本發明涉及一種相機模組及使用該相機模組的可攜式電子裝置，尤其涉及一種適於自拍的相機模組及使用該相機模組的可攜式電子裝置。The present invention relates to a camera module and a portable electronic device using the same, and more particularly to a camera module suitable for self-timer and a portable electronic device using the same.
隨著多媒體技術的發展，個人數位產品不斷的追求小型化，數位相機、手機等數位產品愈來愈輕薄短小、攜帶方便。為符合目前的多媒體影音傳輸應用，很多個人數位通訊裝置都結合有數位相機之功能。例如，具有照相功能之手機等可攜式電子裝置的市場佔有量日益擴大。With the development of multimedia technology, personal digital products are constantly pursuing miniaturization, and digital products such as digital cameras and mobile phones are becoming lighter, thinner and more portable. In order to comply with current multimedia audio and video transmission applications, many personal digital communication devices combine the functions of digital cameras. For example, the market share of portable electronic devices such as mobile phones with camera functions is increasing.
在習知的多數具有照相功能之手機等可攜式電子裝置中，其相機模組的位置都設置於手機上與其顯示屏相對的背面。採用該等手機拍攝一般景物時，可從顯示屏預覽攝入的影像。然而，當使用者要使用該手機進行「自拍」時，由於相機模組的位置設置於與手機顯示屏相對的背面，故使用者往往只能借助一自拍鏡觀察自身的形貌，而無法透過顯示屏預覽自己將要被攝入相機模組的影像，導致自拍的拍攝效果不佳。In most portable electronic devices such as mobile phones with camera functions, the position of the camera module is set on the back of the mobile phone opposite to its display screen. When shooting a general scene with these mobile phones, the captured image can be previewed from the display. However, when the user wants to use the mobile phone to perform "self-portrait", since the position of the camera module is set on the opposite side of the display screen of the mobile phone, the user often can only observe the appearance of the camera by means of a self-portrait mirror, and cannot pass through. The display previews the image that will be ingested by the camera module, resulting in poor self-portrait shooting.
因此，如何在使用具有相機模組的手機等可攜式電子裝置進行自拍時，仍然能從其顯示屏預覽攝入的影像，為本發明所欲解決的問題。Therefore, how to use a portable electronic device such as a mobile phone with a camera moduleAt the time of shooting, it is still possible to preview the ingested image from its display screen, which is a problem to be solved by the present invention.

In the embodiment, the mirror 24 is at an angle of substantially 45 degrees with respect to the axis of the rotating platform 22. The mirror 24 rotates with the rotating platform 22 as the rotating platform 22 rotates.
該套筒40由一前側壁，一後側壁，一頂壁，一左側壁及一右側壁圍成一大致呈長方體且底部具有一開口41的中空殼體。該前側壁與後側壁分別與頂壁沿圓弧形曲面過渡連接。該前側壁上開設有一第一開孔42，該後側壁上開設有一第二開孔44，該頂壁上開設有一圓孔46。該第一開孔42與第二開孔44中心相互對應。該第一開孔42和第二開孔44內分別裝設有一第一視窗52和一第二視窗54。該第一視窗52和一第二視窗54均採用透明的玻璃或塑膠等材料製成，既可以保護容置於該套筒40內部的元件，也可以讓外部的光線無阻礙地進入套筒40內部。該圓孔46的直徑與旋轉平台22的直徑相當，以將該旋轉平台22可轉動地裝設於該套筒40的圓孔46內。The sleeve 40 is surrounded by a front side wall, a rear side wall, a top wall, a left side wall and a right side wall to form a hollow casing having a substantially rectangular parallelepiped shape and an opening 41 at the bottom. The front side wall and the rear side wall are respectively connected to the top wall along a circular arc-shaped curved surface. A first opening 42 is defined in the front wall, and a second opening 44 is defined in the rear wall. The top wall defines a circular hole 46. The first opening 42 and the center of the second opening 44 correspond to each other. A first window 52 and a second window 54 are respectively disposed in the first opening 42 and the second opening 44.

The fixing base 64 is provided with an image sensor for converting an optical signal into an electrical signal. The holder 64 can be secured to the sleeve 40 by the opening 41 of the sleeve 40.
請參考圖2和圖3，本發明還提供一種使用本發明相機模組10的手機1，該手機1一側設有一顯示屏2。安裝時，該相機模組10鄰近該顯示屏2裝設在其上方，該相機模組10的套筒40的第一開孔42和該手機1的顯示屏2置於手機1的同一側，該套筒40的第二開孔44則置於與該手機1的顯示屏2相反的另一側。該固定座64通過該套筒40的開口41固定在該套筒40上，同時與該顯示屏2及該手機1的內部電路電性連接，用以將其中的影像感測器轉換所得的電信號傳輸至手機1的信號處理部分加以處理，並由該顯示屏2加以顯示。Referring to FIG. 2 and FIG. 3, the present invention further provides a mobile phone 1 using the camera module 10 of the present invention, and a display screen 2 is disposed on one side of the mobile phone 1. When installed, the camera module 10 is mounted above the display screen 2, and the first opening 42 of the sleeve 40 of the camera module 10 and the display screen 2 of the mobile phone 1 are placed on the same side of the mobile phone 1. The second opening 44 of the sleeve 40 is placed on the opposite side of the display screen 2 of the handset 1. The fixing base 64 is fixed on the sleeve 40 through the opening 41 of the sleeve 40, and is electrically connected to the display screen 2 and the internal circuit of the mobile phone 1 for converting the image sensor therein. The signal is transmitted to the signal processing portion of the handset 1 for processing and displayed by the display screen 2.
由組裝方式可以看出，當通過握持該凸緣部221轉動該旋轉平台22時，即可帶動該套筒40內的反射鏡24轉動。當該旋轉平台22的卡塊222轉動到和設於該套筒40上方圓孔46孔壁上的不同凹槽462相嵌合的位置時，該旋轉件20均可固定於該套筒40內，該反射鏡24則可以選擇對準該第一開孔42或第二開孔44。當反射鏡24對準該第一開孔42時，顯示屏2對面的光學影像訊號通過該第一開孔42傳輸至套筒40內部的反射鏡24上，然後被反射至該成像模組60的影像感測器上，轉換為電子影像訊號傳輸到顯示屏2顯示。這樣，不需轉動手機1就可以將與該手機1的顯示屏2相對的影像(例如希望自拍的使用者的形貌)在顯示屏2上加以預覽，方便而準確地實現自拍的目的。當反射鏡24對準該第二開孔44時，手機1背面的光學影像訊號通過該第二開孔44傳輸至反射鏡24上，然後被反射至影像感測器上，轉換為電子影像訊號傳輸到顯示屏2顯示。此時，使用者可以預覽朝向手機1背面(即絕大多數照相手機的正常拍攝取景方向)的影像，從而與使用習知照相手機一樣地對外界進行拍攝。It can be seen from the assembly manner that when the rotating platform 22 is rotated by holding the flange portion 221, the mirror 24 in the sleeve 40 can be driven to rotate. The rotating member 20 can be fixed in the sleeve 40 when the block 222 of the rotating platform 22 is rotated to a position corresponding to the different groove 462 provided on the hole wall of the circular hole 46 above the sleeve 40. The mirror 24 can be selectively aligned with the first opening 42 or the second opening 44. When the mirror 24 is aligned with the first opening 42, the optical image signal opposite to the display screen 2 is transmitted through the first opening 42 to the mirror 24 inside the sleeve 40, and then reflected to the imaging module 60. The image sensor is converted to an electronic image signal for transmission to the display 2 display. ThisIn this way, the image opposite to the display screen 2 of the mobile phone 1 (for example, the appearance of the user who wants to take a self-portrait) can be previewed on the display screen 2 without rotating the mobile phone 1, so that the self-timer can be conveniently and accurately realized. When the mirror 24 is aligned with the second opening 44, the optical image signal on the back of the mobile phone 1 is transmitted to the mirror 24 through the second opening 44, and then reflected to the image sensor to be converted into an electronic image signal. Transfer to display 2 display. At this time, the user can preview the image toward the back of the mobile phone 1 (that is, the normal shooting direction of most camera phones), thereby shooting the outside as well as using a conventional camera phone.
請參考圖4，使用時，該反射鏡24和該第一視窗52、第二視窗54以及該成像模組60互成45度角，這樣顯然可以對正對該第一開孔42或第二開孔44的影像獲得最佳的反射效果。Referring to FIG. 4, in use, the mirror 24 and the first window 52, the second window 54, and the imaging module 60 are at an angle of 45 degrees to each other, so that it is apparent that the first opening 42 or the second opening can be aligned. The image of the aperture 44 provides the best reflection.
在本實施例中，該成像模組60的鏡頭62具有一表面中心點622。若該成像模組60的自身最佳視角為θ，則可根據光路可逆的原理，對應該成像模組60的最佳可見範圍，在反射鏡24上獲得一上反射點244、一下反射點246和一中心反射點242。顯然，該反射鏡24上位於該上反射點244及該下反射點246之間的範圍內的影像位於該成像模組60的最佳視角θ內，可獲得最佳拍攝效果。設該成像模組的鏡頭62的表面中心622到該中心反射點242的距離為H，該成像模組的鏡頭62的表面中心622到該套筒40內壁的距離為D，該第一開孔42和第二開孔44的半徑均為W。則由圖4中不難看出，上述參數之間的數學關係是W=(D+H)tan(θ/2)。在θ大小不變的前提下，D與H之和與W成正比例關係。因此，在實際應用中確保經由該上反射點244及該下反射點246反射的光線均可由該第一開孔42或二開孔44進入或射出該套筒40，以免導致該成像模組60的最佳視角θ內的光路受到阻礙，而造成該相機模組10的最佳拍攝範圍內的影像出現遮蔽及截邊。In this embodiment, the lens 62 of the imaging module 60 has a surface center point 622. If the optimal viewing angle of the imaging module 60 is θ, an upper reflective point 244 and a lower reflective point 246 are obtained on the mirror 24 according to the principle of reversible optical path, corresponding to the optimal visible range of the imaging module 60. And a central reflection point 242. Obviously, the image of the mirror 24 in the range between the upper reflection point 244 and the lower reflection point 246 is located within the optimal viewing angle θ of the imaging module 60, and the best shooting effect can be obtained. The distance from the surface center 622 of the lens 62 of the imaging module to the central reflection point 242 is H, and the distance from the surface center 622 of the lens 62 of the imaging module to the inner wall of the sleeve 40 is D. Both the hole 42 and the second opening 44 have a radius W. It is not difficult to see from Fig. 4 that the mathematical relationship between the above parameters is W = (D + H) tan (θ/2). Under the premise that the θ size is constant, the sum of D and H is proportional to W. Therefore, in practical applications, it is ensured that the light reflected by the upper reflection point 244 and the lower reflection point 246 can be opened by the firstThe hole 42 or the two openings 44 enter or exit the sleeve 40, so as to prevent the optical path in the optimal viewing angle θ of the imaging module 60 from being obstructed, and the image in the optimal shooting range of the camera module 10 is obscured. And cutting edges.
可以理解，本發明提供的相機模組10可以分別對兩個方向進行拍攝取景，且其該旋轉平台22只帶動一反射鏡24轉動，結構簡單且不需要很大的空間，適於安裝在手機1等攜帶型電子裝置上。同時，其成像模組60固定於電路板上，可避免成像模組因旋轉而使其內的電子連接線損壞。本發明提供的手機1不僅能夠方便地實現普通拍攝及自拍功能，而且可以利用該相機模組10兼作電視電話功能所需之專用相訊模組，從而簡化整體結構，減少手機成本。It can be understood that the camera module 10 provided by the present invention can respectively take a picture framing in two directions, and the rotating platform 22 only drives a mirror 24 to rotate, has a simple structure and does not require a large space, and is suitable for being installed on a mobile phone. 1 portable electronic device.
