    摘要: A subsystem is disclosed providing a steerable-beam light source (10). An array (16) of micromechanical reflectors may be disposed to selectively direct portions of light from a light source (14) to selected targets (O) in a scene, such as for providing composed illumination for still or video photography. The array (16) of reflectors may be continuously steerable, thereby achieving more than the mere inefficient patterning of illumination light available from prior art projection approaches, but instead efficiently redirecting light to the desired regions of the scene. The subsystem may be sufficiently compact so as to permit integration with a compact camera into a cellular telephone, a tablet computer, a laptop computer, a digital still-image camera, a digital video-image camera, and so on. The array (16) may be operated in conjunction with a camera controller to selectively illuminate one or more targets (O) of focus or zoom or omit illumination of undesirable image regions.

    摘要: An illumination device for illuminating a camera's field of view, comprising a light source (15), and a reflector unit (16) having reflecting sections (21, 22, 23, 24, 25) is provided. Each reflecting section (21, 22, 23, 24, 25) is associated with a light distribution, wherein the light distributions for different reflecting sections (21, 22, 23, 24, 25) are different. The reflector unit (16) is arranged such that light emitted by the light source (15) is deflected by one of said reflecting sections (21, 22, 23, 24, 25) being selected based on the camera's field of view. A method for illuminating a camera's field of view is also provided.

    摘要: 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 20 of an image capturing device applies light to an object 11 to be imaged to capture an image by receiving reflected light from the object 11 to be imaged by means of an image sensor 12. The illumination optical system comprises a plurality of LEDs 14 arranged around the image sensor 12, and a ring-shaped prism plate 22 with a prism surface 24 facing the plurality of LEDs 14 in order to apply light from the plurality of LEDs 14 to the object 11 to be imaged, wherein the prism surface has a row of prisms comprising a number of radially arranged edge lines 23 formed circumferentially.

    摘要: The present invention provides an illuminator system comprising a dual reflector system and a linear light source. The dual reflector system comprises a primary and secondary generally cylindrical reflector, which collimate light from a linear light source in two planes. The linear light source may comprise many light emitting devices, and may emit light in a strobe or continuous fashion. The reflectors may be of many cylindrical shapes, and may include additional mirror segments to capture light otherwise not collimated. Further, the reflectors may be in various configurations of position and orientation with respect to one another, and may be adjustable in this respect. The system is more efficient than existing illuminators, is compact, all reflective (no color), lightweight, simple and inexpensive to manufacture. The system has applications to many fields including machine vision, surveillance, spectroscopic inspection of materials, and converting linear light sources into rectangular beam spot lights.

    摘要: Disclosed is an imaging apparatus provided with: a light irradiation unit which irradiates a target area with light; a differential image generation unit which generates a differential image between a first image which was taken in synchronization with the irradiation period during which the light irradiation unit irradiates the light and a second image which was taken outside the irradiation period; a transmittance estimation unit which estimates the light transmittance of an object in the target area; and a light exposure adjustment unit which adjusts the exposure based on the estimation result from the transmittance estimation unit. The transmittance estimation unit estimates the transmittance of the object from at least one of the first image, the second image, and the differential image.
