The following takes a terminal device as an example to exemplarily explain the photographing method provided by the embodiment of the present invention.
The photographing method provided by the embodiment of the invention can be applied to a scene of photographing by using small wearable terminal equipment.
Example one
As shown in fig. 1, an embodiment of the present invention provides a photographing method, which may include the following steps:
101. the resolution of the first preview image is adjusted from the first resolution to the second resolution.
Wherein the pixel value of the first resolution is N times the pixel value of the second resolution, and N is an integer greater than or equal to 2.
In the embodiment of the present invention, the first preview image refers to an image displayed in a shooting preview interface on a screen of the terminal device after the camera application is opened and before the image is shot.
In the embodiment of the present invention, the first resolution, the second resolution, the third resolution, and the like all refer to different resolutions.
In the embodiment of the invention, the terminal equipment can support one or more resolutions. For example, 1600W, 800W, 400W, etc., which are not limited in the embodiments of the present invention.
Optionally, the first resolution may be a resolution set by default by a camera application of the terminal device, or may be any one of resolutions supported by the terminal device.
Since the first preview image may be adjusted from the first resolution to the second resolution smaller than the first resolution in the embodiment of the present invention, the first resolution may be a resolution other than the minimum resolution supported by the terminal device.
Illustratively, the default resolution may be 1600W pixels (i.e., the first resolution described above).
For example, assuming that the first preview image is 1600W pixels, after the terminal device opens the camera application in response to the user trigger, the terminal device starts a preset algorithm program, and the algorithm program may synthesize four pixels of the first preview image into one pixel through a pixel synthesis technique, so that a pixel value in the first preview image becomes one fourth of the original value, that is, the first preview image is adjusted to 400W pixels (i.e., the second resolution).
Optionally, before the terminal device adjusts the resolution of the first preview image from the first resolution to the second resolution, the terminal device may be triggered to open the camera application, for example, in a case that it is detected that the user clicks an icon of the camera application, the camera application is opened in response to a clicking operation of the user.
Optionally, after the terminal device receives the click input of the user and before the camera application is opened, whether the user has a false touch condition may be further determined, and the terminal device may determine whether the user has a false touch according to data such as the position, the number, and the area of the touch point of the user touch screen.
Illustratively, the first possible scenario is: if the terminal device detects that the click input of the user on the screen of the terminal device corresponds to a touch point, the touch point is located at the position of the camera application icon, and the area of the touch point is equal to or smaller than the preset touch area, the terminal device considers that the user does not touch by mistake, and the terminal device can open the camera application.
The second possible scenario is: if the terminal device detects that the click input of the user on the screen of the terminal device corresponds to a touch point, the touch point is located at the position of the camera application icon, but the area of the touch point is larger than the area of the preset touch point, the terminal device considers that the user is most likely to be mistaken touch, and the terminal device does not respond to the click input, namely does not start the camera application.
A third possible scenario is: if the terminal device detects that the click input of the user on the screen of the terminal device corresponds to a plurality of touch points, one touch point is located on the camera application icon, and the rest touch points are not located on the camera application, the terminal device considers that the user is most likely to be mistaken touch, and does not respond to the click input, namely does not start the camera application.
Optionally, after the terminal device receives a click input of the user for the camera application program and before the camera application program is opened, the terminal device may obtain facial features of the user, recognize whether the facial features of the user are matched with preset facial features through a built-in face recognition device, open the camera application program if the facial features of the user are matched with the preset facial features, and if the facial features of the user are not matched with the preset facial features, not respond to the click input, that is, not open the camera application program.
Optionally, under the condition that the face recognition device recognizes that the facial features of the user are not matched with the preset facial features, the terminal device may further output prompt information, where the prompt information is used to prompt the user to input the verification information. Wherein, the verification information can be at least one type of verification information of fingerprint, voice, password and security problem.
Through above-mentioned optional implementation, can the discernment of user's facial feature, if user's facial feature does not match with the facial feature that terminal equipment predetermines, will require the user to input authentication information again, can protect terminal equipment like this and can not falsely be used by other people, protected terminal equipment's information safety, avoid revealing of user's privacy information.
102. An instruction to increase the focal length is received.
It can be understood that, at present, the instruction of the terminal device for increasing the focal length is generally realized by sensing the zoom operation of two fingers of the user on the screen, but for some terminal devices with smaller screens, the simultaneous operation of two fingers may be inconvenient. In the embodiment of the invention, the instruction of increasing the focal length can be realized through voice input.
Optionally, the terminal device collects voice information of the user through a microphone, and may analyze the voice information to obtain an instruction for increasing the focal length.
The above-mentioned instruction of obtaining the increase focal length of extracting the speech information includes: first, the terminal device may recognize the content of the voice message, then determine whether the content of the voice message includes preset content (for example, "increase the focal length"), and after determining that the content of the voice message includes the preset content, the terminal device may determine that an instruction to increase the focal length is received, and the terminal device may respond to the instruction.
Further, after the voice message is determined to include the preset content, a voiceprint feature corresponding to the voice message can be determined, then the voiceprint feature is compared with the preset voiceprint feature, if the voiceprint feature is matched with the preset voiceprint feature, the terminal device can determine that an instruction for increasing the focal length is received, the instruction is an instruction sent by a preset user, and the terminal device can respond to the instruction; if the voiceprint feature does not match the preset voiceprint feature, the terminal device may determine that the instruction for increasing the focal length is received, but the instruction is not an instruction sent by a preset user, and the terminal device may not respond to the instruction.
In the implementation mode, the corresponding operation instruction is obtained by collecting the voice information of the user, so that the operation steps of the user can be greatly reduced, the complex operation which can be realized originally only by hands can be realized only through voice, and the man-machine interaction capability is improved. Furthermore, through the comparison of the voiceprint characteristics and the preset voiceprint characteristics, the voice information can be determined to be sent by the preset user, and the phenomenon that the terminal equipment is falsely used by other people to cause the leakage of the privacy information is avoided.
103. In response to the instruction to increase the focal length, the resolution of the first preview image is adjusted from the second resolution to the third resolution.
Wherein the pixel value of the third resolution is M times the pixel value of the second resolution, and M is an integer greater than or equal to 2.
Optionally, the third resolution may be a resolution set by default by a camera application of the terminal device, or may be any one of resolutions supported by the terminal device.
Since the first preview image may be adjusted from the second resolution to the third resolution with a higher resolution in the embodiment of the present invention, the third resolution may be a resolution other than the minimum resolution supported by the terminal device.
For example, assuming that the first resolution is 1600W pixels, the second resolution may be 400W pixels or 800W pixels; assuming that the second resolution is 400W pixels, the corresponding third resolution may be 800W pixels or 1600W pixels; assuming that the second resolution is 800W pixels, the corresponding third resolution may be 1600W pixels.
Optionally, in this embodiment of the application, the terminal device may set different corresponding resolution parameters for different focal length magnification factors, and store the different resolution parameters in the terminal device.
After the terminal device confirms the first focal length magnification, the resolution parameter corresponding to the first focal length magnification can be obtained from the saved resolution parameters.
Illustratively, the terminal device may store different resolution parameters corresponding to different focal length amplification factors in a corresponding relationship, so that when a resolution parameter under a certain focal length amplification factor needs to be obtained, the resolution parameter under the focal length amplification factor may be directly determined through the stored corresponding relationship.
Exemplarily, as shown in table 1, the relationship between different focal length magnifications and different resolution parameters is shown.
TABLE 1
| Focal length magnification factor | Resolution parameter |
| First focal length magnification | First resolution parameter |
| Second focal length magnification | Second resolution parameter |
| Third focal length magnification | Third resolution parameter |
| Fourth focal length magnification | Fourth resolution parameter |
| Fifth focal length magnification | A fifth resolution parameter |
In combination with table 1, when the first focal length magnification is determined, the resolution parameter at the first focal length magnification may be determined as the first resolution parameter by querying in table 1.

| Portrait of human | Portrait mode |
| Landscape | Landscape mode |
| Food | Food mode |
| Pet animal | Pet mode |
| Night scene | Night scene mode |

And after receiving the operation of determining that the target image is sent to the friend, detecting whether the communication account information of the friend exists in the address list.
Illustratively, the user has a friend nail, and the facial feature information of the friend nail is prestored in the terminal equipment. After the target image is obtained, the terminal equipment identifies the target image, and if the facial feature information of the friend nail is identified, prompt information is output to a user to prompt whether the target image is sent to the friend nail or not. After the user clicks the confirmation sending, the terminal equipment receives an instruction for determining that the target image is sent to the friend nail, and then starts to detect whether the communication account information of the friend nail exists in the address list.
311. And sending the target image to the friend through the communication account information.
And if the communication account information of the friend exists, the target image is sent to the friend through the communication account information.
312. Backing up the target image to another associated device associated with the terminal device
For example, assuming that the contact of the wechat application on the terminal device has the account of the friend nail, the terminal device may automatically send the target image to the friend nail through wechat. And if the communication account information of the friend does not exist, backing up the target image to the associated equipment. For example, assuming that all social applications and the address book on the terminal device do not have the account number of the friend nail, the terminal device will automatically backup the target image to another associated device associated with the terminal device.
In the implementation mode, the terminal device determines whether the image has the associated friend or not by acquiring the facial feature information of the friend in the image, detects whether the address list has the communication account information or not, and sends the communication account information to the friend. Therefore, the operation of searching the friend communication account information by the user can be greatly reduced, the time is saved, and the man-machine interaction performance of the terminal equipment is improved.
