发明名称 IMAGE LENS ASSEMBLY AND IMAGE CAPTURING DEVICE
摘要 An image lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. The first lens element with positive refractive power has a convex object-side surface. The second lens element has positive refractive power. The third lens element has refractive power. The fourth lens element has refractive power. The fifth lens element with negative refractive power has a concave object-side surface, wherein both of the surfaces of the fifth lens element are aspheric. The sixth lens element with refractive power has a concave image-side surface, wherein the image-side surface thereof has at least one inflection point, and both of the surfaces of the sixth lens element are aspheric. The image lens assembly has a total of six lens elements with refractive power.
