1.3CCD: 一般的摄像机只有一个CCD,而3CCD摄像机则有3个CCD芯片,并且R、G、B(红、绿、蓝)三原色分别由3个芯片来处理,因此它的色彩饱和度及解析度会比一般单CCD摄像机高很多。 2.何谓广角镜头及长焦镜头广角镜头:又叫短焦距镜头,根据焦距的长短又有广角与超广角镜头之分,其特点是:焦距短、视场角大、拍摄景物范围广、景深大。长焦镜头:又叫望远镜头,其拍摄效果刚好和广角镜头相反。 3.何谓光学变焦及数字变焦光学变焦:光学变焦是通过光
1.3CCD: The general camera has only one CCD, while the 3CCD camera has three CCD chips, and R, G, B (red, green and blue) three primary colors are processed by three chips, so its color saturation and resolution Degree than the average single CCD camera much higher. 2. What is wide-angle lens and telephoto lens Wide-angle lens: also known as short focal length lens, according to the length of the focal length and wide-angle lens and super-wide angle, which is characterized by: short focal length, wide field of view, shooting a wide range of scenery, depth of field. Telephoto lens: also known as the telescope head, its shooting just the opposite and wide-angle lens. 3. What is optical zoom and digital zoom Optical zoom: optical zoom is through the light
