In this way, a common physical architecture (e.g., touch-sensitive surface) of the terminal can support various applications with user interfaces that are intuitive and transparent to the user.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

Referring to fig. 1, which is a flowchart illustrating an implementation of a photographing behavior analysis method according to an embodiment of the present invention, where the photographing behavior analysis method is applied to a mobile terminal, as shown in the figure, the photographing behavior analysis method may include the following steps:

step S101, when a camera is started to shoot, shooting parameters of the camera and/or information of shot images are obtained.

In this embodiment of the present invention, step S101 may refer to acquiring, after a camera in the mobile terminal is started, if a click operation on a shooting key in a shooting interface is detected, a shooting parameter of the camera and/or information of a shot image. The shooting key may refer to an icon for triggering a shooting instruction.

It should be noted that, the camera in the mobile terminal may automatically adjust the photographing parameters of the camera according to different photographing scenes. That is, for different shooting scenes, the shooting parameters of the camera may be different, so as to ensure that the effect of the pictures shot by the camera is ideal. The shooting scenes include but are not limited to portrait scenes, landscape scenes, night scene scenes, sports scenes and the like, and different shooting scenes can be divided according to the intensity of light. The photographing parameters include, but are not limited to, a sensitivity ISO value and a shutter time length. For example, in a dark shooting scene, the camera automatically sets a higher ISO value in order to obtain a better quality photograph. Therefore, when the shooting scenes are different, the shooting parameters of the camera acquired in step S101 may be different.

Wherein ISO is an abbreviation of International Organization for Standardization, and is an english abbreviation of International standard Organization, and the chinese name of the degree of sensitivity ISO of a film (film or image sensor) to light specified by the Organization can be understood as: sensitivity. The shutter duration refers to the time setting of controlling light rays entering the lens by the camera, the shorter the shutter duration is, the less the light rays enter the lens, and the longer the shutter duration is, the more the light rays enter the lens.

The brightness value of the photographed image may refer to an average brightness value of all pixel points in the photographed image, that is, the brightness values corresponding to all pixel points in the photographed image are obtained, the brightness values corresponding to all pixel points are accumulated, the accumulated value is divided by the number of the pixel points in the photographed image, and the obtained value may be set as the brightness value of the photographed image.

And step S102, analyzing the photographing behavior of the user according to the photographing parameters and/or the information of the photographed image to obtain an analysis result.

In the embodiment of the invention, the photographing behavior of the user can be analyzed according to the photographing parameters and the information of the photographed image, and whether the photographing behavior of the user can cause underexposure of the image photographed by the camera is analyzed. It should be noted that, when a mobile terminal is used for taking a picture, the problem of overexposure does not generally occur, so the problem of overexposure can be eliminated in the present invention.

As another embodiment, the photographing behavior of the user is analyzed according to the information of the photographed image, and whether the photographing behavior of the user causes the image photographed by the camera to be out of focus is analyzed. When the shot image contains the face image, whether the composition of the face image is an ideal composition or not, namely whether the shooting action of the user can cause the image shot by the camera to deviate from the visual focus or not. The visual focus refers to a region which is considered by a user to attract own eyeballs and is quickly captured in a limited sight range.

The commonly used composition methods for taking pictures by a camera include a symmetrical composition and a golden section composition. The symmetrical composition is usually to place the object to be shot (i.e. the object to be shot) in the center of the picture, has the characteristics of balance, stability and correspondence, and is often used for representing symmetrical objects, buildings, objects with special styles and the like. The basic theory of golden section composition is derived from the golden section ratio of 1:0.618 or 1.618:1, and the golden section ratio is introduced into the photography process, so that the photographed image (i.e. the photo) can feel natural and comfortable, and is more attractive to the viewer. For example, the famous paintings "Mona Lisa", "last dinner" and "birth of Venus" all conform to the ratio of the golden section. The most common golden section patterns include the golden spiral and the golden squared figure. The golden spiral is a square formed by taking each number of a Fibonacci sequence as a length, and a series of diagonal points on the square form a path, so that a viewer can enjoy pictures in the framework in the most natural way. The golden nine-square grid is formed by making four lines on the upper, lower, left and right sides of a picture by golden section, and four points where the four lines of the nine-square grid meet are the most sensitive positions of the vision of people.

As another embodiment, the photographing behavior of the user is analyzed according to the photographing parameters, and whether the user has a hand trembling behavior during photographing is analyzed.

Step S103, generating a photographing report according to the analysis result, wherein the photographing report comprises the analysis result and a photographing suggestion corresponding to the analysis result.

In the embodiment of the invention, a photographing behavior analysis option can be set in a photographing interface of the mobile terminal, a user can start the photographing behavior analysis function by selecting whether the photographing behavior analysis function needs to be started or not, when the user selects 'yes', the photographing behavior analysis function can be started, an analysis result of the photographing behavior of the user in a preset time is recorded from the current moment, and the analysis result and a photographing suggestion corresponding to the analysis result are stored in the photographing report. When the duration of the mobile terminal analyzing the photographing behavior of the user reaches the preset time, obtaining an analysis result of the photographing behavior of the user within the preset time, generating a photographing report, sending the photographing report to the user in the form of a short message, a popup window or a label, or displaying the photographing report on a current interface of the mobile terminal when the clicking operation of the user on the photographing report in the photographing interface is detected.

The preset time may refer to a time length for analyzing the photographing behavior of the user, for example, one month, that is, the photographing behavior of the user in one month is analyzed. The analysis results include, but are not limited to, overexposure, out-of-focus of the captured image, and the occurrence of hand trembling behavior by the user while taking a picture. Optionally, in order to facilitate the user to know whether the photographing level of the user is improved, the photographing report may be generated at preset intervals, for example, the photographing behavior of the user is analyzed every month, and the photographing report is generated according to the analysis result.

In the embodiment of the present invention, before step S101, a corresponding relationship between the analysis result and the shooting suggestion may be preset, and different analysis results correspond to different shooting suggestions. For example, the shooting suggestion corresponding to the overexposure of the image can be set to be supplemented with ambient light during shooting; the shooting suggestion corresponding to the out-of-focus image can be set to be focused during shooting; the shooting suggestions corresponding to the deviation of the visual focus can be set to control the position of the face during shooting; the suggestion of shooing that the user took place hand tremble when shooing for the correspondence can set up to take hand tremble compensation measure when shooing, for example, uses the tripod or carries out the scene light filling when shooing to improve shutter speed, avoid the hand to tremble the action.

Optionally, the photographing parameter includes a sensitivity ISO value; the information of the photographed image includes a brightness value of the photographed image;

the analyzing the photographing behavior of the user according to the photographing parameters and the information of the photographed image comprises:

if the ISO value is larger than a preset sensitivity threshold and the brightness value of the shot image is smaller than a preset brightness threshold, determining that the analysis result is that the shot image is underexposed;

the generating of the photographed report according to the analysis result comprises:

and if the number of times of the image underexposure in the preset time is greater than a first preset threshold value, storing the image underexposure and a shooting suggestion corresponding to the image underexposure and adopting ambient light for light supplement during shooting in the shooting report.

In the embodiment of the invention, when the camera of the mobile terminal is used for photographing, the photographed image is generally not overexposed, so that when the ISO value of the photographed image is less than or equal to the preset sensitivity threshold and/or the brightness value of the photographed image is greater than or equal to the preset brightness threshold, the exposure of the image photographed by the camera is normal, a corresponding photographing suggestion does not need to be provided for a user, and the user can still photograph according to the photographing habit of the user during subsequent photographing.

Optionally, the information of the captured image includes a color contrast of an adjacent pixel point at a preset position in the captured image;

the analyzing the photographing behavior of the user according to the information of the photographed picture comprises:

if the color contrast is smaller than a preset contrast threshold, determining that the analysis result is that the shot image is out of focus;

and if the number of times of image defocusing in the preset time is greater than a second preset threshold value, storing the image defocusing and a photographing suggestion corresponding to the image defocusing and focusing during photographing in the photographing report.

In the embodiment of the present invention, when the number of the preset positions is one, the color contrast of the adjacent pixel point at the one preset position is the color contrast of the adjacent pixel point at the preset position in the photographed image; when the number of the preset positions is multiple, the average value of the color contrast of the adjacent pixel points at the multiple preset positions is the color contrast of the adjacent pixel points at the preset positions in the shot image. For example, if the number of the preset positions is three, and the color contrast of the adjacent pixel points at the three preset positions is A, B and C, respectively, the color contrast of the adjacent pixel points at the preset positions in the captured image is A, B

If the color contrast of the adjacent pixel points at the preset position in the shot image is greater than or equal to the preset contrast threshold, the shot image can be considered to be focused accurately.

The acquiring information of the photographed image includes:

detecting whether a face image exists in the shot image;

and if so, acquiring the position composition of the face image.

In the embodiment of the invention, the mobile terminal can detect whether a face image exists in an image shot by the camera through a face recognition technology, when the face image exists in the shot image, the position composition of the face image in the shot image is obtained, and when the face image does not exist in the shot image, the judging process of whether the face image deviates from the visual focus is finished.

The analyzing the photographing behavior of the user according to the information of the photographed image comprises:

if the position composition of the face image is not matched with the preset position composition, determining that the analysis result is that the face image deviates from a visual focus;

if the frequency of the human face image deviating from the visual focus within the preset time is greater than a third preset threshold value, the deviation of the visual focus and a shooting suggestion corresponding to the deviation of the visual focus and controlling the position of the human face during shooting are stored in the shooting report.

In the embodiment of the present invention, the preset position pattern includes, but is not limited to, a symmetric pattern, a golden section pattern, and the like. And if the position composition of the face image is matched with the preset position composition, determining that the face image does not deviate from the visual focus, providing corresponding photographing suggestions for the user is not needed, and the user can still photograph according to the photographing habit of the user when photographing the face image subsequently.

Optionally, the photographing parameter includes a shutter duration; the analyzing the photographing behavior of the user according to the photographing parameters comprises:

if the shutter duration is greater than the preset shutter duration, determining that the analysis result is that a user shakes hands when taking a picture;

and if the number of times of the hand shaking behavior of the user during photographing is greater than a fourth preset threshold value within the preset time, storing the photographing suggestion that the hand shaking behavior of the user during photographing and the hand shaking behavior correspond to adopt hand shaking compensation during photographing in the photographing report.

In the embodiment of the invention, the more times of the hand shaking behavior of the user during photographing in the preset time indicates that the greater the probability of the hand shaking behavior of the user during photographing; the smaller the times of the hand shaking behavior of the user during photographing in the preset time is, the smaller the probability that the hand shaking behavior of the user occurs during photographing is. If the number of times of the hand shaking behavior of the user during photographing is smaller than or equal to a fourth preset threshold value within the preset time, the probability that the hand shaking behavior of the user occurs during photographing is considered to be small and can be ignored, that is, a corresponding photographing suggestion for avoiding hand shaking is not required to be provided for the user.

It should be noted that, the mobile terminal may detect that the camera is started every time within a preset time, and when taking a picture, may obtain a shooting parameter of the camera and information of the shot image at the same time, determine whether the shot image is underexposed according to the shooting parameter of the camera and the information of the shot image, determine whether the shot image is out of focus according to the information of the shot image, determine whether the face image deviates from a visual focus when the shot image includes the face image, and determine whether a hand shaking behavior occurs when the user takes a picture according to the shooting parameter of the camera. Namely, the user's photographing behavior can be analyzed in the four situations at the same time when the photographing is started.

Because the four analysis results, such as underexposure of an image, defocusing of the image, deviation of a face image from a visual focus, shaking behavior and the like, may exist accidentally within the preset time, in order to more accurately judge whether the four analysis results appear when the user takes a picture, a corresponding shooting suggestion may be provided to the user only when the number of times of occurrence of each of the four analysis results within the preset time reaches a corresponding preset threshold. Since the photographing performance of each mobile terminal may be different, when setting a preset threshold corresponding to the number of times of occurrence of each analysis result (for example, a first preset threshold corresponding to the number of times of insufficient exposure of an image, a second preset threshold corresponding to the number of times of out-of-focus of the image, a third preset threshold corresponding to the number of times of deviation of a face image from a visual focus, and a fourth preset threshold corresponding to the number of times of occurrence of a hand shaking behavior), corresponding setting may be performed for each mobile terminal. For example, when the four preset thresholds are set for a certain mobile terminal, the mobile terminal may be used to capture a large number of images (i.e., photos) in advance and obtain the photographing parameters and image information corresponding to the large number of images, an image with a relatively ideal photographing effect is selected from the large number of images, and the average value of the photographing parameters of the selected image and the average value of the image information may be respectively used as the corresponding preset thresholds. For example, an average value of ISO values of the selected images serves as a preset sensitivity threshold, and an average value of luminance values of the selected images serves as a preset luminance threshold; selecting positions of adjacent pixels with high color contrast in the selected image as preset positions (for example, the number of the selected images is five, if the color contrast of adjacent pixels of four images in three positions, namely a first row, a third column, a fourth row, a fifth column, a fifth row, a fifth column, a seventh row, a sixth column, a seventh row and a seventh column, is high, the three positions can be selected as the preset positions), and taking the average value of the color contrast of the adjacent pixels in the selected image at the preset positions as a preset contrast threshold value; the average value of the shutter time lengths of the selected images is used as the preset shutter time length.

It should be noted that, although the camera in the mobile terminal can automatically adjust the shooting parameters of the camera according to the difference of the shooting scenes, the effect of the shot image may be unsatisfactory due to the bad shooting behavior of the user, at this time, the user can know the shooting habit of the user by looking up the shooting report, and improve the shooting level of the user according to the shooting suggestion in the shooting report, thereby improving the shooting quality.

In addition, since the shooting scenes are different, the shooting parameters of the camera acquired in step S101 may also be different. Therefore, in order to more accurately judge whether the photographing behavior of the user is a bad photographing behavior, different preset sensitivity thresholds and preset shutter durations can be set according to different shooting scenes. When determining whether the captured image is underexposed, it is necessary to first obtain a scene type to which the captured image belongs, obtain a corresponding preset sensitivity threshold according to the scene type, and then compare the ISO value of the captured image with the preset sensitivity. When judging whether a user shakes hands during photographing, the scene intensity of the photographed image needs to be acquired first, corresponding preset shutter duration is acquired according to the scene type, and then the shutter duration of the photographed image is compared with the preset shutter duration.

According to the embodiment of the invention, when the camera is started to shoot, the shooting parameters and/or the information of the shot images of the camera are/is acquired, the shooting behavior of the user is analyzed according to the shooting parameters and/or the information of the shot images, the analysis result is obtained, and the shooting report is generated according to the analysis result, so that the shooting habit of the user can be known by checking the shooting report, and the mobile terminal can provide corresponding shooting suggestions according to the shooting habit of the user, so that the shooting quality is improved.

Referring to fig. 2, which is a flowchart illustrating an implementation of a photographing behavior analysis method according to a second embodiment of the present invention, where the photographing behavior analysis method is applied to a mobile terminal, and as shown in the figure, the photographing behavior analysis method may include the following steps:

step S201, when the camera is started to photograph, acquiring photographing parameters of the camera and/or information of a photographed image.

The step is the same as step S101, and reference may be made to the related description of step S101, which is not repeated herein.

Step S202, according to the photographing parameters and/or the information of the photographed image, the photographing behavior of the user is analyzed, and an analysis result is obtained.

The step is the same as step S102, and reference may be made to the related description of step S102, which is not repeated herein.

Step S203, scoring the different analysis results respectively to obtain scores corresponding to the different analysis results respectively.

Compared with the first embodiment, the photographed report in the embodiment of the present invention not only includes the analysis result and the photographing suggestion corresponding to the analysis result, but also includes the score for each analysis result. In order to score each analysis result, the embodiment of the invention not only considers the poor photographing behavior of the user, but also considers the good photographing behavior of the user, namely, the analysis results are divided into exposure, focusing, composition and hand trembling.

In the embodiment of the invention, the mobile terminal can respectively score different analysis results, and a score range can be set for each analysis result in advance. For example, the score range of each analysis result is set to be 0-5, the image exposure can be set to be 5 normally, corresponding scores are set in the range of 0-4 according to the degree of underexposure, and the more serious the underexposure is, the lower the corresponding score is. The focusing accuracy can be set to be 5 minutes, corresponding scores are set in the range of 0-4 according to the degree of defocusing, and the more serious the defocusing is, the lower the corresponding score is. For composition, the human face image does not deviate from the visual focus by 5 minutes, corresponding scores are set in the range of 0-4 according to the degree of deviation from the visual focus, and the more serious the deviation from the visual focus is, the lower the corresponding score is. The user does not take place the hand trembling action when shooing and can set up to 5 minutes, sets up corresponding score in 0 ~ 4 within range according to the probability that takes place the hand trembling action, and the probability that takes place the hand trembling action is bigger, and corresponding score is lower.

When a user takes a picture by using the mobile terminal within a preset time (for example, one month), the frequency of possible occurrence of each analysis result is one or more times, and if the frequency is one, the score of the analysis result is the score of the analysis result; if the number of times is multiple, the score of the analysis result is the average value of the scores of the multiple analysis results. For example, if the user's photographing action results in the image being underexposed five times in a month, the score of the image being underexposed in a month is the average of the scores of the five image underexposures.

For the same analysis result, different score segments can be divided according to different shooting parameters related to the analysis result and/or different information of the shot image. That is, before step S201, the correspondence of different photographing parameters and/or different information of the photographed image with different scores is established.

Step S204, counting the total scores of different analysis results, and storing the total scores and the photographer level corresponding to the total scores in the photographing report.

In the embodiment of the present invention, the statistics may be performed to analyze the photographing behavior of the user when the user photographs within the preset time, and the obtained total scores of the different analysis results may be obtained by accumulating the scores of the different analysis results obtained in step S203, where the accumulated value is the total score. The corresponding relationship between the total score and the image capturing level may be preset before step S201, for example, 0 to 5 are primary photographers, 6 to 10 are middle photographers, 11 to 15 are advanced photographers, and 16 to 20 are advanced photographers.

The embodiment of the invention can grade the analysis result of the photographing behavior of the user, thereby judging which photographer level the user belongs to, and storing the judgment result in the photographing report, thereby facilitating the user to know the photographer level to which the photographing level of the user belongs by checking the photographing report.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
