Description
Technical field
The utility model relates to a kind of technology relevant to camera head, refers to especially a kind of optical zoom structure being applied on camera head, can, under the situation without mobile optical eyeglass, reach the object of optical zoom with minimum volume.
Background technology
In recent years, along with scientific-technical progress, the camera head of electronization is constantly towards compact and multi-functional future development, be different from traditional camera and cause that by light the chemical change on egative film carrys out document image, the camera head of electronization is to utilize Image Sensor that optical image is converted to electronic data.Except digital camera, video camera, the 3C Products such as most mobile phone, panel computer, PDA also possess the function of taking pictures and make video recording, have and immediately watch editor, the convenient plurality of advantages such as photo of preserving, become the carry-on shooting instrument that is different from traditional camera market.
In above-mentioned various camera head, no matter being the object that general camera or digital camera will reach optical zoom, is all that the focal length that utilizes zoom lens change subject to be imaged on camera head obtains preferably shooting effect.And existing zoom lens is by an aperture, a plurality of optical mirror slip, and one drive the elements such as driver element that optical mirror slip moves forward and backward to form, and its zoom principle is by the front and back position of mobile optical eyeglass, to reach the object of adjusting focal length; Also because optical mirror slip needs mobile space, make zoom lens must occupy sizable volume in design, add the movably design of optical mirror slip on moving structure and driver element comparatively complicated, cost is also quite expensive, and these zoom lens are limited by very large in application.
For example, in the aforementioned 3C Product with camera head, cell-phone camera module, monitor, or even light and thin type digital still camera etc., because being limited to the restriction on volume and weight, substantially the tight shot of simple structure can only be installed, then by the mode of program patch, mathematical computations, reach the object of zoom, but these class methods belong to amplification local image, i.e. so-called " digital zoom ", not optically change focal length, therefore, in " zoom ", can be reduced on the contrary the imaging image quality of camera head.
Above-mentioned " digital zoom " is although can pass through the progress of the Image Sensor technology such as CCD, CMOS, promote image picture element and the imaging image quality esolving degree of camera head, but tight shot effective focal length value is optically fixed value, and imaging picture is with digital computation, still cannot as Zoom optic lens, at same position, take the different object of far and near distance, and the image clearly obtaining; In other words, no matter Image Sensor technology what evolution for another example such as CCD, CMOS, still cannot change the effect that focal length be reached as zoom lens general using optical principle.
In view of this, the present utility model people accumulates research and the practical experience of association area for many years, spy creates a kind of optical zoom structure of camera head lens, and to overcome, known Zoom optic lens volume is excessive, preponderance, causes the defect of using restriction.

For reaching above-mentioned purpose, the optical zoom structure of the utility model camera head lens, comprise the varifocal mirror group that an optical axis along camera head is arranged on camera lens module the place ahead or rear, wherein, described varifocal mirror group at least comprises a liquid lens, and one group of positive and negative electrode being electrically connected with the main frame of camera head, this liquid lens has a curved surface, curvature that can this curved surface of modulation after positive and negative electrode energising, and then change subject and be imaged on the focal length on camera head after by liquid lens, enable under the situation without mobile optical eyeglass, with minimum volume, reach the object of zoom.
By above-mentioned structure, the positive and negative electrode of varifocal mirror group just can change the curvature of liquid lens after energising, therefore can be under the situation without mobile optical eyeglass, change the focal length of camera lens module refraction image, allow user take the different object of far and near distance at same position, originally inaccessiable Zoom effect of camera head is provided, effectively improves space that traditional optical zoom lens need to be flexible and the puzzlement of preponderance.
Below further illustrate the embodiment of each element:
During enforcement, on the main frame of camera head, be at least provided with the control module that a control varifocal mirror group changes the curvature of liquid lens curved surface.This control module is with built-in procedure operation, accept user's steering order, and then produce signal according to instruction, according to signal controlling, towards the voltage/current of the positive and negative electrode of varifocal mirror group, change the optical characteristics of liquid lens, allow liquid lens under the driving of different voltage/currents, change the curvature of curved surface, reach the Zoom effect that user's wish is carried out.
During enforcement, varifocal mirror group is arranged on camera lens module rear, and described varifocal mirror group is further provided with at least one optical lens along optical axis between liquid lens and camera head main frame.
During enforcement, varifocal mirror group is arranged on camera lens module rear, and described varifocal mirror group is further provided with at least one optical lens between liquid lens and camera lens module along optical axis.
During enforcement, varifocal mirror group is arranged on camera lens module the place ahead, and described varifocal mirror group is further provided with at least one optical lens between liquid lens and camera lens module along optical axis.
During enforcement, varifocal mirror group is arranged on camera lens module the place ahead, and described varifocal mirror group is further provided with at least one optical lens along optical axis in liquid lens the place ahead.
Compared to prior art, the utility model utilizes voltage/current just can change the curvature of liquid lens curved surface, and then the focal length of change camera head imaging, can be under the situation without mobile optical eyeglass, with minimum volume, reach the object of optical zoom, the camera lens module that camera head is provided is inaccessiable Zoom effect originally, and solves that known Zoom optic lens volume is excessive, preponderance, cannot be installed in the shortcoming on some camera head.
