Abstract
The invention provides a method of zooming smart camera equipment with one hand by use of action recognition. In view of the problem that a portable camera or a smart mobile device integrated camera controlled by a touch screen can be hardly zoomed with one hand, a built-in accelerometer is used to identify specific fast movements along the lens direction to realize one-hand zooming operation under the condition of no additional hardware devices. The method has the following advantages: the method is completely based on the existing hardware condition, and the device cost is not increased; and one-hand zooming operation is very easy, and the zooming effect is consistent with the direction and degree of change in shooting range caused by camera movement and accords with the intuitive feel of people.
Description
Technical field
The present invention relates to a kind of method of the intelligent capture apparatus zoom controlling such as smart mobile phone, digital camera etc.
Background technology
Portable in order to accomplish, present Portable camera and Intelligent mobile equipment all employ overall touch-screen as uniquely defeated
Enter control device, zoom operation is usually used to " multiple point touching " to realize." multiple point touching " is opened using thumb and forefinger
Or reduce input instruction, and easy to operate, meet human body direct feel.But when needing single-hand held camera and finding a view, " multiple spot
Touch " just become to be difficult to operate.
The method of other one-handed performance camera needs to add other control devices outside touch-screen, such as roller bearing and shaking
Bar.A kind of intelligent control method is also had to be to carry out Face datection using the front-facing camera of intelligent terminal to operator, according to inspection
Survey result and determine that the change of facial size in intelligent terminal moving process controls the zoom magnification of the camera of intelligent terminal, simplify
Zoom operation.
" multiple point touching " operating difficulties in single-hand held camera and when finding a view.The control device such as roller bearing and rocking bar needs extra
Operations area, increased volume weight, is unfavorable for portability.Using front-facing camera for single-lens camera and intelligent terminal
For increased cost.
Content of the invention
The purpose of the present invention is to realize one-handed performance intelligence capture apparatus to realize zoom.
In order to achieve the above object, the technical scheme is that and provide one kind using action recognition come one-handed performance intelligence
The method of energy capture apparatus zoom, described intelligent capture apparatus at least include acceleration transducer, control unit and image unit,
It is characterized in that, comprise the following steps：
When user carries out normal photographing using intelligent capture apparatus and finds a view, the output quantity of acceleration transducer is maintained at one
In the threshold range of individual setting；
When user quickly moves along the camera lens pointing direction of image unit to subject, acceleration transducer defeated
Output exceeds the threshold range setting, and judges intelligent capture apparatus to quilt from control unit according to the output quantity of acceleration transducer
Shoot object place direction to move, thus controlling image unit to amplify zoom；
When user is rapidly directed away from subject along the camera lens pointing direction of image unit, the output of acceleration transducer
Amount beyond the threshold range setting, from control unit according to the output quantity of acceleration transducer judge intelligent capture apparatus to away from
Subject place direction is moved, thus controlling image unit to reduce zoom.
Preferably, described intelligent capture apparatus also include display screen, amplified by display screen preview become defocused image and/
Or reduce the image becoming defocused.
Preferably, amplify the viewfinder range of preview on described display screen causing to diminish and described intelligent capture apparatus shifting
The dynamic degree that diminishes causing is identical；Reduce the viewfinder range of preview on described display screen causing and become big and described intelligence shooting
The big degree of change that equipment movement causes is identical.
The invention has the advantages that：It is based entirely on current hardware condition, the cost of equipment will not be increased；Singlehanded zoom
It is easy to operate, and the viewfinder range change direction that zoom zooming effect causes with camera movement is consistent with degree, meets people
Direct feel.
Specific embodiment
For making the present invention become apparent, hereby it is described in detail below with preferred embodiment.
The a kind of of present invention offer is directed at present come the method for one-handed performance intelligence capture apparatus zoom using action recognition
The Portable camera being controlled using touch-screen and Intelligent mobile equipment are integrated the very difficult one hand of camera and are completed this problem of zoom, not
Under conditions of adding hardware equipment, identify that specific sensing along camera lens quickly is moved in fact using built-in acceleration transducer
Existing singlehanded zoom operation.
, the present invention specifically includes following steps taking the camera with acceleration transducer, control unit and display screen as a example：
When user carries out normal photographing using camera and finds a view, the output quantity of acceleration transducer is maintained at a setting
In threshold range.
When user quickly moves along the camera lens pointing direction of image unit to subject, acceleration transducer defeated
Output exceeds the threshold range setting, and judges camera to subject from control unit according to the output quantity of acceleration transducer
Place direction is moved, thus controlling image unit to amplify zoom.
User can amplify, by display screen preview, the image becoming defocused, amplifies the model of finding a view of the preview on a display screen causing
Enclose diminish identical with the degree that diminishes that causes of camera movement.
When user is rapidly directed away from subject along the camera lens pointing direction of image unit, the output of acceleration transducer
Amount, beyond the threshold range setting, judges camera to away from subject from control unit according to the output quantity of acceleration transducer
Body place direction is moved, thus controlling image unit to reduce zoom.
User can reduce, by display screen preview, the image becoming defocused, reduces the model of finding a view of the preview on a display screen causing
Enclose change greatly and the mobile big degree of change causing of camera is identical.
Claims (3)
