The focal length cache image of burnt photographic head 220 output is preview image.
Electronic installation 1000 such as mobile phone or panel computer, due to the frivolous demand of global design, usual imaging modules body
The long-pending and equal certain size of thickness requires, and therefore cannot adopt the single imaging modules of optical zoom, and carry out mould using digital zoom
Intend optical zoom, digital zoom carries out cutting and carries out interpolation between the pixel of the image of cutting to image, thus produce putting
The big but relatively low image of resolution.
In operation, generally with wide-angle camera 210 for default camera head, output Radix Rumiciss cache image first is as preview graph

Wide-angle camera 210 is closed after the value scheduled time.
When the switching condition judging to meet photographic head, corresponding photographic head will be opened, accordingly take the photograph in the present embodiment
As head is focal length photographic head 220.After switching photographic head, preview image will be changed into the focal length preview graph that focal length photographic head 220 exports
Picture.It is appreciated that in order to reduce power consumption, generally only opening a photographic head being used for imaging, and another be used for taking the photograph of imaging
As head is in holding state, when the moment meeting switching condition, the photographic head that triggering is wherein in holding state is opened, and this
Shi Ruo closes current photographic head immediately and user carries out inverse operation, then need the handover operation being opened and closed again,
Current photographic head is being closed so that the switching transition of photographic head is more natural, it is to avoid different photographic head after waiting the scheduled time
Between open and-shut mode repeatedly switch.
Amplify the angle of visual field ratio that predetermined threshold is wide-angle camera 210 and focal length photographic head 220.For example, show at some
In example, the angle of visual field of wide-angle camera 210 is 90 degree, and the angle of visual field of focal length photographic head 220 is 30 degree.Amplifying predetermined threshold is
3.
In operation, first turn on wide-angle camera 210, in amplifieroperation, when scaling is less than 3, will be with numeral
Zoom is amplified to the preview image of wide-angle camera 210, and when scaling is more than 3, will open focal length photographic head
220, and then show that the focal length cache image of focal length photographic head 220 output is preview image, when in the scheduled time, such as 1s, uses
Family no reduction operation, then close wide-angle camera 210.Certainly, amplify predetermined threshold only to schematically illustrate, do not do concrete limit
System.In other words, when proceeding by amplifieroperation, when magnification ratio be gradually increased to exceed predetermined threshold when, will be by Radix Rumiciss
Photographic head 210 switches to focal length photographic head 220.In this example, the focal length photographic head 220 after switching will be directly that optics is natural
Imaging, and in amplification process, then shown with digital zoom by wide-angle camera 210 first, until switching to focal length photographic head
220 with natural optical imagery state.
So, the switching between wide-angle camera 210 and focal length photographic head 220 can be completed, to realize optical zoom.
