detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In the embodiment, a processing method of a photographing mode is provided. FIG. 1 is a flowchart of a processing method of a photographing mode according to an embodiment of the present invention. As shown in FIG. 1, the flow includes the following steps:

Step S102, determining an object symmetry axis of the object to be photographed;

Step S104, determining a filter symmetry axis in a symmetric filter photographing mode when photographing an object to be photographed according to an object symmetry axis;

Step S106, adjusting the symmetric filter photographing mode according to the determined filter symmetry axis.

In the shooting field of the camera, determining the symmetry axis of the object to be photographed, and determining the filter symmetry axis in the symmetrical filter photographing mode when the object to be photographed is photographed according to the symmetry axis of the object, wherein the object to be photographed may have one or more One or more axes of symmetry of the object to be photographed may be determined according to the similarity of the visual field (the similarity factor of texture, structure, shape, etc. in the image recognition algorithm), and the one or more axes of symmetry may be horizontal, vertical or inclined The axis of symmetry of the direction determines the axis of symmetry of the filter based on the one or more axes of symmetry, which may also be horizontal, vertical or oblique. When the symmetric filter photographing mode is adjusted according to the determined filter symmetry axis, when the filter symmetry axis is horizontal, the upper and lower symmetrical filter photographing mode is entered; when the filter symmetry axis is vertical, the left and right are entered. Symmetric filter photo mode; when the filter symmetry axis is tilted, enter the tilt symmetrical filter photo mode. Through the above steps, the symmetrical filter photographing mode in the related art can solve the symmetry shooting only on the fixed side of the object to be photographed, thereby causing a single technical problem of the symmetrical filter photographing mode function, thereby achieving the object according to the object to be photographed. Flexible adjustment of the effect of the symmetry axis in the filter photo mode improves user experience.

However, in the related art, when photographing is performed using the symmetric filter mode, only one side of the object to be photographed can be photographed symmetrically, but the symmetric image on the other side of the photographed object cannot be photographed. This is a pity, because many things in nature are not completely symmetrical. The tree will appear sparsely on the other side in the direction of the sun, and the left and right sides of the face are not completely symmetrical. For example, when using the current symmetric filter mode to shoot a human face, it is assumed that only a symmetrical image with the left face as a symmetrical element and a symmetrical image with the right face as a symmetrical element cannot be taken, but actually Some people will feel that their right face is more beautiful, and the symmetrical photo taken by the right face works well. When using the current symmetric filter mode to shoot trees, it is assumed that only a symmetrical image with a sparse side as a symmetrical element can be taken, and a symmetrical image with a dense side as a symmetrical element cannot be taken, but in reality, the right side can be shot. The symmetrical photos of the tree are more artistic.

Therefore, after the step S106, after the symmetrical filter photographing mode is adjusted according to the determined filter symmetry axis, the side of the object to be photographed may be directly photographed according to the adjusted symmetric filter photographing mode. In an optional embodiment, the method further includes: receiving the first touch signal after entering the adjusted symmetric filter photographing mode; determining the need according to the positional relationship between the position of the first touch signal and the axis of symmetry of the filter The image area of the object to be photographed that is mirrored; the image area of the object to be photographed that is mirrored according to the determined needs is adjusted to the symmetric filter photographing mode. In this optional embodiment, the image area of the object to be photographed that needs to be mirrored is optional, and is not limited to the images of the fixed upper side, the left side, and the like, so that the user can view the image of the current field of view. Selecting the side that meets the mind for mirroring improves the user experience.

Determining an image area of the object to be photographed that needs to be mirrored according to a positional relationship between a position of the received first touch signal and a symmetry axis of the filter, which may be: a position of the first touch signal on a side of the symmetry axis of the filter At the time, the axis of symmetry of the filter is centered, and the image of the side is mirrored by the image of the other side. In an optional embodiment, the method further includes: determining a first side display area of the filter symmetry axis in the symmetric filter photographing mode when the position of receiving the first touch signal is on the first side of the filter symmetry axis The image in the image is the image area of the object to be photographed that needs to be mirrored; in addition, the image area of the object to be photographed that is mirrored according to the determined need to adjust the symmetrical filter photographing mode can be implemented by the following steps, including: symmetrical filtering The second side display area of the filter symmetry axis in the mirror photographing mode is displayed as an image in the first side display area, wherein the second side is a side opposite to the first side with reference to the filter symmetry axis. In this alternative embodiment, the first touch signal is located on the first side, the image of the first side is retained, and the image of the other side is mirrored with reference to the first side image.

In each of the above embodiments, the first touch signal may be a pressure signal, a touch signal, a sliding track, or a combination thereof, as well as other common touch signals.

After adjusting the symmetric filter photographing mode in the image area of the object to be photographed mirrored according to the determined needs, the filter photographing can be directly performed according to the adjusted symmetric filter photographing mode. For example, when the symmetrical filter mode is used for photographing in the related art, when the distance and position between the camera and the object to be photographed remain unchanged, the displayed symmetrical image does not change, that is, the axis of symmetry of the camera field of view is The subject is relatively still. If you need to adjust the symmetrical picture, there are two ways: 1) the object being shot does not move, changing the position of the camera means changing the position of the symmetry axis of the field of view of the camera; 2) the position of the camera is not moving (the position of the symmetry axis of the field of view of the camera is unchanged), The object being shot changes position. This adjustment is very inconvenient.

In an optional embodiment, the image area that needs to be mirrored is adjusted in the case where the relative position of the camera and the object to be photographed is unchanged, and the symmetry may be performed on the axis of symmetry of the filter according to the determination. After the filter photographing mode performs the adjustment processing, receiving the second touch signal; 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; determining the mirror image to be required according to the adjusted relative position An image area of the object to be photographed; the image area of the object to be photographed that is mirrored according to the determined need to adjust the symmetric filter photographing mode. In this alternative embodiment, since the filter symmetry axis is generated according to the axis of symmetry of the object, the user may need to adjust the position of the automatically generated filter symmetry axis. In this alternative implementation, the second touch signal is implemented. Adjusting the relative position of the filter symmetry axis to the field of view image improves user experience and satisfaction.

The second touch signal may be a pressure signal, a touch signal, a sliding track, or a combination thereof. In an optional embodiment, the relative position of the filter symmetry axis and the displayed image of the object to be photographed is adjusted according to the second touch signal. The method may include: determining a moving direction of a position of the filter symmetry axis with respect to the displayed image of the object to be photographed according to the touch movement trajectory of the second touch signal; adjusting the filter symmetry axis and the displayed to be photographed according to the determined moving direction The relative position of the image of the object. In this optional embodiment, according to the touch movement trajectory of the second touch signal, the moving direction when the filter symmetry axis needs to be adjusted can be directly determined, and when the second touch signal stops sliding, the symmetry axis of the filter is stopped. Adjustment of the relative position of the object to be photographed. In this alternative embodiment, the camera and the object to be photographed may not move, and the adjustment of the area of the picture to be mirrored can be realized only by adjusting the relative position of the filter symmetry axis and the object to be photographed.

For example, in the upper and lower symmetric filter photographing mode, it is determined that the first touch signal is located on the lower side of the filter symmetry axis, and enters the lower symmetric filter photographing mode. At this time, when the upward touch movement track is detected, the filter symmetry is adjusted. Axis and object to be photographed The relative position of the filter makes the position of the symmetry axis of the filter unchanged, and displays the symmetrical image of the filter after the object to be photographed is moved down. For another example, in the left-right symmetric filter photographing mode, determining that the first touch signal is located on the left side of the filter symmetry axis, enters the left symmetric filter photographing mode, and at this time, detecting that the second touch signal moves to the left, the filter The axis of symmetry also moves to the left correspondingly, adjusting the area of the picture to be mirrored; if the second touch signal is detected to move to the right, the filter axis of symmetry also moves to the right.

Preferred embodiment 1

7 is a block diagram showing a preferred structure of an apparatus for implementing a symmetrical filter photographing mode using a pressure sensing technique. As shown in FIG. 7, the apparatus includes a pressure sensing module 72 (corresponding to the first receiving module 32 described above). Second connection The receiving module 52), the 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, the fourth determining module 56) and the screen The display module 76 (corresponding to the display unit 44 described above) will be described below.

The pressure sensing module 72 is attached to the lower portion of the screen display module 76. The function of detecting pressure is added to the existing screen display function. The filter processing module 74 is a core. When the user presses the screen hard, the pressure sensing module 72 The magnitude and position of the pressing pressure are detected, and the information data is transmitted to the filter processing module 74.

According to the above apparatus for realizing the symmetrical filter photographing mode by using the pressure sensing technology, a method for realizing the symmetrical filter photographing mode by using the pressure sensing technology in the embodiment of the present invention will be described. 8 is a flow chart of a method for implementing a symmetrical filter photographing mode using pressure sensing technology according to an embodiment of the present invention. As shown in FIG. 8, the flow includes the following steps:

Step S802, adaptive symmetric mode selection. When it is detected that the user enters the symmetrical filter photographing mode (the default is the left-right symmetric filter photographing mode as an example), according to the similarity of the visual field image (the similarity factor of texture, structure, shape, etc. in the image recognition algorithm), automatic detection or calculation If the axis of symmetry is vertical, the left-right symmetric filter photographing mode is maintained; if the symmetry axis is horizontal, it automatically changes to the upper and lower symmetrical filter photographing mode; if the symmetry axis is When tilted, it automatically changes to the tilt-symmetric filter photo mode. Moreover, the optimal approximate symmetry axis in the detected field of view is automatically taken as the initial display symmetry state of the preview on the screen, so that the optimal symmetry state in the field of view is automatically displayed, thereby reducing the manual adjustment operation of the user. Then, start monitoring the user's related touch operation to determine whether it meets the preset requirements.

In step S804, when the forced pressing is detected (ie, the pressing pressure of the contact point exceeds a pressure threshold), the position of the force pressing is determined to determine the symmetrical area. For example, when the pressed position is in the left half of the pressure screen, the left symmetric filter mode is triggered, that is, the middle line of the camera field of view is the axis of symmetry, and the middle line is symmetrically displayed with the left picture content as a symmetric area; When the pressed position is in the right half of the pressure screen, the right symmetric filter mode is triggered, that is, the middle line of the camera field of view is the axis of symmetry, and the middle line is symmetrically displayed in real time with the content of the right picture as a symmetric area. The same as the upper and lower symmetric filter mode and the oblique symmetric filter mode.

In step S806, the adjustable symmetric display mode is triggered. Taking the left (right) symmetric filter mode as an example, after determining the left (right) symmetric filter mode, continue to press hard. After more than one pressure value, as the pressure increases, the middle line of the camera field of view is right (left). When moving, the displayed symmetrical regions are also biased to the more right (left) side of the field of view, up to the extreme edge of the field of view. In addition to detecting the pressure only, you can forcefully press the left screen and slide to the right. When the middle line of the camera's field of view moves to the right, the displayed symmetrical areas are also shifted to the right side of the field of view until the rightmost position is displayed. Side view edge; press hard on the right side screen and slide to the left, then the middle line of the camera's field of view moves to the left, and the displayed symmetrical areas are also shifted to the left side of the field of view, respectively, until the leftmost view edge is displayed. Alternatively, you can slide to the left (right) at any position, and the middle line of the camera's field of view also moves to the left (right) accordingly. Similarly, in the upper symmetric filter mode, continue to press the upper (lower) side. After more than one pressure value, as the pressure increases, the middle line of the camera's field of view moves downward (upward), and the symmetric area is displayed. Also biased to the lower (upper) side of the field of view, respectively, up to the extreme edge of the field of view. Quickly double click to restore the initial symmetry state. The same is true for the tilt symmetric mode, and will not be described again.

In step S808, when the user finishes pressing hard, it indicates that the operation ends, and the photo preview screen does not change.

Preferred embodiment two

In the following, the device for realizing the symmetrical filter photo taking mode by using the pressure sensing technology is located in the mobile phone terminal as an example, and the tunable filter photographing mode in the mobile phone terminal is explained.

9 is a schematic diagram of adaptive symmetric mode selection according to an embodiment of the present invention. As shown in a of FIG. 9, a rectangular frame represents a screen display area of a mobile phone, and when the distance between the user and the position of the camera remains unchanged, the screen of the mobile phone is displayed. The area image is shown as a in Fig. 9.

When it is detected that the user enters the symmetric filter photographing mode (the default is the left-right symmetric filter photographing mode), the camera vision is automatically detected or calculated according to the similarity of the visual field image (the similarity factor of texture, structure, shape, etc. in the image recognition algorithm) The optimal approximate symmetry axis in the picture, if the symmetry axis is vertical, the left and right symmetrical filter photographing mode is maintained; if the symmetry axis is horizontal, it automatically changes to the upper and lower symmetrical filter photographing mode. Moreover, the optimal approximate symmetry axis in the detected field of view is automatically used as the initial display symmetry state of the preview on the screen, so that the optimal symmetry state in the field of view is automatically displayed, thereby reducing the manual adjustment operation of the user, as shown in FIG. As shown in b, it automatically enters the left and right symmetrical filter photo mode. The software system in the terminal starts to monitor the related touch operation of the user to determine whether it meets the preset requirement.

When the forced pressing is detected, the position of the force pressing is determined by the broken line L1 in b of FIG. 9 as the middle line of the screen. If the pressed position is in the left half of the pressure screen, the left symmetric filter mode is triggered, L1 The left picture content is symmetrically displayed in real time, and the preview result of the camera is shown as a in FIG. 11; if the pressed position is on the right half of the pressure screen, the right symmetric filter mode is triggered, and L1 is right. The picture content is symmetrically displayed in real time for the symmetric area, and the preview result of the camera is shown as b in FIG.

The position of the intermediate line L1 (b in Fig. 9) of the field of view of the camera is changed to change the display of the symmetrical area. Assuming that the left symmetrical filter mode is determined, the force is continuously pressed. After more than one pressure value, the adjustable symmetrical display mode is triggered. As the pressure increases, the middle line of the camera field of view moves to the right to the L2 position (a in FIG. 10). ), at this time, the image displayed on the screen is c in FIG. 11; when it continues to increase, the middle line of the camera field of view also moves to the right, when the middle line of the camera field of view moves to position 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, f in Fig. 11, and the right symmetry. In the filter mode, continue to press hard. After more than one pressure value, the adjustable symmetrical display mode is triggered. As the pressure increases, the middle line of the camera's field of view moves to the left, and the displayed symmetrical areas are also shifted to the left of the field of view. Side until it is displayed to the leftmost view edge. During the whole process, the user and the camera are relatively stationary, and the purpose of adjusting the symmetrical image on the screen can be achieved, the symmetry range is expanded, and a symmetrical image that cannot be displayed by the existing method can be obtained.

10 and 11 are only an exemplary illustration. In the left symmetric filter photographing mode, the middle line of the camera field of view can also be adjusted to move to the left, for example, by pressing in the left image area, so that the pressure value exceeds a certain threshold. Then, as the pressure increases, the relative position of the middle line of the camera's field of view to the object to be photographed can also move to the left. Alternatively, the touch may be continuously left to the left at any position on the screen. After the predetermined condition is reached, for example, the continuous touch time, the length of the touch track, and the like, the relative position of the middle line of the camera field of view and the object to be photographed may also move to the left.

In the process of adjusting the middle line of the camera field of view, the left and right frame positions of the screen are the field of view limit range. For example, in the case of the left symmetric filter photographing, when the control symmetry axis dashed line moves to the right, the right border of the screen of the symmetrical filter is not used, as shown by the dotted line of L5 in d in FIG. 10, which is the right axis of the symmetry axis. The extreme position, the displayed content in Fig. 11 is 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 case of the same right symmetrical filter, the content displayed on the left border of the screen without the symmetrical filter is the limit of the field of view in this mode. The dotted line symmetry axis mentioned here may or may not be displayed during actual processing. Preferably, it is not displayed on the screen, and it is a state of symmetry axis when the background data stream (each frame image) of the camera is processed in the background, which is controlled by the user but is not displayed, only to explain the symmetry. Figure 9 and Figure 10 are indicated by dashed lines; the user can see the symmetrical image on the screen which is still the axis of symmetry in the middle of the screen, but the content of the displayed symmetrical image changes with the control of the user's forced pressing. The user and the camera device are still. Alternatively, during the adjustment of the middle line of the camera field of view, the user can see the image in the field of view of the entire camera before the filter processing and the dotted line, which is convenient for the user to adjust.

When the user finishes pressing hard or the user ends the sliding touch, it indicates that the operation is over and the photo preview screen does not change.

The embodiment of the present invention is an example of a mobile phone terminal. In fact, the device for realizing the symmetrical filter photo taking by using the pressure sensing technology in the embodiment of the present invention can be applied to a photographing device of any symmetric filter photographing mode.

Preferred embodiment three

In this embodiment, another way of adjusting the filter symmetry axis within the field of view is provided.

When detecting that the user enters the symmetric filter photographing mode (the default is the left-right symmetric filter photographing mode), the camera vision image is automatically detected or calculated according to the similarity of the visual field image (the similarity factor of texture, structure, shape, etc. in the image recognition algorithm). The optimal approximate axis of symmetry.

When a forced pressing is detected (ie, the pressing pressure of the contact point exceeds a pressure threshold), the position where the force is pressed is positioned to determine the symmetrical area. For example, when the pressed position is in the left half of the pressure screen, the left symmetric filter mode is triggered, that is, the middle line of the camera field of view is the axis of symmetry, and the middle line is symmetrically displayed with the left picture content as a symmetric area; When the pressed position is in the right half of the pressure screen, the right symmetric filter mode is triggered, that is, the middle line of the camera field of view is the axis of symmetry, and the middle line is symmetrically displayed in real time with the content of the right picture as a symmetric area.

Trigger adjustable symmetrical display mode. After determining the left (right) symmetrical filter mode, the two fingers again press the screen at the same time and press to the right (left) to trigger the adjustable symmetrical display mode. Specifically, when the two fingers simultaneously press the screen and press hard to slide to the right, the middle line of the camera field of view moves to the right, and the displayed symmetrical areas are also shifted to the right side of the field of view, respectively, until the rightmost view edge is displayed; When the contact screen is pressed hard and slides to the left, then the middle line of the camera's field of view moves to the left, and the displayed symmetrical areas are also shifted to the left side of the field of view, respectively, until the leftmost field of view is displayed.

When the user presses hard, it indicates that the operation is over and the photo preview screen does not change.

The adjustment method of the filter symmetry axis in another imaging field of view in the embodiment of the present invention will be described below with reference to the accompanying drawings.

The position of the intermediate line L1 of the field of view of the camera is changed to change the display of the symmetrical area. Assume that the determination is a left symmetric filter mode After the formula. The two fingers again press the screen at the same time and press hard (detecting two contact points while pressing hard) and sliding to the right to trigger the adjustable symmetric display mode, and the middle line of the camera field of view moves to the right to L2 (a in Figure 10). At this time, the image displayed on the screen is c in FIG. 11; while continuing to slide, the middle line of the camera field of view also moves to the right, when the middle line of the camera field of view moves to position L3 (b in FIG. 10), L4 (FIG. 10). In the case of c) 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. Similarly, in the right symmetric filter mode, when the two fingers simultaneously touch the screen and press hard to slide to the left, then the middle line of the camera's field of view moves to the left, and the displayed symmetrical areas are also biased to the left of the field of view, respectively, until the display The leftmost view edge. During the whole process, the user and the camera are relatively stationary, and the purpose of adjusting the symmetrical image on the screen can be achieved, the symmetry range is expanded, and a symmetrical image that cannot be displayed by the existing method can be obtained.

The limitations, as well as the cumbersome operation of changing the symmetrical content of the display, can only change the relative position of the camera to the object being photographed. In the embodiment of the present invention, the user can control the other side of the display display symmetry by one-finger press or two-finger press, slide or other control mode, and the symmetrical content displayed by the user can be adjusted when the camera and the object are both stationary. , the scope of symmetry is expanded, and different contents can be displayed symmetrically.
