The camera of picture is in holding state, and when the moment meeting switching condition, the camera that triggering is wherein in holding state is opened
Open, and if now close current camera immediately and user carries out inverse operation, need opened and closed again to cut
Change operation, close current camera so that the switching transition of camera is more natural after waiting the scheduled time, it is to avoid no
Repeatedly switch with the open and-shut mode between camera.
Reduce the angle of visual field ratio that predetermined threshold is wide-angle camera 210 and ultra wide-angle imaging head 220.For example, at some
In example, the angle of visual field of wide-angle camera 210 is 90 degree, and the angle of visual field of ultra wide-angle imaging head 220 is 120 degree.Reduce predetermined
Threshold value is 3/4, less than 1.
In operation, first turn on wide-angle camera 210, in reduction operation, when scaling is less than 3/4, will be with number
Word zoom reduces to the preview image of wide-angle camera 210, and when scaling is more than 3/4, takes the photograph opening ultra-wide angle
As 220, and then show that the ultra-wide angle cache image of ultra wide-angle imaging head 220 output is preview image, when in the scheduled time, example
As 1s, user's no amplifieroperation, then close wide-angle camera 210.Certainly, reduce predetermined threshold only to schematically illustrate, do not do
Concrete restriction.In other words, when proceeding by reduction operation, when the ratio of reducing be gradually increased to exceed predetermined threshold when, will
Ultra wide-angle imaging head 220 is switched to by wide-angle camera 210.In this example, the ultra wide-angle imaging head 220 after switching will be directly
Naturally it is imaged for optics, and during reducing, is then shown with digital zoom by wide-angle camera 210 first, until switching to
Ultra wide-angle imaging head 220 is with natural optical imagery state.
