1、CameraModule구조Lens:Barrel안에Lens구성품으로되어있음.Housing:LensFocusing을맞추기위한용도로사용IRCutFilter:적외선영역을일부차단하는기능을가진GlassImageSensor:CMOSImageSensor로ImageSensor+ISP,또는ImageSensoronly로구성되어있음.Substrate(기판):HPCB,RigidFlexPCB,FlexPCB,Ceramic,Glass기판등이있음.COBvsCOFCameraModule에적용되고있는패키징-CO

2、B(ChiponBoard):BareChip을PCB나FlexibleBoard위에직접장착,WireBonding후HousingAss’y로밀봉-COF(ChiponFPCB):BareChip과FPCB를Flip-chipBonding한후HousingAss’y로밀봉StructureStructureofofAFAFModuleModule구동방식Sensor로부터나온영상데이터를AFControlchip에서받아영상을분석하여그결과에따라MicrostepMotor를구동시키기위한신호를생성,MotorDriverI

3、C에서는그신호에따라Motor를구동하여Focusing을맞추게된다.영상분석알고리즘은EdgeDetection을하여그결과를바탕으로Motor의구동방향및구동거리등을계산하여Motor를제어,Focusing을맞추게된다.영상분석알고리즘의적용은Phone상의Basebandchip에서Software적으로구현이가능하나,처리시간및Baseband칩의처리부하등이증가하여실시간처리가어려워지는단점이발생한다.제작하려는모듈은이러한점을감안,Module내에영상분석및처리를위한Chip을탑재하여Phone상에서아무런처리없이모
