The wafer level camera module additionally includes a first conductive via penetrating through the camera module to be electrically connected to the first piezoelectric thin film. The camera module further includes a second conductive via penetrating through the camera module to be electrically connected to the second piezoelectric thin film. | 2017-06-15 |
20170168266 | IMAGING LENS ASSEMBLY, IMAGE CAPTURING APPARATUS AND ELECTRONIC DEVICE - An imaging lens assembly, including, in order from an object side to an image side: a first lens element having negative refractive power; a second lens element with positive refractive power having an image-side surface being convex; a third lens element, a fourth lens element with positive refractive power having an object-side surface being concave and an image-side surface being convex; a fifth lens element with negative refractive power having an image-side surface being concave, at least one convex shape on the image-side surface in an off-axial region, and both of object-side and image-side surfaces thereof being aspheric; wherein the imaging lens assembly has a total of five lens elements. | 2017-06-15 |
20170168267 | OPTICAL IMAGE CAPTURING SYSTEM - An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive force. The seventh lens can have negative refractive force, wherein both surfaces thereof are aspheric, and at least one surface thereof has an inflection point. The lenses in the optical image capturing system which have refractive power include the first to the seventh lenses. The optical image capturing system can increase aperture value and improve the imagining quality for use in compact cameras. | 2017-06-15 |
