Description of the invention: [Technical field to which the invention pertains] The present invention belongs to the age of a camera device, and in particular to the placement of a photosensitive device in a shovel-like rib, so that a plurality of maps are obtained for the control device of the Lai-Mou paste A camera like an effect. < 5 [Prior Art] The conventional imaging devices basically use a CCD imaging photosensitive chip or a CMOS imaging photosensitive chip (SENSOR) as an image-to-electronic information converter (commonly referred to as CCD or CMOS), and the following is a CCD. There are 1 examples of camera-sensing wafers. Of course, all of the following descriptions are equally applicable to CM0S or CCD and CMOS hybrids. The camera device projects the image onto the CCD through an optical lens (the same is true for CMOS), and the image is converted into an electrical signal by the CCD, and processed by the electronic system for subsequent processing such as recording, display, or signal compression. Generally, a camera refers to a system that converts an image into an image communication electrical signal, consisting of an optical lens, a set of three or a single CcD I5 photoreceptor, and its associated electronic circuitry. The CCD is divided into two categories: black and white (monochrome) and color. The color CCD chrominance signal is generated by receiving light from each photosensitive unit of the CCD sensor. The unit is covered with a specific color (red, green, blue). The color mask device is produced by subsequent circuit processing. In view of the problem that the color image obtained by the single-chip CCD after covering the 2 〇 micro-filter is not perfect, a two-CCD camera composed of three CCDs which respectively convert red, green and blue image information and have almost the same characteristics is invented. The three CCDs are not used alone, and must be used in combination to achieve the actual color effect. Based on cost and performance considerations, only one CCD sensor can be mounted in the camera of the prior art, and the ccd is used for sensitization.
又由於CCD晶片的半導體特性要求彩色CCD攝像頭必須外加 10 一濾色鏡片才能在陽光下獲得真實的顏色效果，而此濾色鏡片 夕疋採用具有紅外線濾、光特性的紅外線渡色鏡，一般只能透過 可見光，而不能透過紅外光，所以此時的彩色攝像頭即使有紅 1291305 度，或彩色信號的光電轉換，或者黑白或者彩 的θ w此、們％之為單片ccd攝像頭。綱上根據其内安裝 t f白ccd或彩色咖，稱為黑白攝像頭或彩色攝像頭。 早形色CCD感光器件的靈敏度相對黑白CCD感光器件的靈 敏度要低很夕。彳>色攝像頭在自天或光線比較充足的條件下， 可^拍攝到鮮盤、亮麗的彩色圖像，而在比較暗的環境下，如 在夜間自然光（月光、星光）或小範圍燈光的微弱照度下，由 於彩色CCD感光靈敏度低，所以不能得到良好的彩色圖像。 外線輔助照明也無法獲付好的圖像效果。當然可以挪開此擴色 片，利用鏡頭直接看紅外光，但仍不能解決彩色CCD感光靈 is敏度低的問題。要想在此種低照度下獲得良好的圖像效果，只 能使用感光靈敏度高許多的黑白CCD晶片攝像頭。但是，使 用黑白攝像頭雖然解決了低照度的問題，在白天或光線較亮情 況下也只能獲得黑白圖像’黑白圖像的信息量彳氏於彩色圖像， 也不能象彩色攝像頭那樣輸出亮麗的彩色圖像，這又是用戶不 2〇希望的。雖然在技術上可以採用電子控制的方法，使得原來是 彩色的攝像頭，只取其亮度信號，但此時即使獲得的是黑白圖 像信號，仍然沒有解決此彩色CCD的感光靈敏度低的問題。 所以現有技術裏，利用攝像機裏僅有一片CCD彩色感光器件 在照明度好時可以獲得良好的彩色圖像信號，但是當光照度低 ⑧ 5 1291305 =’，其圖像效絲差(即使此時只取其黑自圖像效果依然很 差）’比起此低照度下黑白CCD的圖像效 … 在邊境線、保細或高 5時天時m得良好的圖像效果’但夜裏或低照度 圖像效果。針對以上問題，曰本 有:專利產品，它在攝像頭殼體内採用-片高槽次 .敏度的祕CCD，自天或絲照度高時，在綱盥ccd 之間有-片紅外光濾色鏡，以獲得真實的彩色圖像信號，夜晚 或先線照度低時，由光電探測器控制一機械系統將此濾色鏡移 10，，使得此CCD可喊受紅外線(#然此時紅外細像不再是 彩色的了）’但是即使採用了這個方法，所獲得的暗環境的圖 像效果比起一支一般槽次、感光靈敏度高的黑白CCD晶片所 輸出的圖像仏號還是要差很多。當然如果同時安放以上兩個單 獨為彩色及黑白攝像頭，在白天或光線比較充足的光照條件下 I5使用彩色攝像頭，而在晚上或照度低時改為使用黑白攝像頭， 如此分別使用是可以兼顧亮和暗條件下都可以獲得好的圖像 效果，可是成本將提高許多(尤其是要每個獨立的攝像頭都使 用一個價格昂貴的光學鏡頭），沒有實際實用價值。 20【發明内容】 本發明所欲解決的技術問題是提供一種新的攝像裝置，該 攝像裝置除了利用現有技術外，使用一個鏡頭，在殼體内配備 兩個或多個感光器件，以在不同的應用情況下，皆可得到所需 的成像效果。Moreover, due to the semiconductor characteristics of the CCD chip, the color CCD camera must be supplemented with 10 filter lenses to obtain a true color effect in the sunlight. This filter lens uses an infrared color filter with infrared filter and optical characteristics, which can only be transmitted through the lens. Visible light, but not through infrared light, so the color camera at this time even if there is red 1291305 degrees, or photoelectric conversion of color signals, or black and white or color θ w this, we are a single ccd camera. According to the installation of t f white ccd or color coffee, it is called black and white camera or color camera. The sensitivity of the early-color CCD sensor is lower than that of the black-and-white CCD sensor.彳>The color camera can capture fresh discs and bright color images in the light or in the light, but in darker environments, such as natural light at night (moonlight, starlight) or small range of lights. Under the weak illuminance, since the color CCD has low sensitivity, a good color image cannot be obtained. External line-assist lighting also does not pay good image effects. Of course, this color expansion film can be removed, and the infrared light can be directly viewed by the lens, but the problem that the color CCD photosensitive sensitivity is low can not be solved. In order to obtain good image quality under such low illumination, only black and white CCD wafer cameras with much higher sensitivity can be used. However, the use of a black-and-white camera solves the problem of low illumination. In the daytime or when the light is bright, only black and white images can be obtained. The amount of information of the black and white image is in the color image, and the output cannot be as bright as the color camera. The color image, which is again the user's hope. Although it is technically possible to adopt an electronically controlled method, the original color camera is only taken with its luminance signal, but even if a black and white image signal is obtained, the problem of low sensitivity of the color CCD is not solved. Therefore, in the prior art, only one CCD color sensing device in the camera can obtain a good color image signal when the illumination is good, but when the illuminance is low 8 5 1291305 = ', the image effect is poor (even if only Take the black self-image effect is still very poor) 'The image effect of the black and white CCD under this low illumination... Good image effect at the border, fine or high 5 o'clock, but the night or low illumination Image effect. In response to the above problems, Sakamoto has: a patented product, which uses a high-slot sensitivities CCD in the camera housing. When the illuminance is high, there is a piece of infrared light filter between the ccd To obtain a true color image signal, when the night or the first line illumination is low, a mechanical system controlled by the photodetector shifts the color filter by 10, so that the CCD can be shouted by infrared rays (# then the infrared fine image is no longer It is colored.) But even with this method, the image of the dark environment obtained is much worse than the image nickname output by a black-and-white CCD chip with a typical slot and high sensitivity. Of course, if the above two separate color and black-and-white cameras are placed at the same time, the I5 uses a color camera during daytime or under sufficient light conditions, and instead uses a black-and-white camera at night or when the illumination is low, so that it can be used separately. Good image quality can be obtained in dark conditions, but the cost will increase a lot (especially if each independent camera uses an expensive optical lens), there is no practical value. 20] SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a new imaging device that uses two lenses in the housing, in addition to the prior art, to use different lenses. In the case of application, the desired imaging effect can be obtained.
