Description
本發明係關於一種攝影裝置,特別是一種具有廣角鏡頭的攝影裝置。 The present invention relates to a photographing apparatus, and more particularly to a photographing apparatus having a wide-angle lens.
一般來說,監視攝影機用途十分廣泛,舉凡安裝在工廠廠房、宿舍、商店、大樓或社區住宅出入口、通道等需監視的場合或人跡罕至之隱密處,均可藉由監視攝影機即時錄下當時狀況,以供日後追查、存證等用途。藉此可嚇阻不肖份子進行不法行為,進而避免危害治安的事情發生。 In general, surveillance cameras are widely used. Any occasions that need to be monitored in factory buildings, dormitories, shops, buildings or community homes, entrances and exits, or inaccessible places can be recorded immediately by surveillance cameras. For later use in tracing, depositing and other purposes. In this way, it can deter unscrupulous behaviors and avoid the harm of law and order.
為了減少監視攝影機監視的死角,廠商紛紛推出具有較大監視範圍的魚眼監視攝影機。雖然魚眼監視攝影機的監視範圍較大,但在夜間或者光源不足的情況下監視時,魚眼監視攝影機常會受限於內部配置之紅外線光源的照射角度與強度,使得魚眼監視攝影機無法正常發揮監視功能或需額外借助外部照明設備才能夠正常發揮監視功能。舉例來說,以目前市面上常見的魚眼監視攝影機的視角可達170度以上,而其內部配置之紅外線光源的投射角度只能達到90~100度,無法涵蓋整個魚眼監視攝影機的視角,因此會造成監視攝影機所拍攝的影像之中心光源照度足夠,而影像外 圍偏暗此俗稱為手電筒效應的問題。 In order to reduce the dead angle of surveillance camera surveillance, manufacturers have launched fisheye surveillance cameras with a large surveillance range. Although the surveillance range of the fisheye surveillance camera is large, when monitoring at night or when the light source is insufficient, the fisheye surveillance camera is often limited by the illumination angle and intensity of the internally arranged infrared light source, so that the fisheye surveillance camera cannot function properly. Monitoring functions or additional external lighting are required for proper monitoring. For example, the angle of view of a fisheye surveillance camera that is commonly available on the market can reach 170 degrees or more, and the projection angle of the infrared light source configured therein can only reach 90 to 100 degrees, and cannot cover the angle of view of the entire fisheye surveillance camera. Therefore, the center light source of the image captured by the surveillance camera is sufficient, and the image is outside the image. This is commonly known as the problem of flashlight effect.
本發明在於提供一種攝影裝置,藉以解決在夜間或者光源不足的情況下監視時,魚眼監視攝影機常會受限於內部配置之紅外線光源之照射角度與強度,使得魚眼監視攝影機無法正常發揮監視功能或需額外借助外部照明設備才能夠正常發揮監視功能的問題。 The invention provides a photographing device, which can solve the problem that when the nighttime or the light source is insufficient, the fisheye surveillance camera is often limited by the illumination angle and intensity of the internally arranged infrared light source, so that the fisheye surveillance camera cannot function normally.

The imaging angle of the wide-angle lens module 200 is, for example, 170 degrees, but is not limited thereto. In this embodiment, the wide-angle lens module 200 is a fisheye lens and is used to monitor objects in the range of 1 meter to 5 meters.
第一光源模組300包含一第一電路板310及多個第一發光元件320。第一電路板310設置於基座100,並將廣角鏡頭模組200圍繞於內。這些第一發光元件320電性連接於第一電路板310。每一第一發光元件320具有一第一照射角度θ 1及對應的第一光照範圍R1。這些第一發光元件320之第一光照範圍R1至少有部分相互重疊而共同組成一第一照射範圍。在本實施例中,第一發光元件320為紅外線發光二極體,且第一發光元件320之第一照射角度θ 1係以120度為例,但並不以此為限。此外,於一實施例中,第一發光元件320係設置在廣角鏡頭模組200下方,以有效避免光線進入廣角鏡頭模組200而產生漏光現象。 The first light source module 300 includes a first circuit board 310 and a plurality of first light emitting elements 320. The first circuit board 310 is disposed on the susceptor 100 and surrounds the wide-angle lens module 200. The first light emitting elements 320 are electrically connected to the first circuit board 310. Each of the first light-emitting elements 320 has a first illumination angle θ 1 and a corresponding first illumination range R1.

In the embodiment, the first illuminating element 320 is an infrared illuminating diode, and the first illuminating angle θ 1 of the first illuminating element 320 is exemplified by 120 degrees, but is not limited thereto. In addition, in an embodiment, the first light-emitting element 320 is disposed under the wide-angle lens module 200 to effectively prevent light from entering the wide-angle lens module 200 to cause light leakage.
每一第二光源模組400包含一第二電路板410、一第二發光元件420及一第三發光元件430。第二電路板410設置於基座100,且位於第一電路板310外圍。第二發光元件420與第三發光元件430分別設置並電性連接於第二電路板410。第二發光元件420具有一第二照射角度θ 2及對應的一第二光照範圍R2。第一照射角度θ 1大於或等於第二照射角 度θ 2。在本實施例中,第一照射角度θ 1係等於第二照射角度θ 2,但並不以此為限。第三發光元件430具有一第三照射角度θ 3及對應的一第三光照範圍R3。在本實施例中,第二照射角度θ 2大於第三照射角度θ 3,且第三照射角度θ 3小於第二照射角度θ 2或第一照射角度θ 1,但並不以此為限。 舉例說明,在本實施例中,第二發光元件420與第三發光元件430可為紅外線發光二極體,且第二發光元件420之第二照射角度θ 2係以120度為例,第三發光元件430之第三照射角度θ 3係以30度為例,但並不以此為限。採用第三照射角度θ 3為30度的第三發光元件430將有助於集中第三發光元件430的亮度並增加第三發光元件430的照射距離。在本實施例中,第二光源模組400的第二光照範圍R2及第三光照範圍R3至少有部分相互重疊而共同組成一第二照射範圍。在本實施例中,第二光源模組400包含第二發光元件420及第三發光元件430,但並不以此為限,在其他實施例中,第二光源模組400也可以僅包含具有較大照射角度的第二發光元件420。 Each of the second light source modules 400 includes a second circuit board 410 , a second light emitting element 420 , and a third light emitting element 430 . The second circuit board 410 is disposed on the susceptor 100 and located at the periphery of the first circuit board 310. The second light emitting element 420 and the third light emitting element 430 are respectively disposed and electrically connected to the second circuit board 410. The second light emitting element 420 has a second illumination angle θ 2 and a corresponding second illumination range R2. The first illumination angle θ 1 is greater than or equal to the second illumination angle Degree θ 2. In the embodiment, the first illumination angle θ 1 is equal to the second illumination angle θ 2 , but is not limited thereto. The third light emitting element 430 has a third illumination angle θ 3 and a corresponding third illumination range R3. In this embodiment, the second illumination angle θ 2 is greater than the third illumination angle θ 3 , and the third illumination angle θ 3 is smaller than the second illumination angle θ 2 or the first illumination angle θ 1 , but is not limited thereto. For example, in the embodiment, the second illuminating element 420 and the third illuminating element 430 may be infrared illuminating diodes, and the second illuminating angle θ 2 of the second illuminating element 420 is exemplified by 120 degrees. The third illumination angle θ 3 of the light-emitting element 430 is exemplified by 30 degrees, but is not limited thereto. The use of the third light-emitting element 430 with the third illumination angle θ 3 of 30 degrees will help concentrate the brightness of the third light-emitting element 430 and increase the illumination distance of the third light-emitting element 430. In this embodiment, the second illumination range R2 and the third illumination range R3 of the second light source module 400 at least partially overlap each other to form a second illumination range. In this embodiment, the second light source module 400 includes the second light emitting element 420 and the third light emitting element 430, but is not limited thereto. In other embodiments, the second light source module 400 may only include The second light-emitting element 420 has a larger illumination angle.
罩體500設置於基座100上,令罩體500與基座100包覆廣角鏡頭模組200、第一光源模組300及至少一第二光源模組400。 The cover 500 is disposed on the base 100, and the cover 500 and the base 100 cover the wide-angle lens module 200, the first light source module 300, and the at least one second light source module 400.
值得注意的是,如第4圖所示,第一光源模組300的光軸方向與第二光源模組400的光軸方向相異。進一步來說,第一發光元件320之光軸L1與底面110間遠離廣角鏡 頭模組200側的夾角θ a係異於第二發光元件420及第三發光元件430之光軸L2分別與底面110間遠離廣角鏡頭模組200側的夾角θ b。舉例來說,第一光源模組300之光軸L1與底面110的夾角θ a為90度,而第二光源模組400之光軸L2與底面110的夾角θ b為45度,使得第一光源模組300之光軸L1與底面110間的夾角θ a大於第二光源模組400之光軸L2與底面110間的夾角θ b。如此一來,可使得第一光源模組300之第一照射範圍涵蓋可攝範圍C之中央區域,而各個第二光源模組400之各個第二照射範圍涵蓋可攝範圍C的邊緣區域。由於本實施例之第二光源模組400設有亮度較為集中的第三發光元件430,故將有助於提升邊緣區域的亮度,進而提升攝影裝置10於夜間拍攝或於光線不足處拍攝的攝像品質。 It should be noted that, as shown in FIG. 4 , the optical axis direction of the first light source module 300 is different from the optical axis direction of the second light source module 400 . Further, the optical axis L1 of the first light-emitting element 320 and the bottom surface 110 are away from the wide-angle lens The angle θ a of the head module 200 side is different from the angle θ b between the optical axis L2 of the second light-emitting element 420 and the third light-emitting element 430 and the bottom surface 110 away from the wide-angle lens module 200 side. For example, the angle θ a between the optical axis L1 of the first light source module 300 and the bottom surface 110 is 90 degrees, and the angle θ b between the optical axis L2 of the second light source module 400 and the bottom surface 110 is 45 degrees, so that the first The angle θ a between the optical axis L1 of the light source module 300 and the bottom surface 110 is greater than the angle θ b between the optical axis L2 of the second light source module 400 and the bottom surface 110 . In this way, the first illumination range of the first light source module 300 can cover the central area of the visible range C, and each second illumination range of each of the second light source modules 400 covers the edge area of the visible range C. Since the second light source module 400 of the present embodiment is provided with the third light-emitting element 430 with relatively concentrated brightness, it will help to improve the brightness of the edge area, thereby improving the imaging of the photographing device 10 at night or in low light. quality.
在本實施例中,由於廣角鏡頭模組200的攝像距離係設定在拍攝1米以外的物品,而本實施例之攝像距離係以1米至5米為例。因此各光源模組可以設定第一照射範圍與各第二照射範圍例如在離鏡頭一米遠處彼此相互重疊,以期能夠涵蓋廣角鏡頭模組200的可攝範圍,此外更可以有效減少光源模組的個數,減少不必要的光能損耗,讓其發揮最大的效用。 In the present embodiment, since the imaging distance of the wide-angle lens module 200 is set to capture an item other than 1 meter, the imaging distance of the embodiment is 1 to 5 meters. Therefore, each light source module can set the first illumination range and each of the second illumination ranges to overlap each other, for example, one meter away from the lens, so as to cover the range of the wide-angle lens module 200, and further reduce the light source module. The number reduces the unnecessary loss of light energy and maximizes its utility.
請參閱第5圖。第5圖為根據本發明之第二實施例之攝影裝置之罩體以虛線表示的立體示意圖。本實施例與上述第1圖之實施例相似,故僅以相異處進行說明。 Please refer to Figure 5. Fig. 5 is a perspective view showing a cover body of a photographing apparatus according to a second embodiment of the present invention, which is indicated by a broken line. This embodiment is similar to the embodiment of Fig. 1 described above, and therefore only the differences will be described.
本實施例更包含多個反射件600,這些反射件600分別設於第一電路板310及各第二電路板410,且分別將各個第一發光元件320、各個第二發光元件420及各個第三發光元件430圍繞於內,用以進一步集中發光元件所投射出的光線而增加發光元件的亮度,且提高發光元件的照射距離。但並不以此為限,在其他實施例中,各個反射件600也可以僅設於各個第一發光元件320。於一實施例中,反射件600係可為燈杯。 The embodiment further includes a plurality of reflectors 600 respectively disposed on the first circuit board 310 and each of the second circuit boards 410, and each of the first light-emitting elements 320, the second light-emitting elements 420, and each of the first The three light-emitting elements 430 are surrounded to further concentrate the light emitted by the light-emitting elements to increase the brightness of the light-emitting elements and to increase the illumination distance of the light-emitting elements. However, it is not limited thereto. In other embodiments, each of the reflective members 600 may be disposed only on each of the first light emitting elements 320. In an embodiment, the reflective member 600 can be a light cup.
根據上述本發明所揭露的攝影裝置,第一光源模組的光軸方向與第二光源模組的光軸方向相異,使第一光源模組之第一照射範圍與第二光源模組之第二照射範圍涵蓋廣角鏡頭模組的可攝範圍,以提升光源模組的照射涵蓋範圍及照射距離,進而提升攝影裝置於夜間拍攝或於光線不足處拍攝的攝像品質,此外透過具有不同發光角度之發光元件的配置,不僅可以提升光源模組的照射涵蓋範圍,更可兼顧光源模組整體發光的均勻性,有效解決習知技術中產生之手電筒效應的問題。 According to the photographic device of the present invention, the optical axis direction of the first light source module is different from the optical axis direction of the second light source module, so that the first illumination range of the first light source module and the second light source module The second illumination range covers the range of the wide-angle lens module to enhance the illumination coverage and illumination distance of the light source module, thereby improving the image quality of the camera at night or in low light, and also having different illumination angles. The arrangement of the light-emitting elements can not only improve the illumination coverage of the light source module, but also take into account the uniformity of the overall illumination of the light source module, and effectively solve the problem of the flashlight effect generated in the prior art.
