The user can adjust the shooting posture of the target shooting object according to the shooting prompt information, and finally the terminal device can shoot Compose your ideal image.

Referring to FIG. 2 , it shows the second flowchart of the photographing method provided by the embodiment of the present invention.

The photographing method in the embodiment of the present invention specifically includes the following steps:

Step 201: Obtain a reference image that matches the preview image displayed on the shooting preview interface.

The terminal device can obtain the preview image in the shooting preview screen, upload the preview image to the cloud server, and obtain a reference image matching the preview image from the cloud server. In the specific implementation process, the terminal device can also extract image parameters such as image layout information, image shooting object information, and image background from the preview image, upload the extracted image parameters to the cloud server, and obtain from the cloud server to match the uploaded image parameters. reference image.

Step 202: Based on the reference image and the preview image, generate shooting prompt information of the target body part of the target subject in the preview image.

The target body part includes at least one of feet and head. The shooting prompt information may include the prompt information of the head reference position and/or the prompt information of the head orientation, and may also include the prompt information of the foot reference position.

In the case that the target body part includes feet, based on the reference image and the preview image, the prompt information of the reference position of the feet of the target subject in the preview image is determined.

In the case that the target body part includes a head, based on the reference image and the preview image, the prompt information of the head reference position of the target subject in the preview image is determined.

In the specific implementation process, in addition to determining the head reference position prompt information, the head orientation prompt information can also be determined, specifically: based on the reference image and the preview image, determine the target orientation of the head of the target subject in the preview image; Based on the target orientation, the head orientation prompt information is generated.

Two preferred ways of generating head orientation prompt information are as follows:

Method 1: Determine the target reference object based on the target orientation; generate head orientation adjustment information based on the target reference object;

Wherein, the head orientation adjustment information is used to instruct the user to gaze at the target reference object. The method of generating the head orientation adjustment information based on the target reference object can more conspicuously prompt the user to adjust the head orientation.

For example: as shown in Figure 3, the preview image contains a target subject, and the upper left corner of the target subject contains a tree 301, if it is determined that the head orientation of the target subject needs to be adjusted in a direction relative to the upper right of the subject , then the tree 301 can be determined as the target reference object, and the prompt message “Please look up at the tree on the right” 302 is displayed to prompt the user to look at the target reference object so as to guide the target subject’s head to adjust to the target reference object. .

Method 2. Based on the target orientation, generate a head orientation adjustment guide line;

Wherein, the head orientation adjustment guide line is used to guide the user to adjust the head to the direction indicated by the guide line. The guide line may be a solid line or a dotted line that includes an arrow pointing to, and the direction indicated by the guide line is the orientation of the user's head. This method of prompting the user to adjust the direction of the head orientation through the guide line can more accurately prompt the user to adjust the direction of the head orientation. As shown in FIG. 4 , the guide line 401 displayed in the shooting preview interface can instruct the user to adjust the head orientation to the direction indicated by the guide line 401 .

In the specific implementation process, those skilled in the art may choose any one of the above-mentioned ways to generate the head orientation prompt information according to actual needs.

After the reference image is acquired, the number of people contained in the preview image can be identified, and if the number of people is 1, step 202 and subsequent steps are executed. This method is suitable for single-person shooting, and can improve the accuracy of composition adjustment during single-person shooting. Of course, it is also possible not to identify and determine the number of persons in the preview image.

Step 203: On the shooting preview interface, display the prompt information of the head reference position and/or the prompt information of the head orientation.

In the embodiment of the present invention, an example of displaying the head reference position prompt information and the head orientation prompt information simultaneously on the shooting preview interface is used as an example for illustration. As shown in Figure 5, the target subject is a person whose head is marked with a solid circle 501, and the dotted circle 502 displayed at the upper left corner of the preview image is the head reference position prompt information, as shown in the preview image The guide line 503 with a downward arrow is the head orientation prompt information, that is, guides the user to bow his head.

The user can know to adjust the head to the dotted circle when adjusting the composition through the dotted circle 502 in the preview image, and the user can know to adjust the head orientation to the direction indicated by the guide line 503 through the guide line 503 in the preview image. A preferred method is that when the user uses the composition guide for the first time, while the dotted circle 502 and the guide line 503 are displayed in the preview image, a composition adjustment guide prompt is also given to prompt the user to adjust the target object into the dotted circle 502, Adjust the head orientation to the direction indicated by the guide line 503 , so as to guide the user to complete composition adjustment. This method of guiding the user to adjust the composition can facilitate the user to grasp the composition adjustment operation method in a short time, and shorten the time spent on sufficient adjustment.

In Fig. 5, an example of displaying the prompt information of the head reference position and the prompt information of the head orientation in the shooting preview interface at the same time is used as an example. This method of simultaneously displaying the prompt information of the head reference position and the prompt information of the head orientation can make The adjusted layout of the target subject in the shooting preview interface is more reasonable, and the posture is more coordinated. In the specific implementation process, only the prompt information of the head reference position may be displayed, or only the prompt information of the head orientation may be displayed, as shown in Figs. 3 and 4 . Not only that, in addition to displaying the shooting prompt information of the head in the shooting preview interface, the shooting prompt information of the feet can also be displayed at the same time, or only the shooting prompt information of the feet can be displayed.

The method of simultaneously displaying the shooting prompt information of the feet and the shooting prompt information of the head can refer to FIGS. 6 and 7 .

As shown in Fig. 6, a solid circle 601 is used to mark the head of the target subject in the shooting preview interface, and at the same time, a prompt message of the head reference position, that is, a dotted circle 602 is displayed in the shooting preview interface, which is used to indicate that the head is adjusted to the dotted circle The first adjustment guide line 603 at 602 , the prompt information of the reference position of the foot, that is, the dotted circle 604 , and the second adjustment guide line 605 for prompting the user to adjust the foot to the dotted circle 604 .

As shown in FIG. 7 , when the shooting prompt information is displayed in the shooting preview interface, the foot reference position prompt information and the head orientation adjustment prompt information may also be displayed at the same time. Specifically, the display in FIG. 7 includes a guide line 701 for adjusting the head orientation, a prompt message 702 for prompting adjustment of the head orientation according to the guide line "Please look up at the tree on the right", and a prompt message of the reference position of the feet, that is, a dotted circle. 703 and an adjustment guide line 704 for prompting the user to adjust the foot to the dotted circle 703 . This display mode of shooting prompt information can not only adjust the head and feet, but also provide specific adjustment guidance information, which is convenient for users to operate.

Step 204: When the target body part is adjusted to the shooting posture indicated by the shooting prompt information, perform a shooting operation and output the target image.

Step 203 is a specific realization of displaying shooting prompt information on the shooting preview interface. After the shooting prompt information is displayed, the user can make corresponding adjustments to the target body part according to the shooting prompt information. When the target body part is adjusted to the shooting posture indicated by the shooting prompt information, the terminal device can automatically perform the shooting operation to capture the target image, so that the image with the composition can be captured in time; the terminal device can also adjust the target body part to In the case of the shooting posture indicated by the shooting prompt information, a sign indicating the completion of the composition is displayed, through which the user can confirm that the composition is completed and then manually trigger the terminal device to perform the shooting operation.

Accompanying drawing 8 is a schematic diagram of a shooting preview interface displaying a mark of completion of composition. After the user adjusts the head orientation and foot position of the target subject with reference to the shooting prompt information described in FIG. 7 , a composition completion sign 705 is displayed in the shooting preview interface.

It should be noted that if the terminal device does not detect that the target body part is adjusted to the shooting posture indicated by the shooting prompt information within the preset time period after the shooting prompt information is displayed on the shooting preview interface, the shooting prompt information can be cancelled. The display on the interface ends this composition adjustment. This method can avoid the problem of time-consuming image shooting caused by blindly waiting for a long time for the user to adjust the composition.

In the shooting method provided by the embodiment of the present invention, the shooting prompt information of the target body part of the target shooting object is generated and displayed through the preview image and the reference image. The user can adjust the shooting posture of the target shooting object according to the shooting prompt information, and finally the terminal device can shoot Compose your ideal image. In addition, further displaying the head reference position area and head orientation prompt information in the shooting preview interface can make the layout of the adjusted target object in the shooting preview interface more reasonable and the posture more coordinated.
