor 110 compares the parsed data with the test data and generates result data indicating whether the two contents are consistent.

[0051] Please refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a testing system 10 for an imaging device 100 according to an embodiment of the present disclosure.

[0055] Figure 4 This is a flow chart of a method 400 for testing an imaging device according to an embodiment of the present disclosure. Figure 4 Additional operations are provided before, during, and after the process shown, and some of the operations described below may be replaced or eliminated for additional embodiments of the method. The order of these operations / processes may be interchangeable. Like reference numbers are used throughout the various figures and illustrative embodiments to designate like elements. The imaging device testing method 400 includes the following references: Figures 1 to 3 The test system 10 is described with reference to steps S41 to S43.

[0056] In step S41, the testing system 10 performs an image transmission test on the imaging device 100, and step S41 includes steps S401 to S408. Steps S42 and S43 are subsequent steps executed based on the test result of step S41.

[0057] In step S401, the processor 110 generates a coded image based on the current time data, and uses the current time data as test data. For example, the processor 110 obtains the system time of the imaging device 100 and uses it as the current time data. The system time can be measured using Coordinated Universal Time (UTC). Based on the current time data, the processor 110 generates a corresponding Quick Response Code (QR code) as the coded image, and this Quick Response Code contains the content of the current time data. In other embodiments, the coded image can be a one-dimensional or two-dimensional barcode or other image recognition barcode that can provide encoding and decoding functions.

[0058] In step S402 , a test image or other image having a coded image is outputted through the image port 120 .

[0059] The processor 110 generates and outputs a test image with a quick response code to the image port 120. The image port 120 receives and outputs the test image. In some embodiments, the test image with a quick response code is, for example, a QR code placed in the center of a blank image.

[0060] In step S403 , a test image having a coded image is received through the image port 130 .

[0061] In step S404 , the processor 110 parses the encoded image in the test image to generate restored time data.

[0062] The processor 110 parses the quick response code in the test image to obtain parsed data, and parses the quick response code including the current time data to generate restored time data.

[0063] In step S405 , the processor 110 determines whether the content of the current time data and the content of the restored time data are consistent to generate a test result.

[0064] Processor 110 determines whether the current time data and the restored time data are consistent. For example, processor 110 generates a quick response code with the current time data "9:00:00" at 9:00:00. Processor 110 then parses the quick response code to obtain and determine whether the restored time data is "9:00:00." Processor 110 then generates a corresponding test result based on whether the two contents are consistent.

[0065] If the current time data and the restored time data match, processor 110 executes step S406 and generates a test result indicating that the image signal is normal. In the aforementioned example, if both the current time data and the restored time data are "9:00:00," the two contents are consistent, indicating that the image transmission process is normal. Processor 110 then generates a corresponding test result and stores it in storage unit 140. The test result can then be displayed on a display screen on imaging device 100 or test machine 150.

[0066] The imaging device 100 executes steps S401 to S406, indicating that the image transmission process is normal, and then proceeds to step S42 to repeatedly perform the test. When the processor 110 confirms that one round of testing is completed and qualified in step S42, it will re-execute steps S401 to S406.

[0067] If the current time data and the restored time data are inconsistent, processor 110 executes step S408 to generate a test result indicating an image signal anomaly. In the aforementioned example, if the restored time data is not "9:00:00," the two contents are inconsistent, indicating an anomaly in the image transmission process. Processor 110 then generates a corresponding test result and stores it in storage unit 140.

[0068] The imaging device 100 proceeds to step S408 , indicating that the image transmission process is abnormal, and then proceeds to step S43 , confirming that the test is unqualified, and presenting the test result through the display screen of the imaging device 100 or the test machine 150 .

[0069] In some other embodiments, the imaging device testing method 400 described above may be implemented as a computer program and stored in the storage unit 140. The storage unit 140 includes a non-transitory computer-readable recording medium or other device with storage capabilities. This computer program includes one or more computer-executable instructions. These computer-executable instructions may be executed by the processor 110 in the imaging device 100 to perform the imaging device testing method 400 described in the various embodiments described above.

[0070] The imaging device testing system and method disclosed herein can automate the image transmission verification process and assist in judgment through coded images. This not only simplifies the manual verification process but also improves verification accuracy.

Those skilled in the art should understand that they can easily use an embodiment of the present disclosure as a basis for designing or modifying other processes and structures to achieve the same purposes and / or achieve the same advantages of the embodiments introduced herein.
