图4.2 camera 组成图 4.1、镜头(Lens) 镜头是将拍摄景物在传感器上成像的器件,它通常由几片透镜组成。从材质上看,摄像头的镜头可分为塑胶透镜和玻璃透镜。 图4.1.1 镜头 镜头有两个较为重要的参数:光圈和焦距。 光圈是安装在镜头上控制通过镜头到达传感器的光线多少的装置,除了控制通光量,光圈还具有控制景深的功...
CCM(Camera Compact Module)一般译为摄像头模组,主要由镜头系统(lens system,一般会集成红外滤光片IR Filter),图像传感器(Image Sensor,CMOS or CCD)、ISP(Image Signal Process)(*1),串行器(Serializer) 构成(*2)。基本原理是通过外部光线照射在物体上,经过反射、折射后穿过镜头(Lens),再经过滤光片滤波投射到图...
