    Abstract: A compound-eye capturing apparatus provided with a plurality of imaging devices captures a plurality of items of image data with the same image quality. First pixels for generating first pixel signals are arranged in a first pixel array part. Second pixels for generating second pixel signals are arranged in a second pixel array part. A first setting part sets an exposure time and a first gain for the first pixel signals on the basis of an appropriate exposure value. A second setting part adjusts the first gain on the basis of a difference in sensitivity between a first monocular camera module provided with the first pixel array part and a second monocular camera module provided with the second pixel array part, and sets the adjusted first gain as a second gain for the second pixel signals. A control part causes the first and second pixel array parts to be exposed over the exposure time. An amplification part amplifies the output first and second pixel signals by the first and second gains.

    Abstract: In the image capturing apparatus, the optical path difference producing member is disposed on the second optical path. Thereby, it is possible to suppress the amount of light when an optical image which is focused at the front of an optical image made incident into the first imaging device (front focus) and an optical image which is focused at the rear thereof (rear focus) are respectively imaged at the second imaging device and also to secure the amount of light on image pickup by the first imaging device. Further, in the image capturing apparatus, a position of the first imaging region and a position of the second imaging region on the imaging area are reversed with respect to the axis P in association with reversal of a scanning direction of the sample. Therefore, despite the scanning direction of the sample, it is possible to obtain a deviation direction of the focus position under the same conditions.

  • Patent number: 8848091
    Abstract: A new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels. In one preferred embodiment, the camera employs a digital micromirror array to perform optical calculations of linear projections of an image onto pseudorandom binary patterns. Its hallmarks include the ability to obtain an image with only a single detection element while measuring the image/video fewer times than the number of pixels or voxels—this can significantly reduce the computation required for image/video acquisition/encoding. Since the system features a single photon detector, it can also be adapted to image at wavelengths that are currently impossible with conventional CCD and CMOS imagers.

    Abstract: This document describes various apparatuses and techniques for rapid synchronized lighting and shuttering. These apparatuses and techniques are capable of capturing two images, where one of the images integrates multiple exposures during which an image area is illuminated by a light source and another of the images integrates multiple exposures during which the image is not illuminated by the light source. The image area can be illuminated by rapidly flashing the image area with the light source and synchronizing a shutter to permit one image sensor to capture an image when the image area is illuminated and another image sensor to capture the image area when the image area is not illuminated. These two images can be captured concurrently or nearly concurrently, thereby reducing or eliminating motion artifacts. Further, these apparatuses and techniques may do so with slow and relatively low-cost cameras and relatively low computational costs.

  • Patent number: 8638387
    Abstract: A sighting system is disclosed, comprising a housing with small upper mirror mounted in its upper center, redirecting light from a single objective lens set, and a larger lower mirror mounted coaxially relative to the lens set and upper mirror, both mirrors set at 45° and redirecting light at 90° angles to the lens set. The smaller mirror is positioned closer than the lower mirror to the lens set. A night camera system is used for receiving an image through the lens set redirected by the lower mirror and amplified through an intensifier before transmission to a video display monitor(s). A day camera system receiving the image from the lens set redirected by the smaller mirror transmits the image to the monitor(s) for separate display of the image, enabling simultaneous capture of the optimum amount of light by each camera, maximizing the housing's diametrical space to receive incoming light.
