Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The execution main body of the display information extraction method provided by the embodiment of the present invention may be a terminal device, or may also be a functional module and/or a functional entity capable of implementing the display information extraction method in the terminal device, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited.
The terminal device provided in the embodiment of the present invention may be a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, an electronic photo frame, a Personal Digital Assistant (PDA), an intelligent watch, an intelligent bracelet, or the like, or the terminal device may be other types of terminal devices, which is not limited in the embodiment of the present invention.
An embodiment of the present invention provides a display information extraction method, which is shown in fig. 1 and includes:
s101, under the condition that the first preset operation is detected, extracting display information corresponding to the first time.
The first moment is the moment when the first preset operation is detected.
Specifically, the first preset operation in the embodiment of the present invention may specifically be a touch click operation of a screen of the terminal device by a user, or a click operation of a control of the terminal device by a peripheral device such as a mouse by the user, or a voice instruction input by the user, or a specific gesture input by the user.
In some embodiments of the present invention, the specific gesture may be any one of a single-tap gesture, a slide gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-tap gesture.
Optionally, the display information corresponding to the first time is an image displayed on a screen of the terminal device at the first time.
Namely, the first preset operation is used for triggering screen capture, and the captured image is an image displayed on a screen of the terminal device at the first moment. For example: the terminal equipment plays a cartoon, when a user wants to intercept a certain image, a first preset operation is input to the terminal equipment, and the terminal equipment detects the first preset operation and immediately extracts the image displayed on a current screen.
Optionally, the display information corresponding to the first time is an image stream displayed on a screen of the terminal device at the first time and after the first time.
Namely, the first preset operation is used for triggering screen recording, and the recorded video is an image stream displayed on a screen of the terminal equipment at the first moment and after the first moment. For example, when a user wants to record a screen from a current time while a terminal device is playing a teaching video, a first preset operation is input to the terminal device, and the terminal device detects the first preset operation and immediately extracts an image stream displayed on the screen at the current time and after the current time.
Further, the implementation manner of detecting the first preset operation may be: and under the condition that the screen of the terminal equipment is lightened, starting a corresponding sensor based on the type of the first preset operation, and detecting the first preset operation in real time. For example: the first preset operation is voice input, and then the microphone is started to detect the first preset operation in real time, for example: and if the first preset operation is a touch operation, starting the touch panel to detect the first preset operation in real time.
It should be noted that the extracted display information corresponding to the first time may be stored in a temporary storage space, such as a cache, a memory, and the like, which is not limited in this embodiment of the present invention.
Because the extracted display information is the display information corresponding to the moment when the terminal device detects the first preset operation of the user, no matter a static picture is captured or a video picture which is played in a rolling mode is captured or recorded, the embodiment of the invention can capture the required picture information by setting the first preset operation which can be input quickly, so that the user can capture the picture information which is required by the user through inputting the first preset operation quickly, and the situation that the display information which is required to be extracted is missed due to the fact that the video picture information rolls constantly is avoided.
S102, judging whether a second preset operation is received within a preset time.
Specifically, the second preset operation in the embodiment of the present invention may be the same operation as the first preset operation, or may be another operation different from the first preset operation, and if the terminal device receives the second preset operation within the preset time, the following step S103 is executed; if the second predetermined operation is not received within the predetermined time, the following step S104 is executed.
In order to input the first preset operation quickly, the first preset operation needs to be set simply, and therefore, the user may trigger the first preset operation by mistake in the process of using the terminal device. The embodiment of the invention has the effect of confirming the screen capturing or recording operation sent by the user by detecting whether the second preset operation is received within the preset time, and can effectively avoid the terminal equipment from carrying out unnecessary screen capturing or recording due to misoperation of the user.
S103, storing the display information corresponding to the first moment to a preset database.
Specifically, when the display information corresponding to the first moment is an image displayed on the screen of the terminal device at the first moment, if the terminal device detects a second preset operation of screen capture within a preset time, the image captured at the first moment is stored in a preset database, and when the display information corresponding to the first moment is the first moment and an image stream displayed on the screen of the terminal device after the first moment, if the terminal device detects the second preset operation of screen capture within the preset time, the screen capture result starting from the first moment is stored in the preset database, and the video information of the terminal device is continuously captured, and an instruction of receiving and capturing the screen is waited.
And S104, deleting the display information corresponding to the first moment.
It should be noted that, in the embodiment of the present invention, deleting the display information corresponding to the first time refers to deleting the display information corresponding to the first time from a temporary storage space for storing the display information corresponding to the first time. In the using process of the terminal equipment, a user inputs a first preset operation by mistake, the terminal equipment extracts the display information corresponding to the first moment, but because the first preset operation is the misoperation, the user can not input a second preset operation to the terminal equipment, and the terminal equipment can not receive the second preset operation within the preset time, the terminal equipment can confirm that the detected first preset operation is the misoperation of the user, and then the extracted display information corresponding to the first moment is deleted, so that the occupation of unnecessary images or video information and the waste of the storage space of the terminal equipment are effectively avoided.
In addition, the display information corresponding to the first moment is extracted and deleted, so that the user can be unaware of the deletion of the display information corresponding to the first moment, and the use experience of the user is improved.
The display information extraction method provided by the embodiment of the invention extracts the display information corresponding to the moment when the first preset operation is detected under the condition that the first preset operation is detected, and judges whether a second preset operation is received within a preset time, if the second preset operation is received within the preset time, the display information corresponding to the first moment is stored in a preset database, and if the second preset operation is not received within the preset time, the display information corresponding to the first moment is deleted. On the first hand, when a user wants to extract the display information of the screen, the display information of the screen can be immediately extracted by inputting a first preset operation, so that even if the display information of the screen is a video picture which rolls from time to time, the user can quickly start a screen capture or recording function to extract the display information of the screen, and the situation that the user misses the opportunity and cannot extract the required picture or video clip is avoided; in a second aspect, after the first preset operation is detected and the display information of the screen is extracted, the second preset operation needs to be detected to store the extracted display information into the preset database, otherwise, the extracted display information is deleted, so that the embodiment of the invention can also avoid the storage space occupied by extracting the unnecessary images or videos. In summary, the embodiments of the present invention can avoid wasting the storage space while enabling to quickly start screen capturing or recording.
As an optional implementation manner of the embodiment of the present invention, detecting whether a second preset operation is received within a preset time specifically includes:
starting a timer when a first preset operation is detected, and detecting a second preset operation before the timer finishes timing; if a second preset operation is detected before the timer finishes timing, determining that the second preset operation is received within a preset time, and storing display information corresponding to the first time into a preset database; and if the second preset operation is not detected after the timer finishes timing, determining that the second preset operation is not received within the preset time, and deleting the display information corresponding to the first moment.
Illustratively, the preset time may be 0.5 second, within 0.5 second after the terminal device detects the first preset operation, if the terminal device detects the second preset operation at any time, timing is stopped, and the display information corresponding to the first time is stored in the preset database; and if the terminal equipment does not detect any operation or only detects other operations except the second preset operation, deleting the display information corresponding to the first moment.
In one embodiment, the first preset operation is an operation of knocking the screen by a finger joint; the second preset operation is an operation of knocking the screen by the finger joint.
On one hand, the operation of knocking the screen by the finger joint is easy to input, and the user does not need to spend much time, so that the first preset operation can be quickly input when the user wants to extract the display information of the screen, and the picture or the video clip which is wanted to be extracted is avoided missing. On the other hand, the operation of knocking the screen by the finger joint is less used in the process of operating the terminal device, so that the first preset operation and the second preset operation are set as the operation of knocking the screen by the finger joint, the conflict with other operations can be avoided, and the misoperation is reduced.
Referring to fig. 2, when the first preset operation is an operation of tapping the screen by a finger joint and the second preset operation is an operation of tapping the screen by a finger joint, the method for extracting display information according to the embodiment of the present invention includes:
s201, detecting whether the acceleration of the terminal equipment is larger than a threshold acceleration.
Specifically, the acceleration of the terminal device can be obtained in real time through an acceleration sensor of the terminal device, and whether the acceleration of the terminal device is greater than a threshold acceleration is judged.
When the terminal equipment receives the operation of knocking the screen by the knuckle, the terminal equipment generates certain acceleration under the knocking action, so that whether the terminal equipment possibly receives the operation of knocking the screen by the knuckle can be judged by judging whether the acceleration of the terminal equipment is greater than the threshold acceleration.
In step S201, if the acceleration of the terminal device is greater than the threshold acceleration, the following step S202 is executed.
S202, judging whether a touch event exists or not.
Specifically, a touch panel of the terminal device may be started, and whether a touch event exists is detected in real time through the touch panel.
The terminal device can generate a touch event when receiving the operation of knocking the screen by the knuckle, so that when the acceleration of the terminal device is detected to be larger than the threshold acceleration, whether the touch event exists or not can be further judged, whether the operation of knocking the screen by the knuckle is possibly received by the terminal device or not is judged, if the touch event is detected, the operation of knocking the screen by the knuckle is determined to be possibly received, and if the touch event is not detected, the operation of knocking the screen by the knuckle is determined not to be received.
In step S202, if a touch event is detected, the following step S203 is performed.
S203, judging whether the touch area of the touch event is smaller than the threshold area.
Compared with the touch area of the touch event generated by the finger tip and the like, the touch area of the touch event generated by the finger joint is smaller, so that whether the touch event is generated by the operation of knocking the screen by the finger joint can be further judged based on whether the touch area is smaller than the threshold area, and whether the received operation is the operation of knocking the screen by the finger joint is further determined.
In step S203 described above, if the touch area of the touch event is smaller than the threshold area, it may be determined that the terminal device has received an operation of tapping the screen with a finger joint (first preset operation), and the following step S204 is performed.
And S204, extracting the display information corresponding to the first moment.
After the display information corresponding to the first time is extracted, the display information extraction method according to the embodiment of the present invention further needs to perform the following steps S205 to S207 to determine whether the first preset operation is a misoperation.
S205, detecting whether the acceleration of the terminal equipment is larger than the threshold acceleration within the preset time.
Also, whether the acceleration of the terminal device is greater than the threshold acceleration may be detected by an acceleration sensor of the terminal device.
If the acceleration of the terminal device is always less than or equal to the threshold acceleration within the preset time, it may be determined that the operation of tapping the screen by the knuckle for the second time (the second preset operation) is not received within the preset time after the first preset operation is detected, and thus the following step S206 is performed.
S206, deleting the display information corresponding to the first moment.
If the acceleration of the terminal device at a certain time within the preset time is greater than the threshold acceleration, it may be determined that an operation of tapping the screen by the knuckle for the second time (a second preset operation) may be received within the preset time after the first preset operation is detected, and thus the following step S207 is performed to further determine whether an operation of tapping the screen by the knuckle for the second time is received within the preset time.
And S207, judging whether a touch event exists in the preset time.
In the above step S207, if there is no touch event within the preset time, it may be determined that the operation of tapping the screen by the knuckle for the second time (the second preset operation) is not received within the preset time after the first preset operation is detected, and thus the above step S206 is performed, whereas if there is a touch event within the preset time, it may be determined that the operation of tapping the screen by the knuckle for the second time (the second preset operation) is likely to be received within the preset time after the first preset operation is detected, and thus the following step S208 is performed to further determine whether the operation of tapping the screen by the knuckle for the second time is received within the preset time.
And S208, judging whether the touch area of the touch event is smaller than a threshold area.
In step S208, if the touch area of the touch event is greater than or equal to the threshold area, it may be determined that the current operation is not an operation of tapping the screen with a finger joint, and may be an operation generated by a finger tip or the like, and thus step S206 is performed. On the other hand, if the touch area of the touch event is smaller than the threshold area, it may be determined that an operation of tapping the screen by the knuckle for the second time (a second preset operation) is received within a preset time after the first preset operation is detected, and thus the following step S209 is performed.
S209, storing the display information corresponding to the first moment to a preset database.
In another embodiment, the first preset operation is an operation of knocking the screen by a finger joint; the second preset operation is an operation of double-clicking the screen by the finger joint.
Compared with the operation of knocking the screen by the finger joint in the second preset operation, when the second preset operation is the operation of double-clicking the screen by the finger joint, the operation of knocking the screen by the finger joint is received twice in the preset time, and the display information corresponding to the first moment is stored in the preset database, otherwise, the display information corresponding to the first moment is deleted. That is, in the embodiment shown in fig. 2, after the execution of the above S204, the above steps S205 to S208 need to be executed twice in succession, and the above step S209 is executed only if the operations of tapping the screen by the knuckle are received twice in succession within a preset time, otherwise, the above step S206 is executed.
Setting the second preset operation as an operation of double-clicking the screen with the finger joint can further reduce the erroneous operation, compared with an operation of tapping the screen with the finger joint as the second preset operation.
As an optional implementation manner of the embodiment of the present invention, the display information extraction method provided by the present invention includes:
and outputting the indication information.
The indication information is used for indicating that the display information corresponding to the first moment is extracted.
For example, referring to fig. 3, in fig. 3, a thumbnail of the captured image is displayed on the screen of the terminal device in a manner that the display information corresponding to the first time is the image displayed on the screen of the terminal device at the first time and the indication information is output. As shown in fig. 3, when a second preset operation is received within a preset time, a thumbnail 31 of the captured image is displayed on the screen of the terminal device to prompt the user that the display information corresponding to the first time has been extracted.
As an optional implementation manner of the embodiment of the present invention, the display information corresponding to the first time is an image stream displayed on the screen at the first time and after the first time, and the method provided by the embodiment of the present invention further includes:
and receiving a third preset operation input by the user.
And responding to a third preset operation, stopping extracting the display information corresponding to the first moment, namely stopping recording the screen.
Specifically, the third preset operation in the embodiment of the present invention may be a touch and click operation of a virtual control used for triggering to stop recording of a screen by a user, or a click operation of a virtual control used for triggering to stop recording of a screen by a user through a peripheral device such as a mouse, or a voice instruction input by the user, or a specific gesture input by the user.
That is, when the embodiment of the present invention is used for recording a screen, the user may also stop extracting the display information corresponding to the first time through the third operation control terminal device, so as to obtain an image stream from the first time to a time when the third preset operation is input.
Based on the same inventive concept, as an implementation of the foregoing method, an embodiment of the present invention further provides a terminal device that executes the method for extracting display information provided in the foregoing embodiment, where the embodiment of the terminal device corresponds to the foregoing method embodiment, and for convenience of reading, details in the foregoing method embodiment are not repeated one by one in the embodiment of the present device, but it should be clear that the terminal device in the present embodiment can correspondingly implement all the contents in the foregoing method embodiment.
Fig. 4 is a schematic structural diagram of a terminal device according to an embodiment of the present invention, and as shown in fig. 4, the terminal device 400 according to this embodiment includes:
