It should be noted that the mobile terminal described above does not limit the application scenario of the shooting control method provided in the embodiment of the present application.
For convenience of description, the embodiments of the present application will be described in detail by taking an example in which a photographer photographs a photographic subject using a rear camera of a mobile terminal. Referring to fig. 4, fig. 4 is a schematic flowchart illustrating steps of a photographing control method according to an embodiment of the present application, where the method includes the following steps:
s201, acquiring characteristic information of a photographer and shooting information of a plurality of shooting objects to determine a target shooting object from the plurality of shooting objects according to the characteristic information of the photographer and the shooting information of the plurality of shooting objects.
After a photographer opens a shooting application installed on the mobile terminal, the display unit of the mobile terminal displays the framing content of the shooting application, and after the photographer controls the shooting application to start shooting, the mobile terminal enters a shooting state. After the mobile terminal enters a shooting state, a shooting object in a view finding range is selected as a main shooting object, and shooting is carried out on the main shooting object. In a specific implementation process, the mobile terminal selects the main shooting object either actively or by being specified by a photographer.
In the process that the mobile terminal shoots the main shooting object, the front camera and the rear camera can acquire information in real time and send the information to the processor for processing. The front camera collects the image information of the photographer and sends the collected image information to the processor, and the processor processes and identifies the image information of the photographer so as to obtain the characteristic information of the photographer. The rear camera collects shooting information of each shooting object in the view finding range and sends the collected shooting information of each shooting object to the processor.
Wherein the characteristic information of the photographer includes at least one of face orientation information of the photographer and focus information of a line of sight on a display unit of the mobile terminal.
The image information of the photographer comprises a face image of the photographer, and the processor processes and recognizes the image information of the photographer to obtain characteristic information of the photographer, for example, the image recognition of the face image of the photographer is performed, the pupil contour and the eye corner diagonal line of two eyes in the face image are recognized, and the focus position of the sight line on the screen is calculated according to the displacement between the pupil center and the eye corner diagonal line center of a single eye and the displacement between the midpoint of the pupil center connecting line of the two eyes and the center of the eye image.
For example, the eyeball tracking technology can be adopted to obtain the focusing position of the sight line on the screen, the sensor arranged on the mobile terminal is used for emitting infrared rays, the front camera captures the video of the human eye, the processor processes the video of the human eye, so that the positions of the pupil and the corneal reflection point are obtained, and finally the sight line angle is determined according to the deviation of the pupil and the corneal reflection point.
For example, the face orientation information of the photographer may be obtained by training a neural network model and inputting a face image of the photographer to the neural network model.
After the characteristic information of the photographer and the shooting information of the shooting object are acquired, the processor can determine the target shooting object from the plurality of shooting objects according to the characteristic information of the photographer and the shooting information of the shooting object.
In some embodiments, determining a target photographic subject from a plurality of photographic subjects includes: determining whether an interfering object exists in the plurality of photographic objects according to the photographic information of each photographic object; if an interfering object exists in the plurality of objects, a target object is determined according to the characteristic information of the photographer and the imaging information of the interfering object.
The interference object is an object which can cause sound or image interference to the current main shooting object in the shooting process. The mobile terminal can determine whether an interference object exists in the plurality of shot objects according to the acquired shooting information of each shot object, so that shooting parameters can be adjusted in time, and the shooting effect is optimized.
The shooting information comprises at least one of image information of a shooting object shot by the rear camera and sound information of the shooting object collected by the microphone group. When determining the interfering object, it may be determined whether the photographic object is the interfering object by setting a preset threshold.
In some embodiments, determining whether an interfering object exists in a plurality of photographic subjects according to the photographic information of each photographic subject includes: determining whether the image proportion of each shot object exceeds a first preset threshold value or not according to the image information; if the image proportion of the shot object exceeds a first preset threshold value, determining the shot object as an interference object; or determining whether the volume of each shot object exceeds a second preset threshold according to the sound information; and if the volume of the shot object exceeds a second preset threshold, determining that the shot object is an interference object.
The image ratio refers to a ratio of an image of a shooting object to a view range of the mobile terminal, the first preset threshold may be an image ratio threshold, for example, the processor processes and calculates image information of the shooting object to obtain a view ratio of each shooting object, that is, a ratio of the image of the shooting object to the view range of the mobile terminal, and determines whether the view ratio of the shooting object exceeds the first preset threshold, if the view ratio of the shooting object exceeds the first preset threshold, the shooting object is considered as an interfering object, and interference may be generated on a current shooting effect.
The second preset threshold may be, for example, a volume threshold, the processor determines, according to the sound information of the photographic subject, a volume when the photographic subject makes a sound, and determines whether the volume of the photographic subject exceeds the second preset threshold, and if the volume of the photographic subject exceeds the second preset threshold, the photographic subject is considered as an interfering subject, which may interfere with the current photographic effect.
In some embodiments, if it is determined that there is no interfering object in the photographic objects, the main photographic object currently being photographed is continuously photographed to ensure a photographing effect on the main photographic object.
In some embodiments, before determining whether an interfering object exists in the objects when the photographer takes a picture of a person, face recognition may be performed on each object to determine whether each object appearing in the view range of the mobile terminal is a person, and if a subject appearing in the view range of the mobile terminal is not a person, the determination of the interfering object may not be performed on the object.
For example, two shooting objects, namely a boy and a big tree, appear in the view finding range of the mobile terminal, firstly, face recognition is respectively carried out on each shooting object, whether the shooting objects are all people is detected, if the big tree is detected not to be people, judgment of interference objects can be carried out on the big tree, the interference objects do not exist in the view finding range at the moment, and the calculation amount is reduced.

When determining the position information of the interfering object relative to the mobile terminal from the image information, for example, a neural network model may be trained in advance, and the image information of the interfering object may be used as an input of the neural network model, so as to obtain the angle of the interfering object relative to the mobile terminal. When the neural network model is trained, sample images obtained by shooting objects positioned at different angles of the mobile terminal and the angles of the shooting objects relative to the mobile terminal are used as training samples to train the neural network model.
When the position information of the interfering object relative to the mobile terminal is determined according to the sound information, for example, the same piece of sound information collected by each microphone in the microphone group is processed, and the relative position of the sounding point relative to each microphone is calculated, so that the position of the sound source is determined, and the angle of the interfering object relative to the mobile terminal is obtained.
In some embodiments, when the microphone group collects sound information of a plurality of different interfering objects, sound information of each interfering object may be extracted from sound information mixed by the plurality of interfering objects using acoustic characteristics, spectral characteristics, and the like.
After the angle of each shooting object relative to the mobile terminal is determined, the target shooting object can be determined according to the angle of each shooting object relative to the mobile terminal and the characteristic information of the shooter.
In some embodiments, the characteristic information of the photographer includes at least one of face orientation information of the photographer and focus information of a line of sight on a display unit of the mobile terminal.
