A digital imaging system and method using multiple cameras arranged and aligned to create a much larger virtual image sensor array. Each camera has a lens with an optical axis aligned parallel to the optical axes of the other camera lenses, and a digital image sensor array with one or more non-contiguous pixelated sensors. The non-contiguous sensor arrays are spatially arranged relative to their respective optical axes so that each sensor images a portion of a target region that is substantially different from other portions of the target region imaged by other sensors, and preferably overlaps adjacent portions imaged by the other sensors. In this manner, the portions imaged by one set of sensors completely fill the image gaps found between other portions imaged by other sets of sensors, so that a seamless mosaic image of the target region may be produced.

What is described here is an antireflective coating comprising a carrier layer consisting of an optically transparent material, which, at least on one surface side, presents antireflective properties with respect the wavelengths of the radiation incident on the surface. Moreover, methods of producing the coating are described.The invention excels itself by the provision that the antireflective surface side presents a surface roughness with stochastically distributed structures-the so-called macro structures-and that the macro structures are additionally modulated with surface structures presenting a periodic sequence-the so-called micro structures-which present period or cycle lengths smaller than the wave lengths of the radiation incident on the antireflective surface.

The first pole piece is provided with a planar coil having a first side facing the yoke and a second side facing the yoke. A balancing member is arranged on the second side of the planar coil to counterbalance the attractive force between the planar coil and the yoke. The other pole piece may also be provided with a corresponding balancing member.

A view finder according to the present invention has an electroluminescence display element which displays an image of an object, and an optical element which magnifies the image.

An optical unit for forming an object image according to the present invention comprises: a reflection member for banding an optical axis of the optical unit; a front lens group arranged closer to an object side of the optical unit than the reflection member; a rear lens group arranged closer to an image forming side of the optical unit than the reflection member; and a driver for driving the optical unit. The driver drives the reflection member and the front lens group in a predefined first direction and in a predefined second direction.

Talbot imaging systems comprising a Talbot element, a phase gradient generating device, a light detector, and a processor. The Talbot element repeats a Talbot image at a distance from the Talbot element. The phase gradient generating device scans the Talbot image at a plane at the distance from the Talbot element by incrementally changing a phase gradient of a light field incident the Talbot element. As the Talbot image is scanned, the light detector captures time varying data associated with light altered by an object located at the distance from the Talbot element. The processor reconstructs an image of the object based on the time-varying light data.

For applying a motion filter of a video stabilization system to a sequence of video frames, an estimate of a motion in the current video frame compared to a first video frame of the sequence of video frames is received. Based on the received motion estimate and on at least one state variable of the motion filter, a correction value for the motion in the current video frame is computed. The at least one state variable is updated in the computation. In case the computed correction value exceeds a system constraint of the video stabilization system, the at least one state variable is adjusted in accordance with an extent by which the system constraint is exceeded. The correction value is then recomputed based on the motion estimate and on the adjusted state variable.

A method and system to convert an electronic image file described in a page description language containing both contone and non-contone image objects to an intermediate binary format image. The intermediate format image separately encodes the contone and non-contone image objects. The contone image objects are edge-tagged. Prior to printing, the intermediate binary format page image is separated into the contone and non-contone image objects. The contone image objects are converted back to a contone form using the edge tagging to modify the filter weights of a digital filter. The non-contone image objects are converted to contone form by means of a pattern matching scheme.

An image recording apparatus includes: a carriage that carries a recording head capable of recording an image on a recording medium and reciprocates in a main scanning direction; a substantially box-shaped main frame having an open upper side and a pair of side plates extending in a sub-scanning direction orthogonal to the main scanning direction; and first and second guide members over which the carriage extends and by which the carriage is guided, the first and second guide members being disposed to be apart from each other by a predetermined distance in the sub-scanning direction, extended in the main scanning direction at the upper side of the main frame and fixed to the pair of side plates.

A display illumination module for the illumination of a rear-projection screen is provided in which an array of light sources are positioned adjacent to an optical modulating array layer for modulating the transmission of light emitted by the light sources. The light sources emit light within a defined angular range, and the optical modulating array layer is positioned relative to the array of light sources so that light from adjacent light sources does not overlap with the optical modulating array layer. One or more display modules may be incorporated into a display system that further comprises a rear projection screen that is preferably spatially offset from the optical modulating array layer so that light from adjacent light sources of a common colour overlaps on the screen. A composite display with seamless edge blending may be obtained by tiling multiple display illumination modules behind a common rear-projection screen.

An x-ray and gamma-ray radiation energy imaging device has its semiconductor detector substrate and semiconductor readout/processing substrate both mounted on opposite sides of, and electrically communicating through, an intermediate substrate. The substrates are all substantially planar with the top plan perimeter of the semiconductor readout/processing substrate falling within the top plan shadow perimeter of the corresponding semiconductor detector substrate with which it electrically communicates. Additionally, all of the readout/processing circuitry contacts of the semiconductor readout/processing substrate are disposed on the surface of the semiconductor readout/processing substrate that electrically communicates with the intermediate substrate. Substantially all electrical communication to and from the semiconductor readout/processing substrate is routed through the intermediate substrate. The intermediate substrate is a printed circuit board or similar construct. The electrical contacts between the semiconductor substrates and the intermediate substrate are accomplished using bump-bonds, conductive adhesive bonds, conductive adhesive films or a combination thereof. One or two dimensional planar arrays of semiconductor readout/processing substrates and corresponding semiconductor detector substrates can be mounted on a single intermediate substrate using “tiling” techniques known in the art to form a mosaic radiation imaging device of increased active imaging area and reduced/minimized imaging dead area.
