     BACKGROUND 
     With the continuous improvement of intelligence of electronic devices, applications in the electronic devices have more and more functions. 
     In the related art, a user may scan a quick response code through a quick response code scanning function of some applications to complete some operations, to meet user needs. For example, the user may scan a payment quick response code through a quick response code scanning function in a payment application to complete a payment operation, or the user may scan a quick response code of another user through a quick response code scanning function in a communication application to complete a friend adding operation. 
     However, a quick response code must be compiled according to predetermined rules and the quick response code needs to have a carrier before it can be presented to a user (that is, the quick response code needs to be displayed on a screen or printed on paper). As a result, a process of completing an operation by scanning a quick response code is not flexible enough.

     DETAILED DESCRIPTION 
     The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     In this specification, the term “and/or” is merely an association relationship that describes associated objects, and represents that there may be three relationships. For example, A and/or B may represent three cases: only A exists, both A and B exist, and only B exists. A character “/” in this specification indicates an “or” relationship between associated objects. For example, A/B indicates A or B. 
     In this specification, the terms such as “first” and “second” are used to distinguish between different objects, but are not used to describe a particular sequence of the objects. For example, a first image, a second image, and the like are used to distinguish between different images, but are not used to describe a particular sequence of the images. 
     In the embodiments of the present disclosure, the word such as “example” or “for example” is used to represent giving an example, an illustration, or a description. Any embodiment or design scheme described as “exemplary” or “for example” in the embodiments of the present disclosure should not be construed as being more preferred or advantageous than other embodiments or design schemes. To be precise, the use of the term such as “exemplary” or “for example” is intended to present a related concept in a specific manner. 
     In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of “a plurality of” means two or more. For example, a plurality of elements mean two or more elements. 
     According to an aspect, an embodiment of the present disclosure provides a note information display method and an electronic device. The electronic device may collect a first image (the first image includes an image of a first object), identify the first image to obtain first information (the first information is feature information of the first object), and then send the first information to a server, so that the server searches for the first information in the server, and sends first note information corresponding to the first information to the electronic device when the first information is found, that is, the electronic device receives the first note information sent by the server and displays the first note information. In this solution, a user may trigger feature information of an object and note information to be prestored in a server. Therefore, when the user needs to process a specific object, the user may trigger the electronic device to obtain note information based on feature information of the object, so that the user can process the object based on the note information. In this way, in this embodiment of the present disclosure, note information used to process an object can be directly obtained based on the object without using another object (for example, a quick response code). Therefore, flexibility of obtaining note information can be improved, thereby improving flexibility of processing an object. 
     According to another aspect, an embodiment of the present disclosure provides a note information sending method and an electronic device. The electronic device may collect a first target image (the first target image includes an image of a first object), identify the first target image to obtain first information (the first information is feature information of the first object), then receive first note information entered by a user, and send target information (the target information includes the first information and the first note information corresponding to the first information) to a server. In this solution, a user may trigger the electronic device to send a note and endow the note with information according to an actual usage requirement of the user. Therefore, there is no need to perform an operation as in the related art: obtaining a quick response code of first note information by compiling the quick response code according to predetermined rules, thereby simplifying a process of making a note. In addition, in a process of making a note, privacy and security of note information can be guaranteed by setting a public manner of the note information. 
     The electronic device in the embodiments of the present disclosure may be an electronic device with an operating system. The operating system may be an Android (Android) operating system, or may be an iOS operating system or another possible operating system, which is not specifically limited in the embodiments of the present disclosure. 
     The following uses the Android operating system as an example to introduce a software environment applicable to the note information display method and the note information sending method provided in the embodiments of the present disclosure. 
       FIG. 1  is a schematic architectural diagram of a possible Android operating system according to an embodiment of the present disclosure. In  FIG. 1 , the architecture of the Android operating system includes 4 layers, which are an application layer, an application framework layer, a system runtime library layer, and a kernel layer (which may be specifically a Linux kernel layer). 
     The application layer includes various applications in the Android operating system (that include system applications and third-party applications). 
     The application framework layer is an application framework, and a developer may develop some applications based on the application framework layer following a rule of developing the application framework. 
     The system runtime library layer includes a library (also referred to as a system library) and a running environment of the Android operating system. The library mainly provides various resources needed by the Android operating system. The running environment of the Android operating system is used for providing a software environment for the Android operating system. 
     The kernel layer is the operating system layer of the Android operating system and belongs to the lowest layer of software hierarchy of the Android operating system. The kernel layer provides core system services and hardware-related drivers for the Android operating system based on the Linux kernel. 
     The Android operating system is used as an example. In the embodiments of the present disclosure, based on the system architecture of the Android operating system shown in  FIG. 1 , developers can develop software programs that implement the note information display method and the note information sending method provided in the embodiments of the present disclosure, so that the note information display method and the note information sending method can be performed based on the Android operating system shown in  FIG. 1 . That is, by running the software program in the Android operating system, the processor or the electronic device can implement the note information display method or the note information sending method provided in the embodiments of the present disclosure. 
     The electronic device in the embodiments of the present disclosure may be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device may be a mobile phone, a tablet computer, a laptop computer, a palmtop computer, an in-vehicle terminal, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, or a personal digital assistant (personal digital assistant, PDA). The non-mobile electronic device may be a personal computer (personal computer, PC), a television (television, TV), an automated teller machine or a self-service machine. This is not specifically limited in the embodiments of the present disclosure. 
     The executor of the note information display method and the note information sending method provided in the embodiments of the present disclosure may be the foregoing electronic device, or may be a functional module and/or a functional entity that can implement the note information display method and the note information sending method in the electronic device. This may be specifically determined based on an actual usage requirement and is not limited in the embodiments of the present disclosure. The following uses an electronic device as an example to describe the note information display method and the note information sending method provided in the embodiments of the present disclosure. 
     In the embodiments of the present disclosure, when a user needs to process a specific object but does not know how to process the object, the user may trigger the electronic device (for example, a first electronic device in the following embodiment) to collect feature information of the object, and send the feature information of the object to a server. The server searches for the feature information in the server and sends note information corresponding to the feature information to the electronic device after the feature information is found. Then, after receiving the note information sent by the server, the electronic device may display the note information, so that the user can process the object based on the note information. In other words, when the user needs to process a specific object, the user may trigger a specific electronic device to obtain note information used to process the object through feature information of the object, so that the user can process the object based on the note information. In this way, in the embodiments of the present disclosure, note information used to process an object can be directly obtained based on the object without using another object (for example, a quick response code). Therefore, flexibility of obtaining note information can be improved, thereby improving flexibility of processing an object. 
     The foregoing note information may be pre-stored in a server by triggering another electronic device (for example, a second electronic device in the following embodiments) by a user. A method for the user to trigger the another electronic device to prestore the note information is described in detail in the following embodiments, and details are not repeated herein. 
     It should be noted that, the electronic device provided in the embodiments of the present disclosure may support a video code protocol. Specifically, when the electronic device supports a video code protocol, a camera application of the electronic device may include a video code mode. In the video code mode, the electronic device may obtain note information used to process a specific object. Specifically, the electronic device may perform the method in the embodiments of the present disclosure to obtain note information used to process a specific object. 
     In the embodiments of the present disclosure, the camera application of the electronic device may further include a video mode, a photo mode, a panorama mode, and modes supported in other possible scenarios. In the video mode, the electronic device may perform a video shooting operation; in the photo mode, the electronic device may perform a photo shooting operation; and in the panorama mode, the electronic device may perform a panorama shooting operation. 
     In the embodiments of the present disclosure, two processes may be included: one process is a process of displaying a note, and the other process is a process of making a note. To distinguish the electronic device in one of the processes from the electronic device in the other process, in the following embodiments, the electronic device in the process of displaying a note is referred to as a first electronic device, and the electronic device in the process of making a note is referred to as a second electronic device. 
     In the embodiments of the present disclosure, the foregoing first electronic device and second electronic device may be a same electronic device, or may be different electronic devices. This may be specifically determined according to an actual usage requirement, and is not limited in the embodiments of the present disclosure. 
     The following uses examples to describe the foregoing process of displaying a note (namely, the note information display method provided in the embodiments of the present disclosure) below with reference to the accompanying drawings. 
     As shown in  FIG. 2 , an embodiment of the present disclosure provides a note information display method. The method may be applied to the foregoing first electronic device, and may include the following steps S 201  to S 205 . 
     S 201 : The first electronic device collects a first image. 
     The foregoing first image may include an image of a first object. 
     Optionally, in this embodiment of the present disclosure, the first electronic device may collect the image of the first object by using a camera, to obtain the first image. 
     It should be noted that, in this embodiment of the present disclosure, before the first electronic device collects the first image, the user may trigger the first electronic device to determine the first object. Specifically, in this embodiment of the present disclosure, the user may circle (for example, tap) the first object in a preview screen of a camera application of the first electronic device to trigger the first electronic device to determine the first object. 
     Optionally, in this embodiment of the present disclosure, the foregoing step S 201  may be specifically implemented by using the following step S 201   a.    
     S 201   a : The first electronic device collects the first image when a camera application of the first electronic device is in a video code mode. 
     It may be understood that, in this embodiment of the present disclosure, the foregoing first object may be an object that the user triggers the first electronic device to select in the preview screen of the camera application of the first electronic device when the camera application of the first electronic device is in the video code mode. For example, assuming that the preview screen of the camera application includes objects such as a “cup”, a “human”, and the like, the user may trigger the first electronic device to select any one of the “cup” or the “human” as the first object. 
     S 202 : The first electronic device identifies the first image to obtain first information. 
     The foregoing first information may be feature information of the first object. 
     In this embodiment of the present disclosure, after the first electronic device collects the image of the first object to obtain the first image, the first electronic device may identify the first image by using an image recognition algorithm, to obtain the feature information of the first object, namely, the first information. The image recognition algorithm may be any possible image recognition algorithm such as a face recognition algorithm (used to identify a face image) or a clustering analysis algorithm (used to identify an object image), which may be specifically determined according to an actual usage requirement, and is not limited in the embodiments of the present disclosure. 
     Optionally, in this embodiment of the present disclosure, the foregoing feature information of the first object may include at least one of color information, dimension information, and shape information of the first object. The color information may include color types, a proportion of each color, and the like; the dimension information may include a length, a width, a height, and the like; and the shape information may include shape types, a bending degree, and the like. This may be specifically determined according to an actual usage requirement, and is not limited in the embodiments of the present disclosure. 
     S 203 : The first electronic device sends the first information to a server. 
     In this embodiment of the present disclosure, after the first electronic device sends the first information to the server, the server may receive the first information. 
     It should be noted that, in this embodiment of the present disclosure, feature information of an object and note information used for a user to process the object may be prestored in a server. Specifically, a plurality of pieces of information may be prestored in the server. Each piece of information includes feature information of an object and note information used for a user to process the object, that is, feature information of each object and note information used for a user to process the object are stored in the server in a corresponding manner. In this way, when the server receives feature information, sent by a first electronic device, of a specific object, the server may search for the feature information in the server. If the server finds the feature information, the server may send note information stored with the feature information in a corresponding manner to the first electronic device, so that after the first electronic device displays the note information, the user can process the object based on the note information. 
     In this embodiment of the present disclosure, after the server receives the foregoing first information, the server may find whether there is the first information in the server. 
     It should be noted that, in this embodiment of the present disclosure, if the server finds the first information in the server, the first electronic device may continue to perform the following step S 204 . If the server does not find the first information in the server, the server may not send any message to the first electronic device. In this way, in a preset time period within which the first electronic device sends the first information, if the first electronic device does not receive any message, after the preset time period, the first electronic device may prompt the user that note information corresponding to the first object is not found; or, the server may send a response message (used to indicate that the note information corresponding to the first object is not found in the server) to the first electronic device. In this way, after the first electronic device receives the response message, the first electronic device may prompt the user that the note information corresponding to the first object is not found. 
     In this embodiment of the present disclosure, when the server finds the first information in the server, the server may send first note information corresponding to the first information to the first electronic device. 
     S 204 : The first electronic device receives first note information that corresponds to the first information and that is sent by the server. 
     In this embodiment of the present disclosure, after the first electronic device sends the first information, the server may search for the first information in the server. When the server finds the first information in the server, the server may send first note information that corresponds to the first information and that is sent by the server to the first electronic device, that is, the first electronic device may receive the first note information sent by the server. 
     It should be noted that, the foregoing first information may be feature information, prestored in the server, of the first object. 
     Optionally, in this embodiment of the present disclosure, the foregoing first note information may be information in any possible form, such as text information, picture information, video information, link information, or voice information. This may be specifically determined according to an actual usage requirement, and is not limited in the embodiments of the present disclosure. 
     S 205 : The first electronic device displays the first note information. 
     The foregoing first note information may be used to process the first object. 
     In this embodiment of the present disclosure, after the first electronic device receives the first note information sent by the server, the first electronic device may display the first note information, so that the user can process the first object based on the first note information. 
     Optionally, in this embodiment of the present disclosure, the foregoing first note information may be displayed on a display screen of the first electronic device at any position. This may be specifically determined according to an actual usage requirement, and is not limited in the embodiments of the present disclosure. 
     Optionally, in this embodiment of the present disclosure, before the first electronic device displays the first note information, the first electronic device may display one piece of prompt information, which is used to prompt the user that note information (or may be referred to as a note code) corresponding to the first object is found and whether the note information needs to be displayed. In addition, when the user triggers the first electronic device to display the first note information, the first electronic device may display the first note information, and cancel display of the prompt information; or, when the user does not trigger or trigger the first electronic device to not to display the first note information, the first electronic device may not display the first note information, and cancel display of the prompt information. 
     In this embodiment of the present disclosure, the user may trigger feature information of an object and note information to be prestored in a server. Therefore, when the user needs to process a specific object, the user may trigger the first electronic device to obtain note information based on feature information of the object, so that the user can process the object based on the note information. In this way, in the embodiments of the present disclosure, note information used to process an object can be directly obtained based on the object without using another object (for example, a quick response code). Therefore, flexibility of obtaining note information can be improved, thereby improving flexibility of processing an object. 
     Optionally, in this embodiment of the present disclosure, if the first note information is encrypted note information, before the first electronic device displays the first note information, the first electronic device may first display prompt information used to prompt the user to enter a password, to decrypt the first note information. 
     For example, with reference to  FIG. 2 , as shown in  FIG. 3 , before the foregoing step S 205 , the note information display method provided in this embodiment of the present disclosure may further include the following step S 206 . In addition, optionally, the foregoing step S 205  may be specifically implemented by using the following step S 205   a.    
     S 206 : The first electronic device displays first prompt information. 
     The foregoing first prompt information may be used to prompt the user to enter password information. 
     In this embodiment of the present disclosure, if the first note information is encrypted note information, after the first electronic device receives the first note information sent by the server, the first electronic device may first display the first prompt information used to prompt the user to enter password information, to decrypt the first note information. 
     Optionally, in this embodiment of the present disclosure, the foregoing first prompt information may include first prompt content and a first input area. The first prompt content may be used to prompt the user that the first note information is encrypted and password information needs to be entered for decryption. The first input area may be used for the user to enter the password information. 
     For example, as shown in  FIG. 4 , the foregoing first prompt content may be “The note information is encrypted, and please enter the password.” (As shown by  41  in  FIG. 4 ). The user may enter password information in the first input area (as shown by  42  in  FIG. 4 ), to decrypt the first note information. 
     Optionally, in this embodiment of the present disclosure, the foregoing first prompt information may further include a first help option. The first help option may be used to help the user to obtain password information used to encrypt the first note information. Specifically, the first help option may be used to help the user to obtain the password information used to encrypt the first note information when the user does not know the password information. 
     For example, as shown in  FIG. 4 , when the user does not know the password information used to encrypt the first note information, the user may tap the first help option (as shown by  43  in  FIG. 4 ) to trigger the first electronic device to send user information of a user of the first electronic device to a target user. 
     In this embodiment of the present disclosure, it is assumed that a user that needs to process the first object is referred to as a user  1 , an electronic device of the user  1  is referred to as an electronic device  1 , and an electronic device of the target user is referred to as an electronic device  2 . After the electronic device  2  receives user information of the user  1  sent by the electronic device  1 , if the target user allows the user  1  to access note information (namely, the foregoing first note information) corresponding to the first object, the target user may trigger the electronic device  2  to send password information to the electronic device  1 , that is, the electronic device  1  may receive the password information (namely, password information used to decrypt the first note information) sent by the electronic device  2 , so that the electronic device  1  may display the first note information after the first note information is decrypted. If the target user does not allow the user  1  to access the note information (namely, the foregoing first note information) corresponding to the first object, the target user may trigger the electronic device  2  to send an access reject message to the electronic device  1 , that is, the electronic device  1  may receive the access reject message, so that the electronic device may prompt the user, based on the access reject message, that the user have no permission to access the first note information. 
     It should be noted that, the foregoing target user may be a user that triggers an electronic device to make a note. Specifically, for a process of making a note, reference may be made to the following description of a process of making a note. To avoid repetition, details are not described herein. 
     S 205   a : The first electronic device displays the first note information when first password information entered by a user is the same as first target password information. 
     The foregoing first target password information may be password information used to encrypt the foregoing first note information. 
     In this embodiment of the present disclosure, after the user enters password information (namely, the first password information), the first electronic device may determine whether the first password information entered by the user is the same as password information (namely, the first target password information) used to encrypt the foregoing first note information; and if the first password information is the same as the first target password information, the first electronic device may display the first note information; or if the first password information is different from the first target password information, the first electronic device may prompt the user that the entered password information is incorrect. 
     In this embodiment of the present disclosure, when the first note information is encrypted, before displaying the first note information, the first electronic device may first prompt the user to enter password information, and display the first note information when the password information entered by the user is correct, so that security of the first note information can be improved, and leakage of the first note information can be prevented. In addition, when the first note information involves private information of the user, leakage of the private information of the user can be prevented. 
     Optionally, in this embodiment of the present disclosure, before the first electronic device collects the first image, the first electronic device may send location information of a location of a first object to a server. When the server finds the location information in the server, the server may send an instruction to an electronic device, to instruct the electronic device to collect an image of the first object. 
     For example, with reference to  FIG. 2 , as shown in  FIG. 5 , before the foregoing step S 201 , the note information display method provided in this embodiment of the present disclosure may further include the following step S 207 . In addition, optionally, the foregoing step S 201  may be implemented by using the following step S 201   a.    
     S 207 : The first electronic device sends first location information of a location of the first object to the server. 
     The foregoing first location information may be used to indicate a geographical location where the first object is located when the first electronic device obtains the first location information. 
     Optionally, in this embodiment of the present disclosure, location information of the first object may be determined based on location information of the first electronic device. Specifically, the location information of the first object may be location information of a geographical location the first electronic device. In other words, the first electronic device may obtain location information of a geographical location of the first object by obtaining the location information of the geographical location of the first electronic device. 
     In this embodiment of the present disclosure, when the user triggers the first electronic device to run a camera application; or, when the user triggers the camera application in the first electronic device to switch to a video code mode, a location detection function may be enabled on the first electronic device and used to detect a current location of the first electronic device. In addition, after the user triggers the first electronic device to determine the first object, the first electronic device may use location information of a current geographical location of the first electronic device as location information (namely, the first location information) of the first object and send the location information to the server. 
     In this embodiment of the present disclosure, the foregoing first location information may be understood as latitude and longitude information of a location of the first object, namely, latitude and longitude information of a location of the first electronic device. 
     In this embodiment of the present disclosure, after the first electronic device sends the first location information to the server, the server may receive the first location information. 
     It should be noted that, in this embodiment of the present disclosure, location information of an object may be prestored in the server. Specifically, each piece of information in the foregoing plurality of pieces of information prestored in the server may include not only feature information of an object and note information used for a user to process the object, but also location information of the object, that is, feature information of each object, note information used for a user to process the object, and location information of the object are stored in the server in a corresponding manner. In this way, when the server receives location information, sent by the first electronic device, of a specific object, the server may search for the location information in the server. If the server finds the location information, the server may send a first instruction to the first electronic device to instruct the first electronic device to collect an image of the object and identify the image, so as to obtain feature information of the object. After the first electronic device obtains the feature information of the object, the first electronic device may send the feature information of the object to the server. In this way, when the server receives the feature information, sent by the first electronic device, of the object, the server may search, in the server, for the feature information from feature information corresponding to the location information. If the server finds the feature information, the server may send note information stored with the feature information in a corresponding manner to the first electronic device, so that after the first electronic device displays the note information, the user can process the object based on the note information. 
     In this embodiment of the present disclosure, after the server receives the foregoing first location information, the server may search for the first location information in the server. 
     It should be noted that, in this embodiment of the present disclosure, if the server finds the first location information in the server, the server may send a first instruction to the first electronic device. If the server does not find the first location information in the server, the server may not send any message to the first electronic device. In this way, in a preset time period within which the first electronic device sends the first location information, if the first electronic device does not receive any message, after the preset time period, the first electronic device may prompt the user to reselect an object; or, the server may send a response message (used to indicate that location information in accordance with location information of the first object is not found in the server) to the first electronic device. In this way, after the first electronic device receives the response message, the first electronic device may prompt the user to reselect an object. It may be understood that, in this embodiment of the present disclosure, after the user retriggers the first electronic device to determine the first object, the first electronic device may return to the foregoing step S 207  to perform this step. 
     In this embodiment of the present disclosure, when the server finds the first location information, the server may send the first instruction to the first electronic device. The first electronic device may receive the first instruction. 
     It may be understood that, the foregoing first instruction is sent by the server when the server finds the first location information in the server. 
     S 201   a : When a first instruction that corresponds to the first location information and that is sent by the server is received, the first electronic device collects the first image based on the first instruction. 
     In this embodiment of the present disclosure, after the first electronic device receives the first instruction sent by the server, the first electronic device may start to collect an image of the first object based on the first instruction, to obtain the first image. 
     In this embodiment of the present disclosure, the first electronic device may start to collect the image of the first object after receiving the first instruction sent by the server, that is, the first electronic device starts to collect the image of the first object only when location information of a current location of the first object is prestored in the server. Therefore, the first electronic device can be prevented from performing unnecessary operations, thereby reducing power consumption of the first electronic device. 
     The following further uses examples to describe the foregoing process of making a note (namely, the note information sending method provided in the embodiments of the present disclosure) below with reference to the accompanying drawings. 
     As shown in  FIG. 6 , an embodiment of the present disclosure provides a note information sending method. The method may be applied to the second electronic device, and may include the following steps S 301  to S 304 . 
     S 301 : The second electronic device collects a first target image. 
     The foregoing first target image includes an image of a first object. 
     Optionally, in this embodiment of the present disclosure, the foregoing step S 301  may be specifically implemented by using the following step S 301   a.    
     S 301   a : The second electronic device collects the first target image when a camera application of the second electronic device is in a video code mode. 
     It may be understood that, the foregoing first target image may be an image of a first object in a preview screen of a camera application of the second electronic device when the camera application of the second electronic device is in a video code mode. 
     Optionally, in this embodiment of the present disclosure, the second electronic device may collect the image of the first object by using a camera, to obtain the first target image. 
     It may be understood that, in this embodiment of the present disclosure, the foregoing first image is an image, collected in the process of displaying a note, of the first object. The foregoing first target image is an image, collected in the process of making a note, of the first object. 
     It should be noted that, in this embodiment of the present disclosure, before the second electronic device collects the first target image, the target user needs to trigger the second electronic device to determine the first object. Specifically, in this embodiment of the present disclosure, the target user may circle (for example, tap) the first object in a preview screen of the camera application of the second electronic device to trigger the second electronic device to determine the first object. 
     For example,  FIG. 7  is a schematic diagram of a preview screen displayed when the camera application of the second electronic device is in a video code mode. The preview screen includes a “computer” (as shown by  71  in  FIG. 7 ) and a “cup” (as shown by  72  in  FIG. 7 ). The target user may tap the “cup” to trigger the second electronic device to determine the “cup” as the first object, or the target user may tap the “computer” to trigger the second electronic device to determine the “computer” as the first object. As shown in  FIG. 7 , in this embodiment of the present disclosure, that the “cup” is the first object is used as an example. After the target user taps the “cup”, a select box may be displayed around the “cup”, to prompt the target user that a selected object is the “cup” (as shown by  73  in  FIG. 7 ). Further, after the target user triggers the second electronic device to determine the first object, the second electronic device may collect the image of the first object, to obtain the first target image. 
     For details about other descriptions of the foregoing step S 301 , reference may be made to related description of the step S 201  in the foregoing embodiment. To avoid repetition, details are not described herein again. 
     S 302 : The second electronic device identifies the first target image to obtain first information. 
     The foregoing first information is feature information of the first object. 
     In this embodiment of the present disclosure, after the second electronic device collects the image of the first object to obtain the first target image, the second electronic device may identify the first target image by using an image recognition algorithm, to obtain the feature information of the first object, namely, the first information. For specific description of the image recognition algorithm, reference may be made to related description of the image recognition algorithm in the foregoing step S 202 , and details are not described herein again. 
     The following further uses examples to describe the foregoing step S 302  with reference to  FIG. 8 . 
     For example, as shown in  FIG. 8 , assuming that the first object is a “cup” (as shown by  81  in  FIG. 8 ), the second electronic device may identify the “cup” to obtain feature information of the “cup”, and display the feature information (namely, the first information) and an image of the “cup” (as shown by  82  in  FIG. 8 ) in a current interface at a lower right corner. For example, the feature information of the “cup” obtained by the second electronic device is: Height: 5.7 cm; Color: gray; and Accessory: spoon. 
     Optionally, in this embodiment of the present disclosure, after the second electronic device obtains the feature information of the first object, namely, the foregoing first information, the second electronic device may display the first information in a current interface, so that the target user can view the feature information of the first object. 
     For details about other descriptions of the foregoing step S 302 , reference may be made to related description of the step S 202  in the foregoing embodiment. To avoid repetition, details are not described herein again. 
     S 303 : The second electronic device receives first note information entered by a user. 
     S 304 : The second electronic device sends target information to a server. 
     The foregoing target information includes the first information and the first note information corresponding to the first information. 
     The following further uses examples to describe a process in which the target user triggers the foregoing first note information to be entered with reference to  FIG. 9 . 
     For example, it is assumed that the foregoing first object is the “cup”.  FIG. 9  is a schematic diagram of an interface displayed on the second electronic device and used for the first note information to be entered. After the second electronic device obtains the feature information of the “cup”, as shown in  FIG. 9( a ) , the second electronic device may display the feature information (namely, the first information) and an image of the “cup” (as shown by  91  in  FIG. 9( a ) ) in the interface at a lower right corner. In addition, the second electronic device may display a plurality of note information types (as shown by  92  in  FIG. 9( a ) ) for the target user to select a type of the first note information. When the target user selects a text type from the plurality of note information types, the second electronic device may determine the type of the first note information as a text type. In this case, the second electronic device may display an information input area (as shown by  93  in  FIG. 9( b ) ) for the target user to enter content of the first note information. As shown in  FIG. 9( b ) , the target user may enter the content of the first note information in the information input area. For example, the content of the first note information may be “Hi, this is a cup of milk tea. I brought it over in the morning. Seeing that you are not in your seat, remember to drink it while it is still hot, R.” shown in  FIG. 9( b ) . Further, after the target user enters the content of the first note information in the information input area, the target user may tap a “Complete” control (as shown by  94  in  FIG. 9( b ) ) shown in  FIG. 9( b )  to trigger the second electronic device to send the first note information and the foregoing first information to the server. 
     In this embodiment of the present disclosure, after the second electronic device sends the foregoing first note information and the feature information of the first object to the server, the server may store the first note information and the feature information of the first object. If the user needs to obtain the first note information, the user may trigger the first electronic device to send the feature information of the first object to the server, so that after the server receives the feature information of the first object, the server may send note information corresponding to the first object, namely, the first note information, to the user. 
     It may be understood that, in this embodiment of the present disclosure, in the foregoing process of making a note, note information triggered to be entered for a specific object by the target user is note information, for the object, received by the first electronic device from the server in the process of displaying a note. 
     In this embodiment of the present disclosure, after the second electronic device obtains the first information and the first note information triggered to be entered by the target user, the second electronic device may send the first information and the first note information to the server as target information. Therefore, after the server receives the target information, the target information may be stored in the server. In this way, a process in which the feature information of the first object and the first note information used to process the first object are prestored in the server may be completed, that is, the process of making a note may be completed. 
     Optionally, in this embodiment of the present disclosure, the foregoing target information may further include third information. The third information may be used to indicate a public manner of the foregoing first note information. In other words, the public manner of the first note information may also be prestored in the server. The third information may be triggered to be set by the target user. 
     Optionally, the public manner of the foregoing first note information may be any one of the following: public, public after encryption, hidden after encryption, and authorization required after encryption. 
     In this embodiment of the present disclosure, when the public manner of the foregoing first note information is being public, any user can view the first note information. When the public manner of the foregoing first note information is being public after encryption, any user needs to enter password information to view the first note information. When the public manner of the foregoing first note information is being hidden after encryption, only the target user can view the first note information. When the public manner of the foregoing first note information is being authorization required after encryption, only a user who is authorized by the target user can view the first note information. 
     It should be noted that, in this embodiment of the present disclosure, when the target user triggers the public manner of the first note information to be set as being public after encryption, the user may trigger the first electronic device to perform the foregoing step S 205  when the user needs to display the first note information. 
     The following further uses examples to describe, with reference to  FIG. 10 , a process in which the target user triggers a public manner of the first note information to be set. 
     For example, as shown in  FIG. 10 , after the target user taps the “Complete” control shown by  94  in  FIG. 9 , the second electronic device may further display prompt information and a plurality of public manners that are shown by  101  in  FIG. 10 . The prompt information may be used to prompt the target user to select a public manner of the first note information according to an actual usage requirement, so that the target user can select a required public manner from the plurality of public manners, and the second electronic device may further determine the public manner selected by the target user as the public manner of the first note information. It may be understood that, in this embodiment of the present disclosure, as shown in  FIG. 10 , when the second electronic device displays the prompt information and the plurality of public manners (that is, in the process in which the target user triggers the public manner of the first note information to be set) shown by  101  in  FIG. 10 , the second electronic device may display the feature information of the first object (namely, the first information) and the image of the first object at a lower right corner. 
     Optionally, in this embodiment of the present disclosure, the foregoing target information may further include first location information of a location of the first object. 
     Optionally, in this embodiment of the present disclosure, before the foregoing step S 301  is performed, the target user may first trigger the second electronic device to prestore location information of the first object in the server. 
     In this embodiment of the present disclosure, after the second electronic device sends the first location information to the server, the server may store the first location information in the server, so that when the user needs to obtain the first note information, the server judges the first location information sent by the second electronic device when being triggered by the user. 
     In this embodiment of the present disclosure, a target user may trigger the second electronic device to send a note and endow the note with information according to an actual usage requirement of the user. Therefore, there is no need to perform an operation as in the related art: obtaining a quick response code of first note information by compiling the quick response code according to predetermined rules, thereby simplifying a process of making a note. In addition, in a process of making a note, privacy and security of note information can be guaranteed by setting a public manner of the note information. 
     Optionally, in this embodiment of the present disclosure, before the user triggers the first electronic device to perform the process of displaying a note (namely, the note information display method provided in the embodiments of the present disclosure), the user may first trigger the second electronic device to perform the process of making a note (namely, the note information sending method provided in the embodiments of the present disclosure).

     The user input unit  107  can be configured to receive entered number or character information, and generate key signal input related to user settings and function control of the electronic device. Specifically, the user input unit  107  includes a touch panel  1071  and another input device  1072 . The touch panel  1071  is also referred to as a touchscreen, and may collect a touch operation of the user on or near the touch panel  1071  (for example, an operation performed on or near the touch panel  1071  by the user by using any appropriate object or accessory such as a finger or a stylus). The touch panel  1071  may include two parts: a touch detection apparatus and a touch controller. The touch detection apparatus detects a touch position of the user, detects a signal brought by the touch operation, and sends the signal to the touch controller. The touch controller receives touch information from the touch detection apparatus, converts the touch information into touch point coordinates, sends the touch point coordinates to a processor  110 , and receives and executes a command sent by the processor  110 . In addition, the touch panel  1071  may be of a resistive type, a capacitive type, an infrared type, a surface acoustic wave type, or the like. The user input unit  107  may include another input device  1072  in addition to the touch panel  1071 . Specifically, the another input device  1072  may include but is not limited to a physical keyboard, function keys (for example, a volume control key and an on/off key), a trackball, a mouse, and a joystick. Details are not described herein. 
     Further, the touch panel  1071  can cover the display panel  1061 . When detecting a touch operation on or near the touch panel  1071 , the touch panel  1071  transmits the touch operation to the processor  110  to determine a type of a touch event. Then, the processor  110  provides corresponding visual output on the display panel  1061  based on the type of the touch event. Although in  FIG. 14 , the touch panel  1071  and the display panel  1061  are configured as two independent components to implement input and output functions of the electronic device, in some embodiments, the touch panel  1071  and the display panel  1061  can be integrated to implement the input and output functions of the electronic device. Details are not limited herein. 
     The interface unit  108  is an interface for connecting an external apparatus and the electronic device  100 .
