[0044] Please refer to Figure 1 , and with reference Figures 2 to 6 . Figure 1 The figure is a flow chart illustrating an image capturing method according to one embodiment of the present disclosure. Figures 2 to 6 Schematic diagram illustrating different steps of an image capturing method according to an embodiment of the present disclosure. Figure 1 As shown, in this embodiment, the image capturing method mainly includes step S101 to step S107.

[0045] Step S101 : providing an image capturing area 111 on the display screen 110 of the user device 100 .

[0046] Step S102 : providing an indication area 112 in the image capturing area 111 .

[0047] Step S103: Identify each license plate in the indication area 112 .

[0048] Step S104: Calculate the license plate area of ​​each license plate in the indication area 112 .

[0049] Step S105 : Calculate the center point distance between the center point of each license plate in the indication area 112 and the center point C0 of the indication area 112 .

[0050] Step S106: Mark the license plate with a license plate area greater than half of the maximum license plate area and a minimum center point difference.

[0051] Step S107 : capturing an image including the marked license plate in the image capturing area 111 .

[0052] 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 camera module (not shown). The camera module is configured to capture scenes around the user device 100. The display screen 110 is configured to display the scenes captured by the camera module in the image capture area 111.

[0053] like Figures 2 to 6 As shown, in this embodiment, the image capture area 111 takes the scene of a vehicle having the license plate 900A and / or the license plate 900B as an example.

[0054] In some implementations, step S103 includes step S103a.

[0055] Step S103a: Identify each license plate based on at least one feature.

[0056] In some embodiments, the at least one feature includes English letters and numbers with a predetermined format / number of digits and a predetermined license plate length-to-width ratio, but the disclosure is not limited thereto. For example, the predetermined format may include the font format of the license plate words of various types of vehicles that comply with local regulations and / or the arrangement order format of English letters and numbers, but the disclosure is not limited thereto. For example, the license plate length-to-width ratio may be a specific range of length-to-width ratios of license plates of various types of vehicles that comply with local regulations.

[0057] like Figure 2 As shown, in this embodiment, the indication area 112 has a center point C0. The license plate 900A has a center point C1. The center point C1 of the license plate 900A is at a center point distance D1 from the center point C0. Since only the license plate 900A appears in the indication area 112, the license plate 900A is the license plate with the largest license plate area and the smallest center point distance in the indication area 112. Therefore, according to step S106, the license plate 900A is Figure 2 A medium license plate is marked because it meets the conditions of having a license plate area greater than half the maximum license plate area and a minimum center point difference.

[0058] In some implementations, step S106 includes step S106a.

[0059] Step S106a: providing a marking area 115 in the image capturing area 111 to mark the license plate.

[0060] like Figures 2 to 5 As shown, in this embodiment, the indication area 112 can be marked by a frame line composed of solid lines, and the marking area 115 can be marked by a frame line composed of dotted lines, so as to improve the clarity of identification when the user operates the user device 100, but the present disclosure is not limited to this. In actual 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.

[0061] like Figure 3 As shown, in this embodiment, when the user moves the user device 100 so that at least a portion of the license plate 900A and the license plate 900B appear in the indication area 112 , according to step S106 , one of the license plate 900A and the license plate 900B will be marked.

[0062] In some embodiments, Figure 3In the image captured by the image capture area 111, the license plate 900A has a slightly larger license plate area than the license plate 900B (i.e., the license plate 900A has the largest license plate area), and the center point difference D1 between the center point C1 and the center point C0 of the license plate 900A is smaller than the center point difference D2 between the center point C2 and the center point C0 of the license plate 900B (i.e., the license plate 900A has the smallest center point difference). Figure 3 The middle is marked because it meets the conditions of having a license plate area greater than half of the maximum license plate area (i.e. the license plate area of ​​license plate 900A itself) and a minimum center point difference.

[0063] In some embodiments, Figure 3 In the image captured by the image capture area 111, the license plate 900A has a slightly smaller license plate area than the license plate 900B (i.e., the license plate 900B has the largest license plate area), but the center point difference D1 between the center point C1 and the center point C0 of the license plate 900A is smaller than the center point difference D2 between the center point C2 and the center point C0 of the license plate 900B (i.e., the license plate 900A has the smallest center point difference). Therefore, according to step S106, the license plate 900A is Figure 3 The middle license plate is marked because it meets the conditions of having a license plate area greater than half of the maximum license plate area (i.e., the license plate area of ​​license plate 900B) and a minimum center point difference.

[0064] In some implementations, the image capturing method further includes step S108 .

[0065] Step S108 : further providing a guidance information display area 114 in the image capturing area 111 .

[0066] like Figure 3 As shown, in this embodiment, the guide information display area 114 is indicated by a dotted line. The guide information display area 114 provides a dialog box 114a.

[0067] In some implementations, step S108 further includes step S108a.

[0068] Step S108 a : When the license plate with a license plate area larger than half of the maximum license plate area and a minimum center point difference moves out of the indication area 112 , providing guidance instructions in the guidance information display area 114 .

[0069] like Figure 3As shown, in this embodiment, when the marked license plate 900A is found to be moved outside the indication area 112 during the execution of step S106 according to the image capture method disclosed herein, a dialog box 114a may be provided in the guidance information display area 114, and a guide instruction may be displayed in the dialog box 114a. For example, the dialog box 114a may display a guide instruction of "Please confirm that the license plate is in the area below!", but the disclosure is not limited thereto. The aforementioned guide instruction may instruct the user to move the user device 100 to adjust the viewing angle of the camera module, so that the marked license plate 900A may be located in the indication area 112.

[0070] In some embodiments, when the image capture method of the present disclosure executes step S106 and finds that the marked license plate 900A is not presented in a predetermined ratio, a dialog box 114a may be provided in the guidance information display area 114, and a guide instruction may be displayed in the dialog box 114a. For example, the dialog box 114a may display a guide instruction of "Please come closer!", but the present disclosure is not limited thereto. The aforementioned guide instruction may instruct the user to move his user device 100 to adjust the distance between the camera module and the license plate 900A, thereby allowing the marked license plate 900A to be presented in a predetermined ratio in the indication area 112. In this way, personal safety issues caused by the user being too close to the lane can be avoided.

[0071] In some embodiments, the predetermined ratio is the ratio (e.g., width ratio or area ratio) of the license plate 900A located in the indication area 112 relative to the image capture area 111, but the disclosure is not limited thereto. For example, the width ratio of the license plate 900A relative to the image capture area 111 is between 1 / 4 and 3 / 4, but the disclosure is not limited thereto.

[0072] like Figure 4 As shown, in this embodiment, the user continues to move the user device 100 so that the center point C1 of the license plate 900A is away from the center point C0 of the indication area 112, and the center point C2 of the license plate 900B is close to the center point C0 of the indication area 112. According to step S106, one of the license plate 900A and the license plate 900B will still be marked.

[0073] In detail, Figure 4 In the image captured by the image capture area 111, the license plate 900A has a smaller license plate area than the license plate 900B (i.e., the license plate 900B has the largest license plate area), and the center point difference D1 between the center point C1 and the center point C0 of the license plate 900A is greater than the center point difference D2 between the center point C2 and the center point C0 of the license plate 900B (i.e., the license plate 900B has the smallest center point difference). Figure 3The plate 900B is marked because it meets the conditions of having a plate area greater than half of the maximum plate area (i.e. the plate area of ​​plate 900B) and a minimum center point difference. Figure 3 The marking area 115 of the marked license plate 900A will be Figure 4 The license plate number was changed to 900B.

[0074] In some implementations, the image capturing method further includes step S108b.

[0075] Step S108b: When a license plate having a license plate area larger than half of the maximum license plate area and a minimum center point difference is marked, a timing indicator 114b is provided in the guidance information display area 114 .

[0076] like Figure 5 As shown, in this embodiment, when the license plate 900B having a license plate area greater than half of the maximum license plate area and the smallest center point difference is marked, a timing indicator 114b may be provided in the guidance information display area 114. For example, the timing indicator 114b may be presented in the form of a number, but the disclosure is not limited thereto. For example, the timing indicator 114b may count down from 3, but the disclosure is not limited thereto.

[0077] In some implementations, step S107 further includes step S107a.

[0078] Step S107a: When the countdown of the timing indicator 114b ends, capture an image.

[0079] like Figure 5 As shown, the frame presented in the image capture area 111 is the image captured when the countdown of the timing indicator 114 b ends.

[0080] In some implementations, the image capturing method further includes step S109.

[0081] Step S109 : further providing an operation area 113 on the display screen 110 , wherein the operation area 113 and the image capturing area 111 are arranged side by side.

[0082] like Figures 2 to 6 As shown, the image capture area 111 and the operation area 113 are arranged side by side in the upper and lower parts of the display screen 110 , but the present disclosure is not limited thereto.

[0083] like Figures 2 to 5As shown, in this embodiment, the operation area 113 may provide a virtual camera button 113a and a flashlight virtual button 113b, but the present disclosure is not limited thereto. The virtual camera button 113a may provide a function for users to manually capture images without automatically capturing images based on the image capture method disclosed herein. The virtual flashlight button 113b may provide a function for users to select whether to turn on the flashlight when the camera module captures images.

[0084] like Figure 6 As shown, in this embodiment, after capturing an image based on the image capturing method disclosed herein, the operation area 113 may provide a retake virtual button 113c and an upload virtual button 113d, but the disclosure is not limited thereto. The retake virtual button 113c may provide the user with a function of re-capturing an image. The upload virtual button 113d may provide the user with a function of uploading the captured image to a cloud storage device.

[0085] In some embodiments, when uploading the captured image, the satellite positioning information of the location where the image was captured can be transmitted at the same time to more clearly record the location of the vehicle parked. The clear vehicle location can help the user find the vehicle more quickly the next time it is used, saving the user time in finding the vehicle.

[0086] In some embodiments, the image capture method disclosed herein can be combined with a vehicle return system to assist users in saving vehicle return records by capturing images, thereby reducing vehicle return disputes. For example, the image capture method disclosed herein can prevent users from having to pay additional rental fees or fines after returning a vehicle because the vehicle was moved by someone else.

[0087] From the above detailed description of the specific implementation methods of the present disclosure, it can be clearly seen that in the image capture method of the present disclosure, the indication area provided in the image capture area can guide the user to obtain an image of a specific composition to ensure that the image saves specific information. By marking the license plate area that is larger than half of the maximum license plate area and the license plate with the smallest center point difference, 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 marked license plate to capture the image only after a predetermined period of time in the indication area, the stability of the image capture can be increased to obtain a clearer image. By combining the image capture method with the vehicle return system, the user can be assisted in saving the vehicle return record by capturing the image to reduce vehicle return disputes.

[0088] Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be based on the scope defined by the attached claims.
