However, during the daytime, any object is reflected by the sunlight and then reflected by the light. After shooting by the camera, the visible light reflected by the object itself is also reflected by the infrared light in the sunlight to the surveillance camera. The video is not visible on the screen, but the infrared light will cause the color of the object to be under-reduced. 7 The color of the image observed through the screen is not the original color of the object. In order to solve the problem of narration, there is a surveillance camera (7 〇) sold in the market with an image sensing component (not shown) and a filter (7 1 ) at the lens end, such as a basket. 1 1 ; As shown in the fifth and sixth figures, by mechanically switching the filter (7 ]), # 丄 can be used to shield the infrared light into the lens during the day (7 1 ), and at night This is not necessary. The biggest shortcoming of the camera is that the installation of the filter (7 1 ) takes up a lot of space. There is another kind of surveillance camera (70) on the market in Meguro. The M294668 is shown in the seventh figure. Two sets of image sensing elements # (not shown) correspond to two lenses (7 2 ) ( 7 3 ), the lens (72) is provided with an infrared filter (not shown), and the other lens (73) No, by the detection of the image sensing component, when the daytime light is ^, the image is recorded by the lens (72) with the infrared lens; and when the night is insufficient, the light is not provided. The infrared filter and the lens (73) record the image. Due to the development of technology, many equipments have begun to be designed and manufactured in a light, thin, short, and small direction. Although the aforementioned surveillance cameras have eliminated the volume occupied by the installation of a cymbal, the use of dual lenses is not only costly. The cost of a lens unit is also increased because of the need to provide two sets of image sensing elements. Therefore, how to reduce the size of the surveillance camera and save costs will be an important issue.
