J ... The lens holder 102 is for carrying the lens barrel 104. The barrel 104 is generally cylindrical in shape with a barrel 116 surrounding the entire barrel 104. The inner side 116 of the lens barrel has a first chamber 118 formed in the lens barrel 1〇4, and the chamber U8 is located between the first end and the second end of the lens barrel 104. The M341234 is disposed on the first mirror group 106. The first end (top) of the lens barrel 104 is accommodated in the space, and the first lens group 108 and the third lens group are disposed in the accommodating space 122 of the second end (bottom) of the lens barrel 104. The first mirror group 1〇6 has a negative refractive power-degree and its convex surface faces the object side. The first mirror group 1〇6 is a spherical or aspherical lens, and the reciprocal of the focal length value of the first mirror group is not equal to zero. The electrically controlled zoom device ι 2 is disposed within the first chamber 118 of the side sill 116. Thus, the electronically controlled zoom device 112 is disposed between the first mirror group 1 〇 8 and the second mirror group 1 〇 8. The electronically controlled variable focus device adjusts the radius of curvature of the lens inside it to variably control the effective focal length of the zoom device and provide good optical characteristics. The third mirror group 110 is disposed below the second mirror group 108, and is disposed in the accommodating space 22 at the bottom of the lens barrel 104 together with the second mirror group 108. The image sensor 114 is located at the bottom of the lens holder 1 〇 2 and is used to capture images through the lens set. The image sensor 114 includes a Charge-Coupled Device (CCD) image sensor or a Complementary ❿ Metal-Oxide-Semiconductor (CMOS) Sensor. In the preferred embodiment, electronically controlled zoom device 112 includes an electrically controlled zoom element 124, an electrode 120, and an electrically controlled zoom mount 128. The electrically controlled zoom element 124 is electrically connected to the electrode 126 and is mounted together in the electronically controlled zoom socket 128. The electrode 126 has a flexible printed circuit (FPC) 130 for connecting an external device or member. Referring to FIGS. 2 and 3, the electronically controlled zoom element 124 is made of a first material layer i24a and a first material layer 124b, and is biased to the electronically controlled focusing element 124 according to the bias voltage applied to the transmitting electrode 26 The curvature of the electrically controlled zoom element 124 is ^341234 (CUrMture) 'for the purpose of adjusting the focal length. In the preferred real mud - factory ^ Mai Jiao component can be a liquid lens (liqUid lens). The method of assembling a module having a variable curvature lens is to first place a test lens set into the above-mentioned first cavity to measure or correct to obtain the best back focus value of the 杈 group, and complete the most After the post-focus test, the above-mentioned electric & E-focus device force σ is assembled. The electronically controlled zoom device is disposed in the direction of the lens barrel perpendicular to the optical axis, and is placed in the first chamber of the side wall of the lens barrel, which is different from the method of the old-fashioned operation, and the assembly or/and correction method is repeated. 'To adjust the distance between each lens group, electronically controlled zoom element and image sensor to achieve optimal status. The assembly method of the prior art will waste a lot of assembly, calibration time and cost. The module with variable curvature lens of the present invention arranges the electronically controlled zoom device in the first chamber inside the lens barrel, and no need to change other components in the module. Furthermore, the variable curvature lens structure of the present invention overcomes the deterioration of the image quality of the conventional fixed focal length lens in close-up. The variable curvature lens structure of this creation utilizes the above-mentioned electronic control #隹读币? y tender ice mirror to change the double curvature, the fixed focal length of the fixed-focus lens in the form of a small zoom in the form of a small zoom A > 5f, the effective curvature of the lens of the variable curvature of the furnace Without a bow extension (object distance A = oo), the focal length changes during photography, so that a higher resolution can be achieved than a fixed focal length head. ..... see, this creation also reveals - a model with a variable curvature lens first ★, first provides a lens barrel, inside the barrel defines a first chamber inside, the first chamber The chamber is between the top and bottom of the lens barrel. Then, the first mirror group is disposed to the first receiving space 9 M341234 of the first end of the lens barrel, the year < the object day ~, this ~, and the second mirror group is disposed at the second end of the second end of the lens barrel For example, the first mirror group is a spherical or aspheric lens, and the inverse of the focal length value of the first mirror group is not equal to zero. The third mirror group is sequentially disposed behind the second mirror group according to the direction from the object side to the image measurement. After the first lens group and the second lens group have been assembled to the lens barrel, the lens barrel that has been assembled with the lens group is disposed on the lens holder, and when the lens barrel and the lens group are disposed on the lens holder , the image sensor is disposed below the lens holder. The image sensor may include a charge surface element image sensor or a complementary MOS image sensor. The purpose of the image sensor is to capture images from the external environment. At this time, the lens barrel, the above-mentioned lens group, and the image sensor have been planted to the lens holder to become a semi-finished module, but the various parameters of the module (4) have not been corrected, and the electronically controlled zoom device is not installed. It is installed in the image sensing module. A test mirror is disposed in the first chamber of the inner side wall of the lens barrel, and the parameter of the group is used to obtain the optimal parameter value of the module. After adjusting the mode (4); after paying the optimal parameter value of I, the test mirror is taken out in the first chamber. Then, the first-chamber creation system of the configuration-electronically controlled zoom device on the inner side of the lens barrel has an embedded zoom device in the middle, and even if it is zoomable, it can also have a larger numerical mirror group and the above-mentioned electronically controlled zoom. The device includes an electrically controlled zoom element, an electrode, and an electrically controlled zoom element holder. The electronic control (4), the component and the electrode are electrically connected and disposed in the socket of the electronically controlled zoom component. Brush the board to connect external devices. The electric focus M341234 is supplemented by a l I ^ fo s added to the second material layer to make the curvature of the electronically controlled zoom element according to the voltage passing through the above-mentioned "Gu". The electronically controlled zoom element described above may be a liquid lens. In the preferred embodiment, except that the first mirror is a spherical or aspheric lens, the other mirrors are aspherical lenses. The above mirrors are molded from plastic, glass, quartz, etc. The preferred method is plastic, which reduces the cost of materials compared to glass. Because the first mirror group is first installed in the lens barrel, if we follow the order of common knowledge, along the same optical axis, from the physical measurement to the image measurement, the first:: group, electronically controlled zoom Assembly, second mirror, and third mirror assembly into the lens will create problems. Therefore, when the parameter values of the module (for example, Back Focus Length (BFL)) are to be adjusted, if the above configuration mode is adopted, the optimal back focus value of the module cannot be adjusted because of electronic control. The effective focal length value of the variable member is a range value. If the focal length value of the residual 隹 component is directly adjusted, the entire module cannot obtain the optimal back focus value, and only a valid range value may be obtained. Therefore, the method of configuring or correcting the module having the variable curvature lens of the present invention first uses a test mirror set to measure the optimal back focus value of the module and then put it into the electronically controlled zoom device for assembly. The electronically controlled zoom device is disposed in the direction of the lens barrel perpendicular to the optical axis, and is placed in the first chamber inside the lens barrel, which is different from the conventional technology. This type of mounting method does not need to repeatedly remove the module for adjustment. The distance between each mirror group, the electronically controlled zoom element, and the image sensor is optimal. The above-described assembly method of the prior art wastes a lot of process time and cost. The module with variable curvature lens of this creation is 11 M341234 Λ 11 V ίο:, the electronically controlled zoom device is placed in the first chamber inside the lens barrel (4) and the other components in the module are moved. This will save more time and cost. For those skilled in the art, the present invention is described by a preferred example. However, it is not intended to limit the spirit of the present invention. Modifications and similar configurations made without departing from the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
