Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In the present embodiment, a method for processing a photographing mode is provided, and fig. 1 is a flowchart of the method for processing the photographing mode according to the embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
step S102, determining an object symmetry axis of an object to be shot;
step S104, determining a filter symmetry axis in a symmetric filter photographing mode when an object to be photographed is photographed according to the object symmetry axis;
and step S106, adjusting the symmetrical filter photographing mode according to the determined filter symmetry axis.
In a shooting view of a camera, determining an object symmetry axis of an object to be shot, and determining a filter symmetry axis in a symmetric filter shooting mode when the object to be shot is shot according to the object symmetry axis, wherein the object to be shot may have one or more symmetric axes, the one or more symmetric axes of the object to be shot may be determined according to view picture similarity (similarity factors such as texture, structure, shape and the like in an image recognition algorithm), the one or more symmetric axes may be a symmetric axis in a horizontal, vertical or oblique direction, the filter symmetry axis is determined according to the one or more symmetric axes, and the filter symmetry axis may also be in the horizontal, vertical or oblique direction. When the symmetrical filter photographing mode is adjusted according to the determined filter symmetry axis, entering an up-down symmetrical filter photographing mode when the filter symmetry axis is in the horizontal direction; when the symmetry axis of the filter is in the vertical direction, entering a left-right symmetrical filter photographing mode; and when the symmetry axis of the filter is in the inclined direction, entering an inclined symmetrical filter photographing mode. Through the steps, the technical problem that in the related art, the fixed side of the object to be photographed can only be symmetrically photographed according to the configuration in the symmetrical filter photographing mode, so that the symmetrical filter photographing mode is single in function is solved, the effect of flexibly adjusting the symmetry axis in the filter photographing mode according to the object to be photographed is achieved, and the user experience is improved.
However, in the related art, when the photographing is performed in the symmetric filter mode, only one side of the photographed object can be photographed symmetrically, but a symmetric image of the other side of the photographed object cannot be photographed. Unfortunately, because many things in nature are not completely symmetrical, the tree has the phenomenon that one side of the tree is sparse and the other side of the tree is dense along with the direction of sunlight, and the left side and the right side of the face are not completely symmetrical. For example, when a human face is photographed using the conventional symmetric filter pattern, if only a symmetric image with a left face as a symmetric element is photographed and a symmetric image with a right face as a symmetric element is not photographed, there is a possibility that a person may actually feel that his or her right face is beautiful and a symmetric photograph photographed with the right face is effective. When the existing symmetrical filter mode is used for shooting trees, if only a symmetrical image with a sparse side as a symmetrical element can be shot and a symmetrical image with a dense side as a symmetrical element cannot be shot, a symmetrical photo of a tree possibly shot at the dense side on the right side is more artistic in practice.
Therefore, after the step S106, after the adjustment processing is performed on the symmetric filter photographing mode according to the determined filter symmetry axis, the filter photographing can be directly performed on one side of the object to be photographed according to the adjusted symmetric filter photographing mode. In an optional embodiment, the method may further include: after entering the adjusted symmetrical filter photographing mode, receiving a first touch signal; determining an image area of an object to be photographed, which needs to be mirrored, according to the position relation between the position of receiving the first touch signal and the filter symmetry axis; and adjusting the symmetrical filter photographing mode according to the determined image area of the object to be photographed needing to be mirrored. In the optional embodiment, the image area of the object to be shot, which needs to be mirrored, is optional and is not limited to the images of the fixed upper side, left side and other areas, so that the user can select the side meeting the mind to be mirrored according to the image condition of the current shooting view field, and the experience degree of the user is improved.
Determining an image area of the object to be photographed, which needs to be mirrored, according to a position relationship between the position of the received first touch signal and a filter symmetry axis, where the determining may be: and when the position of the first touch signal is positioned at one side of the filter symmetry axis, taking the filter symmetry axis as a central symmetry axis, and performing mirror image processing on the image at the side by referring to the image at the other side. In an optional embodiment, the method may further include: when the position for receiving the first touch signal is located on the first side of the filter symmetry axis, determining an image in a display area on the first side of the filter symmetry axis in the symmetric filter photographing mode as an image area of an object to be photographed, wherein the image area needs to be mirrored; in addition, the adjustment of the symmetrical filter photographing mode according to the determined image area of the object to be photographed, which needs to be mirrored, can be realized by adopting the following steps: and displaying the image in the first side display area in a second side display area of the filter symmetry axis in the symmetric filter photographing mode, wherein the second side is the side opposite to the first side with the filter symmetry axis as a reference. In this alternative embodiment, if the first touch signal is located on the first side, the image on the first side is retained, and the image on the other side is mirrored with reference to the image on the first side.
In the above embodiments, the first touch signal may be a pressure signal, a point touch signal, a sliding track, or a combination thereof, and other common touch signals.
After the symmetrical filter photographing mode is adjusted according to the determined image area of the object to be photographed, which needs to be mirrored, the filter photographing can be directly performed according to the adjusted symmetrical filter photographing mode. For example, when photographing is performed using the symmetric filter mode in the related art, when the distance and position between the camera and the subject remain unchanged, the displayed symmetric image also does not change, i.e., the axis of symmetry of the field of view of the camera and the subject are relatively stationary. If the symmetric picture needs to be adjusted, there are two ways: 1) the shot object is fixed, and the position of the camera is changed, namely the position of a symmetry axis of the visual field of the shooting camera is changed; 2) the camera position is fixed (the symmetrical axis position of the camera visual field is not changed), and the shot object changes position. This is inconvenient to adjust.
In an optional embodiment, under the condition that the relative position between the camera and the object to be photographed is not changed, the image area needing mirror image is adjusted, and a second touch signal can be received after the symmetrical filter photographing mode is adjusted according to the determined filter symmetry axis; adjusting the relative position of the filter symmetry axis and the displayed image of the object to be shot according to the second touch signal; determining an image area of the object to be shot, which needs to be mirrored, according to the adjusted relative position; and adjusting the symmetrical filter photographing mode according to the determined image area of the object to be photographed, which needs to be mirrored. In this optional embodiment, since the filter symmetry axis is generated according to the object symmetry axis, the user may need to adjust the position of the automatically generated filter symmetry axis, and this optional implementation realizes adjustment of the relative position of the filter symmetry axis with respect to the view field image according to the second touch signal, thereby improving user experience and satisfaction.
The second touch signal may be a pressure signal, a point touch signal, a sliding track, or a combination thereof, and in an alternative embodiment, adjusting the relative position of the filter symmetry axis and the displayed image of the object to be photographed according to the second touch signal may include: determining the moving direction of the filter symmetry axis relative to the position of the displayed image of the object to be shot according to the touch moving track of the second touch signal; and adjusting the relative position of the filter symmetry axis and the displayed image of the object to be shot according to the determined moving direction. In this optional embodiment, according to the touch movement trajectory of the second touch signal, the movement direction of the filter symmetry axis when adjustment is required may be directly determined, and when the second touch signal stops sliding, adjustment of the relative position of the filter symmetry axis and the object to be photographed is stopped. In this optional embodiment, both the camera and the object to be photographed may not move, and the adjustment of the region of the picture to be mirrored may be achieved only by adjusting the relative position of the filter symmetry axis and the object to be photographed.
For example, in the up-down symmetrical filter shooting mode, it is determined that the first touch signal is located at the lower side of the filter symmetry axis, the down-symmetrical filter shooting mode is entered, at this time, an upward touch movement trajectory is detected, the relative position of the filter symmetry axis and the object to be shot is adjusted, the position of the filter symmetry axis is unchanged, and a filter symmetrical image after the object to be shot moves down is displayed. For another example, in the bilateral symmetry filter photographing mode, it is determined that the first touch signal is located on the left side of the filter symmetry axis, and the left symmetry filter photographing mode is entered, at this time, when the second touch signal is detected to move to the left, the filter symmetry axis also correspondingly moves to the left, and the area of the picture to be mirrored is adjusted; if the second touch signal is detected to move to the right, the filter symmetry axis correspondingly moves to the right.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

In this embodiment, a combination of the first touch signal as a pressure signal, the second touch signal as a pressure signal, and the touch signal is described as an example.
In the related art, when a symmetrical filter mode is used for photographing, only one side of a photographed object can be symmetrically photographed, but a symmetrical image of the other side of the photographed object cannot be photographed; when the symmetric picture needs to be adjusted, at least one of the camera and the opposite shooting object needs to be moved to change the position so as to adjust the display content of the symmetric picture. In order to solve the technical problem of single function of the filter photographing mode in the related art, embodiments of the present invention provide a method and an apparatus for implementing an adjustable symmetric filter photographing mode by using a pressure sensing technology (i.e., a method and an apparatus for processing a photographing mode in the above embodiments).
Fig. 7 is a block diagram of a preferred structure of an apparatus for implementing an adjustable symmetrical filter photographing mode by using a pressure sensing technology according to an embodiment of the present invention, and as shown in fig. 7, the apparatus includes a pressure sensing module 72 (corresponding to the first receiving module 32 and the second receiving module 52), a filter processing module 74 (corresponding to the first determining module 22, the second determining module 24, the processing module 26, the third determining module 34, the second adjusting module 54, and the fourth determining module 56), and a screen display module 76 (corresponding to the display unit 44), which will be described below.
The pressure sensing module 72 is attached below the screen display module 76, and adds a pressure detection function on the basis of the existing screen display function; the filter processing module 74 is a core, when a user presses the screen hard, the pressure sensing module 72 detects the size and position of the pressing pressure, transmits the information data to the filter processing module 74, the filter processing module 74 processes the data according to the designed software algorithm, and transmits the processed data to the screen display module 76 in real time for image display.
According to the device for realizing the adjustable symmetrical filter photographing mode by using the pressure sensing technology, the method for realizing the adjustable symmetrical filter photographing mode by using the pressure sensing technology in the embodiment of the invention is explained. Fig. 8 is a flowchart of a method for implementing a photographing mode with adjustable symmetric filter by using pressure sensing technology according to an embodiment of the present invention, as shown in fig. 8, the flowchart includes the following steps:
step S802, adaptive symmetry mode selection. When detecting that a user enters a symmetrical filter shooting mode (taking default as a bilateral symmetrical filter shooting mode as an example), automatically detecting or calculating an optimal approximate symmetry axis in a camera visual field picture according to visual field picture similarity (similarity factors such as textures, structures, shapes and the like in an image recognition algorithm), and if the symmetry axis is in a vertical direction, keeping the bilateral symmetrical filter shooting mode; if the symmetry axis is in the horizontal direction, automatically changing to an up-down symmetrical filter lens photographing mode; if the symmetry axis is in the inclined direction, the photographing mode of the inclined symmetrical filter lens is automatically changed. And the detected optimal approximate symmetry axis in the visual field is automatically used as the initial display symmetry state of the preview on the screen, so that the optimal symmetry state in the visual field is automatically displayed, and the manual adjustment operation of a user is reduced. And then, starting to monitor the related touch operation of the user and judging whether the related touch operation meets the preset requirement.
In step S804, when the pressing force is detected (i.e. the pressing pressure of the contact point exceeds a pressure threshold), the position of the pressing force is located, and the symmetric region is determined. For example, when the position pressed with force is positioned at the left half side of the pressure screen, a left symmetrical filter mode is triggered, namely the middle line of the visual field of the camera is taken as a symmetrical axis, and the middle line is symmetrically displayed in real time by taking the left picture content as a symmetrical area; when the position pressed with force is on the right half of the pressure screen, the right symmetrical filter mode is triggered, namely the middle line of the camera visual field is taken as a symmetrical axis, and the middle line is symmetrically displayed in real time by taking the right picture content as a symmetrical area. The same applies to the up-down symmetrical filter mode and the tilted symmetrical filter mode.
Step S806, triggering the adjustable symmetric display mode. Taking the left (right) symmetric filter mode as an example, after the left (right) symmetric filter mode is determined, pressing is continuously performed, after a pressure value is exceeded, the middle line of the camera visual field moves to the right (left) along with the increase of the pressure, and the displayed symmetric areas also respectively deviate to the more right (left) side of the visual field until the most edge of the visual field. In addition to detecting and sensing only pressure, the left screen can be pressed forcibly and slides rightwards, the middle line of the visual field of the camera moves rightwards, and the displayed symmetrical areas also deflect to the more right side of the visual field respectively until the edge of the rightmost visual field is displayed; the right screen is pressed with force and slides to the left, then the middle line of the camera view moves to the left, and the displayed symmetrical areas also respectively lean to the left of the view until the leftmost edge of the view is displayed. Alternatively, the camera may be slid to the left (right) at any one position, and the middle line of the camera view is moved to the left (right) accordingly. Similarly, in the upper symmetric filter mode, the upper (lower) side is continuously pressed with force, after a pressure value is exceeded, the middle line of the visual field of the camera moves downwards (upwards) along with the increase of the pressure, and the displayed symmetric regions also respectively deviate to the lower (upper) side of the visual field until the edge of the visual field is the most. A quick double click restores the initial symmetric state. The same processing manner is also used for the tilt symmetry mode, and the description is omitted here.
Step S808, when the user finishes pressing hard, indicating that the operation is finished, and the photo preview screen does not change.

Fig. 9 is a schematic diagram of adaptive symmetric mode selection according to an embodiment of the present invention, where as shown in a in fig. 9, a rectangular box represents a display area of a mobile phone screen, and when a distance between a user and a position of a camera remains unchanged, an image of the display area of the mobile phone screen is shown in a in fig. 9.
When detecting that a user enters a symmetrical filter photographing mode (default is a left-right symmetrical filter photographing mode), automatically detecting or calculating an optimal approximate symmetry axis in a camera view picture according to the view picture similarity (similarity factors such as textures, structures, shapes and the like in an image recognition algorithm), and if the symmetry axis is in a vertical direction, keeping the left-right symmetrical filter photographing mode; if the symmetry axis is in the horizontal direction, the photographing mode of the up-down symmetrical filter is automatically changed. And automatically taking the detected optimal approximate symmetry axis in the visual field as the initial display symmetry state of the preview on the screen, thus automatically displaying the optimal symmetry state in the visual field, reducing the manual adjustment operation of the user, and automatically entering the left-right symmetry filter photographing mode as shown in b in fig. 9. And a software system in the terminal starts to monitor the related touch operation of the user and judges whether the related touch operation meets the preset requirement.
When the hard pressing is detected, taking a broken line L1 in b in fig. 9 as a middle line of the screen, locating the position of the hard pressing, and if the position of the hard pressing is at the left half side of the pressure screen, triggering a left symmetric filter mode, wherein L1 performs real-time symmetric display by taking the left picture content as a symmetric region, and the camera preview display result is shown as a in fig. 11; if the position pressed hard is on the right half of the pressure screen, the right symmetric filter mode is triggered, the right picture content is used as a symmetric region for real-time symmetric display by the L1, and the camera preview display result is shown as b in fig. 11.
The position of the middle line L1 (b in fig. 9) of the camera view is changed to change the display of the symmetric region. Assuming that after the left symmetric filter mode is determined, pressing is continuously performed, and after a pressure value is exceeded, an adjustable symmetric display mode is triggered, and as the pressure is increased, the middle line of the camera view field moves to the right to the position L2 (a in FIG. 10), at this time, the image displayed on the screen is c in FIG. 11; and when the middle line of the camera view field is moved to positions L3 (b in FIG. 10), L4 (c in FIG. 10) and L5 (d in FIG. 10), the images displayed on the corresponding preview screen are d in FIG. 11, e in FIG. 11 and f in FIG. 11 respectively. In the whole process, the user and the camera are relatively static, so that the aim of adjusting the effect of the symmetrical image on the screen can be fulfilled, the symmetrical range is expanded, and the symmetrical image which cannot be displayed by the existing method can be obtained.
Fig. 10 and fig. 11 are only an exemplary illustration, and in the left symmetric filter photographing mode, the middle line of the camera view field may also be adjusted to move to the left, for example, after the left image area is pressed, so that the pressure value exceeds a certain threshold value, as the pressure increases, the relative position between the middle line of the camera view field and the object to be photographed may also move to the left. Or, the touch may be continuously performed to the left at any position on the screen, and after a predetermined condition is reached, such as the continuous touch time, the touch track length, and the like, the relative position between the middle line of the camera view and the object to be photographed may also be moved to the left.
In the process of adjusting the middle line of the camera view, the left and right frames of the screen are positioned in the view limit range. For example, in the case of left-symmetric filter photographing, when the dashed line of the symmetry axis is controlled to move to the right, the right frame of the screen of the symmetric filter is not used, such as the dashed line position of L5 in d in fig. 10, which is the limit position of the right movement of the symmetry axis, and f in fig. 11 is displayed as the limit content of the left-symmetric filter mode, that is, f in fig. 11 is the limit adjustable display at this time. In the same way, under the condition of photographing by using the right symmetric filter, the content displayed by the left frame of the screen without using the symmetric filter is the content of the visual field limit in the mode. The axis of symmetry of the dotted line referred to here may or may not be displayed in the actual process. Preferably, it is not displayed on the screen, and it is the state of the symmetry axis when the background processes each frame data stream (each frame image) of the camera in preview, controlled by the user but not displayed, and only for explaining the symmetry situation is indicated by the dotted line in fig. 9 and 10; the user can see the symmetrical image on the screen which still takes the middle of the screen as the symmetry axis, and only along with the control of the user pressing hard, the content of the displayed symmetrical image is changed, and the user and the photographing device are still. Or, in the process of adjusting the middle line of the camera view field, the user can see the image and the dotted line in the whole camera view field before the filter processing, so that the user can conveniently adjust.
And when the user finishes pressing hard or the user finishes sliding touch, the operation is finished, and the picture-taking preview picture is not changed any more.
In the embodiment of the invention, a mobile phone terminal is taken as an example, and in fact, the device for realizing adjustable symmetrical filter shooting by using the pressure sensing technology in the embodiment of the invention can be applied to any shooting equipment with symmetrical filter shooting mode.
Preferred embodiment three
In this embodiment, another way of adjusting the filter symmetry axis in the field of view of the image capture is provided.
When detecting that a user enters a symmetrical filter shooting mode (the default mode is a left-right symmetrical filter shooting mode), automatically detecting or calculating the optimal approximate symmetry axis in the camera view picture according to the view picture similarity (similarity factors such as textures, structures, shapes and the like in an image recognition algorithm).
When the pressing force is detected (namely the pressing pressure of the contact point exceeds a pressure threshold), the position of the pressing force is positioned, and the symmetrical area is determined. For example, when the position pressed with force is positioned at the left half side of the pressure screen, a left symmetrical filter mode is triggered, namely the middle line of the visual field of the camera is taken as a symmetrical axis, and the middle line is symmetrically displayed in real time by taking the left picture content as a symmetrical area; when the position pressed with force is on the right half of the pressure screen, the right symmetrical filter mode is triggered, namely the middle line of the camera visual field is taken as a symmetrical axis, and the middle line is symmetrically displayed in real time by taking the right picture content as a symmetrical area.
Triggering an adjustable symmetric display mode. After the left (right) symmetrical filter mode is determined, the two fingers are simultaneously contacted with the screen again to press forcibly and slide rightwards (left), and then the adjustable symmetrical display mode is triggered. Specifically, when the two fingers are pressed forcibly and slide rightwards by contacting the screen at the same time, the middle line of the visual field of the camera moves rightwards, and the displayed symmetrical areas also deflect to the more right side of the visual field respectively until the rightmost visual field edge is displayed; the two fingers are pressed forcibly and slide leftwards by contacting the screen at the same time, then the middle line of the visual field of the camera moves leftwards, and the displayed symmetrical areas also deflect to the left side of the visual field respectively until the edge of the visual field at the leftmost side is displayed.
And when the user finishes pressing hard, the operation is finished, and the picture-taking preview picture is not changed any more.
Another method for adjusting the symmetry axis of the filter in the imaging field of view according to the embodiment of the present invention will be described below with reference to the drawings.
The position of the middle line L1 of the camera field of view is changed to change the display of the symmetric region. Assume that the left symmetric filter pattern is determined. The two fingers touch the screen again and press hard (detect that two contact points press hard at the same time) and slide to the right, triggering an adjustable symmetrical display mode, and moving the middle line of the camera view to the right to the position L2 (a in FIG. 10), so that the image displayed on the screen at this time is c in FIG. 11; the middle line of the camera view is also moved rightward by the continued sliding, and when the middle line of the camera view is moved to the positions L3 (b in fig. 10), L4 (c in fig. 10), L5 (d in fig. 10), the images displayed on the corresponding preview screens are d in fig. 11, e in fig. 11, and f in fig. 11, respectively. In a right symmetrical filter mode, the two fingers are pressed forcibly and slide leftwards by contacting the screen at the same time, so that the middle line of the visual field of the camera moves leftwards, and the displayed symmetrical areas are also deflected to the left side of the visual field respectively until the edge of the visual field at the leftmost side is displayed. In the whole process, the user and the camera are relatively static, so that the aim of adjusting the effect of the symmetrical image on the screen can be fulfilled, the symmetrical range is expanded, and the symmetrical image which cannot be displayed by the existing method can be obtained.
The operation method for switching the symmetrical direction and adjusting the symmetrical content when the symmetrical filter is pressed down by force in the embodiment of the invention solves the problems that the symmetrical filter photographing mode in the related technology can only be limited by one side of the object to be photographed symmetrically, and the complicated operation that the displayed symmetrical content can only be changed by changing the relative position of the camera and the object to be photographed. The embodiment of the invention can be pressed by a single finger of a user or pressed by two fingers, slid or in other control modes, namely, the other symmetrical side can be controlled and switched to be displayed, and the user can adjust the displayed symmetrical content when the camera and the shot object are both static, thereby expanding the symmetrical range and symmetrically displaying different contents. The function is practical and easy to operate.
