Patent application numberDescriptionPublished
20090008683IMAGING APPARATUS - An imaging apparatus comprises: a semiconductor imaging device having a plurality of photodiodes and a color filter; and an imaging optical system for guiding light from a subject to the semiconductor imaging device, where a diameter of an aperture (01-08-2009
20090168190Imaging Device - It is an object of the present invention to provide an imaging device that, even if the optical axis of the multifocal lens has a deviation resulting from its decentered surfaces, can prevent an image from being deteriorated by the low precision lens. The imaging device 07-02-2009
20090168204LENS, LENS UNIT, AND IMAGING DEVICE USING THE SAME - A lens is provided which is configured so that the dimensional accuracy of the lens surface can be evaluated easily and accurately, and the control of the accuracy of the lens can be easily performed. The lens comprises a lens effective part having lens surfaces formed around an optical axis as the center and an edge part in a doughnut shape as viewed in a plan view, which is extended along the outer periphery of the lens effective part. The edge part and the lens effective part are molded simultaneously, and annular indices around the optical axis as the center, with which the dimensional accuracy of the lens surfaces can be detected, are formed on both the surfaces of the edge part.07-02-2009
20100025789IMAGING DEVICE, METHOD FOR MANUFACTURING THE IMAGING DEVICE AND CELLULAR PHONE - An imaging device includes a lens (02-04-2010
20100025792IMAGE PICKUP APPARATUS, MANUFACTURING METHOD THEREOF, AND MOBILE TERMINAL - Degradation of a picked-up image quality occurs because of entry or a move of dust in the internal space of an image pickup apparatus. An image pickup apparatus for decreasing degradation of the image quality by capturing dust is provided. An image pickup apparatus 02-04-2010
20100045846IMAGE PICKUP DEVICE, METHOD OF MANUFACTURING THE SAME, AND MOBILE TERMINAL DEVICE - An excellent image pickup device whose size and thickness are reduced is realized with a simple structure, and thus the slimming down of a mobile terminal device is accomplished. A slim image pickup device in which a plate-like member 02-25-2010
20100220404PIEZOELECTRIC ACTUATOR DEVICE, IMAGE PICKUP UNIT AND MOBILE TERMINAL APPARATUS - An object of the invention is to provide an actuator device that realizes improvements in impact resistance as well as size reduction and thickness reduction of the device.09-02-2010
20110045869IMAGING APPARATUS - An imaging apparatus comprises: a semiconductor imaging device having a plurality of photodiodes and a color filter; and an imaging optical system for guiding light from a subject to the semiconductor imaging device, where a diameter of an aperture (02-24-2011
