Abstract: Obtaining a needed image has been difficult with conventional technology. A needed image can be obtained by an imaging device including an optical signal acquisition unit that performs imaging and acquires an optical signal, an original image acquisition unit that acquire two or more different original images using the optical signal, a selection unit that acquires one output image from candidate images including the two or more original images acquired by the original image acquisition unit, and an image output unit that outputs the output image acquired by the selection unit.

Abstract: To obtain an imaging unit, a lens barrel, and a portable terminal which can effectively suppress spring-back of solid-state imaging elements, while facilitating height lowering thereof. An imaging unit includes: a solid-state imaging element; and an imaging lens for forming a subject image on a photoelectric conversion part of the solid-state imaging element. An imaging surface of the solid-state imaging element is curved in a manner that a peripheral side is inclined toward an object side relative to a screen center. The imaging lens constrains the solid-state imaging element to prevent a radius of curvature of the imaging surface from varying. Thus, field curvature, distortion aberration, and comatic aberration are appropriately corrected.

Abstract: A technique is capable of improving the precision of a distance measurement made using a stereo camera, and is capable of reducing the size of a stereo camera device. The stereo camera is equipped with left and right imaging systems having left and right optical systems and left and right imaging elements, and derives the distance to an imaging target on the basis of an image signal acquired by imaging the imaging target by means of the left and right imaging systems. The light receiving surface of the left and right imaging elements in the left and right imaging systems is caused to bend in the direction of the optical axis so as to correct an aberration in the left and right optical systems.

Abstract: A workpiece conveying and feeding unit for conveying a long workpiece in the lengthwise direction to feed the workpiece to a cutting machine is disposed in the rear of the cutting machine. A workpiece conveying unit conveys the workpiece in the lengthwise direction of the workpiece into a workpiece conveying passage of the workpiece conveying and feeding unit. When a plurality of workpieces placed on the workpiece conveying unit are sequentially conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit to convey the workpieces to the cutting machine, the side surface of the workpiece which is conveyed to the workpiece conveying passage of the workpiece conveying and feeding unit by the workpiece conveying unit is detected by a side-surface detector.

Abstract: Providing imaging apparatus which can secure a wide angle of view with minimized distortion aberration thereby allowing the face of a person shot to be identified off the position right in front of the imaging apparatus or from a reasonably high location

Abstract: An eye image pickup device includes an object lens; an image pickup element, such as a CCD serving as an image pickup unit; a light shielding portion; and a light guide unit. The light shielding portion shielding one part of the pickup light path is coaxially positioned along a light axis of an optical image pickup system. The light guide unit guides visible light on the route of the guide light path leading to the object lens. A cross section of the guided visible light is similar to that of the light shielding portion, and the center of the visible light is coincident with the light axis. The cross-sectional area of the visible light is set substantially equal to or slightly larger than the effective cross sectional area of the light shielding portion with respect to the optical image pickup system along the light path.

Abstract: A method for conveying a long workpiece to a cutting machine includes the steps of conveying a long workpiece laterally to a feed conveyor positioned in parallel with the path line of the cutting machine by a cross conveyor extending in the lateral direction of the workpiece; stopping the cross conveyor when a workpiece reaches a regulating member provided above the cross conveyor, in a line parallel to the path line of the cutting machine; moving the feed conveyor with respect to the cutting machine path line in response to the workpiece width so that the feed conveyor is located at a position for selectively scooping up the workpiece; moving at least one of the feed conveyor or the cross conveyor in the vertical direction so that the workpiece is selectively loaded on the feed conveyor; and conveying the loaded workpiece to the cutting machine by the feed conveyor.
