[Prior art] The Michichi 'digital camera module is mounted on a wide-range camera. The digital camera module capturing device and an optical lens system are placed at the focal point of the optical lens system, and the terminal device embedded in the digital camera module is used for human. It is widely used in a mobile phone, a PDA, or a computer 'to mount an image on a substrate to a light receiving plane of an image capture device. This module can send the captured image cable or wirelessly to him ^ ^ ^ I hope that the zoom of the lens of the portable terminal that he is holding can be as dry as possible. Digital camera modules that can be zoomed usually use a complex lens configuration = learning lens system. When shooting, the focal length of this system is changed by changing the distance between each lens to achieve the purpose of zooming. Mainland China Patent Application No. 0225 84 95 discloses a lens group for a lens, which is composed of four lenses, which can form a long back focal length and a back focal length that is large enough to ensure that the lens forms an image at the receiver. However, although this design has extended the range of the focal length of the lens, the end-of-line system is limited, and the length and weight of the lens have been increased, which is inconvenient for small terminal equipment. For this reason, it is necessary to provide a digital camera module with a simple structure and no optical focal length limitation. [New content] The purpose of this creation is to provide a digital camera module with a simple structure and no optical focal length limitation.

The light guide plate is provided with a plurality of through-holes; the microlens array includes a lens substrate and a plurality of microlenses arranged on the lens substrate; and the phosphor array includes a plurality of filters. The light guide plate, the micro lens array, and the fishing lens array are sequentially arranged according to the path of light incidence, and the exit of the through hole, the micro lens, and the filter correspond in a two-dimensional space. Compared with the conventional digital camera module, this creation uses a light guide plate with a plurality of through holes and a micro lens array for imaging. The through holes of the light guide plate have different inclination angles, making them have light selection. After the light refracted on the object is selected through the through holes of the light guide plate, it is imaged on the focal plane of the micro lens through the micro lens array. Digital cameras obtain color information through a filter array. This creation replaces the traditional multiple lens imaging, reduces the size of the digital camera module, and can be imaged on the focal plane of the micro lens without adjusting the focal length regardless of the object distance. There is no restriction on the traditional optical focal length. This creation is a flat-type, 'σstructure', which is easy to be modularized with the special components of the shirt image sensor, which is easy to produce and install.

The light guide plate 11 has a certain thickness, and a plurality of narrow through holes lu are provided thereon, and the inclination angles of the through holes 111 are different. Please refer to the second figure in combination. The light guide plate 丨 丨 the through hole 111a on its central axis is perpendicular to the plane on which the light guide plate 丨 丨 is located.

The reverse extension lines of the through holes U1 meet at the convergence point 丨 3 on the central axis, and the overall view is radial. The convergence point 1 丨 3 determines the inclination angle of each through hole 丨 i 丨, and the distance from the light guide plate 11 is not fixed, and can be adjusted as needed. The microlens array 13 includes a lens substrate 131 and a plurality of microlenses 133. The microlenses 1 3 3 are hemispherical, and each microlens 3 3 corresponds to an exit of a through hole 111 in a two-dimensional space and is arranged on the lens substrate 1 3 1. The microlens array 13 can be formed by injection molding or electroforming using a transparent synthetic resin material and utilizing the thermal fluidity of the synthetic resin. A light blocking ring 1 3 5 is arranged around the micro lens 1 3 3 to absorb the diffracted light. The light blocking ring 135 is made of a light-shielding material. In order to better absorb the diffracted light, an opaque layer (not shown) is provided on the surface of the lens substrate 丨 3 1 where no micro lens 丨 3 3 is provided. The filter and light filter array 15 is formed by arranging a plurality of light filters 1 5 1, and each filter 1 5 1 corresponds to a micro lens 3 2 in a two-dimensional space. The filter array 5 includes red, green, and blue primary color filters or cyan, purple, and yellow complementary color filters. The filter 1 51 is arranged in an array corresponding to the arrangement of the microlenses 33 by a plating technique to obtain color information.凊 Combined with reference to the first and third figures, according to the path of light incidence, the digital camera module 10 of this creation is sequentially arranged from the left to the right as a light guide plate i 丨, a microlens array 13 and a filter array 15. Light from different directions is incident on the light guide plate 1 1. Because it is made of a light-shielding material, the light is blocked at the place where no through hole 1 is provided. In the light incident on the through-hole 111, because the light guide plate n has a certain thickness, the incident light at a certain angle with the axis direction of the through-hole 1 1 1 丨 7 1 is the through-hole after entering the through-hole 1 1 1 The inner wall of the hole 1 1 1 is blocked.

M250181 五、創作說明（4) 好吸枚光線之性能，該入射光線1 7 1即被吸收，不再發生反 射或折射。因通孔丨丨1内徑狹小，則可順利通過之入射光線 1 7 3即被視為其入射角度與該通孔丨丨1之傾斜角度一致。 微透鏡陣列1 3緊貼導光板11。經由導光板1丨進行方向 运擇之入射光線173通過通孔111之出口後，即進入微透鏡 1 3 3。微透鏡丨3 3之焦距微小，源自物體之入射光線1 了 3可視 為自然躬遠處射出。根據光學原理，該入射光線丨7 3於微透 鏡133可視為平行之光線，匯聚於微透鏡丨33之焦點。入射 光線1 7 3通過狹小通孔111後必然發生繞射，擋光環1 3 5將高 階繞射光線阻擋並吸收，降低各通孔丨丨1之繞射光線對鄰近 區域產生之影響。 濾光片陣列1 5設置於微透鏡陣列1 3後，每一濾光片} 5 i 對應一微透鏡133。入射光線173經過微透鏡ι33折射後入射 至與該微透鏡1 3 3相對應之濾光片1 5 1，生成色彩訊息。 整體觀之，物體上任意一點所折射之光線經由導光板 1 1之通孔111 iM亍方向選擇後，通過微透鏡丨3 3於其焦點處 成像。則物體成像於微透鏡陣列丨3之焦平面處。數位相機 藉由濾光片陣列1 5獲得色彩訊息。導光板丨1之通孔1丨1數量 及其傾斜角度決定照片之解析度及其像素之位置。單位面 積上通孔ill之數量愈多，照片之解析度愈高；匯聚點113 離導光板11愈近，通孔111之傾斜角度愈大，其發散趨勢愈 明顯。數位相機於後期處理數據時，將藉由軟體插值等方 式提高照片之非中央區域之解析度。 了以理解本創作數位相機模組1 〇可於導光板1 1與微M250181 V. Creative Instructions (4) The performance of the light absorption is good. The incident light 1 1 is absorbed and no reflection or refraction occurs. Due to the narrow inner diameter of the through-hole 丨 1, the incident light 1 3 that can pass through smoothly is regarded as the incident angle consistent with the inclination angle of the through-hole 丨 丨 1. The microlens array 1 3 is in close contact with the light guide plate 11. The incident light 173, which is directionally selected through the light guide plate 1 丨, passes through the exit of the through hole 111 and then enters the microlens 1 3 3. The microlens 丨 3 3 has a small focal length, and the incident light 1 from the object 3 can be regarded as a natural exit from a distance. According to optical principles, the incident light 7 3 can be regarded as parallel light at the micro lens 133 and converges at the focal point of the micro lens 33. The incident light 1 3 will diffract after passing through the narrow through hole 111. The light blocking ring 1 3 5 will block and absorb the higher-order diffracted light, reducing the influence of the diffracted light of each through hole 丨 1 on the adjacent area. After the filter array 15 is disposed on the microlens array 13, each filter} 5 i corresponds to a microlens 133. The incident light 173 is refracted by the microlens ι33 and is incident on a filter 1 51 corresponding to the microlens 1 3 3 to generate a color message. As a whole, the light refracted at any point on the object is selected through the 111 iM 亍 direction of the through hole 111 of the light guide plate 1 and is imaged at its focal point through the micro lens 丨 3 3. The object is imaged at the focal plane of the microlens array 3. Digital cameras obtain color information through the filter array 15. The number of through holes 1 丨 1 of the light guide plate 1 and the inclination angle determine the resolution of the photo and the position of its pixels. The more the number of through holes ill per unit area, the higher the resolution of the photo; the closer the convergence point 113 is to the light guide plate 11, the greater the inclination angle of the through hole 111, the more obvious the divergence trend. When the digital camera processes data later, it will improve the resolution of the non-central area of the photo by software interpolation. In order to understand this creative digital camera module 1 〇 can be used in the light guide plate 1 1 and micro
