Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the shooting method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 2, so that the shooting method may operate based on the android operating system shown in fig. 2. That is, the processor or the electronic device may implement the shooting method provided by the embodiment of the present invention by running the software program in the android operating system.
The following describes a shooting method according to an embodiment of the present invention with reference to a flow chart of the shooting method shown in fig. 3, where fig. 3 is a flow chart of the shooting method provided in the embodiment of the present invention, and the shooting method includes steps 301 to 302:
step 301: under the condition that a preview image acquired by a camera of the electronic equipment meets a preset condition, the electronic equipment controls the camera to move to a target position below the display screen.
In an embodiment of the present invention, the preview image acquired by the camera at least includes one of the following shooting objects: humans, animals, buildings, plants, etc.
In the embodiment of the invention, the preset conditions corresponding to different shooting objects in the preview image acquired by the camera are different.
Optionally, in an embodiment of the present invention, when the shooting object included in the preview image is a person, the condition that the preview image acquired by the camera meets the preset condition may include at least one of the following: the occupation ratio of the face area in the preview image of the electronic device is larger than a preset threshold (namely, the face shape does not accord with the preset face shape), or the position of the person in the preview image of the electronic device is not at a preset position (namely, the position of the person in the preview image does not accord with the preset shooting composition). The preset position may be the preset composition position.
Note that the preset position may be referred to as a preset composition position in the preview image. It can be understood that, when the shooting object in the preview image is at the preset composition position in the preview picture, the image effect of the preview image is good.
For example, the preset positions may be all positions corresponding to a photographing composition, and the preset positions may include: the position of a golden section line, or the position of a dividing line in a trisection pattern, etc. For example, the golden section line is a section line whose position in the preview image is determined based on the value of the golden section (0.618), so that the composition of the preview image is more aesthetically acceptable when the position of the subject is at the position of the section line.
For example, taking the preset position as the position of the golden section line as an example, when the photographic subject in the preview image is located on the left side of the golden section line in the preview image, in order to ensure that the photographic subject in the preview image can be located at the position of the golden section line, the electronic device needs to control the camera to move rightward at a constant speed, and when the photographic subject in the preview image moves to the position of the golden section line, the camera is controlled to stop moving (that is, the position of the camera is the target position), at this time, the photographic subject collected by the camera may present the best composition effect in the target image.
For example, in a case that a preview image acquired by a camera of the electronic device includes a human face, the electronic device may control movement of the camera by detecting proportion information of a human face region in the preview image (i.e., detecting a shape of the human face in the preview image) in the preview image, so as to change the proportion of the human face in the preview image until the proportion of the human face region in the preview image meets a preset threshold. For example, when the electronic device detects that the shape of the face in the preview image does not meet the preset shape, the electronic device changes the shape of the face in the preview image by adjusting the shooting angle of the camera until the shape of the face in the preview image meets the preset shape.
Optionally, in the embodiment of the present invention, after the camera of the electronic device acquires the preview image, shooting information of a shooting object in the preview image may be acquired. Wherein the shooting information of the shot object comprises at least one of the following items: position information of a photographic subject, contour information of the photographic subject, feature information of the photographic subject (for example, face feature information).
In a possible example, after the electronic device starts the camera, most users are not professional cameras and cannot ensure that a shot object shot by the electronic device is located at a preset composition position in a preview image, and in order to ensure that the electronic device can acquire a picture with a better shooting effect, the electronic device can adaptively control the camera to move to a target position below the display screen based on shooting information of the shot object by acquiring shooting information of the shot object in the preview image under the condition that the preview image acquired by the camera meets a preset condition.
In another possible example, after the electronic device starts the camera, if a shooting object to be shot is a dynamic object (e.g., a plant moving with wind, or a person in a motion state, etc.), since a position of the shooting object in the preview image continuously changes, a user cannot guarantee that the shooting object is located at a preset composition position in the preview image (i.e., a position of a person in the preview image of the electronic device is not located at the preset position), in order to guarantee that the electronic device can acquire a picture with a better shooting effect, in an embodiment of the present invention, shooting information of the shooting object in the preview image is obtained in real time, so that the electronic device can adaptively control the camera to move based on the shooting information of the shooting object.
Optionally, in the embodiment of the present invention, the controlling, by the electronic device, the movement of the camera may include at least one of: the shooting angle of the camera is controlled, the moving distance of the camera is controlled, and the moving direction of the camera is controlled. In an example, after the moving direction of the camera is determined, the electronic device may control the camera to move towards the corresponding moving direction until the camera moves to a target position below the display screen, so that the camera acquires an image with a good shooting effect at the target position.
Optionally, in the embodiment of the present invention, the electronic device may further detect a shooting angle of the camera in real time through a gyroscope inside the electronic device, so that the electronic device may determine an adjustment amount of the shooting angle based on the current shooting angle of the camera.
Step 302: and the electronic equipment displays the target image acquired by the camera at the target position.
In an embodiment of the present invention, the target image is an image including a photographic subject collected by a camera at a target position.
Optionally, in the embodiment of the present invention, in a case that a ratio of a face area in a preview image of the electronic device is greater than a preset threshold, the ratio of the face area in the target image is smaller than the preset threshold; and if the position of the person in the preview image of the electronic equipment is not at the preset position, the position of the person in the target image is at the preset position.
According to the shooting method provided by the embodiment of the invention, under the condition that the preview image acquired by the camera of the electronic equipment meets the preset condition, the electronic equipment controls the camera to move to the target position below the display screen, so that the electronic equipment displays the target image acquired by the camera at the target position. Therefore, the electronic equipment can control the camera to move based on the preview picture collected by the camera without manual control of a user, so that the moved camera can obtain an image with a better shooting effect, and the overall shooting efficiency is improved.
Optionally, in an embodiment of the present invention, in a case that a horizontal link and a vertical link are disposed below a display screen of the electronic device, and a camera is located at a connection position of the horizontal link and the vertical link, the step 301 may include the following step 301 a:
step 301 a: the electronic equipment controls the camera to move a first distance or rotate a first angle on the horizontal connecting rod and move a second distance or rotate a second angle on the vertical connecting rod.
Exemplarily, the first distance is a horizontal moving distance of the camera on the horizontal connecting rod; the second distance is a vertical moving distance of the camera on the vertical connecting rod. For example, if the position of the subject in the preview image is located on the left side of the preset composition position, the camera is controlled to move rightward, if the position of the subject in the preview image is located on the right side of the preset composition position, the camera is controlled to move leftward, if the position of the subject in the preview image is located on the upper side of the preset composition position, the camera is controlled to move downward, and if the position of the subject in the preview image is located on the lower side of the preset composition position, the camera is controlled to move upward.
For example, the electronic device may determine target offset information of the photographic object in the preview image by acquiring position information of the photographic object in the preview image according to the position information, and then determine a movement parameter of the camera according to the target offset information, so as to determine a movement distance or a rotation angle of the camera according to the movement parameter. Wherein the target offset information is: offset information between a position of the photographic subject in the preview image and a preset position of the preview image.
In one example, the target offset information includes horizontal offset information between horizontal position information of the photographic subject in the preview image and horizontal position information of a preset position of the preview image, and the electronic device may determine the horizontal movement distance according to the horizontal offset information.
In one example, the target offset information includes vertical offset information between vertical position information of the photographic subject in the preview image and vertical position information of a preset position of the preview image, and the electronic device may determine the vertical movement distance according to the vertical offset information.
In one example, after acquiring the position information of the photographic subject in the preview image (for convenience of explanation, the first position information is replaced below), the electronic device also acquires the position information which is closest to the photographic subject in the preview image and accords with the preset photographic composition (for convenience of explanation, the second position information is replaced below), then determines target offset information according to the first position information and the second position information, and finally controls the camera to move based on the movement parameter corresponding to the target offset information.
Specifically, the first position information may be a center line position of the photographic subject, and the second position information may be a position of a preset mapping line (for example, a position of a golden section line). At this time, the electronic apparatus controls the camera to move horizontally. If the x-axis coordinate of the center line position of the subject is x11, the x-axis coordinate of the position of the optimal mapping line is x22, and the offset information between the two is a, (x11-x22), the horizontal movement distance of the corresponding camera is an absolute value of x11-x22, and if a is a positive value, the horizontal movement direction of the camera is: and moving the camera to the negative direction of the x axis, wherein if a is a negative value, the horizontal moving direction of the camera is as follows: and moving the camera to the positive direction of the x axis.
For example, as shown in (a) of fig. 4, taking a shooting object as a person, when a center line (e.g. 42 in a) of a portrait in a preview image (e.g. 41 in fig. 4) of an electronic device is located at the right side of the preview image 41, and a golden section line (e.g. 43 in a in fig. 4) of the preview image 41 is located at the left side of the center line 42 of the portrait, the electronic device determines a horizontal movement distance S of the camera according to a horizontal distance difference L between the center line 42 of the portrait and the golden section line 43, and then controls the camera to move to the right by the distance S, and the portrait moves to the left correspondingly as the camera moves. As shown in fig. 4 (b), eventually, the portrait will be displayed at the position of the golden section line of the preview image, and at this time, the portrait in the captured image shows the best composition effect. It should be noted that the dotted lines in fig. 4 are used to assist in explaining the movement of the camera.
In one example, the first position information includes a first position coordinate (X1, y1), and the second position information includes a second position coordinate (X2, y2), based on which, for the X axis (i.e., horizontal direction), the electronic device shifts information X 'between the coordinates (X1, y1) and the coordinates (X2, y2) according to the coordinates (X1, y1) and the coordinates (X2, y2), i.e., (X1-X2), the horizontal moving distance of the corresponding camera is an absolute value of X1-X2, and if X' is a positive value, the horizontal moving direction of the camera is: moving the camera to the negative direction of the x axis, and if x' is a negative value, the horizontal moving direction of the camera is as follows: and moving the camera to the positive direction of the x axis. Similarly, for the Y axis (i.e. the vertical direction), the electronic device, based on the coordinates (x1, Y1) and (x2, Y2), has the offset information between them being Y ', i.e. (Y1-Y2), and the vertical movement distance of the corresponding camera is the absolute value of Y1-Y2, and if Y' is a positive value, the vertical movement direction of the camera is: and moving the camera to the negative direction of the y axis, wherein if y' is a negative value, the vertical moving direction of the camera is as follows: and moving the camera to the positive direction of the y axis.
In one example, when the position of the shooting object in the preview image is constantly changing, the electronic device may further adjust the position of the camera in real time according to the preview image collected by the camera. Therefore, the electronic equipment not only can enable the shooting object to be in a better composition position in the preview image, but also can enable the shooting object to keep a position stable effect in the preview image.
For example, in a case where the preview image includes a face of a subject, the photographing information includes face feature information of the subject, and the electronic device determines a movement parameter corresponding to the face feature information.
Illustratively, the face feature information may be used to indicate at least one of: the position of the center point of the face, the posture of the five sense organs and the contour of the face. In one example, the face feature information includes: face contour information, face center point coordinates and face five-sense feature information.
For example, the electronic device may determine the face shape from the face contour information.
Illustratively, different facial shapes correspond to different movement parameters.
For example, the electronic device obtains feature information of a face of a shooting object in a preview image, matches the feature information with feature information of a preset face shape, and further determines a movement parameter of the camera, and further, the electronic device moves the direction and distance of the camera according to the movement parameter. For example, the preset face shape includes: the face shape is melon seed face.
For example, taking the example that the face feature information is used to represent the positions of the eyes in the facial features and the preset photography composition is a trisection photography composition, after the electronic device acquires the position information of the eyes of the photographic object in the preview image, the electronic device determines the corresponding movement parameters according to the position information of the eyes and the position information of the intersection point of the three lines in the preview image.
For example, in the case where the preview image includes a face of a person of a photographic subject, a change in the angle and/or position of the camera may cause a change in the position and contour of the face in the preview image. For example, when the imaging angle of the camera is a depression angle (less than 90 °), the cheek portion of the face in the preview image becomes thin, and when the imaging angle of the camera is an elevation angle (more than 90 °), the cheek portion of the face in the preview image becomes wide.
For example, as shown in fig. 5 (a), when the electronic device detects that the contour of the cheek of the face of the photographic subject in the preview image (51 in fig. 5 (a)) is in a wide "square shape" (52 in fig. 5 (a)), and the user wants to photograph the face in the preview screen 51 as a thin face, the photographing angle of the camera needs to be adjusted so that the photographing angle of the camera is a depression angle. As shown in fig. 5 (b), when the shooting angle of the camera is changed, the outline of the face in the preview image is significantly reduced compared with the shooting angle of the camera which is not changed, and at this time, the face shape of the face in the preview image (53 in fig. 5 (b)) captured by the camera is changed from the previous "square shape" to the current "thin face shape" (54 in fig. 5 (b)).
Therefore, the electronic equipment determines the shooting angle, the moving direction and the moving distance of the camera according to the face shape of the human face, so that when a user shoots, the optimal face shape of a shot object in a preview image is ensured, and the shot image has a better effect.
