With preferable user experience.
Optionally, the method that the application proposes, further includes: after second camera unlatching, examined every the first duration
Whether survey in the primary video image has target object;If not having the target object in the video image, close
First camera or second camera are closed, stopping carries out virtualization processing to the first area.
Specifically, second camera is that have target object post-opening in video image, i.e. the first camera at this time
It is switched on second camera, to realize the virtualization processing of first area, in video process, target object may be short
Appearing in video image repeatedly in time, if continual detection video image in real time, second camera need anti-
Multiple switch, shortens the service life of second camera, and user experience is also bad, therefore, in the present embodiment, takes the photograph at two
In the case where opening simultaneously as head, whether every the first duration, such as every 1 minute, detecting in a video image has mesh
Object is marked, if target object disappears, stopping carries out virtualization processing, and closes any camera, to reduce function
Consumption, prolongs the service life.If this time detection displaying target object appears in video image, examined next time in distance
In the first duration surveyed, even if target object is not present in video image, remains on while opening the first camera and second
Camera, to prevent because switching camera in the short time repeatedly influences service life.Optionally, the first duration can not be short
In 1 minute.In addition, in this application, during being worked by a camera, the first camera and second camera can be with
It works alternatively, for example, what is most started to open is the first camera, after there is target object for the first time, second camera is opened, mesh

The long-pending area ratio with video image is more than the object of the first ratio, for example, it can be set to occupied area is greater than record in video image
As total image area 10% object be target object, or set target object as the object that pixel is more than 300 pixels be mesh
Mark object.Or occupied area account for video image area be more than the first ratio the other object of any sort, for example, it can be set to
In video image, occupied area is greater than the artificial target object of the video image gross area 10%, in actual use, uses
The scene of virtualization video recording is often to shoot the scene of personage, when shooting personage, many times can shoot by other personages,
But the general shared ratio of other personages is smaller, therefore user experience can be improved by the way that the first ratio is arranged.For example, for
When group carries out virtualization video recording, if setting target object is necessarily time-consuming and laborious one by one, therefore, can directly it set at this time
The object that sets the goal is personage, meanwhile, when blurring video recording, because being easy to come in the task shooting of non-targeted object, because
This, setting personage's area and accounting for video image area is more than the personage of the first ratio as target object.To realize fast setting mesh
Object is marked, user time is saved, and avoids asking for shooting effect difference caused by the passerby because of the non-targeted object of unexpected typing
Topic improves user experience, when carrying out virtualization video recording without deliberately avoiding passerby.Preferably, can also be set in take it is non-
When the personage of target object, non-targeted object is replaced according to the image in video image, is taking non-targeted object
Personage when, as previously mentioned, it can be blurred, still, be still easy to find out that it is people from the profile of non-targeted object
Object causes user to record a video when blurring video recording ineffective, therefore, at this time according to the background image being blurred in first area,
