CAMERA MODULE FOR A PORTABLE TERMINAL CAPABLE OF PHOTOGRAPHING IN DAYTIME AND NIGHTTIME BY INSERTING AND EXTRACTING INFRARED RAY BLOCKING FILTER OF AN OPTICAL SYSTEM EMBEDDED IN A CAMERA MODULE

摘要

PURPOSE: A camera module for a portable terminal is provided to obtain a clear image by correcting a chromatic aberration of a near-infrared radiation area using fold optical element.;CONSTITUTION: A lens group(130) projects income light to an upper plate(110) by successively including a plurality of arranged lens. An aperture(140) controls a light quantity income from a first lens by arranged to a front direction of the lens group. An infrared block filter(120) blocks an infrared ray including the light projected to the upper surface by being installed to enable the filter to be inserted or extracted between the aperture and the upper side. A diffractive optical element(150) corrects chromatic aberration projected to the upper surface by being arranged between the front direction of the aperture and the upper surface.;COPYRIGHT KIPO 2011
