Based on the above technical problems, the present application provides a display control method, device, device and medium, which can optimize the preview display effect of the motion state of the moving object during the shooting preview process. The following describes in detail with reference to the accompanying drawings and embodiments.

FIG. 1 is a schematic flowchart of a display control method provided by an embodiment of the present application. As shown in FIG. 1 , the display control method 100 includes step 110 and step 120 .

Step 110: During the shooting preview process, motion information of N moving objects is acquired.

In some embodiments of the present application, the moving object may be different objects such as a person, an animal, a movable object, and the like. In some embodiments of the present application, the motion information of the moving object may include information such as the speed of the moving object, the position of the moving object, and the like.

Step 120: Update the shooting preview screen in the shooting preview interface based on the motion information of the N moving objects.

The N moving objects are objects collected by at least one camera, and N is a positive integer.

In some embodiments of the present application, the shooting preview picture is a picture collected by a camera, and specifically, it may be a shooting preview picture of taking pictures or videos. The shooting preview screen can be used to display the shooting screen of the subject. The shooting preview image of the moving object is the image of the moving object captured by the camera.

In the embodiment of the present application, during the shooting preview process, the shooting preview screen of each moving object in the shooting preview interface is updated based on the motion information of each moving object. The preview shooting picture of the moving object can change with the motion information of the moving object, which can make it easier for the user to preview the moving object clearly, and optimize the preview display effect.

The specific implementation manners of step 110 and step 120 are respectively introduced in detail below.

First, the specific implementation of step 110 is introduced.

In some embodiments of the present application, during the shooting preview process, that is, during the process of collecting a preview image of the shooting scene, at least one camera performs moving object detection on the shooting scene to obtain moving objects in the shooting scene. Then, based on the entire preview image of the shooting scene, the motion information of the moving object can be obtained.

In practical applications, since the preview image of each frame of the shooting scene can represent the state of the object in the shooting scene at a certain moment, if the object in the shooting scene moves, the image of the shooting scene will be obtained with the increase of time. Differences can exist between the preview images in the preview image sequence. Therefore, by comparing the preview images in the preview image sequence, the motion information of each moving object in the shooting scene can be obtained.

In some embodiments of the present application, the motion information of the moving object includes the moving speed of the moving object. For example, for the preview image sequence of the shooting scene obtained within a preset time period, based on the pixel position information of the moving object in each preview image in the preview image sequence, the displacement information of the moving object within the preset time period can be obtained, and then You can get the moving speed of the moving object.

In other embodiments of the present application, the motion information of the moving object may further include relative position information of the moving object and other preview objects in the shooting scene. In some examples, the relative position information of any two moving objects may be determined according to the pixel position information of different moving objects in the preview image of the shooting scene.

In other embodiments, if two cameras are used for shooting, the relative position information between the moving objects can be determined according to the shooting range of each camera. For example, if the first subject is within the shooting range of the first camera, and the second subject is within the shooting range of the second camera, the difference between the shooting range of the first camera and the shooting range of the second camera may be The relative position relationship is obtained to obtain relative position information between the first moving object and the second moving object.

The specific implementation manner of step 120 is described below.

In some embodiments of the present application, each moving object may have a corresponding shooting preview image.

The display control method provided by the embodiment of the present application can be applied to different scenarios, for example, it can be applied to the scene where the total number of moving objects in the shooting preview interface changes, the scene where the speed of the moving objects in the shooting preview interface changes, the shooting preview interface Different scenes such as the scene where the position of the moving object in the interface changes.

When the application scenarios of the display control method provided by the embodiment of the present application are different, the update status of the shooting preview interface is different. In some embodiments of the present application, updating the shooting preview screen in the shooting preview interface includes at least one of the following: updating the number of shooting preview screens in the shooting preview interface; updating the position of the shooting preview screen in the shooting preview interface; updating the shooting preview The area of the shooting preview screen in the interface; update the playback screen in the shooting preview interface.

In some embodiments of the present application, each moving object may have a corresponding shooting preview screen, and in a scene where the total number of moving objects in the shooting preview interface changes, in order to preview the image of each moving object more clearly pictures, the number of shooting preview pictures can be updated accordingly and the area of each shooting preview picture can be updated accordingly.

In some embodiments of the present application, in a scene where the speed of a moving object in the shooting preview interface changes, in order to preview pictures of moving objects with different speeds more clearly, the shooting preview of each moving object can be updated. The area of the picture, and the playback picture is added for the moving objects with high speed, so that the moving objects can be previewed more clearly.

In other embodiments of the present application, if the relative positions of moving objects change in the shooting preview interface, in order to optimize the preview effect of the moving objects, the position of the shooting preview screen of the moving objects in the shooting preview interface can be updated .

In the embodiment of the present application, by updating at least one of the number, area, and position of the shooting preview screen in the shooting preview interface and the playback screen in the shooting preview interface, it is possible to preview the moving object more clearly, to optimize the preview effect.

The specific implementation manner of step 120 will be described in detail below in combination with different application scenarios.

The display control method of the embodiment of the present application can be applied to a scene where the total number of moving objects in the shooting preview interface changes, and the shooting preview in the shooting preview interface is updated based on the information on the change in the total number of moving objects in the shooting preview interface. The number of pictures can make each moving object have its own shooting preview picture, so that the user can preview each moving object clearly, and the preview effect is optimized.

Therefore, in some embodiments of the present application, step 120 includes: in the case that the total number of moving objects in the shooting preview interface changes, based on the change information of the total number of moving objects in the shooting preview interface, update the information on the total number of moving objects in the shooting preview interface. Number of shot preview frames.

In some embodiments of the present application, an object detection method may be used to detect objects in the shooting preview interface, so as to obtain the total number of moving objects in the shooting preview interface.

When it is detected that the total number of moving objects in the shooting preview interface increases by M, that is, M new moving objects are added in the shooting preview interface, then M shooting preview images are added in the shooting preview interface. The newly added M shooting preview images are shooting preview images corresponding to the newly added M moving objects respectively. M is a positive integer.

As an example, referring to FIG. 2 , the shooting range of the camera 20 shown in FIG. 2 includes two moving objects, ie, a moving dog and a moving kitten. Referring to FIG. 3 , the shooting preview interface includes a shooting preview screen 31 of a dog and a shooting preview screen 32 of a kitten.

If a new moving object duckling enters the shooting range in Figure 2, the total number of moving objects in the shooting preview interface increases by 1, and the shooting preview screen of duckling is added in the shooting preview interface to update the shooting preview The number of shot preview images in the interface. Referring to FIG. 4 , the updated shooting preview interface includes three shooting preview screens, namely, a shooting preview screen 41 of a dog, a shooting preview screen 42 of a duck, and a shooting preview screen 43 of a kitten.

When it is detected that the total number of moving objects in the shooting preview interface is reduced by P, that is, P moving objects are reduced in the shooting preview interface, the P shooting preview images are removed from the shooting preview interface. The removed P shooting preview images are the shooting preview images corresponding to the P moving objects that are beyond the shooting range of the at least one camera. P is a positive integer.

As an example, if the puppy in FIG. 4 is beyond the shooting range of the camera 20, the shooting preview image of the puppy is removed from the shooting preview interface, that is, the updated shooting preview interface includes the shooting preview image of the cat and the Duckling's shooting preview.

Therefore, in some embodiments of the present application, step 120 includes: based on the ratio between the moving speeds of the N moving objects, determining the ratio between the areas of the shooting preview images corresponding to the N moving objects; The ratio between the areas of the corresponding shooting preview screen and the total area of the shooting preview interface updates the area of the shooting preview screen corresponding to each moving object.

In the embodiment of the present application, the ratio between the moving speeds of the N moving objects may be determined as the ratio between the areas of the shooting preview images of the N moving objects in the shooting preview interface.

As an example, if there are three moving objects in the shooting preview interface, and the ratio of the motion speeds of the three moving objects is a:b:c, then the area of the shooting preview screen of the three moving objects in the shooting preview interface The ratio is a:b:c. Among them, a, b, and c are all positive numbers.

As an example, referring to FIG. 2 , the shooting range of the camera 20 shown in FIG. 2 includes two moving objects, ie, a moving dog and a moving kitten. Assume that the speed of the puppy is twice that of the kitten, that is, the ratio of the speed of the puppy to the speed of the kitten is 2:1. Then, the ratio of the area of the shooting preview screen of the puppy in the shooting preview interface to the area of the shooting preview screen of the cat in the shooting preview interface is equal to the ratio of the moving speed of the puppy to the moving speed of the kitten, that is, 2:1 . Assuming that the shooting preview interface is displayed on a horizontal screen, see Figure 3, update the area of the shooting preview screen of the dog in the shooting preview interface to 2/3 of the shooting preview screen, and change the area of the shooting preview screen of the cat in the shooting preview screen The area is adjusted to 1/3 of the shooting preview interface.

In the embodiment of the present application, the area of the shooting preview screen between the moving objects is updated according to the speed ratio between the moving objects, so that the moving object with a higher speed can obtain a shooting preview screen with a larger area, thereby optimizing the speed Preview effect for large moving objects.

Based on the above description, it can be seen that when the display control method of the embodiment of the present application is applied to a scene where the total number of moving objects in the shooting preview interface changes, it can not only update information based on the change information based on the total number of moving objects in the shooting preview interface The number of shooting preview images in the shooting preview interface, and the area of the shooting preview image corresponding to each moving object can also be updated according to the ratio between the speeds of N moving objects in the shooting preview image.

Playback screen 62 of the dog. The first preview sub-picture of the puppy is used to keep the preview of the puppy, and the playback picture of the puppy is used to play back the movement of the puppy within a preset time period before the target time. Since the moving speed of the kitten in FIG. 2 does not exceed the first preset motion speed threshold, the shooting preview screen 63 of the kitten may not be updated.

In the embodiment of the present application, if the motion speed of the moving object is greater than the first preset motion speed threshold, the shooting preview picture of the moving object is updated to the first preview sub-picture of the moving object and the playback picture of the moving object, Then, while maintaining the preview of the moving object, the past moving pictures of the moving object can be played back, and the motion state of the moving object can be displayed in more detail, so that the user can preview the moving object more conveniently. And the shooting preview image of the moving object is updated according to the speed of the moving object, which can further save resources.
