Or prioritization. It should be understood that the objects so described are interchangeable where appropriate. Moreover, the terms "comprising" and "having" and "the" are intended For example, a process, method, or a device, terminal, or system comprising a series of modules or units is not necessarily limited to those steps or modules or units that are clearly listed, and may include steps that are not explicitly listed or Modules or units may also include other steps or modules or units inherent to such processes, methods, apparatus, terminals or systems.

The embodiment of the invention provides a photographing composition method, device and electronic device, which will be respectively described in detail below.

As shown in FIG. 1 , the photo composition method may include the following steps:

S110. Acquire image information in the frame.

Among them, the photo composition method can be applied to electronic devices such as digital cameras and smart phones. The electronic device has a camera and a framing frame. The camera is used to capture image information in the external environment. The image information captured by the camera can be displayed in the viewfinder. When the smartphone implements the camera function, the image information collected by the camera can be displayed on the display screen. At this point, the display of the smartphone acts as a framing frame.

During the photographing process, the user can observe the image information collected by the camera in real time through the framing frame, thereby adjusting the position and angle of the camera to obtain a better photographing effect.

During the photographing process, the electronic device can acquire image information displayed in the finder frame and analyze and process the image information.

In an actual application, the electronic device can obtain image information of the framing frame once every interval. For example, image information can be acquired once per second.

S120. Analyze the image information to extract main features in the image information.

After the electronic device acquires the image information in the finder frame, the image information is analyzed to extract the main features in the image information. Image information typically includes a main feature and a background. Among them, the main feature is the feature that the user wants to highlight during the photographing process, such as characters, buildings, animals, and the like. The background is the environmental information around the main feature. Referring to FIG. 5, the image information displayed in the finder frame includes a main feature and a background, and the main feature is a character.

In some embodiments, as shown in FIG. 2, before acquiring the image information in the finder frame, the photo composition method may further include the following steps:

S150, applying a convolutional neural network to train an image information analysis model;

The image information is analyzed to extract main features in the image information, including:

S121. Analyze the image information by using the image information analysis model to extract main features in the image information.

Among them, Convolutional Neural Network (Convolutional Neural Network) Network, CNN) is a feedforward neural network that can be used to process images. Processing images using convolutional neural networks is a mature technology.

In the embodiment of the present invention, the convolutional neural network may be applied to train the image information analysis model, and the image information analysis model is stored in the electronic device. The image information analysis model is used to analyze and identify images. After acquiring the image information, the electronic device calls the image information analysis model stored in the electronic device to analyze the image information to extract the main features in the image information.

S130, a Fibonacci spiral is established in the framing frame.

Among them, the Fibonacci spiral is also called the "golden spiral", which is a spiral curve drawn according to the Fibonacci sequence, along which a plurality of rectangles are distributed.

After the electronic device extracts the main features in the image information, a Fibonacci spiral can then be created in the framing frame.

In some embodiments, as shown in FIG. 2, before the Fibonacci spiral is established in the finder frame, the photo composition method may further include:

S160. Determine whether the main feature extraction is successful.

The electronic device may compare the plurality of main features extracted in a period of time to determine the similarity between the plurality of main features in the time period. When the similarity between each two adjacent main features is greater than the preset value, the main feature extraction is considered to be successful, otherwise the main feature extraction is considered unsuccessful. The preset value may be a preset value, for example, 70%. When the main feature extraction is successful, step S130 is performed; when the main feature extraction is unsuccessful, step S161 is performed.

For example, when the electronic device extracts the main feature once per second, the five main features extracted within 5 seconds may be compared to determine the similarity between the five main features. When the similarity between each two adjacent main features of the five main features is greater than 70%, the main feature extraction is considered to be successful.

S161, if the main feature extraction is unsuccessful, receiving a touch operation of the user on the finder frame;

S162. Determine an area corresponding to the touch operation in the image information as a main feature.

The viewfinder frame of the electronic device can integrate the touch sensing function, that is, the viewfinder frame can be a touch screen. When the electronic device determines that the main feature extraction is unsuccessful, the user may be prompted to specify the main feature in the finder frame. For example, the text message "Please specify the main feature in the image information" can be displayed in the finder frame to prompt the user.

Subsequently, the electronic device receives a touch operation of the user on the finder frame, and determines an area of the image information corresponding to the touch operation as a main feature. The user's touch operation may be a click operation or a sliding operation. After the electronic device determines the main feature, step S130 is subsequently performed.

In some embodiments, as shown in FIG. 3, establishing a Fibonacci spiral in the finder frame includes the following steps:

S131, respectively establishing a horizontal reference line and a vertical reference line in a horizontal direction and a longitudinal direction of the finder frame;

S132, determining an intersection of the horizontal reference line and the vertical reference line as an origin;

S133, the Fibonacci spiral is established in the framing frame starting from the origin.

Referring to FIG. 6, it can be understood that the horizontal and vertical directions of the finder frame are the horizontal side and the vertical side of the finder frame, respectively. The preset ratio can be a preset value. The preset ratio is greater than 0 and less than 1.

For human vision, when an object is divided into two parts in a golden section, these two parts have a strong aesthetic. Therefore, in practical applications, the above preset ratio may be a golden ratio (the golden ratio is about 0.618).

The electronic device can establish lateral reference lines and longitudinal reference lines in the horizontal and vertical directions of the framing frame, respectively, in a golden section. Among them, the horizontal reference line divides the framing frame into upper and lower parts, and the ratio of the lower part to the upper part is the golden ratio. The vertical reference line divides the framing frame into two parts, and the ratio of the left half to the right half is the golden ratio.

Subsequently, the intersection O of the lateral reference line and the longitudinal reference line is determined as the origin, and the Fibonacci spiral is established in the finder frame starting from the origin.

In the process of establishing the Fibonacci spiral, you can first establish a Cartesian coordinate system with O as the origin, the horizontal reference line as the X axis, and the vertical reference line as the Y axis. Then, the Fibonacci spiral is established by taking the values in the Fibonacci sequence as the straight line in the direction of -Y, -X, +Y, and +X. The final Fibonacci spiral is shown in Figure 7.

In some embodiments, as shown in FIG. 4, determining the intersection of the lateral reference line and the longitudinal reference line as the origin includes the following steps:

S1321, respectively, establishing a horizontal center line and a longitudinal center line along a lateral direction and a longitudinal direction of the finder frame, wherein the horizontal center line and the longitudinal center line divide the finder frame into four areas;

S1322, determining an area where the main feature is located as a starting area;

S1323, determining an intersection of the horizontal reference line and the vertical reference line in the starting area as an origin.

Referring to FIG. 8, the number of horizontal reference lines established by the electronic device is two, and the number of vertical reference lines is also two. The ratio of the lower region to the upper region of the lateral reference line 1 is a golden ratio, and the ratio of the upper region to the lower region of the lateral reference line 2 is a golden ratio. The ratio of the left region to the right region of the longitudinal reference line 1 is a golden ratio, and the ratio of the right region to the left region of the longitudinal reference line 2 is a golden ratio. The two lateral reference lines and the two longitudinal reference lines form four intersections A, B, C, D.

In this embodiment, the electronic device establishes a horizontal center line and a longitudinal center line along the lateral direction and the longitudinal direction of the finder frame, respectively. The horizontal center line divides the framing frame into upper and lower halves. The vertical center line divides the framing frame into left and right halves. The horizontal center line and the vertical center line divide the framing frame into four areas: the lower left area, the upper left area, the upper right area, and the lower right area. Among them, the intersection point A is located in the lower left area, the intersection point B is located in the upper left area, the intersection point C is located in the upper right area, and the intersection point D is located in the lower right area.

The electronic device can determine which region the main feature extracted in step S120 is in and determine the region as the starting region. When the main feature spans a plurality of regions, for example, the main feature spans the lower left region and the upper left region, the region in which most of the main feature is located is determined as the start region.

Subsequently, the intersection of the lateral reference line and the longitudinal reference line in the starting area is determined as the origin.

In the process of establishing the Fibonacci spiral, the electronic device can establish a Cartesian coordinate system with the horizontal reference line in the starting area as the X axis and the vertical reference line as the Y axis, and the determined origin.

When the intersection A is the origin, the Fibonacci spiral is established by sequentially taking the values in the Fibonacci sequence as the straight line in the direction of -Y, -X, +Y, and +X. The final Fibonacci spiral is shown in Figure 7.

When the intersection point B is the origin, the Fibonacci spiral is established by sequentially taking the values in the Fibonacci sequence as the straight line in the directions of +Y, -X, -Y, and +X. The final Fibonacci spiral is shown in Figure 9.

When the intersection point C is the origin, the Fibonacci spiral is established by sequentially taking the values in the Fibonacci sequence as the straight line in the direction of +Y, +X, -Y, and -X. The final Fibonacci spiral is shown in Figure 10.

When the intersection D is the origin, the Fibonacci spiral is established by sequentially taking the values in the Fibonacci sequence as the straight line in the direction of -Y, +X, +Y, and -X. The final Fibonacci spiral is shown in Figure 11.

It should be noted that the embodiment of the present invention is described herein only by taking the lateral length of the finder frame as being larger than the longitudinal length. When the lateral length of the finder frame is smaller than the longitudinal length, the horizontal data and the vertical data may be interchanged.

Continue to refer to Figure 1.

S140. Determine a target area in the Fibonacci spiral according to the main feature, and prompt the target area in the finder frame.

Wherein, the Fibonacci spiral comprises a spiral curve and a plurality of rectangles distributed along the spiral curve. The target area can be a point on the Fibonacci spiral or a rectangle on the Fibonacci spiral. The electronic device determines a target area in the Fibonacci spiral according to the main feature. For example, the determined target area is a rectangle in the Fibonacci spiral, as shown in FIG.

After the electronic device determines the target area in the Fibonacci spiral, the target area is prompted in the finder frame. After prompting the target area, the user can move the lens to quickly place the main feature in the target area. Thereby, the user can quickly obtain the best photographing effect.

It should be noted that the Fibonacci spiral created in the framing frame is only calculated by the electronic device and is invisible to the user. There are several ways to prompt the target area.

For example, as shown in FIG. 13, the target area can be displayed in the finder frame. The display may be performed by highlighting the edge of the target area, by blinking the target area, or by other means such as gradation. The manner in which the target area is prompted includes, but is not limited to, the manner enumerated above.

In some embodiments, as shown in FIG. 14, while the target area is presented, a text prompt may also be displayed in the finder frame to enhance the prompting effect. For example, the text prompt can be information such as "put the main feature in the prompt box".

After the user places the main feature in the target area, the photographing effect is as shown in FIG. Thus, the user can quickly achieve the best photo effect.

In some embodiments, as shown in FIG. 3, determining a target area in the Fibonacci spiral according to the main feature, and prompting the target area in the finder frame, includes the following steps:

S141, obtaining an area of the main feature and an area of each rectangle in the Fibonacci spiral;

S142, respectively, adapting an area of the main feature to an area of each rectangle in the Fibonacci spiral to obtain an adaptation result;

S143. Determine a target area in the Fibonacci spiral according to the adaptation result, and prompt the target area in the finder frame.

Wherein, the electronic device can calculate the area of the main feature according to the extracted main features. At the same time, the electronic device can calculate the area of each rectangle in the Fibonacci spiral. Subsequently, the area of the main feature is adapted to the area of each rectangle to determine the rectangle with the highest degree of area fit to the main feature.

Subsequently, the electronic device can determine the target area in the Fibonacci spiral according to the adaptation result, and prompt the target area in the finder frame.

In some embodiments, as shown in FIG. 4, the area of the main feature is respectively adapted to the area of each rectangle in the Fibonacci spiral to obtain an adaptation result, including the following steps:

S1421, respectively calculating an absolute value of a difference between an area of the main feature and an area of each of the rectangles;

S1422: determining a minimum absolute value from the plurality of calculated absolute values;

Determining the target area in the Fibonacci spiral according to the adaptation result, and prompting the target area in the finder frame, including:

S1431: Determine a rectangle corresponding to the smallest absolute value as a target area, and prompt the target area in the finder frame.

Wherein, the electronic device can separately calculate the absolute value of the difference between the area S0 of the main feature and the area Sn of each rectangle in the Fibonacci spiral (n is the number of the rectangle when the rectangular area is arranged from small to large)|S0- Sn|, and the rectangle corresponding to the smallest absolute value is determined as the target area.

For example, the area of the main feature S0=5 (where the unit of the area may be cm2), the area of the first rectangle S1=1, the area of the second rectangle S2=2, and the area of the third rectangle S3=6, The area of the fourth rectangle S4=15, then |S0-S1|=4, |S0-S2|=3, |S0-S3|=1, |S0-S4|=10. At this time, the value of |S0-S3| is the smallest, and the third rectangle can be determined as the target area. Then, the target area is prompted in the finder frame.

In the specific implementation, the present invention is not limited by the order of execution of the various steps described. In the case where no conflict occurs, some steps may be performed in other orders or simultaneously.

It can be seen that the photographing composition method provided by the embodiment of the present invention acquires image information in the framing frame; analyzes the image information to extract main features in the image information; and establishes a Fibonacci spiral in the framing frame. a line; determining a target area in the Fibonacci spiral according to the main feature, and prompting the target area in the finder frame. The scheme establishes a Fibonacci spiral in the framing frame, determines the target area in the Fibonacci spiral by the main features in the image information, and prompts the target area to remind the user to place the main feature in the target area.

The embodiment of the present invention further provides a photo composition device, which can be integrated into an electronic device, and the electronic device can be an electronic device such as a digital camera or a smart phone.

As shown in FIG. 16 , the photo composition device 200 includes an acquisition module 201 , an analysis module 202 , an establishment module 203 , and a determination module 204 .

The obtaining module 201 is configured to acquire image information in the finder frame.

Among them, the photo composition device can be integrated in electronic devices such as digital cameras and smart phones. The electronic device has a camera and a framing frame. The camera is used to capture image information in the external environment. The image information captured by the camera can be displayed in the viewfinder. When the smartphone implements the camera function, the image information collected by the camera can be displayed on the display screen. At this point, the display of the smartphone acts as a framing frame.

During the photographing process, the acquiring module 201 in the photographing composition device can acquire the image information displayed in the finder frame, and analyze and process the image information.

In an actual application, the obtaining module 201 may acquire image information of the framing frame once every interval. For example, image information can be acquired once per second.

The analyzing module 202 is configured to analyze the image information to extract a main feature in the image information.

After the obtaining module 201 obtains the image information in the framing frame, the analyzing module 202 analyzes the image information to extract the main features in the image information. Image information typically includes a main feature and a background. Among them, the main feature is the feature that the user wants to highlight during the photographing process, such as characters, buildings, animals, and the like. The background is the environmental information around the main feature.

In the embodiment of the present invention, the training module 205 may apply the convolutional neural network to train the image information analysis model, and store the image information analysis model in the electronic device. The image information analysis model is used to analyze and identify images. After the obtaining module 201 obtains the image information, the analyzing module 202 calls the image information analysis model stored in the electronic device to analyze the image information to extract the main features in the image information.

A module 203 is created for establishing a Fibonacci spiral in the framing frame.

After the analysis module 202 extracts the main features in the image information, the building module 203 can establish a Fibonacci spiral in the framing frame.

In some embodiments, as shown in FIG. 18, the photo composition device 200 further includes a determination module 206.

The determining module 206 is configured to determine whether the main feature extraction is successful;

The establishing module 203 is configured to establish a Fibonacci spiral in the finder frame when the determining module 206 determines YES.

The judging module 206 may compare the plurality of main features extracted within a period of time to determine the similarity between the plurality of main features in the period of time. When the similarity between each two adjacent main features is greater than the preset value, the main feature extraction is considered to be successful, otherwise the main feature extraction is considered unsuccessful. The preset value may be a preset value, for example, 70%. When the main feature extraction is successful, the building module 203 creates a Fibonacci spiral in the framing frame.

For example, when the analysis module 202 extracts the main feature once per second, the judging module 206 can compare the five main features extracted within 5 seconds to determine the similarity between the five main features. When the similarity between each two adjacent main features of the five main features is greater than 70%, the main feature extraction is considered to be successful.

In some embodiments, the determining module 206 is further configured to:

When the judging module 206 judges that the main feature extraction is unsuccessful, the user may be prompted to specify the main feature in the framing frame. For example, the text message "Please specify the main feature in the image information" can be displayed in the finder frame to prompt the user.

Subsequently, the judging module 206 receives the touch operation of the user on the finder frame, and determines an area corresponding to the touch operation in the image information as the main feature. The user's touch operation may be a click operation or a sliding operation. After determining the primary feature, the setup module 203 creates a Fibonacci spiral in the framing frame.

Among them, the horizontal reference line divides the framing frame into upper and lower parts, and the ratio of the lower part to the upper part is the golden ratio. The vertical reference line divides the framing frame into two parts, and the ratio of the left half to the right half is the golden ratio.

Subsequently, the second determining sub-module 2032 determines the intersection O of the lateral reference line and the longitudinal reference line as the origin, and the second establishing sub-module 2033 establishes a Fibonacci spiral in the finder frame starting from the origin.

In the process of establishing the Fibonacci spiral, you can first establish a Cartesian coordinate system with O as the origin, the horizontal reference line as the X axis, and the vertical reference line as the Y axis.

The ratio of the lower region to the upper region of the lateral reference line 1 is a golden ratio, and the ratio of the upper region to the lower region of the lateral reference line 2 is a golden ratio. The ratio of the left region to the right region of the longitudinal reference line 1 is a golden ratio, and the ratio of the right region to the left region of the longitudinal reference line 2 is a golden ratio. The two lateral reference lines and the two longitudinal reference lines form four intersections A, B, C, D.

The horizontal center line divides the framing frame into upper and lower halves. The vertical center line divides the framing frame into left and right halves. The horizontal center line and the vertical center line divide the framing frame into four areas: the lower left area, the upper left area, the upper right area, and the lower right area. Among them, the intersection point A is located in the lower left area, the intersection point B is located in the upper left area, the intersection point C is located in the upper right area, and the intersection point D is located in the lower right area.

When the main feature spans a plurality of regions, for example, the main feature spans the lower left region and the upper left region, the region in which most of the main feature is located is determined as the start region.

The determining module 204 is configured to determine a target area in the Fibonacci spiral according to the main feature, and prompt the target area in the finder frame.

Wherein, the Fibonacci spiral comprises a spiral curve and a plurality of rectangles distributed along the spiral curve. The target area can be a point on the Fibonacci spiral or a rectangle on the Fibonacci spiral. The determination module 204 determines a target area in the Fibonacci spiral according to the main feature and prompts the target area in the finder frame. After prompting the target area, the user can move the lens to quickly place the main feature in the target area. Thereby, the user can quickly obtain the best photographing effect.

For example, the target area can be displayed in the finder frame. The display may be performed by highlighting the edge of the target area, by blinking the target area, or by other means such as gradation. The manner in which the target area is prompted includes, but is not limited to, the manner enumerated above.
