For the sake of clear illustration, many practical details will be described together in the following description. However, it should be understood that these practical details are not used to limit the present disclosure. That is to say, in some embodiments of the present disclosure, these practical details are unnecessary. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be illustrated in a simple schematic manner in the drawings.

[0041] Please refer to Figure 1 and cooperate with the reference to Figures 2 to 5 . Figure 1A flowchart for illustrating an image capturing method according to an embodiment of the present disclosure. Figures 2 to 5 A schematic diagram for illustrating different steps of an image capturing method according to an embodiment of the present disclosure. As Figure 1 shown, in this embodiment, the image capturing method mainly includes steps S101 to S105.

[0042] Step S101: Provide an image capturing area 111 on the display screen 110 of the user device 100.

[0043] Step S102: Provide an indication area 112 in the image capturing area 111.

[0044] Step S103: After identifying the license plate 900 based on at least one feature in the image capturing area 111, mark the license plate 900.

[0045] Step S104: Determine whether the marked license plate 900 is located in the indication area 112 and presented at a predetermined ratio.

[0046] Step S105: After the result of the determination is yes, capture an image including the license plate 900 in the image capturing area 111.

[0047] In some embodiments, the user device 100 is, for example, a smart phone, but the present disclosure is not limited thereto. In some embodiments, the user device 100 further includes a photography module (not shown in the figure). The photography module is configured to capture the scene around the user device 100. The display screen 110 is configured to display the scene captured by the photography module in the image capturing area 111.

[0048] As Figures 2 to 5 shown, in this embodiment, the image capturing area 111 shows the scene of a vehicle with a license plate 900 as an example.

[0049] In some embodiments, the foregoing at least one feature includes English letters and numbers with a predetermined format / digit number and a predetermined license plate aspect ratio, but the present disclosure is not limited thereto. For example, the foregoing predetermined format may include the font format of the license plate characters of various transportation vehicles conforming to local regulations and / or the arrangement order format of English letters and numbers, but the present disclosure is not limited thereto. For example, the foregoing license plate aspect ratio may be a specific range of the aspect ratios of the license plates of various transportation vehicles conforming to local regulations.

[0050] As Figure 2 shown, in this embodiment, since the photography module does not capture the vehicle from directly behind, the aspect ratio of the license plate 900 shown in the image capturing area 111 does not conform to the predetermined license plate aspect ratio. Therefore, the license plate 900 is not identified or marked because it does not have the foregoing at least one feature.

[0051] In some embodiments, the image capturing method further includes step S106a.

[0052] Step S106a: Further provide a guiding information display area 114 in the image capturing area 111.

[0053] As Figure 2 shown, in the present embodiment, the guiding information display area 114 is represented by a dotted line. The guiding information display area 114 provides a dialog box 114a. When the license plate 900 is not recognized in the image capturing area 111 when step S103 of the image capturing method according to the present disclosure is executed, the dialog box 114a can be provided in the guiding information display area 114, and guiding instructions are displayed in the dialog box 114a. For example, the dialog box 114a can display guiding instructions such as "Please face the license plate directly and confirm that the license plate is within the lower area!" However, the present disclosure is not limited thereto. The foregoing guiding instructions can instruct the user to move the user device 100 so that the imaging module captures from directly behind the vehicle, and then the license plate 900 can be recognized in the image capturing area 111.

[0054] In some embodiments, the image capturing method further includes step S106b.

[0055] Step S106b: When the marked license plate 900 is not located in the indication area 112 and / or is not presented in a predetermined proportion, provide guiding instructions in the guiding information display area 114.

[0056] As Figure 3 shown, in the present embodiment, when it is found that the marked license plate 900 is not located in the indication area 112 when step S104 of the image capturing method according to the present disclosure is executed, the dialog box 114a can be provided in the guiding information display area 114, and guiding instructions are displayed in the dialog box 114a. For example, the dialog box 114a can display guiding instructions such as "Please confirm that the license plate is within the lower area!" However, the present disclosure is not limited thereto. The foregoing guiding instructions can instruct the user to move the user device 100 to adjust the viewing angle of the imaging module, and then the marked license plate 900 can be located in the indication area 112.

[0057] In some embodiments, when it is found that the marked license plate 900 does not appear in a predetermined proportion when performing step S104 according to the image capturing method of the present disclosure, a dialog box 114a can be provided in the guidance information display area 114, and guidance instructions can be displayed within the dialog box 114a. For example, the dialog box 114a can display guidance instructions such as "Please get closer!" However, the present disclosure is not limited thereto. The foregoing guidance instructions can instruct the user to move their user device 100 to adjust the distance between the imaging module and the license plate 900, so that the marked license plate 900 appears in the indication area 112 in a predetermined proportion. Thereby, the personal safety problem caused by the user getting too close to the lane can be avoided.

[0058] In some embodiments, the foregoing predetermined proportion is the proportion of the license plate 900 located in the indication area 112 relative to the image capturing area 111 (such as the width proportion or the area proportion). However, the present disclosure is not limited thereto. For example, the width proportion of the license plate 900 relative to the image capturing area 111 ranges between 1 / 4 and 3 / 4. However, the present disclosure is not limited thereto.

[0059] In some embodiments, step S103 includes step S103a.

[0060] Step S103a: Provide a marking area 115 in the image capturing area 111 to mark the license plate 900.

[0061] As Figures 2 to 4 shown, in the present embodiment, the indication area 112 can be marked by a frame line formed by solid lines, and the marking area 115 can be marked by a frame line formed by dotted lines to improve the clarity of identification when the user operates the user device 100. However, the present disclosure is not limited thereto. In practical applications, the indication area 112 and the marking area 115 can also be marked by frame lines or color blocks of different types or colors.

[0062] In some embodiments, the image capturing method further includes step S106c.

[0063] Step S106c: When the marked license plate 900 is located in the indication area 112 and appears in a predetermined proportion, provide a timing indicator 114b in the guidance information display area 114.

[0064] As Figure 4As shown, in the present embodiment, when it is found that the object is located in the indication area 112 and presented at a predetermined ratio when performing step S104 according to the image capturing method of the present disclosure, a timing indicator 114b can be provided in the guiding information display area 114. For example, the timing indicator 114b can be presented in the form of numbers, but the present disclosure is not limited thereto. For example, the timing indicator 114b can count down from 3, but the present disclosure is not limited thereto.

[0065] In some embodiments, step S105 further includes step S105a.

[0066] Step S105a: If the judgment result is yes, capture an image when the countdown of the timing indicator 114b ends.

[0067] As Figure 5 shown, the image presented within the image capture area 111 is the image captured when the countdown of the timing indicator 114b ends.

[0068] In some embodiments, the image capturing method further includes step S107.

[0069] Step S107: Further provide an operation area 113 on the display screen 110, where the operation area 113 is arranged side by side with the image capture area 111.

[0070] As Figures 2 to 5 shown, the image capture area 111 and the operation area 113 are arranged side by side vertically on the display screen 110, but the present disclosure is not limited thereto.

[0071] As Figures 2 to 4 shown, in the present embodiment, the operation area 113 can provide a capture virtual button 113a and a flash virtual button 113b, but the present disclosure is not limited thereto. The capture virtual button 113a can provide the function for a user who does not need to automatically capture an image based on the image capturing method of the present disclosure to capture an image manually. The flash virtual button 113b can provide the function for the user to select whether to turn on the flash when the imaging module captures an image.

[0072] As Figure 5 shown, in the present embodiment, after capturing an image based on the image capturing method of the present disclosure, the operation area 113 can provide a retake virtual button 113c and an upload virtual button 113d, but the present disclosure is not limited thereto. The retake virtual button 113c can provide the function for the user to retake an image. The upload virtual button 113d can provide the function for the user to upload the captured image to a cloud storage device.

[0073] In some embodiments, when uploading the captured image, the satellite positioning information of the location where the image is captured can be transmitted simultaneously to record the parking position of the vehicle more clearly. The clear vehicle position can assist the user to find the vehicle more quickly the next time, saving the user's time to search for the vehicle.

[0074] In some embodiments, the image capturing method disclosed herein can be combined with the vehicle return system to assist the user in saving the vehicle return record by capturing images, thereby reducing vehicle return disputes. For example, the image capturing method disclosed herein can avoid situations where the user needs to bear additional rental fees or pay fines because the vehicle has been moved by others after returning the vehicle.

[0075] From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the image capturing method of the present disclosure, the indication area provided in the image capturing area can guide the user to obtain an image with a specific composition to ensure that the image stores specific information. By guiding the user to present the license plate in the indication area at a predetermined ratio, the purpose of enhancing the safety of the user during the image capturing process can be achieved. By marking the license plate, the user's recognition of the license plate can be improved, thereby reducing the time for the user to capture the image. By limiting the image to be captured only when the marked license plate is presented in the indication area at a predetermined ratio for a predetermined duration, the stability during image capturing can be increased to obtain a clearer image. By combining the image capturing method with the vehicle return system, the user can be assisted in saving the vehicle return record by capturing images to reduce vehicle return disputes.

[0076] Although the present disclosure has been disclosed as above in embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the scope defined by the appended claims.
