PURPOSE: A camera module is provided to reduce the moving distance of optical lens in optical axis direction by change of the refractive index of lens in zone function. CONSTITUTION: A zoom lens assembly(100) magnifies or reduces an image which subject light is shown between a light incoming unit and an image photographing unit(400). An AF(AutoFocus) lens assembly(200) controls the focus of the object light. A driving unit(500) moves at least one among the zoom lens assembly or the AF lens assembly along axis direction of the subject light. According to the applied voltage, variable refraction units(120,220) changeably change one or more refractive index among the zoom lens assembly or the AF lens assembly.
