For convenience of understanding, the following embodiments of the present application will take an electronic device having the structure shown in fig. 2 and fig. 3 as an example, and the picture display method provided in the embodiments of the present application will be described with reference to the scenario shown in fig. 1. As shown in fig. 4, the method for displaying a picture provided in the embodiment of the present application includes:

101, selecting a plurality of candidate pictures from the photographed pictures.

In this embodiment of the present application, the shot picture may be a picture shot and stored by the device, or may be a picture shot and transmitted to the device by other devices.

The candidate pictures can be selected from the photographed pictures according to any one or more factors of photographing time, photographing place, photographing object and aesthetic quality of the pictures. For example, a picture taken at the same shooting location on the same day may be selected as a candidate picture; or selecting the pictures shot by taking the same shooting object as a main body in one month as candidate pictures and the like. In this embodiment of the present application, the number of candidate pictures selected may be determined based on a preset value, or may be flexibly determined based on an actual screening result.

Further, in the embodiment of the present application, the electronic device may generate a new picture set according to a set period, and after the user starts the target application and triggers the display of the first page on the target application interface, the newly generated picture set is displayed on the first page. Meanwhile, the previously generated picture set may be displayed together with the newly generated picture set. The setting period may be flexibly set, and may be, for example, a period of a week, a period of a month, or the like.

Based on the implementation manner, in the embodiment of the application, the electronic device may detect the current time, and after detecting that the current time reaches the set period node, may trigger to select a candidate picture from the captured pictures, so as to generate a new picture set.

In other implementations, the device state may be detected first after detecting that the current time has reached the set period node. The device status may include, for example, battery state of charge, device operational status, screen display status, and the like. And triggering to select candidate pictures from the shot pictures under the condition that the electric quantity of the equipment is determined to be larger than a preset electric quantity threshold value, and/or the current running state of the equipment is good, the resource occupancy rate is lower than a set threshold value, and/or the equipment is in an off-screen charging state so as to generate a new picture set. And when the electric quantity of the equipment is determined to be smaller than a preset electric quantity threshold value, and/or the current resource occupancy rate of the equipment is higher than a set threshold value, and/or the equipment is in a bright screen state, the equipment state can be continuously detected until the equipment state reaches the above condition, and then the candidate picture is triggered to be selected from the shot pictures. Thus, it is possible to prevent the power consumption of the device from being increased in the case of low power, and to prevent the resource consumption from being further increased in the case of high resource occupancy, resulting in a reduction in the operation efficiency of other applications.

Or the electronic device can trigger to generate a new picture set according to the number of the newly added pictures in the target time period. Specifically, the electronic device may count the number of subsequent newly added pictures after generating the new picture set each time, and trigger to generate the new picture set when determining that the number of newly added pictures reaches the set threshold.

Alternatively, in another implementation, in the case that the number of newly added pictures is detected to reach the set threshold, similar to the previous implementation, the device state may be detected first, and in the case that it is determined that the device state meets the above condition, the selection of the candidate picture from the already taken pictures is triggered so as to generate a new picture set.

102, screening a plurality of target pictures from the plurality of candidate pictures according to the color characteristics of the plurality of candidate pictures.

After the candidate pictures are obtained, in the embodiment of the application, the candidate pictures can be further screened, so that a plurality of target pictures with consistent color tones are obtained.

First, a first index value between a plurality of candidate pictures may be calculated according to color characteristics of the plurality of candidate pictures.

In this embodiment of the present application, a chrominance distribution map corresponding to each candidate picture may be generated first, and then, based on the chrominance distribution map, a first index value between each candidate picture is calculated. The first index value may reflect a degree of similarity in chromaticity of each candidate picture.

The following describes a method for generating a chromaticity distribution map.

Specifically, each candidate picture may be first converted from RGB format to HSV format. Where H represents chromaticity, S represents saturation, and V represents luminance. Fig. 5 is a schematic view of a color wheel, as shown in fig. 5, the distribution range of chromaticity is 0 deg. to 360 deg., each degree corresponding to a particular chromaticity. Wherein 0 ° corresponds to red, 60 ° corresponds to yellow, 120 ° corresponds to green, 180 ° corresponds to cyan, 240 ° corresponds to blue, 300 ° corresponds to violet. Since a typical image is stored in 8 bits, the readable chromaticity range is 0-180, with each degree representing two degrees of actual distribution. Using functions

The distribution can be converted to 0-360.

Furthermore, based on the candidate pictures in the HSV format, after the images of the H channels are acquired, the chromaticity of each pixel in the H channels of the candidate pictures can be counted, and a chromaticity distribution diagram corresponding to each candidate picture can be generated. Fig. 6 is an exemplary representation of a chromaticity distribution map, as shown in fig. 6, where chromaticity coordinates may be generated at corresponding locations on the color wheel based on the distribution of the respective chromaticities in the candidate pictures. For any chromaticity, the more the distribution amount is, the higher the coordinate value of the corresponding position in the color wheel is.

Further, a method for calculating the first index value between each candidate picture is described below.

In the embodiment of the application, any one picture can be selected from the candidate pictures as the reference picture. Further, first index values between the remaining candidate pictures and the reference picture may be calculated based on the chromaticity distribution map, respectively. The first index value may include various types, such as centroid, correlation coefficient CORREL, barbitacharyya, earth Moving Distance (EMD), and JS divergence. The centroid can reflect the distribution centroid of the chromaticity of the candidate pictures, and the closer the centroids of the chromaticity of the two pictures are, the smaller the hue difference of the two pictures is. The correlation coefficient, the Babbitt distance, the soil carrying distance and the JS scattering degree can be used for representing the similarity between any two candidate pictures, and the higher the correlation coefficient is, the smaller the Babbitt distance is, the smaller the soil carrying distance is, and the smaller the JS scattering degree is, the higher the chromaticity similarity between the two candidate pictures is.

The calculation formula of each first index value may refer to the prior art, and is briefly described in the embodiments of the present application.

The correlation coefficient has a value of 0-1, the larger the value is, the more similar the chromaticity is represented, and the calculation formula is as follows:

the pasteurization distance is used to measure the similarity of two discrete or continuous probability distributions. For discrete probability distributions p and q in the same domain X, the pasteurization distance is defined as:

/>

the earth moving distance is used for representing the minimum value of the average moving distance required for moving the discrete data distribution P into the discrete data distribution Q, and the calculation formula is as follows:

The JS divergence can be used for representing the similarity between two probability distributions, the value is between 0 and 1, and the calculation formula is as follows:

table 1 below is a schematic of one possible result of the first index value between the candidate pictures. In the case where the selected candidate picture 03 is a reference picture, a first index value between each of the remaining candidate pictures and the candidate picture 03 may be obtained as shown in table 1.

TABLE 1

Then, a plurality of target pictures with consistent hues can be screened from a plurality of candidate pictures according to the first index value.

Specifically, the picture to be removed may be determined from each candidate picture according to the statistical characteristics of each first index value.

In one possible implementation, an average value of each first index value may be calculated. Further, at least one first index value with the largest difference from the average value in the first index values can be determined, and the candidate picture corresponding to the at least one first index value is determined as the picture to be removed.

For ease of understanding, still taking the above table 1 as an example, the average value of the first index values may be calculated as 0.7134 (correlation coefficient), 0.3296 (barbituric distance), 5.3447 (soil carrying distance), 0.1329 (JS divergence), and 71.83 (centroid), respectively. It may be determined that the difference between the first index value between the candidate picture 05 and the reference picture and the above average value is the largest, and thus, the candidate picture 05 may be determined as the picture to be rejected.

In another possible implementation manner, after calculating the average value of each first index value, the target distribution range of the first index value may be further determined based on the average value. For example, a range obtained by adding or subtracting the variance to or from the average value may be determined as the target distribution range, or a range obtained by adding or subtracting the standard deviation to or from the average value may be determined as the target distribution range. And finally, determining the candidate pictures with the corresponding first index values outside the respective ranges of the targets as pictures to be removed.

Further, in the actual execution scene, because of randomness of the selection result of the reference picture, the selected reference picture may be the picture with the largest hue difference, and at this time, each calculated first index value may be located in the target distribution range, and the picture to be removed cannot be determined by the method.

In view of the above, in the embodiment of the present application, when each calculated first index value is located within the target distribution range, the reference picture may be reselected, and the first index value between the new reference picture and the remaining candidate pictures may be recalculated. And further, determining the picture to be removed based on the new calculation result.

Alternatively, in the embodiment of the present application, each candidate picture may be sequentially selected as a reference picture, the first index value is calculated multiple times, and the picture to be removed is determined based on the calculation result of each time. Therefore, the candidate pictures with larger tone difference can be prevented from being missed in the screening process, and the reliability of the scheme is further improved.

And 103, generating a picture set based on the plurality of target pictures.

104, responding to the triggering operation of the first control in the target application interface, and displaying a first page.

And 105, displaying the picture set on the first page.

In the embodiment of the application, after the target pictures are obtained, a picture set can be generated based on each target picture, and after the user triggers the target application and enters the first page of the target application, the newly generated picture set is displayed in the first page.

And responding to the triggering operation of the user on the target application icon in the main interface of the electronic equipment, and displaying the target application interface. And a plurality of page controls can be displayed in the target application interface, each page control can be used for triggering and displaying different picture display pages, and each picture display page can be used for displaying the shot pictures in different forms.

And responding to the triggering operation of the user on the first control in each page control, displaying a first page, wherein the first page can display the newly generated picture set in the embodiment. Meanwhile, the history picture set can be displayed together.

Specifically, the manner of displaying each picture set may be that, on the one hand, the picture set identification information is generated according to factors such as a shooting object, shooting time, shooting place and the like of each picture included in the picture set. The picture set identification information may include, for example, a picture set name, a picture taking time, a place, and the like. Examples of the "figure 2022, 6 to 12 months," and "recall Beijing" are possible. On the other hand, any picture in the picture set can be selected as the cover. Furthermore, covers of the respective picture sets and corresponding picture set identification information can be displayed respectively.

As shown in fig. 1, for example, the target application interface 700 may include four page controls, namely, a photo control, an album control, a time control, and an authoring control. In response to a trigger operation of the moment control therein, a moment page may be displayed and the newly generated picture set and the history picture set are displayed therein.

Fig. 7 is a schematic view of a first page according to an embodiment of the present application. As shown in fig. 7, a newly generated picture set 801 may be displayed in the upper half of the first page 800, while the lower half of the first page 800 in turn displays various historical picture sets 802 that have been previously generated. At this time, the up-down scrolling of the page may also be implemented in response to the user's sliding operation on the first page 800, so as to display more history picture sets 802.

After displaying the picture sets, the electronic device may also display a second page in response to a trigger operation on any one of the picture sets. The second page may display a cover of the picture set, identification information, and each picture included in the picture set. The cover of the picture set can also comprise a play control, and each picture in the picture set can be sequentially played in a video mode in response to the triggering operation of the play control. The triggering operation on the play control can be clicking the play control or clicking any position of the photo album cover. Before each picture contained in the picture set is displayed in the second page, cutting and scaling treatment can be carried out on each picture according to layout arrangement requirements, and the cut and scaled pictures are arranged and displayed.

Fig. 8 is a schematic view of a second page according to an embodiment of the present application. As shown in fig. 8, the upper half area of the second page 900 may display a cover 901 of the photo album, and a play control 9011 may be displayed in the cover 901. In response to a trigger operation to the play control 9011, each picture included in the picture set can be played in video form. The lower half of the second page 900 may display the individual pictures 902 contained in the picture set. In response to a sliding operation of the second page 900 by the user, scrolling up and down of the page may be implemented to display more pictures of the picture set.

Through the technical scheme, the pictures can be filtered based on the color characteristics, so that the pictures contained in the same picture set have consistent color tones, the visual jumping sense of a user can be relieved, the ornamental value of the picture set is enhanced, and the user experience is improved.

Fig. 9 is another schematic flowchart of a picture display method provided in an embodiment of the present application. In another embodiment of the present application, the method for displaying a picture may include:

and 201, selecting a plurality of candidate pictures from the shot pictures.

202, respectively calculating second index values of the plurality of candidate pictures according to content characteristics of the plurality of candidate pictures.

203, determining the index type of the first index value according to the second index value.

In the embodiment of the present application, after the candidate pictures are selected, the complexity level of performing tone contrast on each candidate picture may be determined based on the image content of each candidate picture. Further, in the case of low complexity, the calculation of the at least one type of the first index value may be performed according to the color characteristics of the candidate pictures, and the target pictures with consistent color tone may be selected based on the at least one type of the first index value, so that the calculation amount may be reduced. For example, it is possible to calculate only the centroid of the chromaticity distribution of each candidate picture, and to screen out target pictures of consistent hue based on the chromaticity centroid.

Conversely, under the condition of higher complexity, the first index values of multiple types can be calculated according to the color characteristics of the candidate pictures, and the target pictures with consistent color tones can be screened based on the first index values of multiple types, so that the accuracy of tone comparison can be improved. For example, a plurality of first index values such as centroid, correlation coefficient, barbituric distance, soil carrying distance, JS divergence, etc. may be calculated simultaneously.

Specifically, for each candidate picture in RGB format, a hash algorithm may be used to calculate a hash value for each candidate picture. The hash algorithm may be a mean hash algorithm, a difference value hash algorithm, a perceptual hash algorithm, or the like. The hash value of a picture can be used as a "fingerprint" of the picture to uniquely identify the picture. By comparing the hash values, the similarity of the two pictures in content can be obtained. The closer the hash value is, the higher the similarity of the two pictures in the content is, and the lower the similarity is otherwise.

Based on this, in the embodiment of the present application, when the difference in hash value between each candidate picture is smaller than the set threshold, it may be considered that the content similarity of each picture is high. For example, it is possible to take pictures of the same subject from similar shooting angles. At this time, the complexity of tone matching the candidate pictures is relatively low, and then it may be determined to use at least one type of first index value for tone matching. In contrast, in the case where the difference in hash value between the respective candidate pictures is larger than the set threshold, the respective picture contents are considered to be low in similarity. For example, it may be a picture taken of a different photographic subject. At this time, the complexity of tone matching the candidate pictures may be high, and then it may be determined to use multiple types of first index values for tone matching.

204, calculating a first index value between the plurality of candidate pictures according to the color characteristics of the plurality of candidate pictures.

And 205, screening a plurality of target pictures from the plurality of candidate pictures according to the first index value.

A picture set is generated based on the plurality of target pictures 206.

207, in response to a triggering operation of the first control in the target application interface, displaying a first page.

208, displaying the picture set on the first page.

After determining the type of the first index value, each first index value between each candidate picture can be calculated according to the color characteristics of each candidate picture, and each target picture with consistent tone can be determined based on the first index value. Further, a picture set may be generated based on each target picture, and after detecting a triggering operation on the first control, a corresponding picture set may be displayed on the first page. For specific implementation, reference may be made to the foregoing embodiments, and details are not described herein.

Through the technical scheme, under the condition that the picture complexity is high, the tone difference of each candidate picture can be compared by using multiple types of similarity evaluation indexes, and under the condition that the picture complexity is low, the tone difference of each candidate picture can be compared by using fewer types of similarity evaluation indexes. Therefore, the operation resources can be saved, and the accuracy of the operation result is ensured.
