20100079657 | IMAGING APPARATUS FOR READING INFORMATION - The optical path of the light having spread at each point of an object to be shot is limited by an iris unit of a density filter. Since the density filter unit has a desired transmittance characteristic, the amount of the light passing through the density filter unit continuously changes from the center of the luminous flux toward the periphery. After the luminous flux forms an image on the image forming surface, it spreads toward the light-receptive surface of an image sensor, and becomes an image spreading on the light-receptive surface in a predetermined range. | 04-01-2010 |
20100079825 | IMAGING APPARATUS FOR READING INFORMATION - A position Z of an image sensor is moved to an initial position A (image forming position) in a Z axis direction. An exposing operation is performed at a position A, and it is determined whether or not an exposing time counted by a timer has reached ta. If the exposing time has reached ta, an image sensor | 04-01-2010 |
20100079826 | IMAGING APPARATUS FOR READING INFORMATION - A liquid crystal panel includes an iris unit for limiting the incident range of light from an object to be shot, and a filter unit for assigning a exposure energy distribution varying with the position to incident light whose incident range is limited by the iris unit. The control unit controls the ON time and the OFF time of each pixel of the liquid crystal panel, and then a low pass filter operation on the captured image as an image processing can be optically replaced. | 04-01-2010 |
20120154672 | ILLUMINATION OPTICAL SYSTEM OF IMAGE CAPTURING DEVICE - An illumination optical system of an image capturing device that is compact and low cost and that achieves a reduction in specular noise is provided. An illumination optical system | 06-21-2012 |
20130128571 | PRISM PLATE, ILLUMINATION OPTICAL SYSTEM OF IMAGING DEVICE, AND FORMING DIE OF PRISM PLATE - A prism plate is obtained which gives directivity to the exit directions of illumination light and enables control of the illuminance distribution. A prism plate | 05-23-2013 |
20130329437 | ILLUMINATION OPTICAL SYSTEM FOR IMAGE PICKUP APPARATUS - An illumination optical system for an image pickup apparatus includes a plurality of light sources arranged in a circular loop pattern and a prism plate shaped like a circular loop. the prism plate includes a prism surface at which illumination light from the light sources enters and on which a plurality of prism columns arranged in a circular loop pattern in a circumference direction of the prism plate are formed and an outgoing surface from which the illumination light is emitted. the prism surface includes a flat portion on at least one of a peak formed by each of the plurality of prism columns and a trough formed between the plurality of prism columns. the flat portion is substantially parallel to a tangential direction of the prism plate. | 12-12-2013 |

20160047977 | OPTICAL FIBER AND PROCESS FOR PRODUCING THE SAME - A process for producing an optical fiber including a glass fiber, a primary resin coating layer which covers the periphery of the glass fiber, and a secondary resin coating layer which covers the periphery of the primary resin coating layer, wherein the primary resin coating layer is formed by curing a curable resin composition which includes one or more oligomers, one or more monomers, and a reaction initiator, the curable resin composition containing a one-end-capped oligomer in an amount of 30% by mass or larger based on all the oligomers. The optical fiber produced by this production process does not deteriorate in low-temperature transmission loss, because the primary resin coating layer is inhibited from generating voids even when having a low Young's modulus. | 02-18-2016 |
