[0043] In order to more clearly understand the above-mentioned objects, features, and advantages of the present application, the solution of the present application will be further described below. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0044] In the following description, many specific details are set forth to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, rather than all of the embodiments.

[0045] The technical solutions provided by the embodiments of the present application will be introduced below in conjunction with examples.

[0046] Currently, taking photos has become one of the daily leisure and entertainment items for people. With the increasingly powerful photo-taking functions of photo-taking devices such as cameras and mobile phones, people can freely select various photo-taking functions to take photos to meet their own needs. In the prior art, the photos can be beautified and special effects can be added and other processing methods to make the photos more beautiful and interesting.

[0047] In view of the above prior art, in the embodiments of the present application, it is considered that: the above prior art is mainly based on the post-processing of the photos that have been taken, and the adjustment of the photo-taking angle and photo-taking parameters during the photo-taking process is also an important factor affecting the quality of the finished photos. And in order to determine the appropriate photo-taking angle and photo-taking parameters during the photo-taking process, usually the user needs to have proficient photography skills.

[0048] Therefore, an embodiment of the present application provides a photo-taking method. When this photo-taking method is applied to a photo-taking device, it can enable the photo-taking device to assist the user in determining the appropriate photo-taking angle and photo-taking parameters during the photo-taking process.

[0049] The following describes the specific implementation of the photographing method provided by the embodiments of the present application in combination with specific examples. The photographing method provided by the embodiments of the present application can be applied to a photographing device. In actual application, the functions of the above-mentioned photographing device can be implemented by various electronic devices with photographing functions. For example, the photographing device can specifically be an electronic device with photographing functions such as a camera, a mobile phone, an augmented reality (AR) / virtual reality (VR) device, etc. The specific form of the photographing device in the embodiments of the present disclosure may not be particularly limited.

[0050] The following takes the operation process of the photographing device as an example to introduce the photographing method provided by the embodiments of the present disclosure. As Figure 1 shown, the method may include:

[0051] S101. The photographing device obtains a first image in the photographing preview mode of the photographing device.

[0052] Among them, the photographing preview mode can be understood as: after the photographing function of the photographing device is turned on, the stage where the photographing device is in preparation for photographing. In the photographing preview mode, the photographing device can provide real-time feedback of the image collected by the current camera in the preview window for the user to observe.

[0053] For example, as Figure 2 shown, it is a schematic diagram of the interface of a photographing preview mode provided by the embodiments of the present application. It can be seen that the interface 20 in this photographing preview mode includes a preview window 201, and the preview window 201 can display the image collected by the camera in real time.

[0054] The first image can specifically be the image collected by the current camera. Taking Figure 2 as an example, the first image can be an image of two mountains and a house shown in the preview window 201.

[0055] It can be understood that in the photographing preview mode, since the image collected by the photographing device can be continuously updated over time, the first image can specifically be one of the multiple images collected by the photographing device. For example, in the photographing preview mode, the image currently collected by the camera can be obtained every preset time interval t, and this image can be used as the first image to execute the content of the method provided by the embodiments of the present application based on this first image. For another example, in the photographing preview mode, the image collected by the camera can also be detected. Whenever it is detected that the content of the image has changed too much, it is determined that the photographer has changed the shooting scene at this time, and then the image currently collected by the camera is re-used as the first image to execute the content of the method provided by the embodiments of the present application based on this first image.

[0056] S102. The photographing device determines a target sample corresponding to the first image feature from a preset sample set according to the first image feature of the first image.

[0057] Among them, the preset sample set includes multiple samples. Among them, the preset sample set may include multiple samples of different content types. For example, the preset sample set may include: samples of photographing people and samples of photographing landscapes, etc.

[0058] Among them, the first image feature may specifically be a feature parameter reflecting information such as the color, composition, and content of the first image.

[0059] In one implementation, the first image feature may specifically include: the first segmentation model diagram of the first image. Among them, the first segmentation model diagram is used to indicate the image area corresponding to the preset feature object in the first image.

[0060] For example, taking the first image shown in the preview window 201 of Figure 2 as an example, the first segmentation model diagram corresponding to the first image may be as shown in Figure 3 . Among them, the first segmentation model diagram may include the image area corresponding to the preset feature object "mountain" in the first image and the image area corresponding to the preset feature object "house".

[0061] Furthermore, the target sample corresponding to the first image feature may be the sample with the highest similarity between the image area corresponding to the preset feature object and the image area corresponding to the preset feature object indicated in the first segmentation model diagram. For example, when the first segmentation model diagram is as shown in Figure 3 , the target sample may be the sample with the highest similarity between the segmentation model diagram and the first segmentation model diagram.

[0062] In addition, in some implementations, the first image feature further includes: the content type of the first image and the 3A information of the first image.

[0063] For example, the content type of the first image may specifically be one of the preset multiple content types. For example, the preset multiple content types may include: people, landscapes, snow-capped mountains, blue skies, grasslands, and deserts, etc. The content type of the first image may be one of the above content types.

[0064] The 3A information includes: parameter information of autofocus, autoexposure, and auto white balance.

[0065] Furthermore, the target sample corresponding to the first image feature can be the sample with the highest similarity in content type and 3A information to the content type and 3A information of the first image. For example, for each sample in the preset sample set, the first similarity between the content type of the sample and the content type of the first image, and the second similarity between the 3A information of the sample and the 3A information of the first image can be calculated respectively. Then, the first similarity and the second similarity are weighted and summed to obtain the similarity between the sample and the first image. Then, the sample with the highest similarity to the first image in the preset sample set is used as the target sample.

[0066] S103. The photographing device displays a prompt mark corresponding to the target sample in the preview window.

[0067] The prompt mark is used to prompt the user to change the photographing angle of the photographing device by using the prompt mark.

[0068] In one implementation, the prompt mark is specifically used to indicate the position of a preset feature object in the picture.

[0069] Exemplarily, as Figure 4 shown, in the preview window 201 of the photographing device, three prompt marks are displayed, namely, prompt mark 202a, prompt mark 202b, and prompt mark 202c. Among them, prompt mark 202a is used to indicate the position of the preset feature object "mountain" in the picture, prompt mark 202b is used to indicate the position of the preset feature object "house" in the picture, and prompt mark 202c is used to indicate the position of the preset feature object "person" in the picture. In this way, the user can use these prompt marks to change the photographing angle of the photographing device so that the "mountain", "house", and "person" are respectively placed at the positions corresponding to the respective prompt marks in the picture.

[0070] It can be understood that Figure 4 only the text - box with text is taken as an example of the prompt mark for illustration. In the actual application process, the prompt mark can also adopt other forms. For example, a picture of a mountain can be used as the prompt mark for the preset feature object "mountain", a picture of a house can be used as the prompt mark for the preset feature object "house", and so on. The specific form of the prompt mark can be not limited in the embodiments of the present application.

[0071] In another implementation, the prompt mark is specifically used to indicate the direction for the user to move the photographing angle.

[0072] Exemplarily, as Figure 5 shown, in the preview window 201 of the photographing device, a prompt mark 203 is displayed, which is used to indicate that the user moves the photographing angle to the right. In this way, the user can move the photographing angle to the right according to the prompt mark 203 so that the photographing angle corresponds to the photographing angle of the target sample.

[0073] In some implementations, such as Figure 6 As shown, in the method provided by the embodiments of the present application, S102 may specifically include:

[0074] S1021. The photographing device determines n sample images corresponding to the first image feature from a preset sample image set, where n is a positive integer greater than 1.

[0075] For example, the n sample images may be: the n sample images with the highest similarity between the image region corresponding to the preset feature object and the image region corresponding to the preset feature object indicated in the first segmentation model diagram. For example, when the first segmentation model diagram is as Figure 3 As shown, the target sample images may be the n sample images with the highest similarity between the segmentation model diagram in the preset sample image set and the first segmentation model diagram.

[0076] For another example, the n sample images may be: the n sample images with the highest similarity between the content type and 3A information and the content type and 3A information of the first image. For example, for each sample image in the preset sample image set, the first similarity between the content type of the sample image and the content type of the first image, and the second similarity between the 3A information of the sample image and the 3A information of the first image can be calculated respectively, and then the first similarity and the second similarity are weighted and summed to obtain the similarity between the sample image and the first image. Then, the n sample images with the highest similarity to the first image are determined from the preset sample image set.

[0077] S1022. The photographing device displays the n sample images in the interface of the photographing preview mode.

[0078] S1023. The photographing device determines the target sample image in response to a first user operation of selecting a target sample image from the n sample images.

[0079] Exemplarily, in the interface of the photographing preview mode as Figure 7 As shown, the n sample images (including sample image a, sample image b, sample image c, and sample image d in the figure) may be displayed in area 204. Then, after the photographing device receives the first user operation, it determines the target sample image from sample image a, sample image b, sample image c, and sample image d.

[0080] It can be understood that in Figure 7Among them, only by way of example, taking sample a, sample b, sample c, and sample d as examples, a possible form of displaying n samples in the interface of the camera preview mode is introduced. In the actual application process, the n samples can also be displayed in the interface of the camera preview mode in other forms. For example, the n samples can be tiled and displayed in the interface of the camera preview mode in a multi-row and multi-column manner; for another example, when the n samples also include other samples in addition to sample a, sample b, sample c, and sample d, in area 204, the user can switch to other samples by swiping left and right, etc. The embodiments of the present application may not limit the display manner of the n samples in the interface of the camera preview mode.

[0081] In some implementation manners, as Figure 8 shown, the method may further include:

[0082] S104. The photographing device adjusts the photographing parameters of the photographing device according to the photographing parameters corresponding to the target sample.

[0083] Among them, the photographing parameters include one or more of an exposure compensation parameter, an ISO, a shutter speed, a white balance parameter, and a focusing distance.

[0084] For example, after the photographing device determines the target sample according to S102, the photographing parameters of the photographing device can be set to the photographing parameters corresponding to the target sample. For another example, after the photographing device determines the target sample according to S102, based on the current photographing parameters of the photographing device, the photographing parameters of the photographing device can be adjusted accordingly according to the photographing parameters corresponding to the target sample, so that the photographing parameters of the photographing device are closer to the photographing parameters corresponding to the target sample.

[0085] In some designs, as Figure 9 shown, the method may further include:

[0086] S105. When the photographing device detects that there is a first parameter in the photographing parameters corresponding to the target sample and the current photographing parameters of the photographing device whose difference is greater than a threshold, a control for adjusting the first parameter is displayed in the interface of the camera preview mode, and an interface highlighting process is performed on the control for adjusting the first parameter.

[0087] Among them, the current photographing parameters of the photographing device can be specifically understood as: the photographing parameters of the photographing device before adjusting the photographing parameters of the photographing device according to the photographing parameters corresponding to the target sample.

[0088] For example, taking the ISO value in the camera parameters as an example, assume that the current ISO value in the camera device is 800, and the ISO value corresponding to the target sample is 163. If the camera device detects that the difference between the ISO value corresponding to the target sample and the current ISO value of the camera device is greater than a preset threshold (for example, if the preset threshold is 200, then the difference between 800 and 163 is greater than 200, that is, the difference between the ISO value corresponding to the target sample and the current ISO value of the camera device is greater than the preset threshold), then the first parameter is the ISO value. Furthermore, as Figure 10 shown, in the interface of the camera preview mode, an adjustment control 204 corresponding to the ISO value is displayed. The ISO value shown in the adjustment control 204 is 163, indicating that the ISO value of the camera device has been adjusted to the ISO value corresponding to the target sample. And the interface of the adjustment control 204 corresponding to the ISO value is highlighted. It can be seen that compared with the other adjustment controls on the left and right, the adjustment control 204 is highlighted in the form of a block diagram. In this way, it is convenient for the user to know the current ISO value situation.

[0089] In some possible designs, as Figure 11 shown, the method may further include:

[0090] S106. The camera device receives a second user operation on the adjustment control corresponding to the first parameter.

[0091] S107. The camera device displays an adjustment axis corresponding to the first parameter and marks the position of the target value on the adjustment axis.

[0092] Wherein, the position of the target value is: the position corresponding to the value of the first parameter in the current camera parameters.

[0093] Continuing Figure 10 shown in the example where the ISO value is the first parameter, when the camera device receives a click operation on Figure 10 the area 204 (which can be understood as the second user operation), as Figure 12 shown, an adjustment axis 205 corresponding to the ISO value is displayed in the interface, and the position of the ISO value 800 (i.e., the position of the target value) is marked on the adjustment axis 205. In this way, it is convenient for the user to know the value of the first parameter (the ISO value in this example) before adjusting the camera parameters of the camera device according to the camera parameters corresponding to the target sample.

[0094] Based on the same inventive concept, as an implementation of the above method, an embodiment of the present application further provides a camera device. This embodiment corresponds to the foregoing method embodiment. For the convenience of reading, the details in the foregoing method embodiment will not be described one by one in this embodiment, but it should be clear that the camera device in this embodiment can correspondingly implement all the contents in the foregoing method embodiment.
