COMPACT LENS TURRET ASSEMBLY

摘要

An electronic camera module incorporates a sensor unit ( 20 ) having a semiconductor chip ( 22 ) such as a CCD imager and a cover ( 34 ) overlying the front surface of the chip. An optical unit ( 50 ) includes one or more optical elements such as lenses ( 58 ). The optical unit has engagement features ( 64 ) which abut alignment features on the sensor unit as, for example, portions ( 44 ) of the cover outer surface ( 38 ), so as to maintain a precise relationship between the optical unit and sensor unit.
