Description
本創作係為一種與攝像裝置相關之技術，特別是指一種應用在攝像裝置上的光學變焦構造，能在無需移動光學鏡片的情形下，以最小的體積達成光學變焦之目的。The present invention is a technology related to a camera device, and particularly refers to an optical zoom structure applied to an image pickup device, which can achieve optical zoom with a minimum volume without moving the optical lens.
近年來，隨著科技進步，電子化的攝像裝置不斷地朝向輕薄短小和多功能的方向發展，有別於傳統相機通過光線引起底片上的化學變化來記錄圖像，電子化的攝像裝置是利用影像感測元件把光學影像轉換成電子數據。除了數位相機、攝影機外，大部分的行動電話、平板電腦、PDA等3C產品也具備拍照和錄影功能，具有即時觀看編輯、方便保存照片等諸多優點，成為有別於傳統相機市場的隨身攝像工具。In recent years, with the advancement of science and technology, electronic camera devices are constantly moving toward light, short, and versatile directions. Different from traditional cameras, images are recorded by chemical changes on the film caused by light. Electronic imaging devices are utilized. The image sensing component converts the optical image into electronic data. In addition to digital cameras and cameras, most 3C products such as mobile phones, tablets, and PDAs also have camera and video functions. They have the advantages of instant viewing and editing, convenient photo saving, etc., and become a portable camera tool different from the traditional camera market. .
上述各種攝像裝置中，無論是一般相機或是數位相機要達到光學變焦的目的，皆是利用變焦鏡頭改變被拍攝物成像在攝像裝置上的焦距來獲得較佳的拍攝效果。而習知變焦鏡頭是由一光圈、複數個光學鏡片，以及一驅動光學鏡片前後移動的驅動單元等元件所組成，其變焦原理是藉由移動光學鏡片的前後位置來達到調整焦距的目的；也因為光學鏡片需要移動空間，使變焦鏡頭在設計上必須佔據相當大的體積，再加上可移動的光學鏡片在移動結構和驅動單元上的設計較為複雜，成本亦相當昂貴，使得該等變焦鏡頭在應用上受到了很大的限制。In the above various imaging devices, whether it is a general camera or a digital camera to achieve optical zooming purposes, the zoom lens is used to change the focal length of the subject imaged on the imaging device to obtain a better shooting effect. The conventional zoom lens is composed of an aperture, a plurality of optical lenses, and a driving unit that drives the optical lens to move back and forth. The zooming principle is to adjust the focal length by moving the front and rear positions of the optical lens; Because the optical lens needs to move space, the zoom lens must occupy a considerable volume in design, and the design of the movable optical lens on the moving structure and the driving unit is complicated and the cost is also quite expensive, so that the zoom lens is made. There are significant restrictions on the application.
例如，前述具有攝像裝置的3C產品中，手機攝像模組、監視器，甚至是輕薄型數位相機等等，因受限於體積和重量上的限制，基本上只能安裝簡單結構的定焦鏡頭，然後藉由程式修補、數學計算的方式來 達到變焦的目的，但此類方法屬於放大局部影像，即所謂的「數位變焦」，並非在光學上改變焦距，因此在“變焦”的同時，反而會降低於攝像裝置的成像畫質。For example, in the aforementioned 3C products with camera devices, mobile phone camera modules, monitors, and even thin and light digital cameras, etc., due to limitations in size and weight, basically only a fixed-focus lens with a simple structure can be installed. And then by program patching, mathematical calculations To achieve the purpose of zooming, but such a method is to enlarge the partial image, the so-called "digital zoom", does not optically change the focal length, so in the "zoom", it will reduce the imaging quality of the camera.
上述「數位變焦」雖然能藉由CCD、CMOS等影像感測元件技術的進步，來提升攝像裝置的影像畫素及成像畫質解晰度，但定焦鏡頭在光學上的有效焦距值為固定值，且成像畫面是以數位計算，仍無法像光學變焦鏡頭一樣在同一位置拍攝遠近距離不同之物體，且獲得的清晰的影像；換言之，無論CCD、CMOS等影像感測元件技術再如何演進，仍然無法如同變焦鏡頭一般利用光學原理改變焦距所達成的效果。Although the above-mentioned "digital zoom" can improve the image pixel and image quality resolution of the image pickup device by the advancement of image sensing component technology such as CCD and CMOS, the optical effective focal length value of the fixed focus lens is fixed. Value, and the image is calculated in digital position. It is still impossible to capture objects with different distances at the same position as the optical zoom lens, and obtain clear images; in other words, no matter how the image sensing device technology such as CCD and CMOS evolves, Still can't use the optical principle to change the focal length as the zoom lens generally achieves.
有鑑於此，本創作人乃累積多年相關領域的研究以及實務經驗，特創作出一種攝像裝置鏡頭之光學變焦構造，以克服習知光學變焦鏡頭體積過大、重量過重，造成使用限制的缺失。In view of this, the creator has accumulated many years of research and practical experience in related fields, and created an optical zoom structure of a camera lens to overcome the excessive size and weight of the conventional optical zoom lens, resulting in the lack of use restrictions.
