Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, most mobile electronic devices are provided with a front camera and a rear camera, which is convenient for users to use the electronic devices to take self-timer, but the pixels of the front camera in the current electronic devices are generally low, the quality of the taken images cannot meet the requirements of the users, and the users still take images by using the rear camera of the electronic devices under normal conditions.
However, in the process of self-shooting by using a rear camera of an electronic device, a user cannot see a display screen of the electronic device, and cannot see a preview image presented by the display screen, so that whether a shot object in the preview image meets the shooting requirement of the user cannot be known, the user can only shoot the image by feeling, the stored preview image often has the problems of blurring of the shot object, incompleteness of a shot object contained in the preview image, imperfect background selection and the like, and thus, the user is required to shoot the same shot object for multiple times, which is troublesome, especially under the condition that the shot object contains multiple shot objects, the shooting efficiency is greatly reduced, and even the preview image meeting the shooting requirement of the user cannot be obtained.
In order to improve the problem, the method and the device provide corresponding prompt information aiming at the specific situation of the shot object in the current preview image, so that a user can judge whether the image information of the shot object contained in the current preview image meets the shooting requirement of the user according to different heard prompt information, the preview image presented by the display screen does not need to be checked, the image meeting the user requirement can be quickly obtained through self shooting, and the method and the device are very convenient and practical.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flowchart of an image capturing control method provided in an embodiment of the present application may include:
step S11, detecting that the electronic equipment enters a first shooting mode, and acquiring a preview image in the first shooting mode;
the first shooting mode can be that the electronic equipment starts a rear camera to shoot, namely the rear camera shooting mode, and in the first shooting mode, a user can not conveniently watch a preview image displayed on a display screen of the electronic equipment in real time.
It should be noted that, of course, for the reason that the shooting user cannot watch the presented preview image in real time through eyes to determine whether the preview image meets the shooting requirement of the shooting user due to the physical problem of the shooting user or other factors, the first shooting mode may also refer to a front-facing camera shooting mode of the electronic device, and the specific reference content of the first shooting mode of the electronic device is not limited in the present application.
In practical application, after the electronic device enters a shooting mode, a camera device included in the electronic device collects images of a shot object in a current shooting range to obtain a corresponding preview image, and at this time, if the electronic device has a display screen, the preview image is usually presented on the display screen. It should be noted that the obtained preview image cannot be saved only, and it may change with the change of the shooting range of the electronic device.
Step S12, detecting the preview image, and obtaining image information of the subject in the preview image;
in this embodiment, the image processing and analyzing technology may be utilized to pre-process and analyze the acquired preview image, and determine the image information of the subject included in the preview image, such as whether a preset type of subject appears, the number, posture, and the like of the subject.
Optionally, in practical applications, requirements of a shooting user for shooting an image may be predefined, for example, how many shot objects need to be included, or a target shooting object needs to be included, and the like, and a position of the shooting object in the preview image may also be set, and the detailed description of the application is omitted here.
The present application may combine the face detection and recognition technology to detect the photographic subject of the photographic subject in the preview image, and may further count information such as the number of the photographic subjects included in the photographic subject, but is not limited to this photographic subject detection method.
Step S13, outputting corresponding prompt information based on the image information;
based on the above description, it is known that the image information of the subject in the obtained preview image can represent the actual situation of the subject in the preview image, and the output prompt information corresponding to the image information can accurately represent the specific shooting situation of the subject in the current preview image.
Optionally, before the electronic device is used for image shooting, the user may set different prompt messages sent by the electronic device under different shooting conditions according to the preference of the user.
For example, the number of persons included in the subject is set, as shown in the configuration interface shown in fig. 2, when the user selects the rear camera self-timer mode, the system can output a setting option for prompting "number of persons", at this time, the user can input the number of persons participating in self-timer shooting, and then, after the number of the included subjects is determined by analyzing the image information of the subject, it can be verified whether the number is the same as the preset number of persons, and different prompting information is output according to the verification result.
Different prompt tones can be set for different numbers of shot objects, so that a shooting user can determine that the current preview image contains several shot objects according to the received prompt tones, and correspondingly adjust the shooting angle of the electronic equipment according to the received prompt tones, thereby quickly obtaining the shot image meeting the requirements. Of course, the application can also output corresponding prompt information directly according to the verification result. The output rule of the prompt message is not limited, and the shooting user can set the prompt message according to own habits. Is very flexible and convenient.
Therefore, the method and the device can determine the number of the shooting objects contained in the shot object by analyzing the image information of the shot object, and output the prompt information corresponding to the determined number of the shooting objects, so that a shooting user can accurately know whether the currently acquired preview image is the image required by the user according to the prompt information, and the method and the device are very convenient.
Optionally, the prompt information may be various types of prompt tones, or may be voice information including voice content, and the output mode of the prompt information is not limited in the present application.
And step S14, when the prompt message indicates that the image information meets the preset shooting requirement, generating a shooting instruction, and controlling the electronic equipment to store the preview image.
In practical application, after receiving the prompt information currently output by the electronic device, the shooting user may determine whether to store the currently obtained preview image according to the prompt mode or the prompt content of the prompt information, and if the shooting user determines that the currently obtained preview image meets the shooting requirement according to the output content or the mode of the prompt information, that is, the image information of the object to be shot in the preview image meets the preset shooting requirement, the shooting button of the electronic device may be pressed to generate a corresponding shooting instruction, so as to control the electronic device to store the currently obtained preview image.
The specific verification means adopted by the electronic equipment is not limited, and the number of the shot objects contained in the shot object can be determined by combining the human face detection technology as described above, and then the shot objects are compared with the preset shot number to trigger a prompt circuit corresponding to the comparison result to output corresponding prompt information; alternatively, after the target photographic object is identified, the position of the target photographic object in the preview image may be analyzed, whether the position meets the preset position requirement is judged, and corresponding prompt information is output according to the judgment result, and the like.
In addition, the present application does not limit the generation method of the shooting command, and the shooting command may be generated by triggering a shooting button, or by detecting a voice signal.
In summary, in this embodiment, after the electronic device acquires the preview image in the first shooting mode, the image information of the object to be shot in the preview image can be obtained by detecting the preview image, so that the corresponding prompt information is output based on the image information to inform the shooting user whether the preview image is the shooting image required by the shooting user, which meets the shooting requirement of the shooting user who is inconvenient to view the preview image displayed on the display screen of the electronic device during the shooting process, so that the shooting user can shoot the image meeting the requirement more quickly, and the shooting efficiency is improved.
Referring to fig. 3, a flowchart of another image capturing control method provided in this embodiment is provided, where this embodiment mainly explains an application scenario in which a plurality of capturing objects capture images as an example, and the method specifically may include the following steps:
step S31, receiving configuration parameters input by the user aiming at the shooting requirement;
the configuration parameters include the number of the shooting objects and/or status information, and may be specifically determined according to the shooting requirement.
It should be noted that, the input mode of the configuration parameters is not limited in the present application, and the corresponding configuration parameters may be input by entering the corresponding configuration interface, as shown in fig. 2, but is not limited to the interface shown in fig. 2. In addition, the state information of the photographic subject may include the motion, posture, and position of the photographic subject in the preview image, and the like.
Optionally, in practical application, when the electronic device enters the first shooting mode, the electronic device may directly output a corresponding configuration interface, so that a shooting user sets configuration parameters of the first shooting mode, and of course, this manner may also be adopted for other shooting modes of the electronic device.
In addition, the electronic device may also output a configuration interface of the shooting mode after detecting the configuration instruction of the shooting mode, and at this time, the shooting user may input corresponding configuration parameters for various shooting modes of the electronic device.
Step S32, configuring the first shooting mode of the electronic equipment by using the configuration parameters;
in practical application, after detecting that the shooting user completes the configuration completion instruction of the first shooting mode, the configuration of the first shooting mode can be directly realized by using the currently output configuration parameters, so that after the electronic device enters the first shooting mode, the analysis and judgment of the image information of the shot object in the preview image are realized according to the corresponding configuration parameters, and the analysis and judgment can be specifically determined according to the contents of the configuration parameters, which is not described in detail herein.
Step S33, controlling the electronic equipment to acquire a preview image in a first shooting mode;
step S34, detecting the preview image, and obtaining image information of the subject in the preview image;
a step S35 of analyzing the image information and determining the number of subjects included in the subject;
in the present embodiment, the number of the photographic subjects included in the subject may be determined by combining the face detection and recognition technology, but is not limited to this determination.
It should be noted that, when counting the number of objects included in a subject in a preview image by using a face detection technology, a complete face is usually shot and then taken as a shot object, and if only half of a face of a certain shot object is shot in the preview image, the electronic device will not detect the shot object, and will not count the number of the shot objects included in the current subject.
Step S36, verifying whether the determined number of the photographic subjects is the same as the preset number of the photographic subjects in the configuration parameters, if not, proceeding to step S37, if yes, executing step S39;
step S37 of outputting presentation information indicating the number of subjects included in the subject in the preview image;
in practical applications, when the electronic device determines that the number of the shooting objects included in the shot object in the acquired preview image is incomplete, that is, the number of the shooting objects does not reach the preset setting, prompt information indicating the incomplete shooting objects is output, so that the user can know the incomplete shooting objects, and the shooting angle or the shooting position of the electronic device can be adjusted to acquire a new preview image.
Alternatively, if it is detected that the subject includes one photographic subject, a prompt sound such as a drop … …, a drop … …, a drop … … "may be output, or a vibration prompt of" hum … …, hum … …, hum … … "may be output; or the indicator light is controlled to flash according to a first rule, such as the LED light flashes at once.
If it is detected that the subject includes two subjects, another warning sound different from the warning sound of the one subject may be given, and the warning information output at this time may be a warning sound of "a droplet … …, … …, … …", a vibration warning of "a hum … …, a hum … …, a hum … …", a blinking of two LED lights, or the like.
If the number of the shooting objects is preset to be 3, when the fact that the shot object comprises three shooting objects is detected, a prompt sound of 'dripping' prompt, a continuous 'buzzing' vibration sound, a normally-on LED lamp and the like can be output. But is not limited thereto.
Therefore, when different numbers of shot objects are detected, the electronic device can give different prompt messages, so that a shooting user can know that several people enter a shooting range in a self-shooting process according to the prompt messages, the method is not limited to the listed prompt modes, as long as the number of shot objects can be distinguished, and the embodiment is not detailed one by one.
Step S38, adjusting the shooting angle and/or the shooting depth of field of the electronic equipment by using the obtained adjusting instruction, and returning to the step S33;
in practical applications, if the number of the objects included in the subject in the current preview image is not enough, a new preview image can be obtained by adjusting the shooting distance of the electronic device, for example, by using a long-range shooting method, but the present application is not limited thereto, and the purpose of including the required objects in the preview image is to obtain the new preview image.
Based on this, after the shooting angle and/or the shooting depth of the electronic device is adjusted, the preview image obtained by the electronic device will be changed, and at this time, the step S33 may be returned to obtain the preview image again, and the new preview image is verified in the above manner until the number of the shooting objects is the same as the number of the preset shooting objects in the configuration parameters.
And step S39, outputting countdown prompting information, generating a shooting instruction when the counting is finished, and controlling the electronic equipment to store the preview image.
Since the preview image acquired by the electronic device is a real-time image of the subject, after determining that the preview image acquired by the electronic device is the required shot image, the electronic device can output countdown prompt information for prompting the user to perform image shooting, so as to prompt the user to perform image shooting, and can perform preparations before shooting, such as expression adjustment, and the like, so as to obtain the satisfactory shot image.
Optionally, when the verification result in step S36 is yes, other manners may also be used to output a prompt message to inform the shooting user of the verification result, and the method is not limited to the countdown manner described in this embodiment.
In summary, referring to fig. 4(a) and 4(b), in the present application, in a multi-user self-photographing scene, according to the control method, the prompt information corresponding to the number of the photographing objects included in the subject in the current preview image can be provided, so that a situation that half of a face or an insufficient number of people appears in the obtained photographed image is avoided, repeated photographing is not needed, and the image photographing efficiency is improved.
Referring to fig. 5, for a flowchart of another image capturing control method provided in the embodiment of the present application, the method mainly explains the steps different from the above-mentioned embodiment, and regarding the description of the implementation process of step S51 to step S54, reference may be made to the description of the steps corresponding to step S31 to step S34, and the present embodiment is not described in detail here, then the method may further include:

Optionally, in the present application, by analyzing the image information, state information of each photographic subject included in the photographic subject may be obtained, and by using a face recognition technique, each photographic subject is recognized, so as to determine whether the photographic subject includes the target photographic subject.
Specifically, a face image of the target object may be captured and stored in advance, and when image information of the object in the preview image is analyzed, each detected face image may be compared with the stored face image, so that whether the object includes the target object is determined according to the comparison result.
It should be noted that the method for determining whether the target photographic subject is in the above-described face recognition mode is not limited, and the target photographic subject may be recognized in a voice recognition mode, and the specific implementation process is similar, and the detailed description is not repeated here.
Step S56, verifying whether the state information of the target shooting object meets the preset shooting requirement, if not, entering step S57; if yes, go to step S59;
wherein the preset shooting requirement may be determined for the content of the state information, and if the state information is the display position of the target shooting object, the preset shooting requirement may include a target position of the target shooting object in the preview image; if the status information includes a motion of the target photographic subject, the preset photographic requirement may include a target motion of the target photographic subject, and the like.
The present application is not limited to the detection method of the motion posture of the target photographic subject.
