A zoom lens assembly may enlarge/reduce an image without shifting a position of a lens set. A housing (301), a zoom lens unit (210) and a drive unit may be provided. The zoom lens unit may include a plurality of lenses (310) stationarily arranged within the housing by being spaced apart in prescribed distance from each other along an optic axis. The plurality of the lenses respectively have variable refractive indexes without a position shift. The drive unit may pressurize a prescribed one of the lenses to vary the refractive index of the prescribed lens. The controller (180) may control the drive unit to change a focal distance of the zoom lens unit (210) to enlarge or reduce an image. |
