20080310032 | ZOOM LENS SYSTEM AND IMAGE PICKUP APPARATUS INCLUDING THE SAME - A simple, compact, high-zoom-ratio zoom lens system exhibiting high optical performance at all zoom positions is provided. The system includes, in order from the object side to the image side, first to fourth lens groups having positive, negative, positive, and positive refractive powers, respectively. The first-to-second-lens-group distance becomes the smallest during zooming. The first lens group resides closer to the object at a telephoto end than at a wide-angle end. The lens groups move such that the second-to-third-lens-group distance is smaller and the third-to-fourth-lens-group distance is larger at the telephoto end than at the wide-angle end. The second lens group includes, in order from the object side to the image side, negative and positive lens elements. First-to-second-lens-group distances d1w and d1t at the wide-angle end and at the telephoto end, respectively, and the smallest first-to-second-lens-group distance d1min obtained during zooming are appropriately set. | 12-18-2008 |
20110116173 | ZOOM LENS SYSTEM AND IMAGE PICKUP APPARATUS HAVING SAME - A zoom lens system includes, in order from the object side to the image side, first, second, third, fourth lens units respectively having positive, negative, positive, and positive refractive powers. The lens units move from a wide-angle end to a telephoto end such that intervals between adjacent lens units vary during zooming. The first lens unit consists of first-a and first-b lens elements respectively having negative and positive refractive powers, and the second lens unit consists of second-a, second-b, and second-c lens elements respectively having negative, negative, and positive refractive powers. n12 and ν12 respectively represent the refractive index and the Abbe number of the first-b lens element, and fw and ft respectively present the focal length at the wide-angle end and the telephoto end of the zoom lens system. Values for at least n12, ν12, fw and ft are appropriately set based on predetermined conditions. | 05-19-2011 |
20120113528 | IMAGE TAKING APPARATUS - An image taking apparatus including a zoom lens; and a solid-state image pickup element, wherein the zoom lens includes, a first lens unit; a second lens unit; and a third lens unit, the first lens unit, the second lens unit and the third lens unit moving during zooming, wherein the first lens unit includes a lens | 05-10-2012 |
20140198231 | IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS AND IMAGE PROCESSING METHOD - The image processing apparatus includes an image acquirer configured to acquire an input image produced by image capturing through a zoom lens whose magnification is variable, and a processor configured to perform an image restoration process using an image restoration filter produced on a basis of information on aberration of the zoom lens. The processor is configured to not perform the image restoration process on a central image area of the input image produced by the image capturing through the zoom lens set in a specific magnification state and to perform the image restoration process on a specific image area more outer than the central image area of that input image. | 07-17-2014 |

20140313259 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - The present invention provides a liquid ejecting head provided with a suction port capable of avoiding the return of mists, which have once sucked through a suction port, to the suction port. In view of this, the inner diameter L of a suction tube for allowing liquid mists taken in through the suction port to pass is designed such that a meniscus is formed before a liquid droplet adhering to the inside of the suction tube grows enough to move toward the suction port. | 10-23-2014 |
20150085014 | LIQUID EJECTION APPARATUS, MIST COLLECTING MECHANISM AND MIST COLLECTION METHOD - There are provided a mist collecting mechanism capable of efficiently sucking and collecting an air blown out from a blow-out unit and a liquid ejection apparatus including the mist collecting mechanism. The mist collecting mechanism includes a suction port configured to suck an air containing mists. Moreover, the mist collecting mechanism includes a first blow-out port that blows out an air in order to guide the air containing mists to the suction port. Moreover, the mist collecting mechanism includes a second blow-out port that blows out an air in order to adjust a position, toward which the air blown out from the first blow-out port flows, so that the air blown out from the first blow-out port is appropriately sucked by the suction port. | 03-26-2015 |
20150085015 | PRINTING APPARATUS - Air blown out from one blowing-out opening of a pinch roller which is within a predetermined angle range forms an air flow of a flow rate Fc which heads for a region between a suction mechanism and a print medium. This makes it possible to efficiently guide the air blown out from the blowing-out opening into the region, and as a result, ink mist can be collected satisfactorily even in a case where the amount of air blown from the pinch roller is relatively small. Further, in this case, the flow rate Fe of a flow blown from the pinch roller is appropriately determined, whereby the suction mechanism can collect substantially 100% of air and ink mist flowing into the region. | 03-26-2015 |
