However, while the principles of the application have been described in language specific to above, it is not intended to be limited to the specific form set forth herein, and it will be recognized by those of ordinary skill in the art that various of the steps and operations described below may be implemented in hardware.

The terms "first", "second", and "third", etc. in this application are used to distinguish between different objects and not to describe a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to only those steps or modules listed, but rather, some embodiments may include other steps or modules not listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1, fig. 1 is a schematic flow chart of a shooting prompting method according to an embodiment of the present disclosure. The shooting prompting method provided by the embodiment of the application is applied to electronic equipment, and the specific process can be as follows:

step 101, receiving a photographing instruction, and acquiring a scene image currently corresponding to the camera according to the photographing instruction.

In the embodiment of the present invention, the scene image may be obtained by taking a picture of the current scene by the electronic device, and specifically, after receiving a picture taking instruction input by a user, the electronic device may start a camera, and take a picture of the current scene by using the camera to obtain the scene image. The electronic equipment receives a photographing instruction input by a user, and can receive the photographing instruction sent by the user through a preset button on the electronic equipment or one or a combination of a plurality of existing buttons; or, receiving photographing request information sent by a user through a touch screen of the electronic device (for example, clicking a "photographing" button in a screen), and after receiving a photographing instruction input by the user, the electronic device obtains a scene image through a camera and stores the image to prepare for subsequent processing.

In an embodiment, the electronic device may capture an original image through a built-in camera, and specifically includes: the electronic equipment receives a starting instruction of the built-in camera, responds to the instruction and starts the built-in camera, and previews the external environment of the electronic equipment through the preview area in the process that the camera is in the starting state so as to obtain the image of the previewed scene. In the process of displaying the preview image, the lens is driven by the motor to move, and a photographed object is imaged on the image sensor through the lens. The image sensor converts the optical signal into an electric signal through optical-electric conversion and transmits the electric signal to the image processing circuit for subsequent processing. The Image Processing circuit may be implemented using hardware and/or software components, and may include various Processing units that define an ISP (Image Signal Processing) pipeline.

In an embodiment, the built-in camera may be a single camera or may be two cameras, for example, the two cameras may include a wide-angle camera and a telephoto camera, wherein the wide-angle camera may be used as a main camera of the electronic device, and the telephoto camera may be used as a sub-camera. When the image of the current scene of electronic equipment is shot to needs, this electronic equipment can only shoot through its wide-angle camera module, also can shoot with long burnt camera jointly through its wide-angle camera. In other embodiments, three cameras may be used, and the present invention is not limited in this respect.

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

Specifically, in the embodiment of the present application, all objects in the scene image may be identified, for example, a plurality of objects and images captured at a plurality of corresponding angles are stored in a preset image library, then the objects in the scene image are respectively compared, and when the compared similarity is greater than a preset value, it may be determined that the object corresponds to a sample in the image library, that is, the object may be identified. And if the compared similarity is smaller than a preset value, determining that the object cannot be identified. Therefore, objects that can be recognized in the scene image can be taken as the photographic subject, and the rest of the objects are not taken as the photographic subject. That is, the step of identifying a plurality of photographic subjects in the scene image includes:

identifying all objects in the scene image;

and selecting a target object which can be used as a shooting subject from the objects according to a preset image library, and using the target object as a shooting object.

The process of identifying objects in the scene image may include: the method comprises the following steps of firstly, preprocessing an image, namely mainly carrying out image processing, including analog-to-digital conversion processing, binarization processing, smoothing, transformation, enhancement, restoration or filtering and the like on the image to be shot; extracting and selecting the features of the image, for example, 4096 data can be obtained from a 64 × 64 image, and the features which can reflect the nature of classification in the feature space can be obtained from the raw data of the 4096 data in the measurement space through transformation; and thirdly, classifying the characteristics of the obtained image and determining the category of the image. Image recognition generally includes contour recognition, feature recognition, color recognition, material recognition, object recognition, and the like. In the contour recognition, the contour of an object is mainly obtained according to information such as color, brightness and the like, and then, what object or what feature the contents of the contour are is determined according to data corresponding to the contour.

In another embodiment, the shooting object may also be identified based on the shooting habit of the user, for example, historical photos taken in a user album are obtained, it is known through learning analysis that the user is interested in the shooting object, and then an object with higher similarity to the shooting object that the user is interested in is directly searched in the scene image, that is, the shooting object in the scene image may be determined.

It should be noted that there may be one or more objects to be photographed, and after the objects to be photographed are determined, category information corresponding to each object to be photographed is further determined. For example, the categories can be divided into: humans, animals, plants, buildings, and the like. When there are objects of the same type in the above shot objects, the shot objects can be distinguished by labels, for example, when there are two trees in the current scene, the shot objects can be labeled as tree 1 and tree 2, respectively.

And 103, respectively calculating target zoom multiple information of a plurality of shot objects according to the classification information.

In practical use, even two different kinds of objects with the same distance are used, different zoom multiples are often used for focusing by a user, for example, when the user takes a photo of a person other than 100m, the zoom multiple is adjusted to a higher level so as to see the outline of the person clearly, and when the user takes a photo of a house other than 100m, the zoom multiple is not adjusted to be high so as to see the whole situation of the house clearly. Therefore, the proportions of different kinds of photographic subjects presented on the preview interface after zooming are 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 how many times of zooming can achieve the same effect can be calculated according to the optimal preview size of the object, that is, the target zoom factor information of the object is calculated.

In another embodiment, the distance information of the object may also be obtained, for example, by a depth camera, then the zoom factor information of the object is calculated according to the distance information of the object, and corresponding adjustment is performed according to the classification information of the object on the basis of obtaining the zoom factor of the object, for example, the a classification multiplies the calculated zoom factor by 1.2, the B classification multiplies the calculated zoom factor by 0, the C classification multiplies the calculated zoom factor by 0.8, and the like, and the final zoom factor is used as the target zoom factor.

And 104, respectively generating labels containing target zoom multiple information corresponding to the shot objects, and displaying the labels at a plurality of shot object positions in the scene image as preview images.

The above operations are performed on the plurality of shot objects respectively, so that the optimal zoom multiple of each shot object, that is, the target zoom multiple, can be obtained. In order to make the scheme more intuitive, the present embodiment may also directly place the target zoom multiple of the photographic subject in the form of a tag in the scene image, for example, at the corresponding position of the photographic subject, and display the target zoom multiple as a preview image.

In an embodiment, after the plurality of 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 subjected to down-sampling processing 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 the display effect of the final preview image is not reduced during display.

Further, since the target zoom multiples corresponding to the plurality of objects may be the same or different, for example, the zoom multiples corresponding to the objects closer to the lens are smaller, and the zoom multiples corresponding to the objects farther from the lens are larger, in an embodiment, the objects having the same target zoom multiple in the current scene image may be associated. For example, after generating a tag corresponding to each object in the scene image, the objects corresponding to the tags including the same target zoom factor may be connected, or two tags having the same zoom factor may be connected. In other embodiments, the prompt may also be performed by setting the same label color, for example, the labels 2X are all set to red, the labels 5X are all set to yellow, the labels 10X are all set to blue, and so on.

As can be seen from the above, the shooting prompting method provided in the embodiment of the present application may receive a shooting instruction, obtain a scene image corresponding to the camera currently according to the shooting instruction, identify a plurality of shooting objects in the scene image, respectively determine classification information of the plurality of shooting objects, respectively calculate target zoom multiple information of the plurality of shooting objects according to the classification information, respectively generate tags including the target zoom multiple information corresponding to the shooting objects, and display the tags at positions of the plurality of shooting objects in the scene image as preview images. According to the embodiment of the application, the shooting objects in the scene image can be identified, the corresponding target zooming multiple information of each shooting object is calculated, and the user is prompted in a label mode, so that when the user needs zooming shooting, the shooting efficiency is effectively improved.

The shooting prompting method of the present application will be further described below on the basis of the method described in the above embodiment. Referring to fig. 2, fig. 2 is another schematic flow chart of a shooting prompting method provided in the embodiment of the present application, where the shooting prompting method includes:

step 201, receiving a photographing instruction, and acquiring a scene image currently corresponding to the camera according to the photographing instruction.

In the embodiment of the present invention, the scene image may be obtained by taking a picture of the current scene by the electronic device, and specifically, after receiving a picture taking instruction input by a user, the electronic device may start a camera, and take a picture of the current scene by using the camera to obtain the scene image.

Step 202, a plurality of shooting objects in the scene image are identified, and classification information of the plurality of shooting objects is determined respectively.

Specifically, in the embodiment of the present application, all objects in the scene image may be identified, for example, a plurality of objects and images captured at a plurality of corresponding angles are stored in a preset image library, then the objects in the scene image are respectively compared, and when the compared similarity is greater than a preset value, it may be determined that the object corresponds to a sample in the image library, that is, the object may be identified. And if the compared similarity is smaller than a preset value, determining that the object cannot be identified. Therefore, objects that can be recognized in the scene image can be taken as the photographic subject, and the rest of the objects are not taken as the photographic subject. After the photographic subject is determined, category information corresponding to each photographic subject is further determined. For example, the categories can be divided into: humans, animals, plants, buildings, and the like.

Step 203, determining the preview size corresponding to the classification information, and acquiring the original size of the current shot object in the scene image.

In one embodiment, the different types of subjects are presented in different proportions on the preview interface after zooming. Therefore, in this embodiment, the optimal preview size of the object may be determined according to the classification information of the photographic object, and then the original size of the photographic object in the scene image is obtained, where the original size is the size of the photographic object in the scene image when the scene image is directly previewed.

And step 204, calculating target zoom multiple information of the shooting object according to the preview size and the original size.

Specifically, the same effect can be achieved after zooming by several times on the basis of the original size is calculated according to the optimal preview size of the photographic object, that is, the target zooming multiple information of the photographic object is calculated. In an embodiment, the preview size and the original size of the photographic subject may be a ratio of the photographic subject in the screen of the electronic device, for example, the optimal preview size is determined to be 60% of an area occupied by the photographic subject in the screen, and the area occupied by the photographic subject in the current scene image in the screen is 20%, and the target zoom multiple of the photographic subject is calculated to be 3 times according to the two ratios, that is, the optimal preview effect can be achieved. The above-mentioned optimal preview size may be determined according to a usage habit of a user browsing an image, for example, obtaining area information adjusted when the user browses various types of photographic objects in a historical time period, then determining an optimal area of each type of photographic object for the user according to a mean algorithm, and then calculating optimal proportion information according to the optimal area and a screen area, so as to serve as a preview size of the photographic object corresponding to each type, that is, the step of obtaining an original size of the photographic object in a scene image at present may include:

acquiring the original area of the current shot object in the scene image;

and calculating the original proportion data of the shot object according to the original area and the area of the screen of the electronic equipment, and determining the original size of the shot object in the scene image at present.

Further, the original size may be determined by calculating an original area of the subject, and then calculating current ratio information according to the original area and the screen area. That is, the step of obtaining the original size of the photographic subject currently in the scene image may include:

acquiring the original area of the current shot object in the scene image;

And step 205, generating labels containing target zoom multiple information corresponding to the shot objects respectively, and displaying the labels at a plurality of shot object positions in the scene image as preview images.

The above operations are performed on the plurality of shot objects respectively, so that the optimal zoom multiple of each shot object, that is, the target zoom multiple, can be obtained. In order to make the scheme more intuitive, the present embodiment may also directly place the target zoom multiple of the photographic subject in the form of a tag in the scene image, for example, at the corresponding position of the photographic subject, and display the target zoom multiple as a preview image. As shown in fig. 3, fig. 3 is a scene schematic diagram of a shooting prompting method provided in the embodiment of the present application. The scene includes characters, trees, houses, mountains and the like, the shooting objects obtained through recognition by the processor include houses, people, trees 1 and trees 2, and after the target zoom multiple of each shooting object is calculated respectively, corresponding labels are placed at the shooting object positions, for example, the label corresponding to the house is "10X", the label corresponding to the people is "5X", the label corresponding to the tree 1 is "5X", and the label corresponding to the tree 2 is "15X". The picture can be used as a preview picture and displayed to a user, so that the user can see the optimal zoom multiple of each shot object at a glance. No back and forth debugging is required.

Step 206, receiving a first operation of the user for the tag.

And step 207, determining a target shooting object corresponding to the label according to the first operation, adjusting the target shooting object by using the target zoom multiple, and displaying the adjusted target shooting object as a preview image.

Furthermore, after a label corresponding to each shooting object in the current scene is displayed on the preview interface, only a first operation of a user for the label needs to be received, zooming can be performed on the corresponding shooting object according to the zooming multiple corresponding to the label, and the zoomed image is displayed on a screen. For example, the first operation may be a click operation, and when the user clicks the "5X" tab at the "person" position in fig. 3, the user may zoom in by 5 times, and the zoomed image preview value is displayed on the screen for the user to observe.

And step 208, receiving a second operation of the user for the label.

And step 209, determining other shooting objects having the same target zoom multiple as the target shooting object according to the second operation, and switching the preview image to other shooting objects.

Further, since the target zoom multiples corresponding to the plurality of objects may be the same or different, for example, the zoom multiples corresponding to the objects closer to the lens are smaller, and the zoom multiples corresponding to the objects farther from the lens are larger, in an embodiment, the objects having the same target zoom multiple in the current scene image may be associated. Specifically, after step 207, preview images of other photographic subjects with the same zoom magnification may be displayed in a switching manner according to a second operation of the user.

For example, the second operation may be a double-click operation, after clicking the label "5X" at the "person" position, the user zooms in the person by 5 times to obtain a preview image, and at this time, the user double-clicks the screen, and may switch to "tree 1" and zooms in the tree 1 by 5 times to obtain the preview image.

As can be seen from the above, the shooting prompting method provided in this embodiment of the present application may receive a shooting instruction, obtain a scene image currently corresponding to a camera according to the shooting instruction, identify multiple shooting objects in the scene image, respectively determine classification information of the multiple shooting objects, determine a preview size corresponding to the classification information, obtain an original size of the shooting object currently in the scene image, calculate target zoom multiple information of the shooting object according to the preview size and the original size, respectively generate tags including the target zoom multiple information corresponding to the shooting object, display the tags at positions of the multiple shooting objects in the scene image as preview images, receive a first operation of a user for the tags, determine a target shooting object corresponding to the tags according to the first operation, adjust the target shooting object by the target zoom multiple, and display the adjusted target shooting object as the preview image, and receiving a second operation of the user for the tag, determining other shooting objects with the same target zoom multiple as the target shooting object according to the second operation, and switching the preview image to other shooting objects. According to the embodiment of the application, the shooting objects in the scene image can be identified, the corresponding target zooming multiple information of each shooting object is calculated, and the user is prompted in a label mode, so that when the user needs zooming shooting, the label is directly selected through operation, and the shooting efficiency is greatly improved.
