Description
本發明涉及具有可變光圈裝置,以控制鏡頭之進光量的行動裝置鏡頭總成。The invention relates to a mobile device lens assembly with a variable aperture device to control the amount of light entering the lens.
已知的智慧型手機大都具有拍照及攝錄影功能,因此愈來愈多消費者已習慣使用手機而不是相機來拍照。在智慧型手機不斷推陳出新的情況下,各主要手機廠商也不斷地主打其手機配備的照相機具有高畫素、大光圈的特點,但很少人知道手機的光圈為恆定的固定光圈,並不能如一般相機鏡頭般地縮小或放大以控制進光量。這是因為受限於行動裝置的輕薄化,使得一般相機常用的光圈馬達及光圈葉片因厚度因素難以直接適用於行動裝置中。Most of the known smart phones have camera and video recording functions. Therefore, more and more consumers have become accustomed to using mobile phones instead of cameras to take pictures. With the continuous innovation of smart phones, major mobile phone manufacturers continue to emphasize that the cameras equipped with their mobile phones have the characteristics of high pixels and large apertures. However, few people know that the aperture of mobile phones is a constant fixed aperture. Generally, the camera lens zooms in or out to control the amount of light. This is because limited by the thinness of mobile devices, it is difficult for the aperture motors and aperture blades commonly used in general cameras to be directly applicable to mobile devices due to thickness factors.
一般照相機控制光圈的縮放是透過光圈馬達來帶動光圈葉片的移動而達成的,但由於手機的體積被要求薄型化且輕量,因此在手機裡配置一顆光圈馬達明顯不可行,況且還有其他的相關光學結構與零組件要配置於手機內,甚至光圈馬達不僅有一定用電量,也要考慮如何散逸馬達及零組件產生的熱能,這些因素加總起來,就必須增加手機內部容置及散熱的空間才能予以解決,但此舉卻違背了智慧型手機輕薄化的設計主流,因此所有智慧型手機都是採用固定光圈,一來讓鏡頭結構更精簡,也可以節省空間供其他零組件配置。Generally, the camera controls the zooming of the aperture through the aperture motor to drive the movement of the aperture blade. However, because the size of the mobile phone is required to be thin and light, it is obviously not feasible to configure an aperture motor in the mobile phone, and there are other The related optical structure and components of the mobile phone must be installed in the mobile phone. Even the aperture motor not only has a certain amount of power consumption, but also considers how to dissipate the heat generated by the motor and components. These factors add up to increase the internal storage and The space for heat dissipation can be solved, but this move violates the mainstream design of thin and light smartphones. Therefore, all smartphones use a fixed aperture, which makes the lens structure more streamlined and saves space for other components. .
除了光圈馬達所佔用的空間大及耗電量相對大的因素之外,另一限制因素是鏡頭的光圈結構,以常見的虹模式光圈為例,虹模式光圈是透過光圈葉片調整光圈之大小,在使用當中按下快門時,光圈自動縮放成使用者在相機介面上所設定的光圈大小;在結構上,光圈葉片是接連堆疊,雖然弧形薄金屬葉片很薄,但還是具有厚度,再加上鏡頭本身的鏡片組合,鏡頭會突出於手機外,容易把鏡頭刮傷,因此一般相機的光圈調整結構無法實現於智慧型手機上。In addition to the large space occupied by the aperture motor and the relatively large power consumption, another limiting factor is the aperture structure of the lens. Take the common rainbow mode aperture as an example, the rainbow mode aperture is adjusted through the aperture blade to adjust the size of the aperture. When the shutter is pressed during use, the aperture automatically zooms to the aperture size set by the user on the camera interface; structurally, the aperture blades are stacked one after another. Although the arc-shaped thin metal blades are very thin, they still have thickness. With the lens combination of the upper lens itself, the lens will protrude out of the mobile phone and it is easy to scratch the lens. Therefore, the aperture adjustment structure of a general camera cannot be realized on a smart phone.
本發明的主要目的在於提供一種具有可變光圈裝置的行動裝置鏡頭總成,其不需要一般相機的光圈葉片及驅動光圈葉片的光圈馬達,並且適合於整合在具有單鏡頭單元或雙鏡頭單元的行動裝置以簡化行動裝置的整體結構。 The main purpose of the present invention is to provide a mobile device lens assembly with a variable aperture device, which does not require the aperture blade of a general camera and an aperture motor for driving the aperture blade, and is suitable for integration in a single lens unit or a dual lens unit.
