[0031] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0032] The photographing method, device, electronic device, chip and storage medium of the embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0033] Figure 1 The present invention is a flowchart of a photographing method provided by an embodiment of the present invention.

[0034] The embodiment of the present disclosure takes the photographing method being configured in a photographing device as an example. The photographing device can be applied to any electronic device so that the electronic device can provide the best composition plan when photographing, and crop and enhance the quality of the image after photographing.

[0035] like Figure 1 As shown, the photographing method may include the following steps:

[0036] Step 101: Determine a second shooting parameter according to a first shooting parameter corresponding to the current preview image.

[0037] In the disclosed embodiment, when any lens (such as a wide-angle lens, a telephoto lens, etc.) is selected in an electronic device with a camera function (such as a mobile phone, etc.) to prepare to take a photo, the current preview screen, that is, the screen captured by the current lens, can be displayed in the interface of the electronic device, and the first shooting parameter corresponding to the preview screen is the shooting parameter of the currently selected lens.

[0038] In the embodiment of the present disclosure, the second shooting parameter may be a shooting parameter determined after adjustment based on the first shooting parameter. Since in the present disclosure, the second shooting parameter is a shooting parameter used to help the user select the optimal composition for shooting online, the second shooting parameter should be able to capture a clearer subject than the first shooting parameter, so the second shooting parameter and the first shooting parameter should satisfy that the focal length value in the second shooting parameter is greater than the focal length value in the first shooting parameter, etc.

[0039] Step 102: Capture a first image based on a second shooting parameter.

[0040] The shooting range corresponding to the first image is smaller than the shooting range corresponding to the second image acquired based on the first shooting parameter.

[0041] It is understandable that the shooting range corresponding to the first image is smaller, which can ensure that the details of the subject in the captured picture are clearer, making it easier to analyze the shot scene and determine the best shooting composition.

[0042] In the disclosed embodiment, after the second shooting parameter is determined, the camera may be allowed to shoot a photo using the second shooting parameter to acquire the first image.

[0043] It should be noted that, since the focal length of a telephoto lens is longer than that of a general lens, it has the characteristics of a relatively small viewing angle and a clear subject, so in the present disclosure, the second shooting parameter may also be a shooting parameter of the telephoto lens. The telephoto lens may be called to take a photo to acquire the first image.

[0044] Step 103: Analyze the first image to obtain a composition strategy corresponding to the first image.

[0045] In the disclosed embodiment, the first image can be input into the model for analysis, and the model analyzes the scene and the photographed object in the first image to determine which composition will produce a better photo effect, thereby obtaining a composition strategy output by the model. Alternatively, the existing image cropping scheme can be used, such as using computer aesthetic scoring to select the window with the highest aesthetic score from a number of sliding windows for cropping, etc., to complete the analysis of the first image, and determine the cropping scheme with the highest score as the composition strategy corresponding to the first image. Alternatively, the preset composition strategy corresponding to the type of subject in the first image, such as people, food, buildings, etc., can be determined.

[0046] It should be noted that when using the model to analyze the first image, the model can be a neural network based on the deep learning algorithm YOLOv5 structure, which can output multiple candidate boxes and the confidence corresponding to each candidate box. The confidence is used to represent the model's aesthetic score for the image in the candidate box. The model can then select the candidate box with the highest confidence among multiple candidate boxes as the best composition box, and output the composition strategy corresponding to the first image according to the position of the best composition box in the first image.

[0047] Optionally, the composition strategy may include at least one of the following: a composition frame position, a position of a photographed object, a positional relationship between photographed objects, and a photographing mode.

[0048] The composition frame is the frame range recommended for users to take photos, which can be a square frame, and the composition frame position is the position of the composition frame in the current preview screen. The position of the photographed object refers to the position information of the photographed object relative to the composition frame, for example, it can be the lower left corner of the composition frame, etc.

[0049] It should be noted that when the shooting picture contains two or more shooting objects, the composition strategy can also include the position relationship between the shooting objects to describe the position relationship in which the multiple shooting objects should be shot, such as a person on the left side of a tree, etc. In addition, the shooting mode in the composition strategy can be any one of the portrait mode, flash mode, sports mode, etc., and the shooting model can be determined by the type of the shooting subject.

[0050] In the disclosed embodiment, by generating a composition strategy based on at least one of the position of the composition frame, the position of the photographed object, the positional relationship between the photographed objects, and the shooting mode, the flexibility and reliability of the model in guiding the shooting composition can be improved, thereby optimizing the user experience.

[0051] Step 104: Display the composition strategy on the preview screen.

[0052] In the disclosed embodiments, the composition strategy may be displayed in the preview screen, so that the user can intuitively obtain guidance information on the shooting composition. Specifically, when the composition strategy includes the position of the composition frame, a square frame may be displayed at the corresponding position in the photo preview screen, so that the user can determine the effect of the photo taken with the composition strategy. Alternatively, when the composition strategy includes the position of the photographed object and the positional relationship between the photographed objects, it may be displayed in the preview screen in the form of text. Alternatively, when the composition strategy includes the shooting mode, words such as "recommended to use...shooting mode" may be displayed on the preview screen.

[0053] Step 105 : In response to a confirmation operation of the user, a third image is captured based on the composition strategy.

[0054] In the embodiment of the present disclosure, when the preview screen displays the composition strategy, a control for determining to take a photo with the composition strategy may also be displayed. When the control is triggered, the user's confirmation operation may be responded to, and then the composition strategy may be used to take a photo, thereby capturing the third image.

[0055] In the disclosed embodiment, first, the second shooting parameter is determined according to the first shooting parameter corresponding to the current preview screen. Then, based on the second shooting parameter, the first image is captured, and the first image is analyzed to obtain the composition strategy corresponding to the first image. Afterwards, the composition strategy is displayed on the preview screen, and in response to the user's confirmation operation, the third image is captured based on the composition strategy. Thus, by pre-capturing an image using a shooting parameter with a larger focal length than the current shooting parameter, parsing the pre-captured image, the composition strategy is obtained, and the composition strategy is recommended to the user for taking pictures. Automated intelligent composition for taking pictures can be achieved, which helps users take pictures with better composition, helps to ensure imaging quality, and improves the user's photo-taking experience.

[0056] Figure 2 A schematic diagram of a process of taking a photo provided by an embodiment of the present disclosure is shown in FIG. Figure 2 As shown, the photographing method may include the following steps:

[0057] Step 201: determine the type of the photographed object contained in the preview image.

[0058] The type of the photographed object may include one or more of plants, buildings, people, etc.

[0059] In the embodiment of the present disclosure, the type of each photographed object may be determined by identifying all objects in the preview picture, and the types of all photographed objects included in the preview picture may be the same or different.

[0060] Step 202: Determine the updating granularity of the shooting parameters according to the type of the object being shot.

[0061] The updating granularity of the shooting parameters may be the reducing granularity of the shooting field of view, or the increasing granularity of the focal length, and so on.

[0062] It should be noted that, since different types of photographed objects have different sizes and feature complexity, different shooting parameters need to be adjusted to allow the photographed object to be completely photographed or the features of the photographed object to be clearly photographed. For example, when the photographed object is an insect, the focal length in the shooting parameters needs to be greatly increased, and the update granularity of the shooting parameters is relatively large.

[0063] Therefore, in the present disclosure, a mapping relationship between different types of photographed objects and the granularity of updating photographing parameters can be preset, so that after determining the type of the current photographed object, the granularity of updating the photographing parameters can be determined directly according to the mapping relationship.

[0064] Step 203: Determine a second shooting parameter based on the shooting parameter update granularity and the first shooting parameter.

[0065] In this embodiment, different granularities of reducing the field of view or increasing the focal length are used for different types of photographed objects to update the shooting parameters, thereby making the field of view of the acquired first image more accurate.

[0066] Step 204: Capture the first image based on the second shooting parameter.

[0067] Step 205: Analyze the first image to obtain a composition strategy corresponding to the first image.

[0068] Step 206: Display the composition strategy on the preview screen.

[0069] For detailed description of the above steps 204 to 206, reference can be made to other embodiments of the present disclosure and will not be repeated here.

[0070] Step 207 : if no confirmation instruction for the composition strategy is received and a photographing instruction is received, a second image is acquired based on the first photographing parameter.

[0071] In the disclosed embodiment, after the preview screen displays the composition strategy, the user can also choose not to use the composition strategy, but directly shoot the current preview screen. Therefore, when no confirmation instruction for the composition strategy is received and a shooting instruction is received, the first shooting parameter can be used to shoot and the second image can be acquired.

[0072] Step 208: store the first image and the second image in association with each other.

[0073] In the disclosed embodiment, the first image and the second image may be stored in association, so that the first image can be used to enhance the quality of the second image in the subsequent offline state. Alternatively, because the user did not use the recommended composition strategy to take a photo, it may indicate that the first image does not meet the user's personal aesthetic taste. In this case, the first image and the second image may be stored in association as training data for the first model to update the first model parameters, so that the updated first model can generate a composition strategy that better meets the user's needs, thereby improving the efficiency of taking photos.

[0074] In this embodiment, by capturing the second image based on the first shooting parameters and storing the first image in association with the second image when no confirmation instruction for the composition strategy is received and a shooting instruction is received, the shooting method provided by the present disclosure is made more perfect, providing conditions for subsequent enhancement of image quality and optimization of model parameters.

[0075] Figure 3 FIG. 1 is a flow chart of a photographing method provided by another embodiment of the present disclosure. Figure 3 As shown, the photographing method may include the following steps:

[0076] Step 301 , in response to a cropping operation on any image, any image is parsed to obtain a plurality of candidate frames corresponding to any image.

[0077] Among them, any image can be any final captured image obtained by the method of the above embodiment, that is, it can be the first image or the second image, or it can be any image in the device album.

[0078] Among them, each candidate box is a way to crop the image.

[0079] In the embodiment of the present disclosure, after receiving the cropping instruction of the user for any image, the cropping operation for the any image can be responded to, and the any image can be parsed first. Specifically, the any image can be input into the model, and the model can be used to parse the image to obtain multiple candidate frames for cropping the image output by the model. Alternatively, multiple candidate frames can be determined based on the subject and subject type in the any image, and the present disclosure does not limit this.

[0080] It should be noted that when the model is used to parse the image, the model can be used to crop regions of different shapes and sizes from the image, and each region corresponds to a candidate box. The model used at this time can have the same structural design as the model for parsing the image during the photo shooting process in the above embodiment, but the model for parsing the image after taking the photo can have a deeper network layer and a wider number of channels, and the cropping effect of the output box is better, more accurate and takes longer.

[0081] Step 302: Determine a score corresponding to each candidate box based on multiple candidate boxes and any image.

[0082] In the disclosed embodiment, multiple candidate boxes and any image may be input into a model for aesthetic quality evaluation to obtain a score corresponding to each candidate box output by the model.

[0083] It should be noted that the model used for aesthetic quality evaluation can be composed of a visual geometry group network VGGNet and a mask region convolutional neural network (Mask Region-based Convolutional Neural Network, Mask R-CNN). After multiple candidate boxes and any image are input into the model, the segmentation map of each candidate box for any image can be obtained by passing through Mask R-CNN, and then the segmentation map and the RGB image of any image are input into VGGNet to obtain the aesthetic score corresponding to each candidate box.

[0084] Step 303: crop any image based on the corresponding candidate frame with the highest score to obtain a first optimized image corresponding to any image.

[0085] In this embodiment, by using a model to determine multiple cropping candidate frames corresponding to an image, and using the model to score the partial image corresponding to each cropping candidate frame, the candidate frame with the highest score is used to complete the cropping of the image. This can crop out unimportant parts of the image, highlight the main body of the image, enhance the visual effect of the image and the efficiency of conveying information, and improve image quality.

[0086] Figure 4 FIG. 1 is a flow chart of a photographing method provided by another embodiment of the present disclosure. Figure 4 As shown, the photographing method may include the following steps:

[0087] Step 401: In response to an enhancement operation on any image, an associated image corresponding to any image is determined.

[0088] Among them, any image may be the first image or the second image collected in the above embodiment, or may be a cropped image. Then the associated image corresponding to the any image may be another image stored in association with the any image, for example, when any image is the first image, the associated image is the second image stored in association, or may be the image before cropping corresponding to any image.

[0089] In an embodiment of the present application, a user can select an image for quality enhancement as needed, and can respond to the enhancement operation on any image. Since the associated image corresponding to any image contains the same photographed object as any image, the associated image corresponding to any image can be used to enhance the quality of the image selected by the user.

[0090] Step 402: Obtain a second optimized image corresponding to any image according to any image and the associated images.

[0091] In the disclosed embodiment, any image and associated images may be respectively input into a model for enhancing image features to obtain a second optimized image corresponding to any image output by the model.

[0092] It should be noted that the model used to enhance image features can be a U-shaped network (UNet) structure, which can enhance features such as edges, textures, contrast, etc. in the image. Specifically, the model can extract and fuse features of any image and related images, and output a second optimized image corresponding to any image.

[0093] In this embodiment, by utilizing the model and combining the associated images of the image to be enhanced, the image enhancement result is obtained, which can further enhance the quality of the photographing result and optimize the user experience.

[0094] In order to implement the above embodiments, the present disclosure also proposes a photographing device.
