All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The photographing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 shows a flowchart of a photographing method according to an embodiment of the present application, which is applied to a photographing apparatus including a first camera and a second camera, wherein a field angle of the second camera covers and is larger than a field angle of the first camera.
The present embodiment adopts the double-shot photographing mode. The field angle of the second camera covers and is larger than that of the first camera, and the second camera can be used for collecting images in a wider range; the first camera can be used for collecting clearer images.
Correspondingly, the photographing method comprises the following steps:
step S1: and in the process that the first camera exposes the target image, acquiring a first image through the second camera.
In an application scene, for example, in the long exposure mode, a user photographing input is received, and a process of exposing a target image is entered in response to the photographing input. In this process, an image acquired by the second camera, i.e., the first image, is acquired.
The photographing input comprises touch input and space input performed by a user on a screen, and is not limited to input of clicking, sliding and the like; the photographing input also comprises the input of a user on the device for the entity key, and is not limited to the input of pressing and the like; the photographing input also includes input of interaction between devices. Further, the photographing input includes one or more inputs, wherein the plurality of inputs may be continuous or intermittent.
For example, the user presses a photographing key in the night scene photographing mode.
Alternatively, the first camera may have a relatively small field of view, and may be used as a main camera for image capture, and the second camera may have a relatively large field of view, and may be used as a sub-camera for live view in the background.
Correspondingly, the shooting preview interface displays the image collected by the first camera, and the image can be used as a shooting target image and corresponds to a shooting area. The first image collected by the second camera can be obtained from the background but not displayed.
Further, the target image is collected by the first camera, and then the first camera exposes the target image in the exposure process.
Step S2: and when a target moving object exists in the target area of the first image, pausing the process of exposing the target image by the first camera.
The target area is an area corresponding to the non-overlapped field angles of the first camera and the second camera.
In this step, the angle of view of the second camera covers and is larger than the angle of view of the first camera, and therefore, a partial region between the first image and the target image is not overlapped, that is, the target region in this step.
In the prior art, if a photographing input is received, exposure photographing is directly performed. Unlike the prior art, in the embodiment, if a photographing input is received, whether a target moving object exists in the target area is detected, so as to detect whether a moving person or object exists and is strayed into the photographing area.
In the present embodiment, the object of detecting the target moving object is to check whether a person or an object is about to enter the photographing region.
It should be noted that, in order to solve the problem of the smear phenomenon caused by someone or an object straying into the photographing region during the photographing process, the detection can be performed before the person or the object is in the target region, that is, enters the photographing region, so as to avoid the problem that it is impossible to distinguish between the two situations that the moving person or the object strays into the photographing region or the moving object moves when directly detecting whether there is a moving object in the photographing region. In more embodiments, in order to avoid the occurrence of the smear phenomenon, it is also possible to detect whether there is a moving object in the photographing region, and to perform photographing after the moving object remains still or leaves the photographing region.
In this embodiment, if there is a target moving object in the target area, the target moving object may be about to enter the photographing area, and thus exposure photographing is suspended.
Therefore, the method is applied to a long-exposure photographing scene, and if a moving object is about to appear in a photographing area, the exposure photographing action can be delayed.
In this way, in the embodiment of the present application, during the process of exposing the target image collected by the first camera, the first image collected by the second camera is simultaneously acquired. By utilizing the difference of the field angles between the two camera lenses, whether a target moving object exists or not is detected in a target area corresponding to the non-overlapped field angles of the first camera and the second camera in the exposable process, so that the aim of detecting whether the target moving object enters the corresponding area of the target image in advance can be fulfilled. If a target moving object exists in the target area, the target moving object may be about to enter the target image, thereby halting the exposure process. It is thus clear that this embodiment utilizes the angle of view difference that exists between two camera lenses, can perceive the people or the thing mistake of motion to go into the regional phenomenon of shooing in advance to in time pause exposure, thereby solve the user and when utilizing the long exposure function of shooing, in the in-process of shooing equipment shooing, often can meet other people or thing and get into the region of shooing, thereby lead to the problem of the smear phenomenon to appear in the photo, improve one slice rate.
Optionally, the first camera is a tele camera and the second camera is a wide camera.
And under the long exposure photographing mode, simultaneously starting the long-focus camera and the wide-angle camera. The long-focus camera is used as a main camera to shoot images, and the wide-angle camera is used as a secondary camera to conduct background real-time framing. And when the photographing input is received, calculating the field angle difference area between the wide-angle camera and the tele-camera.
Referring to fig. 2, a photographing area 1 corresponding to a target image photographed by a telephoto camera and a field angle difference area of a wide camera and the telephoto camera, i.e., a target area 2 are shown.
Alternatively, the application scenario of the long exposure photographing mode, for example, the user enters a specific mode such as night scene, starry sky, moon, etc., in which the system increases the exposure time for photographing, thereby increasing the brightness of the picture. In another example, the user enters the professional mode, and the exposure time is manually changed, so that the brightness of the picture is improved.
In this embodiment, the problem that when a user takes a picture by using a long-exposure shooting function, other people or objects often enter a shooting area in the shooting process of the shooting equipment, so that the phenomenon of smear of the picture occurs is solved, and the filming rate is improved by utilizing the field angle difference between the telephoto camera and the wide-angle camera and detecting the moving object in the field angle difference area.
In the flow of the photographing method according to another embodiment of the present application, step S2 includes:
step A1: when a target moving object exists in a target area of the first image, if the target moving object moves towards the first area, the process of exposing the target image by the first camera is suspended.
The first area is an area corresponding to the field angle of the first camera.
Optionally, when the target moving object exists in the target area of the first image, the moving line of the target moving object is acquired. And judging whether the target moving object moves towards the first area or not according to the acquired moving line.
The first region corresponds to the target image, i.e., the photographing region.
In the present embodiment, when a target moving object exists in the target area, it is possible to detect whether the target moving object moves toward the first area. When the target moving object moves towards the first area, indicating that the target moving object is about to enter the first area, the exposure photographing is suspended.
In this embodiment, whether the target moving object is about to enter the first area may be determined by determining whether the target moving object moves towards the first area, and when the target moving object moves towards the first area, it is determined that the target moving object is about to enter the first area, and the exposure is suspended, so as to avoid a phenomenon of smear occurring in a picture due to a moving person or object mistakenly entering the photographing area.
In the flow of the photographing method according to another embodiment of the present application, after the step a1, the method further includes:
step B1: when a target moving object exists in the target area of the first image, if the target moving object moves away from the first area, the first camera continues to expose the target image to generate a target image.
Optionally, when the target moving object exists in the target area of the first image, the moving line of the target moving object is acquired. And judging whether the target moving object moves away from the first area or not according to the acquired moving line.
In this embodiment, when the target moving object exists in the target area, it is possible to detect whether the target moving object moves away from the first area. When the target moving object moves away from the first area, the exposure photographing is continued, wherein the target moving object is indicated to leave and enter the first area.
Alternatively, in the case where the target moving object is detected to move toward the first area on one side of the first area, if the target moving object is detected on the opposite side of the first area later, the target moving object is determined to have left the first area by default.
For example, if the target moving object is detected to move toward the first area on the left side of the target image and then the target moving object is detected to the right side of the first area, the target moving object has left the first area by default.
As another example, if the target moving object is detected on the upper side of the first area and then the target moving object is detected on the lower side of the first area, the target moving object is detected as having left the first area by default.
Referring to fig. 3 and 4, it is referable that the target moving object 3 has left the first area 1 by default if the target moving object 3 is detected to move close to the first area 1 on the left side of the first area (photographing area) 1 and then the target moving object 3 is detected to the right side of the first area 1.
It should be noted that, in fig. 2 to fig. 4, the first area 1 is a displayable area in the screen, and the target area 2 is an area that is not displayed, and the target area 2 is shown in the figures and is only used to help understanding the embodiment of the present application.
In this embodiment, whether the target moving object has left the first area may be determined by determining whether the target moving object moves away from the first area, and when the target moving object moves away from the first area, determining that the target moving object has left the first area, and continuing exposure, so as to avoid a smear phenomenon in a picture caused by a moving person or object mistakenly entering the photographing area.
In the flow of the photographing method according to another embodiment of the present application, step a1 includes:
step C1: and if the target moving object moves towards the first area until the distance from the target moving object to the first area is less than or equal to the first distance, pausing the process of exposing the target image by the first camera.
In this embodiment, the condition for suspending exposure is further defined by presetting the first distance, so that the process of exposing the target image by the first camera is suspended only when the target moving object is close enough to the first area. Therefore, when the target moving object is located in the target area and is far away from the first area, the probability of entering the first area is low, exposure and photographing can be continued, and the phenomenon of smearing of the picture cannot occur.
In a flow of a photographing method according to another embodiment of the present application, the method further includes:
step D1: and if the target moving object stops moving and keeps still in the target area, continuing to expose the target image through the first camera to generate the target image.
In this embodiment, if the target moving object stays in the target area and remains still, the target moving object does not enter the first area, the exposure and the photographing can be continued, and the image does not have a smear phenomenon.
In the photographing method according to another embodiment of the present application, the target moving object stays in the first area and remains still, and in this case, there is no moving object in the first area, so that exposure photographing can be continued, and the image does not have a smear phenomenon.
In the flow of the photographing method according to another embodiment of the present application, after step S2, the method further includes:
step E1: and exposing the target image through the first camera after the preset time length so as to generate the target image.
In this embodiment, a preset duration can be set, which is convenient for completing photographing. The application scenes are as follows: the random person or object enters and does not leave the first area within the preset time length, the random person or object does not enter the target area within the preset time length, and the like, and whether the random person or object is static or not, in order to finish the photographing, the photographing can be forcibly finished.
In summary, in the long exposure process, if a moving person or object suddenly enters the photographing region, whether the moving object enters the photographing region or not can be detected in real time in advance, so that the abnormal conditions of the photos such as the smear and the like caused by the fact that the moving person or object mistakenly enters the photographing region are avoided.
It should be noted that, in the photographing method provided in the embodiment of the present application, the execution main body may be a photographing device, or a control module used for executing the photographing method in the photographing device. In the embodiment of the present application, a photographing apparatus is taken as an example to execute a photographing method, and the apparatus of the photographing method provided in the embodiment of the present application is described.
