Fig. 2 is a schematic flow chart of a method for displaying an edge image according to an embodiment of the present invention. The execution subject of the method may be a terminal device, as shown in fig. 2, the method 200 includes:

and S210, acquiring an edge image corresponding to a reference image included in the image displayed on the main screen.

According to different application scenes, images displayed on the main screen are different, for example, when the terminal equipment answers a call, the images displayed on the main screen are call interface images; when the terminal equipment plays music, the image displayed on the main screen is a music interface image. The application scene of the terminal equipment further comprises the steps of using a voice assistant, using voice to unlock, recording and alarm clock. The terminal device determines a reference pattern from the image displayed on the main screen, and the position or shape of the reference pattern is used to determine the position where the edge image is displayed on the side screen.

When the main screen displays the call interface image, the terminal device may determine that an incoming call image indicating an incoming call object is determined from the call interface image as a reference image, and for example, the incoming call image may include an avatar of the incoming call object or may include a name of the incoming call object. When the main screen displays the music interface image, the terminal device may determine the singer avatar as a reference image from the music interface image, or may determine the album image as a reference image from the music interface image.

And S220, determining the display position of the edge image on the side screen according to the position or the shape of the reference image.

After the terminal device determines the reference image, the position of the edge image can be determined according to the position or the shape of the reference image. Fig. 3A and 3B are schematic diagrams respectively showing a method of determining the position of an edge image from the position of a reference image.

As shown in fig. 3A, the reference image includes an incoming call image for indicating a contact corresponding to an incoming call and an irregular curve outside the incoming call image, the center portion of the incoming call image is a head portrait of the contact, the edge image is an elliptical image, and the position of the elliptical image is determined according to the position of the incoming call image, for example, a coordinate system is established with the left frame of the terminal device shown in fig. 3A as a Y-axis and the upper frame as an X-axis, and then the Y-coordinate value of the center of the elliptical image (i.e., the intersection of the major axis and the minor axis of the ellipse) may be equal to the Y-coordinate value of the center of the incoming call image (i.e., the center of the circular head portrait. The Y coordinate value of the center of the elliptical image may be different from the Y coordinate value of the center of the incoming call image, wherein the Y coordinate value of the center of the left elliptical image may be the same as or different from the Y coordinate value of the right elliptical image.

As shown in fig. 3B, the reference image includes an alarm clock image, the alarm clock image includes a circular remaining time image and an irregular curve around the remaining time image, the edge image is an elliptical image, and the position of the elliptical image is determined according to the position of the alarm clock image, for example, a coordinate system is established by taking the left frame of the terminal device shown in fig. 3B as the Y axis and the upper frame as the X axis, so that the Y coordinate value of the center of the elliptical image (i.e., the intersection point of the major axis and the minor axis of the ellipse) may be smaller than the Y coordinate value of the center of the alarm clock image (i.e., the center of the circular head), wherein the Y coordinate value of the center of the left elliptical image may be the same as or different from the.

It should be noted that, in the above embodiment, the reference image displays the line of the circular image, the reference image may not display the line of the circular image, and the method for determining the display position of the edge image according to the position of the reference image is only an example, and the embodiment of the present invention is not limited thereto.

The terminal device may also determine the display position of the edge image according to the shape of the reference image, for example, when the reference image is a circular image, the terminal device may determine that the position at which the edge image is displayed is located on the same horizontal plane as the reference image (in which the terminal device is vertically placed); when the reference image is an irregular image, a reference point may be determined from the reference image, and the display position of the edge image may be determined based on the position of the reference point.

And S230, displaying the edge image at the display position of the side screen.

The shape or position of the reference image may change with time, and the terminal device determines the display position of the edge image at the present time based on the shape or position of the reference image at the present time.

Therefore, the terminal device determines the display position of the edge image according to the reference image displayed on the main screen at the current moment, and determines the display position of the edge image on the side screen according to the position or the shape of the reference image by determining the reference image from the image displayed on the main screen, so that the position of the edge image and the shape or the position of the image displayed on the main screen can be dynamically combined, the visual experience of the terminal device is enhanced, and the satisfaction degree of user experience is improved.

Optionally, the determining a display position of an edge image on the side screen according to the shape of the reference image includes:

s221, determining reference pixel points of the reference image according to the shape of the reference image, wherein the reference pixel points are pixel points on the edge of the reference image, which are farthest from the center of the reference image

S222, determining the display position of the edge image on the side screen according to the position of the reference pixel point, wherein the reference point is the point on the edge of the reference image, which is farthest from the center of the reference image.

For convenience of understanding the embodiments of the present invention, the following describes the embodiments of the present invention by taking an incoming call scene as an example, but the method for displaying an edge image provided by the present invention is not limited thereto.

The reference image may be obtained by fusing a large circle with a radius R and three small circles with a radius R through a Metaball algorithm, and obtaining the above-mentioned incoming image through the Metaball algorithm may be implemented by the prior art, and is not described herein again.

As shown in fig. 4, it is possible to arrange that the centers of three small circles are distributed on the circumference of a large circle in an equilateral triangle manner, and to use this state as the initial state of the reference image. The centers of the three small circles can move on the radius of the large circle. For a clearer description of the reference image, fig. 4 shows the outer contour of three small circles and the shape of an equilateral triangle, and in fact, the reference image seen by the user is a polygonal image including bumps.

The large circle and the small circle are fused by Metaball algorithm to form a new visual image, as shown in FIG. 5, the fused image is an irregular image with a plurality of bulges on the edge, and the size and the position of the bulges can be controlled by controlling the position relation of the small circle and the large circle. When the small circle is inscribed in the large circle, the distance between the reference pixel point (i.e., the point of the protrusion having the largest distance from the center of the large circle, hereinafter referred to as "reference point") and the center of the large circle is the smallest, the smallest distance is R, and the shape of the fused reference image is shown as "minimum protrusion state" in fig. 5; when the center of the small circle is located on the circumference of the large circle, the distance between the reference point and the center of the large circle is the largest, the largest distance is R + R, and the shape of the fused reference image is shown as the "maximum convex state" in fig. 5. In the process of ringing an incoming call, the reference image may be static or may move, and the movement mode of the reference image may be, for example, that the incoming call image is static, the protrusions of the edge continuously rotate, and each protrusion of the reference image continuously changes between the maximum protrusion state and the minimum protrusion state.

The center of the great circle is the center of the fused reference image, the symmetric center is the center of the reference image for the centrosymmetric reference image, and the center of the reference image for the non-centrosymmetric reference image can be determined by the method in the prior art, which is not described herein again.

The above embodiments are merely examples, and the embodiments of the present invention are not limited thereto, and the number of small circles may also be other numbers, the reference image may also be obtained by fixing one small circle and moving the center of the large circle on the radius of the small circle, and the reference image may also be other images.

To describe the method for determining the display position of the edge image according to the reference point, we set up a coordinate system as shown in fig. 6, where the origin of coordinates (0, 0) is located at the upper left corner of the main screen, the edge image may be an elliptical image, and the Y-coordinate value of the center of the elliptical image (i.e., the intersection of the major axis and the minor axis of the ellipse) may be set to be the same as the Y-coordinate value of the reference point, or may be set to be greater than or less than the Y-coordinate value of the reference point.

As an alternative embodiment, the terminal device may determine the initial position of the elliptical image from the position of the reference image, and thereafter determine the position of the elliptical image from the position of the reference point of the reference image, the position of the elliptical image varying with the movement of the reference point. The size of the elliptical image is related to the size of the reference image, when the size of the reference image is larger, the size of the elliptical image is larger, when the size of the reference image is smaller, the size of the elliptical image is smaller, the maximum size of the elliptical image can be set to be 2 times of the initial size, in the embodiment of the invention, the change of the size of the elliptical image refers to the change of the length of the short axis of the elliptical image, and the length of the long axis of the elliptical image can be preset to be 20px (pixels). When the reference image size is large, the initial size of the elliptical image may be set to be large, and when the reference image size is small, the initial size of the elliptical image may be set to be small.

Alternatively, the elliptical image may be generated by processing the reference image in a preset method.

As shown in fig. 7, the reference image has a width a and a length b at the current time, and the width and the length of the reference image may vary with the change of the sound property of the audio.

The reference image is deformed according to a certain proportion. For example, the width of the reference image is set to a₁0.5a, length set as b₁The image shown in fig. 8 was obtained as 1.5 b.

The image shown in fig. 8 is divided, for example, by cutting the left half of the image shown in fig. 8, as indicated by a broken line in fig. 8, which is a vertical line passing through the highest point of the image shown in fig. 8, and the image obtained after the division processing is shown in fig. 9.

The image shown in fig. 9 is mapped into an ellipse by a preset algorithm or software, for example, the image shown in fig. 9 can be processed by a plug-in bucket to obtain an ellipse a shown in fig. 10, and the width of the ellipse a is a₂Length of b₂。

Performing preset deformation processing on the ellipse A to obtain display on the side screenThe ellipse a may be optionally transversely compressed to 10% and longitudinally elongated to 135% to obtain an elliptical image displayed on the side screen, that is, the initial size of the elliptical image displayed on the side screen is the width a₃＝10％a₂Length b₃＝135％b₂. The resulting elliptical image displayed on the side screen is shown in fig. 11.

For example, the center point of the elliptical image is consistent with the Y coordinate of the point (i.e., the reference point) on the edge of the reference image farthest from the center point of the reference image, and the position of the elliptical image changes with the change of the position of the reference point in visual effect, the method for calculating the Y coordinate of the reference point is shown in fig. 6, and for convenience of description, a schematic diagram of the reference image before fusion is used for description, in fig. 6, the point P indicates the point on the edge of the reference image farthest from the center point of the reference image, the coordinate of the point P is (X, Y), θ indicates the included angle between the point P and the X axis, and the coordinate position of the point P is:

X＝(R+r)*cosθ，Y＝(R+r)*sinθ。

fig. 12A and 12B show a process in which the position of the elliptical image changes with the rotation of the reference image. The dynamic ellipse 1 indicates the position of the elliptical image at the first time, the Y-coordinate value of the reference point changes with the rotation of the reference image, and the dynamic ellipse 2 indicates the position of the elliptical image at the second time. The reference image may be rotated according to the playing of the audio data, and when the audio data stops playing (for example, when the call is over or the user clicks a pause button), all the data parsed by the terminal device are 0, the elliptical image is no longer displayed on the side screen or the elliptical image with a still position is displayed on the side screen.

The above embodiments are merely examples, and the embodiments of the present invention are not limited thereto. The embodiment of the invention can also be applied to a music playing scene, a recording scene, an alarm clock scene, a scene using a voice assistant or other possible application scenes, correspondingly, different reference images and edge images can be determined according to different application scenes, and the positions of the edge images can be determined according to the shapes or the positions of the reference images.

According to the method for displaying the edge image, provided by the embodiment of the invention, the display position of the edge image on the side screen is determined according to the position or the shape of the reference image, so that the visual dynamic effect and the three-dimensional feeling are added for a user, and the satisfaction degree of user experience is improved.

In addition to determining the position of the edge image from the position or shape of the reference image, the electronic device may determine the shape of the edge image from the sound properties of the played audio.

Fig. 13 is a schematic flow chart of another method for displaying an edge image according to an embodiment of the present invention. The execution subject of the method may be a terminal device, as shown in fig. 13, and the method 300 includes:

s310, acquiring attribute information and an attribute information threshold of sound represented by audio data, wherein the audio data is data obtained by microphone recording, or the audio data is data used for earphone or loudspeaker playing.

And S330, displaying the edge image at the display position of the side screen.

The attribute information of the sound includes phase information, frequency information, period information, amplitude information, and the like, and the method for displaying the edge image according to the embodiment of the present invention will be described below by taking the phase information as an example.

Depending on the sampling frequency (e.g., 10000mHz), a different amount of frequency information can be obtained, as shown in fig. 14, where the abscissa represents the frequency and the ordinate represents the phase spectrum value obtained by computing the frequency domain data using fourier transform, the phase spectrum value can be, for example, a value represented by 8 bits, and the range is (-128, 128), and there are N total phase spectrum values, corresponding to N frequency values, respectively.

The method of determining the shape of the edge image from the attribute information is as follows:

summing phase spectrum values over a period of time (e.g., 1ms), e.g., the phase spectrum shown in fig. 14 corresponds to 1ms, adding the N phase spectrum values shown in fig. 14 to obtain a SUM of phase spectrum values (i.e., values of attribute information of a sound represented by audio data), and SUM₁Represents, SUM₁Comparing with attribute information threshold if SUM₁Smaller than the attribute information threshold, the SUM is determined₁Invalidation, keeping the shape of the edge image unchanged; if SUM₁If the attribute information is greater than or equal to the attribute information threshold, the SUM is determined₁Is a valid sound attribute value, and the edge image is processed according to the following procedure. The attribute information threshold may be preset or may be obtained by other methods, for example, by adding the sum of the phase spectrum values of the x-th to y-th periods (assuming that the sum of the phase spectrum values of the m-th to n-th periods are all valid sound attribute values, there are m-n +1 phase spectrum values in total) and dividing by m-n +1 to obtain an average value, which may be used as the attribute information threshold, wherein the m-th to n-th periods are all located before the period of time.

After the effective sound attribute value is obtained, the display size of the edge image can be determined according to the relation between the preset sound attribute value and the display size of the edge image, so that the edge image is determined, or the edge image can be determined according to other methods in the prior art, and the edge image is displayed at the display position of the side screen.

Optionally, the determining a display size of the edge image according to the value of the attribute information, so as to determine the edge image, includes:

s321, determining the change rate of the size of the edge image according to the value of the attribute information, a preset maximum threshold and a preset minimum threshold;

s322, determining the display size of the edge image according to the change rate and the initial size of the edge image.

Obtaining valid sound attribute values (i.e., SUM)₁) And then, determining the change rate of the size of the edge image according to the effective sound attribute value, a preset maximum threshold value and a preset minimum threshold value. The maximum threshold may be denoted as basmax, and the minimum threshold may be denoted as basmin, where basmax and basmin are values obtained according to statistical analysis of a large number of different types of sound files, and may be according to formula k₁＝(SUM₁-bassMin)/(bassMax-bassMin) yields a rate of change k₁. The above formula is merely exemplary, and k can be obtained by other formulas₁。

Then according to k₁The initial size of the edge image determines the display size of the edge image. For example, the formula d₁＝(k₁+1) p yields the display size d of the edge image₁Where p is an initial size of the edge image, a size of the edge image before the first period corresponding to a period adjacent to the first period may also be referred to as an initial size, and when the edge image is an elliptical image, the display size may indicate a length of a short axis of the elliptical image. The above formula is merely illustrative, and d can be obtained by other formulas₁。

Optionally, the attribute information is an amplitude (i.e., amplitude) or a phase of a frequency component of the sound.

Optionally, the edge image includes a first edge image and a second edge image, the size of the first edge image is obtained according to the amplitude or the phase of the first frequency component of the sound, the size of the second edge image is obtained according to the amplitude or the phase of the second frequency component of the sound, and the frequency band of the first frequency component is different from the frequency band of the second frequency component.

In the embodiment of the present invention, the frequency band of the first frequency component of the sound is different from the frequency band of the second frequency component of the sound, for example, according to the difference of the sound frequencies, the sound in different frequency ranges may be divided into a bass (20Hz to 250Hz), a midrange (250Hz to 4kHz) and a treble (4kHz to 20kHz), phase spectrum values of the low, middle and high frequency sounds are respectively counted, and the phase spectrum value of the first frequency component may be a phase spectrum value corresponding to the bass.

In the embodiment of the present invention, the curved screen includes a first side screen and a second side screen, and the first side screen and the second side screen may be, for example, side screens located on the left and right sides of the terminal device (where the main screen faces the user). After determining the display size of the first edge image and the display size of the second edge image, the terminal device displays the first edge image and the second edge image on the two side screens, respectively. As another example, the left side screen may display a real-time edge image, and the right side screen may display an edge image delayed by a period of time (e.g., 800 ms).

Therefore, the method for displaying the edge image in the embodiment of the invention enhances the perception of the user on the attribute information of the audio data, enhances the interaction between the user and the terminal and improves the satisfaction degree of the user experience by displaying the edge image corresponding to different sound attribute values on the side screens at different positions.

Optionally, the method 300 further comprises:

s340, updating the attribute information threshold according to the value of the sound attribute.

For example, the time range of the first time interval may be determined to be 1-100 ms, the phase spectrum values of each sub-time interval (e.g. 1ms) in the first time interval are summed, and the result obtained by the summation is denoted as SUM_i(i is 1 ~ 100), i.e., the SUM of the phase spectrum values in the 1ms is SUM₁The SUM of the phase spectrum values in the 2ms is SUM₂And so on. Assuming that the SUM of 100 phase spectrum values in the first time interval is a valid sound attribute value, adding the SUM of 100 phase spectrum values and dividing by 100 to obtain a result, which is denoted as SUM, the SUM can be used as an attribute information threshold in the second time interval, assuming that the time range of the second time interval is 101 ms-200 ms, the SUM of the phase spectrum values of the audio data in the 101ms is obtained to obtain SUM₁₀₁If SUM₁₀₁If it is less than SUM, determining SUM₁₀₁If the attribute value is not the valid sound attribute value, the next operation is not executed on the edge image; if SUM₁₀₁If it is greater than SUM, determining SUM₁₀₁Is a valid sound attribute value, and determines the display size of the 101 ms-th edge image. If the program is run for the first time, a value set in advance may be used as the attribute information threshold.

Therefore, the method for displaying the edge image, provided by the embodiment of the invention, determines the attribute information threshold of the current time interval according to the effective sound attribute value of the last time interval, so that the attribute information threshold can be optimized in real time, the size change of the edge image is softer, and the satisfaction degree of user experience is improved.

According to the method for displaying the edge image, whether the value indicated by the attribute information of the sound within a period of time is the effective sound attribute value is determined through the attribute information threshold, and the change rate of the size of the edge image is obtained by processing the effective sound attribute value through the preset maximum threshold and the preset minimum threshold, so that the influence of calculation errors or background noise on the sound attribute value can be reduced, the drastic change of the size of the edge image is avoided, and the satisfaction degree of user experience is improved.

s420, determining the color of the edge image according to the attribute of the reference image or the information of the external environment, so as to determine the edge image;

and S430, displaying the edge image at the display position of the side screen.

According to different application scenes, images displayed on the main screen are different, for example, when the terminal equipment answers a call, the images displayed on the main screen are call interface images; when the terminal equipment plays music, the image displayed on the main screen is a music interface image. The application scene of the terminal equipment further comprises the steps of using a voice assistant, using voice to unlock, recording and alarm clock. The terminal device needs to determine a reference pattern from the image displayed on the home screen.

The terminal device determines the color of the edge image according to the attribute of the reference image after determining the reference image, wherein the attribute of the reference image comprises color, content, transparency, shape and the like. For example, when the color of the reference image belongs to a cold color system color, the terminal device may select one from preset cold color system colors (e.g., blue, green) as the color of the edge image; when the content displayed by the reference image is a steam engine, one of preset dark colors (for example, dark yellow and black white) can be selected as the color of the edge image; when the transparency of the reference image is high, the terminal device may select one from a preset light color system (e.g., white, light yellow) as the edge image; when the reference image is a circular image, the terminal device may select rainbow color as the color of the edge image.

The terminal device can also determine the color of the edge image according to the external environment, such as the weather condition, the temperature and other conditions. For example: when the temperature is higher than the preset temperature, the color of the graph can be set to be warm; when the temperature is low relative to the preset temperature, the color of the graphic may be set to a cool color.

Therefore, according to the method for displaying the edge image provided by the embodiment of the invention, the color of the edge image is determined according to the attribute of the reference image displayed on the main screen or the information of the external environment where the current electronic equipment is located, so that the visual experience of the electronic equipment is enhanced, and the satisfaction degree of user experience is improved.

As an alternative embodiment, the color of the edge image may be a pure color or a gradient color, and the edge image may also have a certain transparency. A pure color is a single color and a color without gray, for example, when the attribute of a pixel is represented by HSB (hue, saturation, brightness), a color with a saturation equal to 50% is called a pure color.

Taking the edge image as an elliptical image as an example, the color filling method of the elliptical image is as follows:

the intersection O (x) of the major axis and the minor axis of an elliptical image (hereinafter abbreviated as ellipse)₀，y₀) A rectangular coordinate system is established for the origin, and the length of the major axis of the ellipse is set to be 2a, and the length of the minor axis is set to be 2b, the ellipse can be expressed by the following formula,

(where C is a constant).

The value of a can be preset to be 20px, and the value range of b is [ R, R + R]. Point P (x)_p,y_p) The coordinate of the point P is substituted into the above-mentioned ellipse equation to calculate for any point in the plane where the ellipse is located, and the distance d from any point in the plane to the point O, that is,

by calculating d/C, it can be known that: the value of the center of the ellipse is 0, the value of the point on the edge of the ellipse is 1, the values from the center of the ellipse to the edge of the ellipse vary uniformly from 0 to 1, and the ratio outside the ellipse varies from 1 to 0.

The calculation formula for defining the transparency of any point in the plane of the ellipse is

Alpha＝1—d/C。

The transparency value of each point can be obtained by a transparency calculation formula, so that the transparency gradual change effect gradually changing from the center of the ellipse to the periphery is obtained.

The attribute of each point in the side screen display area is represented by (R, G, B, a), where the color attribute is represented by a preset RGB value of a pure color, and the transparency (a value, i.e., Alpha) of each point is represented by a transparency value calculated by the above formula, so that the effect of filling with the pure color can be obtained.

As another alternative embodiment, a gradient color fill edge image may be used, as shown in fig. 16, where startColor (start color) and endColor (end color) are two fill colors used for generating a gradient color, a color (color) point is a fill color at any point, a startColor is taken as a starting point, an endColor is taken as an end point, a percentage of the startColor at the starting point is 100%, a percentage of the endColor at the end point is 100%, and for any point between the starting point and the end point, a gradient fill effect of two colors can be obtained by adjusting a ratio of the startColor and the endColor, a color at any point can be represented by the following formula,

color＝startColor+(endColor-startColor)*ratio。

wherein, the ratio is the ratio value of any point endColor, and the range is 0 to 1.

By the method, the color value and the transparency value of any point of the edge image can be obtained
