The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The image acquisition method provided by the embodiment of the application is described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.
The image acquisition method provided by the application can be suitable for acquiring the application scene of the image corresponding to the display interface in the second electronic device by using the first electronic device. The second electronic device may be a device provided with a display screen, such as a computer, a television, etc., and the first electronic device may be a device with photographing and display functions, such as a mobile phone, a tablet computer, etc.
According to the above application scenario, the image acquisition method provided in the embodiment of the present application is described in detail below with reference to fig. 1 to 4. It should be noted that, in the image capturing method provided in the embodiment of the present application, the execution subject may be an image capturing device, or a control module in the image capturing device for executing the image capturing method, where the image capturing device may be integrated in the first electronic apparatus. In the embodiment of the present application, an image acquisition device executes an image acquisition method as an example, and the image acquisition method provided in the embodiment of the present application is described.
Fig. 1 is a flowchart illustrating an image acquisition method according to an exemplary embodiment.
As shown in fig. 1, the image acquisition method may include the steps of:
step 110, acquiring a first image acquired by a camera of a first electronic device.
The first image in the embodiment of the application may be an environmental image acquired by a camera of the first electronic device. Specifically, the first image may be a dynamic picture acquired by the camera in real time, or may be a still image acquired by the camera currently, which is not limited herein.
In one specific example, as shown in fig. 2, if the user wants to obtain the information 221 displayed in the computer 22 through the mobile phone 21, the mobile phone 21 can obtain an image including the display screen of the computer 22 by starting the mobile phone 21 to take a photo of APP (application program) and aligning the camera of the mobile phone 21 with the display screen of the computer 22.
Step 120, identifying an acquisition object of the first image.
Here, the acquisition object may be an object contained in the first image, for example, in the case where the device display screen is contained in the first image, the acquisition object may be the device display screen. Specifically, a preset object recognition algorithm may be adopted, and the acquired objects in the first image are recognized by using feature information corresponding to each acquired object, where the object recognition algorithm includes, but is not limited to, a saliency recognition algorithm, and the like.
The method includes the steps of detecting whether the environment image collected by the camera of the first electronic device contains feature information such as a display screen frame and a menu task bar in real time, if the environment image contains the feature information, determining that the collected object is a device display screen, and if the environment image does not contain the feature information, determining that the collected object is not the device display screen.
And 130, under the condition that the acquisition object of the first image is a device display screen, establishing screen projection connection with the second electronic device, and displaying a display interface of the second electronic device.
Here, the second electronic device may be a device that is connected to the first electronic device in a screen-casting manner, including but not limited to a wireless connection.
The method for establishing the screen-throwing connection between the first electronic device and the second electronic device includes, but is not limited to, connection through a wifi direct connection mode, or intercommunication connection of information through a router under the same local area network, or a combination mode of the two connection modes, namely, connection through the wifi direct connection mode is preferred, and if connection errors or packet loss rate reaches a preset threshold value during connection, the connection is switched to intercommunication connection of information through the router in the local area network where the first electronic device is located.
In addition, the connection response mechanism between the first electronic device and the second electronic device includes, but is not limited to, setting a device white list in the second electronic device, that is, when a connection request sent by a device in the device white list is received, the connection request can be automatically responded, and the connection request with the device is granted, so that a connection is established. In order to ensure security and uniqueness, the device names in the whitelist may be generated by CID (Chip Identification, chip identification code) of the internal memory of the corresponding device. The other connection response mechanism can be that the first electronic device is connected with the second electronic device in a key mode, when the second electronic device receives the key and is successfully matched, the connection response mechanism can respond to the connection request of the first electronic device, and the connection request of the first electronic device is granted so as to establish connection.
Of course, other connection response mechanisms may be used in addition to the two connection response mechanisms, for example, the first electronic device may send a connection request to the infrared component of the second electronic device through the infrared component, and further, the devices may be mutually identified and connected by using infrared signals. In addition, a screen-throwing connection communication protocol can be defined, the first electronic device sends a connection request carrying the self CID to the second electronic device in the form of RPMB (Replay Protected Memory Block, replay protection memory block) data through the screen-throwing connection communication protocol, and therefore mutual identification and connection of the devices are achieved by means of CID information and RPMB data. Wherein RPMB is a partition with security features inside the memory. Therefore, the safety of screen throwing connection can be improved.
The device display screen identified from the first image may be a display screen of the second electronic device, but may be a display screen of another device, which is not limited herein. It should be noted that, whether the identified device display screen is the display screen of the second electronic device or not, the embodiment of the application can establish screen-throwing connection with the second electronic device through automatic default connection or manual selection connection and other modes, so as to display the display interface of the second electronic device.
In a specific example, as shown in fig. 2, if the mobile phone 21 identifies the menu task bar from the external environment image, it is determined that the current collection object is the display screen of the other device, that is, the mobile phone 21 may be shooting the display screen of the other device, and at this time, a screen-throwing mode may be started to establish a screen-throwing connection with the computer 22, so as to display the display content in the display screen of the computer 22 on the mobile phone 21.
In addition, in another case, that is, in a case where the acquisition object of the first image does not include the device display screen, the normal framing shooting mode is entered.
Based on this, in an alternative embodiment, the step 120 may specifically include:
searching electronic equipment within a preset range;
under the condition that the second electronic equipment is determined to be searched, screen projection connection is established with the second electronic equipment;
receiving screen display information sent by second electronic equipment;
and displaying a display interface of the second electronic device according to the screen display information.
In an exemplary case that the collection object is a device display screen according to the first image, whether a device capable of being connected with a screen is in a preset range around the first electronic device or not may be searched first, if a second electronic device capable of being connected with the screen is identified, a connection request may be automatically sent to the second electronic device, and after a response that the second electronic device agrees to connect is received, connection is established with the second electronic device. If the electronic device is determined not to be searched for any other electronic device or the second electronic device refuses the connection request, the device enters a normal framing shooting mode.
In addition, the screen display information may be video stream information corresponding to the real-time display interface in the display screen of the second electronic device. By receiving the screen display information, a real-time display interface in a display screen of the second electronic device can be displayed on the first electronic device in a screen throwing mode.
Therefore, the screen display information sent by the electronic equipment is received through the other electronic equipment which is automatically connected to perform screen display on the first electronic equipment, so that a clear screen display interface can be conveniently and rapidly obtained, and a user can conveniently obtain the information needed by the user.
In an optional implementation manner, the step of establishing a screen-throwing connection with the second electronic device in the case that the second electronic device is determined to be searched specifically may include:
displaying N pieces of equipment information corresponding to the N pieces of electronic equipment under the condition that the N pieces of electronic equipment are determined to be searched; the N pieces of equipment information comprise second equipment information corresponding to the second electronic equipment;
receiving a first input of second device information by a user;
in response to the first input, a screen-drop connection is established with the second electronic device.
Here, the device information may be information capable of identifying the device identity, such as a device name.
In a specific example, as shown in fig. 3, a screen-throwing mode operation interface 301 corresponding to a photographing APP is displayed in the mobile phone 30, when the mobile phone 30 enters a screen-throwing mode, an operation menu 302 may be displayed, and when a user clicks a screen-throwing connection, the mobile phone 30 may be triggered to be displayed to determine device information 303 corresponding to the searched at least one connectable electronic device. If the user further selects the option 304 in which the device information is "aaa", the electronic device whose device information is "aaa" is connected.
Therefore, through displaying the equipment information corresponding to the searched electronic equipment, the user can conveniently select and connect the electronic equipment which really wants to be connected, the equipment can be effectively prevented from being connected by mistake, and the safety of the screen-throwing connection process is improved.
And 140, acquiring a second image based on the display interface.
In this embodiment of the present application, the manner of acquiring the second image from the display interface of the first electronic device includes, but is not limited to, screen capturing, screen recording, and the like, and accordingly, the number of acquired second images may be one or more. Specifically, the first electronic device may automatically perform screen capturing or screen recording operation based on the display interface, and of course, may perform screen capturing or screen recording operation in any range on the display interface according to the operation of the user, which is not limited herein.
For example, if the user needs to continuously acquire the information in the display interface, the user may select to trigger the screen-projection recording mode to record the information in the current display interface, so as to obtain video clips corresponding to the plurality of second images.
In an alternative embodiment, the step 130 may specifically include:
receiving a second input of a user to the display interface;
and responding to the second input, and performing screen capturing on the display interface to obtain a second image.
Here, the second input may be an input that the user triggers a screen capture, including, but not limited to, tapping the screen with a finger joint, pressing a preset screen capture function combination key on the first electronic device, or clicking a screen capture button displayed in the screen, or the like.
In addition, the screen capture range may be any range in the display interface, such as a specific pattern range, or a user-defined range, etc.
Therefore, through the second input of the user to the display interface, the screen capturing process of the display interface in the first electronic device can be triggered, and further a clear screen capturing image is obtained to serve as a second image.
Therefore, under the condition that the acquisition object is the equipment display screen according to the first image acquired by the camera of the first electronic equipment, the second electronic equipment is connected, the display interface in the second electronic equipment is projected and displayed in the first electronic equipment, and the second image is acquired based on the display interface.
To better describe the overall solution, based on the above embodiments, as a specific example, as shown in fig. 4, the file sharing method may include steps 1001-1012, which are explained in detail below.
here, the user can prepare to photograph an external scene to acquire required information by opening the photographing APP.
here, the camera can capture external scene information, so as to judge whether the computer screen is a computer screen.
here, one mode may be selected from the screen recording mode and the screen photographing mode. For example, if the user needs to continuously acquire screen information of the computer device, the user can select a screen-casting recording mode; if only single screen information of the host end needs to be acquired, a screen shooting mode can be selected.
for example, if the user only needs to acquire the single screen information of the host computer, the user can select the screen shooting mode to perform the screen shooting operation of the screen information of the host computer, and various screen shooting modes such as specific patterns can be supported. Recording screen information at the host side.
for example, if the user needs to continuously acquire the screen information of the computer device, the user can select a screen projection recording mode to record the screen information of the computer device.
Thus, the screen display interface in the computer equipment is displayed on the mobile phone, and the image is acquired based on the display interface, so that better image acquisition effect can be achieved as the image acquisition effect is not influenced by shooting distance, shooting operation, shooting angle and the like. In addition, because the mobile phone camera does not need to be shot against the screen of the computer equipment, the required information can be acquired at any time through the screen-throwing interface, the problem that the operation is complicated because the user also needs to carry out post-processing on the shot image after shooting so as to remove useless information is solved, the operation process is simplified, and the complexity of the user operation is reduced.
