Frequently, the visual experience of user can be greatly promoted.
In an alternative embodiment, described to obtain the first instruction, comprising: to detect the movement shape of the reference object
State meets the presentation ratio of moving condition, the reference object in shooting picture and meets ratio condition, and/or have for described
In the case where the appearance of the object of reference object, it is full to determine that the reference object local environment and/or the reference object occur
Sufficient specified conditions variation generates first instruction.The reference object can be image or the targeted object of video acquisition,
Such as vehicle, personage, plant, building.If during reference object is kept in motion, needing to detect the speed of service, base
Unexpected deceleration is detected in the speed of service, then is considered as and meets specific moving condition, generates the first instruction.Also such as, to shooting pair
As the presentation ratio in shooting picture is calculated, when calculating the smaller such as less than threshold value of presentation ratio, determination meets ratio
Condition generates the first instruction.For another example, sense in front of reference object object occur by sensor, specifically proximity sensor
When such as barrier, determines that local environment meets specified conditions variation, generate the first instruction.In this optinal plan, based on bat
It takes the photograph object local environment and whether reference object itself meets the first instruction of variation generation of specified conditions.And it is based on first
The switching of different target acquisition device or same target acquisition device difference acquisition parameters is realized in instruction, and then realizes shooting ginseng
Several automatic switchovers are not necessarily to manual switching, greatly save manpower, also highlighted functional diversity.
In an alternative embodiment, described after the progress multi-medium data acquisition using the second acquisition parameters
Method further include: the second instruction of detection, second instruction are characterized as the switching command of acquisition parameters；The second instruction of response, cuts
Changing the second acquisition parameters is the first acquisition parameters, to continue to carry out the acquisition of multi-medium data using the first acquisition parameters.Originally may be used
It selects in scheme, after the acquisition for carrying out multi-medium data using the second acquisition parameters, the second instruction of detection, response second refers to
It enables, then acquisition parameters return the first acquisition parameters from the second shooting parameter switching and carry out continuing to shoot.Wherein, reference object can be based on
Presentation ratio in shooting picture of unexpected speedup, reference object become larger, and/or situations such as obstacle thing's vanished, generate
Second instruction.Realize flexible switching of the acquisition parameters between different values.Flexibly switched according to practical situations,
Enable the acquisition parameters used to be matched with practical situations, avoids the unnecessary waste of parameter resource.
It is described in further detail below with reference to several concrete application scene embodiment of the present invention.
Application scenarios one:
For being applied to vehicle, scene of bringing to a halt as shown in Figure 4:
It is assumed that a camera is installed on vehicle, the camera tool resolution ratio different there are two types of height: 1920 ×
1080 and 1024 × 720 pixel/inch.In the normal driving process of vehicle, the control device of the embodiment of the present application is installed
Vehicle detection running velocity, the speed of service is detected particular by sensor, if the speed of service is preset normal
It is worth in range, then it is assumed that be normally travel, trigger the starting of camera, make it using low resolution to the traveling in road ahead
Environment is shot.Once front occur barrier such as pass through proximity sensor detect front there is barrier such as dog, or
Since front vehicles are slowed down or Uneven road more jolts that this vehicle is caused to be also required to slow down suddenly suddenly, sensor,
Specifically velocity sensor detects that the speed of service declines suddenly from range of normal value, it is determined that the road environment of vehicle becomes
Change, generates the instruction of acquisition parameters switching.It is high-resolution that control device, which switches the resolution ratio of the camera by low resolution, is led to
Cross the shooting that high-resolution carries out running environment.
It can also be with there are two cameras for installation on vehicle, and one of camera is normal camera such as 270 ° of wide-angles, separately
One camera is wide-angle camera such as 360 ° of wide-angles.In normal vehicle operation, default is travelled using normal camera
The acquisition of environment.In the case where vehicle is brought to a halt suddenly, wide-angle camera is switched to, using wide-angle camera to traveling
Environment is acquired, and the image and/or video of wider wide-angle can be obtained.
This appearance according to the speed of service or barrier carries out the switching of same acquisition device difference acquisition parameters automatically
Or the switching of different acquisition device, it can avoid being manually operated and bring is inconvenient, humanized behaviour provided for vehicle
Make, also the confirmation of responsibility for the retention of subsequent image or traffic accident provides relatively sharp and/or broader wide-angle video or image.
It can greatly enhance the user experience.
Under this application scene, it can such as be examined by sensor in the case where unexpected the case where slowing down disappearing a period of time
Measure speed be gradually recovered normal value and maintain normal value for a period of time when, then the resolution ratio of camera is switched back into low resolution
Rate, or camera is switched back into normal camera from wide-angle camera, in the case where normally travel using low resolution or
The image definition or wide angular range taken using normal camera is enough, takes the photograph without high-resolution or using wide-angle
As head, and then it can avoid shooting due to the high-resolution using same camera or caused by using wide-angle camera, deposit
The problem of wastings of resources such as storage.
Application scenarios two:
For being applied to mobile phone:

1080 and 1024 × 720 pixel/inch.The mobile phone for being equipped with the control device of the embodiment of the present application detects starting camera
When instruction, camera carries out the acquisition of image using the resolution ratio such as low resolution of default.It is assumed that being by what the mobile phone acquired
Reference object A participates in the picture of football match on court.For the acquisition of the picture, control device calculates reference object in real time
Presentation ratio of the A in shooting picture switches camera from low resolution if calculated ratio is less than threshold value 50%
To high-resolution, continue the acquisition of reference object A match picture using high-resolution.
It is assumed that there are two cameras for tool on mobile phone, one is normal camera, the other is wide-angle camera (wide-angle imaging
The wide-angle of head is greater than normal camera), foregoing scene, if presentation ratio of the reference object A in shooting picture is small
In threshold value 50%, camera can also be switched to wide-angle camera from normal camera, carry out wider angle using wide-angle camera
The acquisition of degree, so that reference object A is more highlighted in the picture of shooting.
This presentation ratio according to reference object in shooting picture carries out same acquisition device difference shooting ginseng automatically
The switching of several switching or different acquisition device, can avoid manual operation and bring is inconvenient, and providing for mobile phone is more people
The operation of property, also greatly enhances the user experience.
Under this application scene, presentation ratio of the reference object A in shooting picture is calculated in real time, once discovery presentation ratio
There are ascendant trends, then the resolution ratio of camera can be switched back into low resolution, or camera is switched from wide-angle camera
Normal camera is returned, can avoid clapping due to the high-resolution using camera or using image caused by wide-angle camera
The wastings of resources the problem of such as take the photograph, store.
