Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a shooting prompt method provided by an embodiment of the present application. The photographing prompting method provided in the embodiment of the present application is applied to an electronic device, and the specific process may be as follows:

Step 101: Receive a photographing instruction, and obtain a scene image currently corresponding to the camera according to the photographing instruction.

In the embodiment of the present invention, the above-mentioned scene image may be obtained by the electronic device taking pictures of the current scene. Specifically, after receiving the photographing instruction input by the user, the electronic device may start the camera, and use the camera to take pictures of the current scene to obtain the scene. image. Wherein, the electronic device receives a photographing instruction input by the user, which may be a photographing instruction issued by the user through a preset button on the electronic device or a button or a combination of multiple buttons in the existing buttons; or, receiving a user through the touch screen of the electronic device. After receiving the photographing instruction input by the user, the electronic device obtains the scene image through the camera, and saves the image to prepare for subsequent processing.

In one embodiment, the electronic device can shoot through the built-in camera to obtain the original image, which may specifically include: the electronic device receives a start-up instruction for the built-in camera, responds to the instruction and starts the built-in camera, and when the camera is in the on state process. , and preview the external environment of the electronic device through the preview area to obtain an image of the previewed scene. In the process of displaying the preview image, the lens moves under the drive of the motor, and the photographed object is imaged on the image sensor through the lens. The image sensor converts optical signals into electrical signals through optical-electrical conversion and outputs them to the image processing circuit for subsequent processing. The image processing circuit may be implemented by hardware and/or software components, and may include various processing units that define an ISP (Image Signal Processing, image signal processing) pipeline.

In one embodiment, the above-mentioned built-in camera may be a single camera or a dual camera. For example, the dual camera may include a wide-angle camera and a telephoto camera, wherein the wide-angle camera may be used as the main camera of the electronic device, and the telephoto camera may be used as a secondary camera. Camera. When it is necessary to shoot an image of the scene where the electronic device is currently located, the electronic device can shoot only through its wide-angle camera module, or can shoot through its wide-angle camera and telephoto camera together. In other embodiments, it may also be three cameras, etc., which is not further limited in the present invention.

Step 102 , identifying multiple shooting objects in the scene image, and determining classification information of the multiple shooting objects respectively.

Specifically, in this embodiment of the present application, all objects in a scene image can be identified, for example, a preset image library stores a variety of objects and images taken from a variety of corresponding angles, and then the above scene images are respectively When the similarity of the comparison is greater than the preset value, it can be determined that the object corresponds to the sample in the image library, that is to say, the object can be identified. If the compared similarity is less than the preset value, it is determined that the object cannot be recognized. Therefore, the objects that can be recognized in the scene image can be taken as the shooting objects, and the other objects are not taken as the shooting objects. That is, the step of recognizing multiple shooting objects in the scene image includes:

identify all objects in the scene image;

According to the preset image library, a target object that can be used as a shooting subject among the objects is selected, and the target object is used as a shooting object.

The above process of recognizing objects in a scene image may include: 1. Image preprocessing, that is, image processing is mainly performed, including analog-to-digital conversion processing, binarization processing, image smoothing, transformation, enhancement, and restoration of the image to be captured. or filtering and other processing; 2. Extracting and selecting features of the image, for example, a 64×64 image can obtain 4096 data, and the original data in the measurement space of these 4096 data can be obtained by transforming the original data in the feature space. The features that reflect the nature of the classification; 3. Classify the features of the obtained image to determine the category of the image. Image recognition usually includes contour recognition, feature recognition, color recognition, material recognition, object recognition, etc. In the contour recognition, the contour of the object is mainly obtained according to information such as color and brightness, and then the content of the contour is determined according to the data corresponding to the contour.

In another embodiment, the shooting objects can also be identified based on the user's shooting habits, such as obtaining historical photos taken in the user's album, learning and analyzing the shooting objects that the user is more interested in, and then directly searching the scene images for the shooting objects that are related to the above-mentioned users. An object with a high similarity of the photographed object of interest can be determined as the photographed object in the scene image.

It should be noted that, the above-mentioned photographing objects may be one or more, and after the photographing objects are determined, the category information corresponding to each photographing object is further determined. For example, the types can be divided into: people, animals, plants, buildings and so on. When there are objects of the same type in the above-mentioned shooting objects, they can be distinguished by marking. For example, if there are two trees in the current scene, they can be marked as tree 1 and tree 2 respectively.

Step 103: Calculate the target zoom factor information of the multiple shooting objects according to the classification information.

In actual use, even for two different types of objects at the same distance, users often use different zoom magnifications when adjusting the focus. For example, when a user shoots a person 100m away, they will adjust the zoom magnification to a higher one. level, so as to see the outline of the person clearly, and if you shoot a house 100m away, the zoom factor will not be adjusted to a high level to see the overall situation of the house. Therefore, the proportions of different types of photographic objects displayed on the preview interface after zooming are also different. Therefore, in this embodiment, the optimal preview size of the object can be calculated according to the classification information of the object, and then the optimal preview size of the object can be calculated according to the optimal preview size of the object to achieve the same effect after zooming, that is, calculating Information about the target zoom factor of the subject.

In another embodiment, the distance information of the above-mentioned shooting object can also be obtained, for example, obtained by a depth-of-field camera, and then the zoom factor information of the shooting object is calculated according to the distance information of the shooting object, and the zoom factor of the shooting object is obtained on the basis of Then make corresponding adjustments according to its classification information. For example, the A classification will multiply the calculated zoom factor by 1.2, the B classification will multiply the calculated zoom factor by 0, and the C classification will multiply the calculated zoom factor by 0.8, etc. Take the final zoom factor as the target zoom factor.

Step 104 , respectively generating tags including target zoom factor information corresponding to the shooting objects, and displaying the tags as preview images at positions of multiple shooting objects in the scene image.

By respectively performing the above operations on the above-mentioned multiple photographing objects, the optimal zoom factor of each photographing object, that is, the target zoom factor, can be obtained. To make the solution more intuitive, in this embodiment, the target zoom factor of the shooting object may be directly placed in the scene image in the form of a label, for example, set at the corresponding shooting object position, and displayed as a preview image.

In one embodiment, after multiple tags are generated in the scene image, the image may be further down-sampled according to the current resolution of the screen, and then the down-sampled image is displayed on the screen of the electronic device. The image is down-sampled according to the current resolution of the screen, so that the resolution of the final preview image is consistent with the current resolution of the screen, and its display effect will not be reduced during display.

Further, since the target zoom ratios corresponding to the above-mentioned multiple subjects may be the same or different, for example, the zoom ratios corresponding to the subjects closer to the lens are relatively small, and the zoom ratios corresponding to the subjects farther away from the lens are all the same. It is relatively large, so in an embodiment, the shooting objects with the same target zoom factor in the current scene image can also be associated. For example, after a label corresponding to each object is generated in the scene image, the objects corresponding to the label containing the same target zoom factor are connected, or two labels with the same zoom factor can be connected. In other embodiments, prompts may also be provided by setting the same label color, for example, labels 2X are all set to red, labels 5X are all set to yellow, labels 10X are all set to blue, and so on.

As can be seen from the above, the shooting prompt method provided by the embodiment of the present application can receive a shooting instruction, obtain a scene image currently corresponding to the camera according to the shooting instruction, identify multiple shooting objects in the scene image, and determine the classification information of the multiple shooting objects respectively, According to the classification information, the target zoom factor information of the multiple shooting objects is calculated respectively, and the tags including the target zoom multiple information corresponding to the shooting objects are respectively generated, and the tags are displayed as preview images at the positions of the multiple shooting objects in the scene image. The embodiment of the present application can identify the shooting object in the scene image, calculate the corresponding target zoom factor information for each shooting object, and prompt the user in the form of a tag, thereby effectively improving the shooting efficiency when the user needs zoom shooting.

On the basis of the methods described in the foregoing embodiments, the photographing prompting method of the present application will be further introduced below. Referring to FIG. 2, FIG. 2 is another schematic flowchart of a shooting prompt method provided by an embodiment of the present application, and the shooting prompt method includes:

Step 201: Receive a photographing instruction, and obtain a scene image currently corresponding to the camera according to the photographing instruction.

In the embodiment of the present invention, the above-mentioned scene image may be obtained by the electronic device taking pictures of the current scene. Specifically, after receiving the photographing instruction input by the user, the electronic device may start the camera, and use the camera to take pictures of the current scene to obtain the scene. image.

Step 202: Identify multiple shooting objects in the scene image, and determine classification information of the multiple shooting objects respectively.

Specifically, in this embodiment of the present application, all objects in a scene image can be identified, for example, a preset image library stores a variety of objects and images taken from a variety of corresponding angles, and then the above scene images are respectively When the similarity of the comparison is greater than the preset value, it can be determined that the object corresponds to the sample in the image library, that is to say, the object can be identified. If the compared similarity is less than the preset value, it is determined that the object cannot be recognized. Therefore, the objects that can be recognized in the scene image can be taken as the shooting objects, and the other objects are not taken as the shooting objects. After the photographing objects are determined, category information corresponding to each photographing object is further determined. For example, the types can be divided into: people, animals, plants, buildings and so on.

Step 203: Determine the preview size corresponding to the classification information, and obtain the current original size of the shooting object in the scene image.

In one embodiment, the scales of different types of photographic objects displayed on the preview interface after zooming are also different. Therefore, in this embodiment, the best preview size of the object can be determined according to the classification information of the object, and then the original size of the object in the scene image can be obtained. The size of the subject.

Step 204: Calculate the target zoom factor information of the shooting object according to the preview size and the original size.

Specifically, calculating how many times the same effect can be achieved after zooming on the basis of the original size according to the optimal preview size of the photographing object, that is, calculating the target zoom factor information of the photographing object. In one embodiment, the preview size and the original size of the above-mentioned shooting object may be the proportion of the shooting object in the screen of the electronic device, for example, the optimal preview size is determined to be 60% of the area occupied by the shooting object on the screen, and In the current scene image, the shooting object occupies 20% of the screen area. According to the above two ratios, the target zoom factor of the shooting object can be calculated to be 3 times, and the best preview effect can be achieved. Among them, the above-mentioned optimal preview size can be determined according to the user's habit of browsing images, such as obtaining the area information adjusted by the user when browsing various types of shooting objects in a historical time period, and then determining each type of shooting objects according to the mean algorithm. According to the optimal area of the user, the optimal proportion information is calculated according to the optimal area and the screen area, as the preview size of the photographed object corresponding to each category, that is, to obtain the current original image of the photographed object in the scene image. Steps for sizing can include:

obtaining the current original area of the shooting object in the scene image;

The original ratio data of the shooting object is calculated according to the original area and the area of the screen of the electronic device, and is determined as the current original size of the shooting object in the scene image.

Further, the above-mentioned original size can also be determined by calculating the original area of the photographed object, and then calculating the current proportion information according to the original area and the screen area. That is to say, the step of obtaining the original size of the shooting object currently in the scene image may include:

obtaining the current original area of the shooting object in the scene image;

The original ratio data of the shooting object is calculated according to the original area and the area of the screen of the electronic device, and is determined as the current original size of the shooting object in the scene image.

Step 205 , respectively generating tags including target zoom factor information corresponding to the shooting objects, and displaying the tags as preview images at positions of multiple shooting objects in the scene image.

By respectively performing the above operations on the above-mentioned multiple photographing objects, the optimal zoom factor of each photographing object, that is, the target zoom factor, can be obtained. To make the solution more intuitive, in this embodiment, the target zoom factor of the shooting object may be directly placed in the scene image in the form of a label, for example, set at the corresponding shooting object position, and displayed as a preview image. As shown in FIG. 3 , FIG. 3 is a schematic diagram of a scene of a shooting prompt method provided by an embodiment of the present application. In this scene, people, trees, houses, mountains, etc. are included. The objects recognized by the processor include houses, people, tree 1 and tree 2. After calculating the target zoom factor of each of the above objects, the corresponding For example, the label corresponding to the house is "10X", the label corresponding to the person is "5X", the label corresponding to tree 1 is "5X", and the label corresponding to tree 2 is "15X". This picture can be used as a preview picture and displayed to the user, so that the user can see the optimal zoom factor for each subject at a glance. No need to debug back and forth.

Step 206, receiving the first operation of the user on the tag.

Step 207: Determine the target shooting object corresponding to the tag according to the first operation, adjust the target shooting object with the target zoom factor, and display the adjusted target shooting object as a preview image.

Further, after the label corresponding to each shooting object in the current scene is displayed on the preview interface, the corresponding shooting object can be zoomed according to the zoom factor corresponding to the label only by receiving the user's first operation on the label, and the The zoomed image is displayed on the screen. For example, the above-mentioned first operation can be a click operation. When the user clicks the "5X" label at the "person" position in Figure 3, the person can be zoomed in at 5x zoom, and the enlarged image preview value screen is displayed for display. User observation.

Step 208, receiving a second operation of the user on the tag.

Step 209 , according to the second operation, determine other shooting objects that have the same target zoom factor as the target shooting object, and switch the preview image to other shooting objects.

Further, since the target zoom ratios corresponding to the above-mentioned multiple subjects may be the same or different, for example, the zoom ratios corresponding to the subjects closer to the lens are relatively small, and the zoom ratios corresponding to the subjects farther away from the lens are all the same. It is relatively large, so in an embodiment, the shooting objects with the same target zoom factor in the current scene image can also be associated. Specifically, after step 207, the preview images of other shooting objects with the same zoom factor can be switched and displayed according to the second operation of the user.

For example, the above-mentioned second operation can be a double-click operation. After the user clicks the label "5X" at the "person" position, the person is zoomed in by 5 times and used as a preview image. At this time, the user double-clicks the screen to switch to "tree" 1" and zoom in on tree 1 with 5x zoom as a preview image. Since the zoom factor does not change before and after switching, the camera parameters do not need to be adjusted, and seamless switching of multiple subjects at the same zoom factor can be achieved.

As can be seen from the above, the shooting prompt method provided by the embodiment of the present application can receive a shooting instruction, obtain a scene image currently corresponding to the camera according to the shooting instruction, identify multiple shooting objects in the scene image, and determine the classification information of the multiple shooting objects respectively, Determine the preview size corresponding to the classification information, obtain the current original size of the shooting object in the scene image, calculate the target zoom factor information of the shooting object according to the preview size and the original size, and respectively generate a label containing the target zoom factor information corresponding to the shooting object , and display the label as a preview image at the positions of multiple shooting objects in the scene image, receive the user's first operation on the label, determine the target shooting object corresponding to the label according to the first operation, and use the target zoom factor to zoom in on the target shooting object. Adjust and display the adjusted target shooting object as a preview image, receive the user's second operation on the label, determine other shooting objects with the same target zoom factor as the target shooting object according to the second operation, and use the preview image Switch to another subject. The embodiment of the present application can identify the shooting object in the scene image, calculate the corresponding target zoom factor information for each shooting object, and prompt the user in the form of a label, so that when the user needs to zoom for shooting, the user can directly select the label by operating Yes, it greatly improves the efficiency of shooting.
