The structural schematic diagram of the image collecting device of method, as Figure 2-3, the adjusting method of image collecting device of the embodiment of the present invention
Including step 101 and 102, step 101：When first lens adjacent with the sensitized lithography of image collecting device be planoconvex spotlight or
When plano-concave lens, the curvature of the curved surface of the first lens is adjusted, the focus of the first lens is made to be moved to the direction far from sensitized lithography,
Such as displacement distance L.Step 102：Otherwise, the curvature for adjusting two curved surfaces of the first lens makes the focuses of the first lens to remote
Direction movement from sensitized lithography, such as displacement distance L.Wherein, the sequence of step 101 and step 102 can be interchanged, step
101 and step 102 can also be combined into step and execute, the present embodiment is merely illustrative, not limits.Below with step
101 and step 102 for be introduced.
Step 101：When first lens adjacent with the sensitized lithography of image collecting device are planoconvex spotlight or plano-concave lens
When, the curvature of the curved surface of the first lens is adjusted, the focus of the first lens is made to be moved to the direction far from sensitized lithography.
In one embodiment, image collecting device is set such as can be the camera of camera, video camera or mobile phone
It is standby.Image collecting device generally includes lens group, focusing motor, infrared ray cut glass and sensitized lithography, wherein lens group packet
One or more lens is included, focusing motor can stretch to push away remote by lens group or further, and infrared ray cut glass was used for
Infrared ray is filtered, interference of the infrared ray to camera shooting, sensitized lithography, that is, imaging plane are prevented.In one embodiment of the invention, thoroughly
Mirror is such as can be concave-convex lens, planoconvex spotlight, biconvex lens, meniscus, plano-concave lens, biconcave lens, liquid lens；
Sensitized lithography for example can be CCD (Charge Coupled Device, ccd image sensor) or photosensitive battle array
Row.
In an embodiment of the invention, as shown in figure 3, image collecting device includes sensitized lithography 50, infrared filter
40, the first lens 30 and the second lens 20, the first lens 30 are plano-concave lens, and the second lens 20 are concave-convex lens, wherein first
Lens 30 and the second lens 20 can also be other kinds of lens, and the quantity of the second lens 20 can be one or more,
It is below plano-concave lens with the first lens 30, the second lens 20 are that concave-convex lens is introduced as an example.
In one embodiment, when first lens 30 adjacent with the sensitized lithography 50 of image collecting device are planoconvex spotlight
Or when plano-concave lens, the curvature of the curved surface of the first lens 30 is adjusted, makes the focus of the first lens 30 to far from sensitized lithography 50
Direction displacement distance L.First lens 30 and the second lens 20 can all roll over the light for the camera lens for entering image collecting device
Penetrate, determine that the focus of lens group (including the first lens 30 and second lens) is the first lens 30, i.e., with 50 phase of sensitized lithography
Adjacent lens, so the first lens of the embodiment of the present invention pair 30 are adjusted.
As shown in figure 3, the first lens 30 are plano-concave lens, the first lens 30 include a curved surface 301, if curved surface 301
Radius is r, curvature K, then r=1/K.The focal length f and the relationship of curvature K of curved surface 301 be：F=1/K (n-1), wherein K is song
Rate, n are the refractive index of the first lens 30.Therefore, the curvature K for changing 30 curved surface of the first lens can adjust the focal length f of curved surface.

From L, in image collecting device, the distance of the focus of the 50 to the first lens of sensitized lithography 30 is image collecting device camera lens
Focal length, therefore, the focuses of the first lens 30 just increase Image Acquisition to after the direction displacement distance L far from sensitized lithography 50
The focal length of device camera lens.
And when the first lens 30 are planoconvex spotlight, the first lens 30 also include a curved surface, 30 curved surface of the first lens
The relationship of focal length f and curvature K is f=1/K (n-1), wherein K is curvature, and n is the index of refraction in lens.Accordingly it is also possible to by changing
Become the curvature K of 30 curved surface of the first lens to adjust the focal length f of curved surface.Similarly, by changing the curvature K of 30 curved surface of the first lens,
Make the focus of the first lens 30 to the direction displacement distance L far from sensitized lithography 50, to increase image collecting device camera lens
Focal length.
Step 102：Otherwise, the curvature for adjusting two curved surfaces of the first lens makes the focus of the first lens to far from photosensitive
It moves in the direction of plane.

The curvature in face is respectively K1And K2, the radius of two curved surfaces is respectively r1And r2, then r1=1/K1, r2=1/K2, the first lens 30
Focal length fIt is concave-convexWith r1And r2Relationship be：
Therefore, the focal length of the first lens 30 can be adjusted by changing the curvature of first 30 two curved surfaces of lens, you can
To adjust the focal position of the first lens 30, make the focuses of the first lens 30 to the direction displacement distance L far from sensitized lithography 50,
To increase the focal length of image collecting device camera lens.
In the adjusting method of image collecting device of the embodiment of the present invention, by adjusting the sensitized lithography with image collecting device
The curvature of 50 adjacent 30 curved surfaces of the first lens, and then the focal position of the first lens 30 is adjusted, finally make the first lens 30
Focus increases the coke of image collecting device in this way to the direction displacement distance L of the sensitized lithography 50 far from image collecting device
Away from, and due to not limited by camera lens (lens) moving range, increase the adjustable range of focal length, realize big multi-focal length optical
Zoom, and the thickness without increasing image collecting device.The adjusting method of image collecting device of the embodiment of the present invention improves
The clarity that remote object is taken pictures, realizes that the depth of field is deeper, clearer Image Acquisition.
In one embodiment of the invention, further comprising the steps of：Adjust at least one the second of image collecting device
The curvature of the curved surface of lens makes the focuses of the second lens be moved to the direction far from sensitized lithography, and mobile distance for example can be with
For L, or other values.This step can execute before step 101 or later, can be also performed simultaneously with step 101.This
Step can execute before or after step 102, can be also performed simultaneously with step 102.As shown in figure 3, in this step, image

As the lens focus of harvester.The process for adjusting 20 focal position of the second lens is similar to the first lens 30 are adjusted, and is to adjust
It saves the curvature of 20 one or two curved surface of the second lens, and then adjusts the focal length (i.e. focal position) of the second lens, make second saturating
The focus of mirror 20 is moved to the direction far from sensitized lithography 50, increases the lens focus of image collecting device.When having multiple second
When lens 20, the adjusting sequence of multiple second lens 20 can be arbitrary.By the song for adjusting at least one second lens 20
Rate, the second lens 20 and the first lens 30 coordinate, and further increase the lens focus adjustable range of image collecting device.
In one embodiment, as shown in figure 3, image collecting device includes second lens 20, the second lens 20 are
Concave-convex lens, including first surface 201 and the second curved surface 202.The curvature for adjusting first surface 201, to adjust first surface 201
Focal position, make the focus of first surface 201 to the direction displacement distance A far from sensitized lithography 50.Adjust the second curved surface 202
Curvature make the focus of the second curved surface 202 also to the side far from sensitized lithography 50 to adjust the focal position of the second curved surface 202
It is identical in scenery wide-angle angle of taking pictures in this way to displacement distance A, the depth of field of taking pictures increase (can photograph it is farther away from
From scenery).
