[Prior Art]
[0002]現有的數位取像模組，包括數位相機、數位攝像機、汽 車的後照取像系統與及時監控系統等，在取像過程中常 常品要較靈活的取像角度。然，現有的取像鏡頭多是相 對取景窗固定，要取像較大視場範圍，相對困難。為擴 大取像視場，現有的技術包括有廣角鏡頭、魚眼鏡頭等 。廣角鏡頭具攝取視場大、誇張變形、擴大透視等特點 。但廣角鏡頭於過近距離攝取景觀時，會出現變形現象 。魚眼鏡頭具有更廣的視場，但是同時魚眼鏡頭也存在 嚴重的畸變形現象。 【發明内容】 r[0002] The existing digital image capturing module, including a digital camera, a digital camera, a rear photographing system of a car, and a timely monitoring system, often have a relatively flexible image capturing angle in the image capturing process. However, the existing image taking lenses are mostly fixed relative to the viewfinder window, and it is relatively difficult to take a larger field of view. In order to expand the field of view, existing technologies include wide-angle lenses and fisheye lenses. The wide-angle lens has the characteristics of large field of view, exaggerated deformation, and enlarged perspective. However, when the wide-angle lens takes over the landscape at a close distance, deformation will occur. The fisheye lens has a wider field of view, but at the same time the fisheye lens also has severe distortion. [Abstract] r

The S-study element 30 can be a glass or plastic lens or lens having good light transmission, the diameter of which is larger than the diameter of the transparent cover 72 of the lens module 7. The rotary platform 3 is formed by plastic injection molding, and a pair of first electrodes 32, 32 are formed on the opposite sides of the lower surface. A pair of second electrodes 76, 76 are provided on the upper surface of the lens barrel 70 with respect to the electrodes 32, 32'. A first voltage and a second are applied between the first electrode 32 and the second electrode 76, between the first electrode 32, and the second electrode 76 via a flexible circuit board FPC or a cable (not shown). Voltage. There is a voltage difference between the first voltage and the second voltage, and the voltage difference drives the rotating platform 3 to rotate about the rotating shaft 5. In order to achieve a better effect of the voltage difference between the first voltage and the second voltage, a control switch can be provided to control the time, frequency, etc. of the rotation of the rotating platform 3, and the rotating platform can be manually rotated as needed. [0008] Of course, the electrodes 76 and 76' may also be replaced by a pair of magnets, and the electrodes 32 and 32' may be replaced by a pair of electromagnets. After the energization, the electromagnet generates a suction or repulsive force on the magnet to drive the rotating platform 3 to rotate. [0009] Referring to the third figure, the digital position of the optical Φ element is not set before the rotation of the preferred embodiment of the present invention. Like the module field of view schematic. The light is imaged on the image detecting component 9 through the lens module 7 to form an image plane 11. The angle between the lens node A and the image plane 11 from the focal length f of the lens is an image angle and an image field angle. The top angle is the field of view angle 0. When the rotary platform 3 is not provided, the range determined by the line a, (the extension of the line 3) and the line b' (the extension of the line b) (i.e., the range indicated by the arrow in the figure) is the field of view. [0010] Please refer to the fourth figure, when the rotating platform 3 is rotated, the position of the lens module 7 and the image detecting component 9 in the embodiment of the present invention does not change, and thus 094121272 1003312682-0 5th/11 Page Form No. A0101 1353777 [0012] [0014] 094121272 The field of view angle 0 determined by the correction replacement page on August 25, 100 is fixed, but the field of view is enlarged. For the convenience of description, take the left half of the view as an example. The incident light from the outside is incident on the lens module 7 through the refraction of the optical element 30, and is then imaged on the image plane u. The line b' is the incident light of the outermost boundary, that is, the line !^, and the incident light on the left side cannot be imaged on the image plane 11. According to the reversibility of the light, it can be assumed that the line b is incident on the optical element 30. After the optical element 30 is rotated by an angle α, the incident angle of the line b also changes. Due to the refraction of the optical element, the outgoing strip bl is opposite to the line b. The optical element 3 has a leftward displacement on the upper surface, and the line bl is parallel to the line b'. The shaded portion in the figure (i.e., the range between the lines b' and bl) is an enlarged field of view. As can be seen, the greater the displacement of the line Μ on the upper surface of the optical element 30, the larger the field of view of the enlarged field of view. The amount of displacement is associated with the thickness and refractive index of the optical element 3〇. Therefore, in order to achieve a better field of view expansion effect, it is possible to control the shape of the optical element 3〇 in addition to an optical element having an appropriate refractive index. The optical element 3G on the rotating platform 3 may have a shape in which one side is thin and thick, or a shape in which the thickness is thin in both sides. In summary, the present invention complies with the requirements of the invention patent, and the Newfa patents apply. However, the above description is only a preferred embodiment of the present invention, and any equivalent modifications or variations made by those who are familiar with the art of the present invention in the spirit of the present invention should be included in the following patents.
