Embodiment
For the embodiment of the present invention will be solved technical problem, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiments provide a kind of focus adjustment method, for terminal, described terminal is provided with zoom camera, and described terminal is also provided with the distance-measuring device that transmitting and receiving laser signal carries out range measurement;
Described method as shown in Figure 1, comprising:
Step 11, when using described zoom camera to take, controlling described distance-measuring device and measuring the first distance between described zoom camera and subject;
Step 12, the focal length of zoom camera according to described first distance adjustment.
In embodiments of the present invention, because the transmitting and receiving of laser are not by the impact of current light, the first distance between zoom camera and subject can be measured accurately, therefore, regulate the focal length of zoom camera according to the first distance, can exact focus be realized.
Further, by the far and near level of the focal length length recognition image of adjustment, the level effect of finding a view of slr camera can initiatively be simulated, to reach the object expanding the camera depth of field.
When the focal length according to the first distance adjustment zoom camera, preferably, can be undertaken by following two kinds of modes.
< mode one > auto-focusing
Step 12 is specially:
By the focus adjustment of described zoom camera to the first focal length determined according to described first distance.
This pattern is full intelligent mode, and the first distance that the focal length of camera is measured by distance-measurement module is completely to imaging of focusing.Imaging effect can be confirmed by the default setting of terminal.
The distance that existing terminal can realize by measuring is focused automatically, therefore, in embodiments of the present invention, existing any one can be adopted to realize according to the mode of the first distance auto-focusing measured.
Certainly, shooting preview image can also be generated on a terminal screen, wherein can show the position of the subject projected with infrared laser light source; Simultaneously can the first distance in the shooting preview image generated between Dynamic Announce terminal and subject, facilitate user's anticipation and find a view.
In the focus adjustment method that the embodiment of the present invention provides, not only can realize the effect of similar slr camera auto-focusing, can also realize the effect of similar slr camera manual focus, promote Consumer's Experience, specific implementation is as follows.
< mode two > manual focusing
Step 12 is specially:
The first focal length is determined according to described first distance;
Receive described terminal user send for regulating described first focal length to the focus adjustment instruction of the second focal length;
According to described focus adjustment instruction, by the focus adjustment of described zoom camera to described second focal length.
After distance-measuring device measures the first distance, described first distance can be shown in the shooting preview image generated.Now, terminal use, according to the first distance that screen shows, sends the focus adjustment instruction of focusing.Preferably, the mode analog regulation focal length that touch screen terminal user can draw a circle by using gesture on touch screen realizes finding a view focusing; The terminal of non-large-size screen monitors can adopt adjustment volume key+-mode to distance of focusing.
As shown in Figure 2, can presetting when touch screen terminal user is by drawing a circle clockwise at touch screen, being defaulted as increase focal length, when drawing a circle counterclockwise, being defaulted as reduction focal length; Or, by regulate volume key+-mode increase or reduce focal length.
In embodiments of the present invention, preferably, can arrange when user needs to increase focal length, zoom camera is automatically got subject object behind and is focused; When user needs to reduce focal length, the object that zoom camera is got before subject is automatically focused.
In addition, the effect of final imaging is by manually arranging confirmation.
In order to reach the effect that slr camera cannot realize further, the described method that the embodiment of the present invention provides also comprises:
The depth of field of subject is determined according to described first distance;
Be out of focus by the image adjustment be in outside the described depth of field in the shooting preview image of generation.
The depth of field refers to the subject longitudinal separation scope that the imaging that can obtain picture rich in detail at camera or other imager forward positions measures.After focusing completes, can be formed in the scope before and after focus clearly as, this tandem distance range is exactly the depth of field.
In embodiments of the present invention, can the image be in outside the described depth of field in the shooting preview image of generation is adjusted to out of focus by software process, thus it be clear to reach subject, and the effect of other obscure portions of image.
And then can also focus accurately by the will of user, such as user is by drawing a circle to approve certain part in the way selection exact focus preview image of a certain scope on a terminal screen, now terminal can fuzzy fall other parts, reach the effect that slr camera cannot realize.
In addition, when the subject shown in preview image has multiple, the second distance between two subjects can be shown.
Here that second distance can measure respectively according to distance-measurement module and between subject the first distance, in combination with the angle between optical principle determination camera and this two subjects, obtain described second distance, facilitate user's anticipation and find a view, improving Consumer's Experience equally.
Above-mentioned focus adjustment method overall process as shown in Figure 3, comprising:
Step 31, mobile terminal enters camera-enabled;
Step 32, command range measurement module measures the first distance;
Step 33, select whether carry out AI FOCUS, i.e. automatic focusing, is, enters step 34, otherwise enters step 35;
Step 34, the focal length of focusing zoom camera is to the first focal length determined according to the first distance;
Step 35, after determining the first focal length, the focus adjustment instruction of receiving terminal user, and according to this instruction by the focus adjustment of zoom camera to the second focal length;
Step 36, completes focusing imaging, in the shooting preview image generated, show the first distance.
The embodiment of the present invention additionally provides a kind of focal length adjustment device, and for terminal, described terminal is provided with zoom camera, and described terminal is also provided with the distance-measuring device that transmitting and receiving laser signal carries out range measurement;
