Detailed ways

The implementation of this embodiment will be described in detail below in conjunction with the accompanying drawings.

In the process of life or work, people often use various cards such as personal certificates and bank cards. Among them, being used as a credential is a common use of a card. In some scenarios, the card used for the voucher needs to be handed over to others for storage. However, the original card cannot be directly handed over to others for storage. Therefore, what is actually used as a certificate is a substitute for the card, such as a photocopy or a scanned copy.

Generally speaking, the original card is required to make a replacement card. For example, when making a copy of an ID card, the original ID card needs to be used for printing. For another example, when making a scanned copy of an ID card, the original ID card is also required to be scanned.

However, for most users, it is seldom to carry the original card at all times. In this way, it will be very inconvenient for users who do not carry the original card in the scenario where a replacement card is temporarily needed.

Therefore, in the related technology, the user will use the electronic device to collect the image of the original card, and obtain the photo containing the card as the card information. In this way, the user can make a substitute at any time according to the above card information. For example, a user uses an electronic device to take a photo of an ID card to obtain a photo containing the ID card. When the user needs to make a copy of the ID card, the electronic device can respond to the user's operation and send the photo containing the ID card to the printing device, and the printing device will print it.

Like other photos taken by electronic devices, the card information obtained by taking photos is uniformly stored in the gallery of electronic devices. However, with more and more photos in the gallery, the above card information is easily overwhelmed. The large number of photos in the gallery also makes it difficult for users to find card information. That is, in the related art, there is a problem of poor human-computer interaction in the process of managing card information.

In order to improve the above problems, an embodiment of the present application provides a card information management method. In order to improve the process of finding card information, the problem of poor human-computer interaction is managed and displayed by the memo application of the electronic device in a unified manner.

Taking the electronic device as a mobile phone as an example, (a) in FIG. 1 shows the desktop 101 of the mobile phone, also known as the main interface, and the desktop 101 includes icons of application programs (Application, APP) installed in the mobile phone, such as memo The icon 102 of the APP. The mobile phone may display an interface 103 as shown in (b) in FIG. 1 , also called the first interface, in response to the user's operation on the icon 102, also called the first operation, such as a click operation. Among them, the interface 103 includes a plurality of created notes, such as memo content 1, memo content 2, and memo content 3, etc., and the above notes are notes in conventional memos, also called memo notes. The memo note can be used to instruct to display the corresponding general memo information, so that when the mobile phone receives an operation on the memo note, it can display an interface containing the corresponding memo item.

In addition, the above-mentioned interface 103 also includes a note option 104 and a certificate option 105 .

The aforementioned note option 104 and certificate option 105 respectively refer to different functional modes of the memo app. For example, the note option 104 above corresponds to the note taking function mode of the memo APP. The above certificate option 105, also known as the first control, corresponds to the certificate management function mode of the Memo APP. The above-mentioned interface 103 is a display interface corresponding to the note recording function mode, and the interface 106 shown in (c) in FIG. 1 is a display interface corresponding to the certificate management function mode.

Exemplarily, the mobile phone can switch the display interface 106 in response to the user's selection operation on the certificate option 105 in the interface 103 , for example, a click operation, also referred to as a second operation.

The above-mentioned interface 106 can also be called a card management interface, and the interface 106 also includes a note option 104 and a certificate option 105 . The mobile phone may also switch the display interface 103 in response to the user's selection operation on the note option 104 in the interface 106 , for example, a click operation.

Different from the interface 103, the interface 106 also includes a plurality of card notes, such as a note 107 titled ID 1, a note 108 titled ID 2, and a note 109 titled ID 3, etc. Each card note corresponds to a created card information. In other words, each card note is also an access entry for card information, which is used to trigger the display of the card information. For example, the mobile phone can respond to the user's operation on the note 107, as shown in (d) in FIG. 1, the mobile phone can display the card information of the certificate 1.

In this way, in the Memo APP, the card information can be managed and displayed separately. When the user needs to inquire about the card information, he only needs to trigger the display interface 106 of the mobile phone through an operation, which is convenient for the user to find the card information, and at the same time, improves the efficiency of human-computer interaction.

Certainly, besides the mobile phone, the above-mentioned electronic device may also be other devices.

In some embodiments, the Android system is divided into four layers, which are respectively the application program layer, the application program framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer from top to bottom.

The application layer can consist of a series of application packages.

Exemplarily, the application program layer may include: APPs such as call, memo, browser, camera, gallery, calendar, short message, and desktop.

The application framework layer provides an application programming interface (application programming interface, API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

Exemplarily, the application framework layer may include a print manager, an alarm manager (AlarmManager), a window manager, a content provider, a view system, a resource manager, a notification manager, and the like.

Wherein, the print manager is a print frame provided by the mobile phone, and the PrintJob print class provided by the above print manager can be used to create a print job, that is, convert the content to be printed into a printable document. In addition, the above-mentioned print manager can also send a document to be printed (such as a print job) to the connected printing device, so as to instruct the printing device to complete the printing job. In addition, the application framework layer also includes a print adapter that cooperates with the print manager, and the print adapter is used to select a printer and print options.

The above-mentioned AlarmManger provides an access interface to the timing service of the system, so that the developer can arrange to run the target application at a specific time (eg, a specified time in the future). When the system time reaches the reminder setting time, the system broadcasts the pre-registered intent (Intent). If the target application has not been started at this time, the system can also automatically start the target application. Even if the mobile phone goes to sleep, it can also wake up the processor, such as waking up the central processing unit (CPU), which can ensure that the CPU can work normally every time it needs to perform a specific task.

The window manager described above is used to manage window programs. The window manager can get the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc.

The above-mentioned content providers are used to store and obtain data, and make these data accessible to applications. Said data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebook, etc.

The above view system can be used to build the display interface of the application. Each display interface can consist of one or more controls. Generally speaking, controls may include interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets (Widgets).

The resource manager mentioned above provides various resources for the application, such as localized strings, icons, pictures, layout files, video files and so on.

The above-mentioned notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to notify the download completion, message reminder, etc. The notification manager can also be a notification that appears on the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, sending out prompt sounds, vibrating, and flashing lights, etc.

As another example, the system library may include multiple functional modules. For example: layer integrator (SurfaceFlinger), media library (Media Libraries), 3D graphics processing library (eg: OpenGL ES), 2D graphics engine (eg: SGL), etc. SurfaceFlinger is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications. The media library supports playback and recording of various commonly used audio and video formats, as well as still image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing, etc. 2D graphics engine is a drawing engine for 2D drawing.

Android Runtime includes core library and virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

The core library consists of two parts: one part is the function function that the java language needs to call, and the other part is the core library of Android.

The application layer and the application framework layer run in virtual machines. The virtual machine executes the java files of the application program layer and the application program framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The kernel layer is the layer between hardware and software. The kernel layer includes at least a camera driver, an audio driver, a sensor driver, etc., which are not limited in this embodiment of the present application.

The above-mentioned hardware structure and software system constitute an operating environment for implementing the technical solutions provided by the embodiments of the present application. Taking the electronic device as a mobile phone as an example, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings. Wherein, in the description of the present application, unless otherwise specified, "at least one" refers to one or more, and "multiple" refers to two or more than two. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order, and words such as "first" and "second" do not necessarily limit the difference.

In some embodiments, the above-mentioned card note may be created by the mobile phone in response to the user's operation in the memo APP. As shown in Figure 3, the above method may include the following steps:

S101. The mobile phone displays a card management interface.

In some embodiments, the mobile phone may display the interface 103 in response to the user's selection operation on the icon of the memo APP, such as clicking, the memo runs in the note-taking function mode by default. Afterwards, in response to the user's click operation on the certificate option 105 on the interface 103, the mobile phone triggers the memorandum to enable the certificate management function mode, and displays the interface 106, that is, the card management interface.

S102. The mobile phone displays a note creation interface in response to the user's operation on the card management interface.

In some embodiments, the user can trigger the mobile phone to display the above-mentioned note creation interface by operating a designated control. Wherein, the above specified control may be a control for instructing to create a card note in the card management interface, such as the control 401 shown in (a) of FIG. 4 , which is also called the second control. That is, after the mobile phone receives the user's operation on the control 401, such as a click operation, the note creation interface can be displayed, such as the interface 402 shown in (b) in FIG. 4 .

In some other embodiments, the user can also use a specified operation to trigger the mobile phone to display the above note creation interface. The specified operation may also be a preset gesture input by the user on the note creation interface, such as an S-shaped gesture or a slide gesture. The preset gesture can be preconfigured in the mobile phone. In addition, the mobile phone can prompt the user with the preset gesture and the function triggered by the preset gesture when displaying the card management interface. For example, prompting the preset gesture can trigger the mobile phone display interface 402 to realize the function of creating card information.

It can be understood that the above note creation interface may be an interface for creating card information. Users can configure card information in the note creation interface.

S103. The mobile phone receives the user's operation on the note creation interface, and creates a card note according to the configuration process template.

Wherein, the above-mentioned note creation interface includes a functional interface for configuring card information, such as called the first interface. As an example, the first interface in the note creation interface can be divided into an interface for configuring image data, an interface for configuring text, and the like.

In some embodiments, the mobile phone can acquire card information according to the user's operation on the first interface.

Exemplarily, the interface 402 includes multiple first interfaces. Wherein, the above-mentioned first interface includes a control 403 named "picture", a control 404 named "voice" and a control 405 named "handwriting". The picture control 403 is an interface for entering image data. The aforementioned voice control 404 and handwriting control 405 are interfaces for inputting text. The user can determine the card information from the image dimension by operating the picture control 403 . For example, by operating the picture control 403, an image including a card is entered. In this way, the mobile phone can acquire the image information of the original card in response to the user's operation on the picture control 403 .

Of course, the user can also determine the card information from the text dimension by operating the voice control 404 or the handwriting control 405 , for example, by operating the voice control 404 or the handwriting control 405 to mark the use authority and expiration date of the card. In this way, the mobile phone can respond to the user's operation on the voice control 404 or the handwriting control 405 , receive the user's input content, and convert it into text for display on the interface 402 . For example, the mobile phone may collect sound data in response to the user's click operation on the voice control 404, and convert the collected sound data into text. For another example, in response to the user's click operation on the handwriting control 405, the mobile phone can obtain the user's sliding track on the display screen, and convert it into unique text, that is, text with personal handwriting characteristics.

It is not difficult to understand that in the above embodiments, at least one method may be used to determine the card information from the text dimension. Similarly, in the process of obtaining the card information, the card information in the image dimension can also be obtained in at least one way. For example, the method of enabling the camera in real time to shoot, the method of obtaining from the existing library, and the method of enabling the camera in real time to scan the card, etc.

Exemplarily, the mobile phone may display a selection window 406 as shown in (c) of FIG. 4 after receiving that the user clicks on the picture control 403 . Wherein, the selection window 406 includes at least one selection item, for example, the selection item 407 named "photograph", the selection item 408 named "scan", and the selection item 409 named "gallery". Each option represents a way to obtain card information. For example, the photographing option 407 is used to indicate that the image information including the card is obtained by direct photographing. The scan selection item 408 is used to instruct to call the camera to scan the original card, so as to obtain the card information. The gallery selection item 409 is used to instruct to search the stored image information containing the card from the gallery.

Take the card card information collection by direct shooting as an example. When the mobile phone receives the user's operation on the photographing option 407, the mobile phone may display a viewfinder interface for photographing. Wherein, the viewfinder frame in the viewfinder interface can display a preview image collected by the camera. As shown in (a) of FIG. 5 , the viewfinder interface 501 includes a viewfinder frame 502 , and the viewfinder frame 502 displays a captured preview image including a contract and a bank card.

In addition, the viewfinder interface 501 also includes a control 503 for instructing shooting. After the mobile phone receives the user's operation on the control 503, the mobile phone determines the preview image in the viewing frame 502 as the card information to be selected, and displays the interface 504 shown in (b) in FIG. 5 . As such, image 505 is included in interface 504 . This image 505 is an image including a contract and a bank card. In addition, the interface 504 may also include a retake control 506 , a save control 507 and a print control 508 . Wherein, the retake control 506 is used to instruct to discard the image 505 and recapture. The save control 507 is used to indicate that the confirmation image 505 is card information and saved. The print control 508 is used to instruct to determine that the image 505 is card information and print it.

In other words, when the mobile phone receives the user's operation on the retake control 506, such as a click operation, the mobile phone displays the viewfinder interface 501 again, so as to re-capture.

When the mobile phone receives the user's operation on the save control 507, such as a click operation, as shown in (c) in Figure 5, the mobile phone displays the interface 402 again, and the interface 402 at this time includes the collected card information (that is, image 505), to indicate that the scan is complete. In addition, the interface 402 also includes an input box for indicating the input title, and the mobile phone can determine the name of the card information created this time according to the user's input operation in the input box, so as to facilitate user division. Afterwards, when the mobile phone receives an operation on the confirmation control 410, the mobile phone generates a card note according to the content in the interface 402.

When the mobile phone receives the user's operation on the printing control 508, such as a click operation, the mobile phone sends the image 505 as card information to the connected printer for printing.

Take the card card information obtained by scanning as an example. As shown in (a) in Figure 6, the user operates the scan option 408 in the interface 402, and the mobile phone can receive the user's operation on the scan option 408, and the mobile phone can display the screen shown in (b) in Figure 6 interface 601 . A selection window 602 is included in the interface 601 . Wherein, the selection window 602 includes multiple configuration items. Different configuration items can correspond to process templates for configuring different cards. In some embodiments, for different types of cards, the number of card sides to be scanned may be different. For example, an ID card usually needs to be scanned on both sides, while a student ID card only needs to scan the front side. At the same time, different types of cards may have different shapes and sizes. For example, an ID card is a smaller rectangle, while a graduation certificate is a larger rectangle. Therefore, different types of cards require different configuration process templates. However, for cards of the same type, the required configuration process templates can be the same.

In some examples, dedicated provisioning process templates may be preset for common cards. For example, for ID cards, bank cards, passports, driving licenses and driver’s License configuration item 606 and driver's license configuration item 607. Among them, each configuration item corresponds to the process template for configuring the corresponding certificate. In addition to the dedicated process templates corresponding to the above enumerated types of cards, dedicated process templates can also be preset for other cards, which is not specifically limited in this embodiment of the present application.

In addition, a configuration process template applicable to all cards can also be preset, such as a common process template. In this way, the selection window 602 can also include a general configuration item 608 for enabling the general process template to obtain card information.

In some embodiments, the mobile phone can start a corresponding configuration process template according to the configuration item selected by the user in the selection window 602, thereby instructing the user to complete the configuration of the card information.

Taking the mobile phone receiving the operation on the configuration item 603 of the ID card as an example, the mobile phone can display a scanning interface 701 as shown in (a) in FIG. 7 , which is also called the fourth interface. The scanning interface 701 is used to guide the user to use the mobile phone to scan the front of the ID card. The scanning interface 701 includes a scanning frame 702 . A preview image captured by the camera can be displayed in the scanning frame 702 . Wherein, the scan frame 702 also includes a scan frame 703, which is used to indicate the ideal position of the front of the ID card (that is, the physical card) in the preview image. Understandably, the real space displayed by the preview image can be regarded as the capture range of the camera. Each image area in the preview image corresponds to an acquisition area in the acquisition range. For example, the scanning frame 703 may correspond to the collection area 1 in the collection range, then in the real space, the user puts the ID card in the collection area 1, then the ID card can be displayed in the scanning frame 703 of the preview image.

In some embodiments, the mobile phone instructs the user to adjust the position and angle between the mobile phone and the original ID card by displaying the scan frame 703, so that the front of the ID card in the collected preview image is within the scan frame 703, and the ID card The edge of is close to the scan frame 703 .

In addition, the scanning interface 701 also includes a shooting control 704 for instructing shooting.

In some embodiments, before receiving the user's operation on the shooting control 704, the mobile phone may perform preprocessing on the preview image collected by the camera.

As an example, the process that the mobile phone can preprocess the preview image captured by the camera includes: when the ID card is placed in the collection area corresponding to the scanning frame 703, the mobile phone recognizes the display area of the ID card in the preview image, such as is the first image area. Rectangular correction is then performed on the first image area to obtain a scanned preview image of the ID card. The obtained edge information of the scanned preview image is obtained, and the edge information is displayed on the scanning interface 701 . In this way, the user can preview the size and position of the scanned image of the ID card that can be obtained by operating the shooting control 704 at this time according to the edge information displayed on the scanning interface 701 , so as to facilitate the user to decide whether to operate the shooting control 704 .

After the mobile phone receives the user's operation on the shooting control 704, the mobile phone first saves the preview image collected by the camera at this time, for example, it is called storage image 1 . According to the instruction of the scanning frame 703, the mobile phone obtains the scanned image of the front of the ID card from the stored image 1.

As an implementation, the way to obtain the scanned image of the front of the ID card from the stored image 1 may be: the mobile phone obtains the recognition area indicated by the scanned frame 703 from the stored image 1 according to the instruction of the scanned frame 703 . The above identification area is the image area enclosed by the scanning frame 703 after the scanning frame 703 is mapped to the stored image 1 . The ID card in the stored image 1 may be located in the identification area. Then, the mobile phone automatically recognizes the outline information of the ID card from the recognition area, thereby cutting out the image data indicating the ID card based on the outline information. Finally, the cropped image data is rectified to obtain a scanned image of the front of the ID card.

Understandably, the process of "the mobile phone automatically recognizes the outline of the ID card in the stored image, cuts out the image data indicating the ID card, and performs rectangle correction on the cut out image data" can also be called automatic correction. After getting the scanned image of the front of the ID card, proceed to scan the reverse side of the ID card. In some embodiments, the mobile phone may display a scanning interface 705 as shown in (b) of FIG. 7 . The scanning interface 705 is used to guide the user to use the mobile phone to scan the reverse side of the ID card. The scanning interface 705 includes a scanning box 706 . A preview image captured by the camera can be displayed in the scanning frame 706 . Wherein, the scan frame 706 also includes a scan frame 707, which is used to indicate the ideal position of the reverse side of the ID card in the preview image. In some embodiments, the mobile phone displays the scanning frame 707 to instruct the user to adjust the position and angle between the mobile phone and the original ID card, so that the reverse side of the ID card in the collected preview image is within the scanning frame 707, and the ID card The edge of is close to the scan border 707 . In addition, the scan interface 705 also includes a capture control 708 for instructing capture. After the mobile phone receives the user's operation on the shooting control 708, the mobile phone first saves the preview image collected by the camera at this time, for example, it is called the stored image 2 . According to the instruction of the scanning frame 707, the mobile phone obtains the scanned image of the reverse side of the ID card from the stored image 2. Understandably, the principle of obtaining the scanned image of the reverse side of the ID card is the same as that of obtaining the front side of the ID card, and will not be repeated here.

The above process of scanning the front and back pages of the ID card is part of the process template for configuring the ID card. During this process, the mobile phone may also switch to other configuration flow templates in response to user operations.

Exemplarily, both the scanning interface 701 and the scanning interface 705 include an ID card control 709 , a bank card control 710 , a passport control 711 and the like. Among them, the ID card control 709 is used to indicate the process template for configuring the "ID card". When scanning is performed according to the process template for configuring the ID card, the ID card control 709 is in a selected state. In addition, the above-mentioned bank card control 710 is used to indicate the configuration process template of "bank card". The aforementioned passport control 711 is used to indicate the "passport" configuration process template. Of course, it may also include a control for instructing other card configuration process templates, which will not be repeated here. In this way, the user can trigger the mobile phone to switch from the process template for configuring the ID card to other process templates by selecting the bank card control 710 or the passport control 711 . Therefore, it is convenient for the user to switch the configuration process flexibly, and the human-computer interaction is improved.

In some embodiments, the mobile phone can directly store the scanned front and back sides of the ID card as card information. In other embodiments, after the mobile phone scans the front and back of the ID card, the mobile phone can adjust the front and back of the ID card in response to user operations. Then use the adjusted front and back of the ID card as the card information and save it.

In this way, in this embodiment, configuring the process template of the ID card may also include a process of adjusting the front and back of the scanned ID card. That is, after scanning the front and back of the ID card, the mobile phone may display an interface 801 as shown in (a) in FIG. 8 , which is also called the sixth interface. The above-mentioned interface 801 includes the front and back sides of the scanned ID card. In addition, the above-mentioned interface 801 also includes controls for instructing to adjust the front and back sides of the ID card, such as manual correction controls, retake controls, watermark controls (also called third controls), encryption controls, and the like. Wherein, the manual correction control is used to trigger manual rectangle correction for the front or back of the ID card. The retake control is used to instruct to rescan the front and back of the ID card. The watermark control is used to instruct to add specific marks, such as text, pattern, etc., on the interface including the front and back pages of the ID card. The encryption control is used to trigger the addition of access rights for the front and back of the ID card.

Exemplarily, when the mobile phone receives the user's operation on the manual correction control, it may display the interface 802 shown in (b) in FIG. 8 . Wherein, the interface 802 includes a stored image 1 corresponding to the front of the ID card and a contour determination box 803 . The mobile phone can prompt the user to adjust the positions of the four vertices 804 of the contour determination frame 803 so that the adjusted contour determination frame 803 coincides with the actual contour of the ID card in the stored image 1. After confirming the operation, the mobile phone cuts out the image area displaying the ID card (that is, the image area containing the ID card) from the stored image 1 according to the outline determination frame 803, and performs rectangle correction on the image area to obtain the scanned identity card. certificate positive.

Then, the mobile phone can display the interface 805 shown in (c) in FIG. 8 . Wherein, the interface 805 includes the stored image 2 corresponding to the reverse side of the ID card and a contour determination box 806 . The mobile phone can prompt the user to adjust the positions of the four vertices 807 of the contour determination frame 806, so that the adjusted contour determination frame 806 coincides with the actual contour of the ID card in the stored image 2. After confirming the operation, the mobile phone cuts out the image area displaying the ID card (that is, the image area containing the ID card) from the stored image 2 according to the outline determination frame 806, and performs rectangular correction on the image area to obtain the scanned identity card. Negative proof. Thus, the manually corrected card information is obtained.

It can be seen that during the manual correction process, the contour information of the card (eg, ID card) in the stored image is manually determined by adjusting the position of each vertex of the contour determination frame. Thus, the image area where the card is actually displayed is more accurately cropped. In this way, after the mobile phone performs rectangle correction on the cropped image area, a more accurate scan image of the card can be obtained. In this embodiment, through the combination of automatic correction and manual correction, the obtained card scan image can better meet the user's needs, reduce the number of repeated scans by the user, and improve the efficiency of human-computer interaction in card scanning.

The above embodiment describes the manual correction of the scanned images of the front and back sides of the ID card in sequence. In some embodiments, it may be specified to perform manual correction only on the front side of the ID card, or it may be specified to perform manual correction only on the reverse side of the ID card. For example, after the mobile phone receives the user's operation on the manual correction control, if it receives the user's operation on the front of the ID card in the interface 801, such as a click operation, the interface 802 is displayed. In addition, after the manual correction of the front of the ID card is completed, the mobile phone displays the interface 801 again, and at this time the front of the ID card in the interface 801 is the manually corrected image. Similarly, if an operation on the reverse side of the ID card in the interface 801 is received, such as a click operation, the interface 805 is displayed. In addition, after the manual correction of the reverse side of the ID card is completed, the mobile phone displays the interface 801 again, and at this time, the reverse side of the ID card in the interface 801 is the manually corrected image.

For another example, when the mobile phone receives the user's operation on the retake control, the mobile phone may re-display the scanning interface 701, thereby restarting the process template for configuring the ID card.

In another example, the mobile phone receives the user's operation on the watermark control, which is also called the fifth operation, such as a click operation, and may display an interface 901 shown in (a) of FIG. 9 , also called the seventh interface. Wherein, the interface 901 includes not only the scanned image of the card (eg, the front and back sides of the scanned ID card), but also a watermark text input area. In addition, the above-mentioned interface 901 also includes a text watermark control and a handwritten watermark control.

The above-mentioned text watermark control and handwriting watermark control are both used to trigger the mobile phone to receive watermark information input by the user, such as text, specific symbols, etc., and display them in the watermark text input area. For example, when the mobile phone receives the user's operation on the text watermark control, such as a click operation, the display is as shown in (b) in FIG. 9 , and the interface 901 also includes a virtual keyboard 902 and a cursor 903 . Wherein, the user can input watermark information through the virtual keyboard 902 , so that the mobile phone can obtain the watermark information input by the user according to the user's input operation on the virtual keyboard 902 . For example, the mobile phone receives the watermark information input by the user as "this scanned copy is only for renting a house". The interface 801 at the time also includes the watermark information set by the user, such as "this scanned copy is only for rental use" displayed between the front and back of the ID card. Thus, the card information with watermark is obtained.

In addition, the cursor 903 may indicate the display position of the above watermark information in the interface 801 . Understandably, the user can click on different positions in the interface 901 to change the position of the cursor 903 . That is, the mobile phone can determine the clicked position according to the click operation received from the user on the interface 901 , and display the cursor 903 at the clicked position.

Of course, the user can also set the watermark information by operating the handwritten watermark control. For example, after the mobile phone receives the operation of the user's handwritten watermark control, the user can handwrite the watermark text in the interface, and the process of handwriting the watermark text can be regarded as a second sliding operation. The mobile phone determines the second trajectory according to the second sliding operation. And display the second track as watermark text information. Wherein, the above-mentioned second trajectory is actually a character stroke handwritten by the user with personal handwriting characteristics. After determining the second track, the user can also adjust the size and display position of the second sliding track year-on-year by operating the mobile phone. In this way, the obtained card information contains the watermark text information written by the user himself. Improve the problem that users can only write the usage rights in paper card information.

That is, the above card information can be obtained by combining the scanned image of the card and the watermark text information.

As another example, after the mobile phone receives the user's operation on the encryption control, the mobile phone may receive the access password configured by the user for the scanned front and back of the ID card, so as to obtain encrypted card information.

In addition, as shown in (c) of FIG. 9 , the interface 801 also includes a confirmation control 904 . Wherein, the confirmation control 904 is also used to indicate that the configuration of the confirmation card information is completed. When the mobile phone receives the user's operation on the confirmation control 904, the mobile phone may display an interface 1001 as shown in (a) in FIG. 10 , such as a card preview interface. The interface 1001 includes card information for storage, and the card information includes the front and back of the ID card and configured watermark information. In addition, the interface 1001 also includes a control 1002 for indicating completion and a control 1003 for indicating printing, also referred to as a fourth control. When the mobile phone receives the user's operation on the control 1002, the mobile phone can display the interface 402 again. As shown in (b) in Figure 10, the interface 402 at this time includes the card information corresponding to the ID card and an input box for indicating the input title. The name of the card information created this time, for example, if the mobile phone receives the user input "Certificate 4" in the input box of the title, then it is determined that the name of the card information created this time is "Certificate 4". Afterwards, when the mobile phone receives an operation on the confirmation control 410, the mobile phone generates a card note according to the content in the interface 402.

Above, from the process of triggering and displaying the note creation interface to determining the card information, the user operations received by the mobile phone can be regarded as the fourth operation.

Similarly, when the mobile phone receives the user's operation on the control 1003 that instructs to print, also known as the sixth operation, and generates card notes, share the card information to the printer communicating with the mobile phone, so as to make a copy of the ID card .

Afterwards, when the mobile phone displays the interface 106 again, the above-mentioned interface 106 may also be referred to as a second interface. As shown in (a) of FIG. 11 , the interface 106 also includes a card note 1101 named "Certificate 4". Understandably, in the process of creating the card note 1101, if an access password is configured, when the mobile phone receives the user's click operation on the card note 1101, the interface 1102 shown in (b) in Figure 11 can be realized , the interface 1102 includes a password input box 1103 for receiving an authentication password input by the user. After receiving the authentication password input by the user in the password input box 1103, the mobile phone compares the authentication password with the pre-configured access password, and if the two match, as shown in (c) in Figure 11, the interface 1102 The display of the password input box 1103 is canceled, and the card information corresponding to the certificate 4 is displayed, that is, the third interface is displayed. Wherein, when the above-mentioned card note 1101 is called the first card note, the card information corresponding to the above-mentioned certificate 4 may also be called the first card information. The above-mentioned click operation on the card note 1101 and/or the operation of inputting the authentication password may be referred to as a third operation.

In addition, the interface 1102 also includes a control 1104 for instructing printing, which is also called a fifth control. When the mobile phone receives the user's operation on the control 1104, which can also be referred to as the sixth operation, the card information displayed on the interface 1102 is shared with the printer communicating with the mobile phone, so as to make a copy of the ID card.

In the above example, the special process template using the ID card is enumerated to create the card information corresponding to the ID card. The special process templates for other cards are similar to the special process templates for ID cards. For example, the cards need to be scanned first, and then the scanned card information can also be adjusted in response to user operations. The difference between different dedicated process templates may be different number of scanned sides, different shapes of scanned borders, or different title types, etc.

Of course, in addition to the dedicated process template, in the embodiment of the present application, the mobile phone's memo APP also includes a general process template to meet different card scanning needs of users.

Exemplarily, as shown in (a) in Figure 12, the user can operate the general configuration item 608, so that the mobile phone can respond to the user's operation on the general configuration item 608, and display the Interface 1201 is also called the fifth interface. The interface 1201 may be used to remind the user to determine the scan frame within the range of the scan frame 1202, for example, a reminder message may be displayed to guide the user to draw the scan frame. The user can draw the shape of the scanning frame in the scanning frame 1202 according to the shape of the actually scanned card. The user's operation of drawing a scanning frame on the interface 1201 may also be referred to as a first sliding operation. The above-mentioned first sliding operation corresponds to a first track, that is, a track displayed by the mobile phone in response to the first sliding operation. For example, the required scanning card is a circular medal, and the user can draw a circular trajectory in the scanning frame 1202, so that the mobile phone responds to the user's operation in the scanning frame 1202, as shown in FIG. A scan frame 1203 is displayed in the center, and the interface 1201 displayed with the scan frame may also be referred to as a fourth interface. A preview image captured by the camera can also be displayed in the scanning frame 1202 . The scan frame 1203 is used to indicate the ideal position of the circular medal in the preview image. In some embodiments, the mobile phone instructs the user to adjust the position and angle between the mobile phone and the circular medal by displaying the scan frame 1203, so that the circular medal in the collected preview image is located within the scan frame 1203, and the medal's The edges are close to the scan border 1203 .

In some embodiments, the user can draw multiple scanning frames in the scanning frame 1202 at the same time, so that the mobile phone determines multiple scanning frames after receiving the user's first sliding operation in the interface 1201 .

In addition, the interface 1201 also includes a control 1204 for instructing shooting. After the mobile phone receives the user's operation on the control 1204, the mobile phone first saves the preview image collected by the camera at this time, and the saved preview image is also the captured preview image, for example, it is called the stored image 3 . The mobile phone acquires the scanned image of the medal from the stored image 3 according to the instruction of the scanning frame 1203 . Understandably, the principle of obtaining the scanned image of the medal is the same as the principle of obtaining the scanned image of the ID card, and will not be repeated here.

After obtaining the scan image of the medal, as shown in (d) in FIG. 12 , a confirmation window 1205 is displayed on the interface 1201 . Wherein, the determination window 1205 is used to prompt the user whether to continue scanning other sides of the card. A control 1206 indicating to continue scanning and a control 1207 indicating not to continue scanning are included in the confirmation window 1205 . Exemplarily, when the mobile phone receives the user's operation on the control 1206, the mobile phone displays the interface 1201 again.

For another example, when the mobile phone receives the user's operation on the control 1207, an interface 1301 as shown in FIG. 13 is displayed. The interface 1301 is similar to the interface 801, the difference is that the interface 1301 displays a scanned image of a medal. The user can also operate the controls in the interface 1301 (eg, manual correction control, retake control, watermark control, encryption control, etc.), thereby triggering the mobile phone to adjust the medal scan image. It should be noted that the process of adjusting the scanned image and finally creating the corresponding card note can refer to the implementation process of adjusting the front and back of the ID card and creating the corresponding card note in the aforementioned embodiment, which will not be repeated here. repeat. Obviously, the display position and size of the scanned image of the medal in the interface 1301 are determined by the scanning frame 1203.

In addition, in the case that multiple scanning frames are displayed at the same time, the user can use each scanning frame to scan to obtain a scanned image of the physical card. In this way, the mobile phone can capture multiple scan images of the physical card through multiple scan frames. Exemplarily, the multiple scans may be scans corresponding to different sides of the same physical card, or may be scans of different cards.

In some embodiments, the handset may capture a preview image in response to a user action. In the preview image, if the card appears in any scan frame, the corresponding scan image can be obtained. At the same time, the mobile phone may display the confirmation window 1205 after obtaining the corresponding scan image through at least one scanning frame, until the mobile phone obtains the corresponding scan image through all the scanning frames or the mobile phone receives the user's operation on the control 1207 . Of course, in the above process, when multiple scan images are obtained through the same scan frame, the last scan image obtained through the scan frame can be determined as the corresponding scan image.

For example, the mobile phone determines the scanning frame a and the scanning frame b in response to the first sliding operation input by the user. In this way, in the preview image captured by the mobile phone, the card appears in the scanning frame a, but the card does not appear in the scanning frame b, then a scanned image of the card appearing in the scanning frame a can be obtained, at this time, a confirmation window 1205 can be displayed , after the user clicks the control 1206, the scan frame a and the scan frame b continue to be displayed. At this time, the mobile phone can capture the preview image again in response to the user operation. In the preview image captured again, a card appears in the scan frame b, and the scan frame can be obtained The scanned image corresponding to the card appears in b.

In addition, the scanned images obtained through the above-mentioned multiple scanned frames can be displayed on the same interface. Continuing from the above example, the scanned images corresponding to the scanning frame a and the scanning frame b can be displayed on the same interface. At the same time, the positions and sizes of the display of the multiple scan images are the same as those of the multiple scan borders. In this way, when the user needs to arrange multiple card scans on the same display interface, he can arrange the layout of each scan in advance (for example, determine the location and size of each scan). Reduce the running load required for arranging multiple scans on the mobile phone to ensure user experience.

In addition, in some embodiments, the function of scanning the card can also be integrated into other applications, for example, integrated into the camera APP, that is, the function of scanning the card and creating card information is realized in the camera APP. Then store the card information in the gallery in the form of pictures. In this way, when the mobile phone displays the interface 402 shown in (a) in Figure 14, it receives the user's operation on the gallery selection item 409, and displays the interface 1401 shown in (b) in Figure 14, and the interface 1401 displays There is card information collected by the camera APP. The user can select the target card information from the interface 1401, so that the mobile phone can display the interface 402 shown in (c) in FIG. 14 in response to the user's selection operation on the card information. The interface 402 includes card information selected by the user in the gallery. Afterwards, the mobile phone can also create a card note corresponding to the card information.

In addition, in some other embodiments, no matter whether the card information is obtained by scanning or searching the card information from the gallery, before creating the card note, it is also possible to identify whether the card information contains expiration information . For example, if the card information includes the reverse side of the ID card, the mobile phone can determine the valid period extracted from the reverse side of the ID card as the recognized period information. For another example, if the watermark information contained in the card information has a usage period in the watermark information, the mobile phone may determine the usage period in the watermark information as the identified expiration date information.

When the time limit information is identified from the card information, the mobile phone can remind the user of the time limit according to the time limit information, thereby reminding the user of the validity of the card note. In some embodiments, the form of the reminder can be a reminder inside the memo APP. Exemplarily, the corresponding time limit information is displayed at the card note, as shown in (a) in Figure 11, the card notes indicating the ID card all display corresponding time limit information. In some other embodiments, the form of the above-mentioned reminder can also be an alarm clock reminder or a calendar reminder, that is, when the system time of the mobile phone reaches the time point indicated by the deadline information, the alarm clock APP or the calendar APP is triggered to remind the due date . Understandably, the embodiment of the present application does not specifically limit the form of implementing the reminder.

In addition to manually creating card notes by users, card notes can also be created automatically. For example, after other applications create card information, mark the card information and notify the memo APP. The memo APP obtains the card information with the mark, and creates a card note based on the card information.

In addition, the method provided in the embodiment of the present application can be run in the memo APP of the mobile phone. As shown in Figure 15, the memo APP can include: data production function, data management function, data transfer function and artificial intelligence.

Among them, the data production function can be jointly realized by modules such as text editing, multimedia insertion, handwriting, and web page view. For the realization of the above-mentioned data generation function, reference may be made to the memo APP in the related art, which will not be repeated here.

In addition, the data management function includes modules such as replacement, data classification, data protection, and agency reminders. The above replacement module is used to indicate the function of transferring notes between different devices. For specific implementation, please refer to the memo APP in the related technology. The above-mentioned data protection module may include control modules such as recycle bin and data encryption. The above-mentioned data classification module is similar to the memo APP in the related art, the difference is that a new card-related folder is added to store notes marked as cards, so that when the user operates on the certificate option 105, the mobile phone can respond In this operation, the notes in the folder related to the card are displayed on the interface 106 . The agent reminding module includes time reminding, location reminding and repeated reminding. The time reminder can be used to realize the reminder of the expiration date of the card.

In addition, the data transfer function includes modules such as sharing, sharing applications and multi-terminal synchronization. Wherein, for the sharing module and the multi-terminal synchronization module, reference may be made to the Memorandum APP in the related art, which will not be repeated here. The printing in the sharing application module can be used to send the card notes to the connected printing device.

In addition, in addition to the cloud upload function, document scanning function, html recognition function, etc., the artificial intelligence function also includes the card scanning function, which is used to obtain the scanned image of the card.

As shown in Figure 16, the principle of the card scanning module to obtain the card scan image is as follows:

1601. Initialize camera activity (camera activity).

1602. Initialize a corresponding shadow process (Shadow Process).

1603. In response to an operation on the note creation interface, display an interface indicating image collection. For example, the scanning interface 701, the scanning interface 705, the interface 1201, the viewing interface 501, and the like are displayed.

In some embodiments, there is no necessary sequence between the

above steps

1602 and 1603 . Step 1603 may be implemented by camera fragments. Understandably, a camerafragment is an easy-to-use Android fragment that can be used to preview a camera view (ie, a preview image), and provides an API for triggering capture of the preview image. This API can be called by controls for instructing capture.

1604. Perform card detection and correction on the acquired preview image.

In some embodiments, the preview image may be preprocessed by an image rectification engine (dr engine). For example, the above preprocessing may include processing such as card detection, edge extraction, and rectangle correction on the card in the preview image.

Exemplarily, the dr engine can detect whether there is a card in the preview image, such as detecting whether a physical card appears within the scanning frame. When a card is detected, the card scan image for preview is obtained by preprocessing the preview image, which is also called a scan preview image. Exemplarily, the image area corresponding to the physical card (for example, referred to as the first image area) can be obtained from the preview image, and preprocessing such as rectangle correction is performed on the image area, so as to obtain the card scan image. Afterwards, the edge information of the scanned image of the card can be obtained and displayed. In this way, it is convenient for the user to preview the shape and position of the scanned card.

1605. Start the background sub-thread.

In some embodiments, when the mobile phone receives the user's operation on the control indicating to shoot, it can trigger the capture of a preview image as a stored image, such as stored image 1 and stored image 2 in the foregoing embodiments.

In some embodiments, the image stored in step 1604 (that is, the original preview image) may correspond to a preview scan image, also called a card image.

Afterwards, a sub-thread in the Shadow Process can be enabled from the image correction result view (dr resultview) to perform image processing on the card picture.

1606. Convert the image data of the card picture.

Exemplarily, the card picture is converted into image data in BGR format by Shadow Processes.

1607. Perform image processing on the converted card picture.

In some embodiments, the above-mentioned image processing may include processing such as shadow removal processing and image rectangle correction to improve the scanning effect. In addition, image processing may also include image sharpening and other processing to improve image display quality.

Of course, the above image processing can be realized by calling the corresponding algorithm from Shadow Proces, for example, the shadow removal process can be realized by calling the shadow removal algorithm from Shadow Proces.

1608. Save the processed card picture as a scanned picture of the card.

In some embodiments, through the

above steps

1604 and 1605, the scanned image of the card can be obtained, that is, the scanned image of the physical card. Afterwards, the scanned image can also be displayed in a corresponding preview interface. In the case of collecting multiple scans at the same time, for example, scanning the front and back of the ID card, multiple scans can be displayed in the same preview interface.

In addition, after receiving the user's operation on the manual correction control, the above scanning process also includes:

1609. Re-correct the stored image according to the user's operation.

In some embodiments, the dr engine retrieves the card picture from the stored image according to the user's card edge determination operation. After deshading the card image, perform rectangle correction again.

1610. Update data and refresh the interface. In some embodiments, the automatically generated scan image is replaced with the re-corrected card image, and the display is updated.

In addition, during the above scanning process, text recognition may be performed on the obtained scanned image, and the recognized text information may be stored in a specified field, for example, the attachment_detail field of the attachment information.

After completing the scanning of the card, you can also uninstall the Shadow Process and log out of the camera activity.

In some embodiments, as shown in Figure 17, the method provided in the embodiment of the present application may further include:

S201. Obtain corresponding card information, including a card picture and corresponding text.

S202, displaying card information on a preview interface.

In some embodiments, when the card information includes multiple scanned images, the sizes of the scanned images are adjusted to be the same. During the display of the scanned image in the preview interface, the mobile phone can respond to the user's operation, edit the display position and size of the scanned image in the preview interface, and add watermark information to the scanned image.

S203, in response to the user's operation on the control for instructing printing, print the content displayed in the preview interface.

In some embodiments, a print manager is invoked to effect printing. Exemplarily, after the mobile phone receives the user's operation on the control for instructing printing, it calls the print manager in the mobile phone application framework layer to implement. For example, create a print job by calling the PrintJob print class. Wherein, the print job includes print name, print document adapter and print attribute. The above print job can be used to instruct the print document adapter to print with the above print attributes.

In addition, when the mobile phone responds to the user's operation of clicking the card note, the card information in the card note can also be displayed on the preview interface. Afterwards, the mobile phone may also print the content displayed in the preview interface in response to the user's operation on the control for instructing printing.

In some embodiments, as shown in Figure 18, the method provided in the embodiment of the present application may further include:

S301. Obtain card information, including a card picture and corresponding text.

S302. Does the identification card information include expiration date information?

In some embodiments, when the memo APP starts running, it is acquired whether the mobile phone supports optical character recognition (Optical Character Recognition, OCR) capability. In the case of supporting the OCR capability, initialize the text detection engine. Certainly, in the case that the initialization of the text detection engine is successful, but the text detection engine has a recognition failure, the text detection engine can also be released in time.

Afterwards, as shown in FIG. 19 , the mobile phone may trigger the text detection engine to extract text in response to a specified extraction event. Exemplarily, each scan obtains a scan image, and it may be determined that an extraction event is generated. That is, every time a scanned image is scanned, the text detection engine will be triggered to extract text from the scanned image. As another example, when receiving an operation from the user indicating to save the card information, it may be determined that an extraction event is generated. That is, when receiving the user's instruction to save the card information, the text detection engine is triggered to extract text from the scanned image in the card information.

In some embodiments, triggering the text detection engine to perform text extraction may be: after detecting an extraction event, checking whether the text detection engine is initialized. In the case of initialization, character extraction is performed. And from the extracted text, it is judged whether there is deadline information. In addition, the text detection engine can also be released when the text extraction is completed.

S303. If there is deadline information, set an expiration reminder.

In some embodiments, the above-mentioned period information may also be referred to as the validity period of the card information. When the time limit information is identified, a reminder is set for the card information, which is used to remind the expiration time of the card note. For example, the mobile phone can perform format verification on the identified validity period. In addition, the format of the validity period can also be converted into long data. Afterwards, the AlarmManager can be called, combined with the validity period after the format conversion, the method of setting the alarm clock (setAlarmClock) can be used to set the alarm.

The text detection engine can also be freed in cases where the term information is not extracted.
