An ultra-thin digital imaging device has a thickness of several millimeters and is capable of producing data for creating images of 3 Mp and higher. The device comprises a multi-channel imaging unit that contains a plurality of optical channels formed by microlens objectives and a pixilated image sensor unit with a plurality of sensing elements. Each individual identical image obtained through each optical channel is pixilated and converted into electrical signals that are processed into data sets which can be stored in the imaging device and either reproduced on the display of the device or transmitted to an external image-reproducing device where the obtained data of individual images are transformed into a single, high-resolution megapixel image by means of a technique known in the art.

A projection display system includes a projection lens assembly that has multiple projection lens elements that are configured to receive light imparted with display information by a pixelated display device. The projection lens elements project the light toward a display screen. A pixel-shifting element is included within the projection lens assembly to cyclically shift between at least two positions within the projection lens assembly to form at a display screen at least two interlaced arrays of pixels. An electromechanical transducer is coupled to the pixel-shifting element to impart on it the cyclic shifting between positions.

A method and system are disclosed for creating a real-time, high accuracy mosaic from an aerial video image stream by applying orthorectification of each original video image frame using known ground control points, utilizing a photogrammetric model resolving the object image into pixilation, applying shading to the pixellation, and mosaicking the shaded pixilation of several orthorectified images into a mosaicked image where the mosaicked image is then scaled to the known original image dimensions.

A drawing processing apparatus capable of executing a drawing processing program having conditional branches efficiently by multipass rendering. The drawing processing apparatus comprises arithmetic processing parts including an object input part, a primitive generating part, a raster part, a pixelation part, a distribution part, and a shader which constitute pipeline stages. The shader divides the program into and executes the same in a plurality of passes depending on conditional branches. The shader generates enable flags determining whether or not respective pixels satisfy branch conditions. The flag generating part generates bind enable flags which are the enable flags on the pixels bound into the processing granularities of the pipeline stages, and feeds back the same to the respective pipeline stages. The arithmetic processing parts in the individual pipeline stages refer to the bind enable flags and limit the submission of data not targeted for arithmetic processing in the branched passes.

A collimator for collimating high-energy photons, which may be used in medical imaging (e.g., nuclear medicine). The collimator has holes through the thickness (height) of the collimator, with the holes arranged in groups or clusters. The collimator may be used with a detector having an array of pixels, wherein each group of holes may be associated with a corresponding pixel, thereby providing multiple collimator holes per pixel. In one embodiment, each group of holes has septa of a given width separating the holes in that group, and each group of holes is separated from neighboring groups by septa of another, greater width. In another embodiment, the intra-group septa may be recessed from the top and/or bottom surface(s) of the collimator such that these septa have a smaller thickness (height) than the inter-group septa.

A multi-view display device comprises a pixellated display panel and a backlight comprising an arrangement of light sources (30), wherein each light source, when turned on, illuminates an associated region of pixels of the display panel. A display controller is adapted to control the pixellated display panel and the arrangement of light sources such that a partial display output is provided comprising simultaneously a set of at least three 2D views with no repetition of individual 2D views. This arrangement provides an output with controlled illumination direction of the pixels so that view repetitions are avoided. The output can be a single cone of views, and the location from which the cone of views can be viewed depends on the relationship between the light sources of the backlight which are activated and the display panel.

Borehole image data is compressed and transmitted to the surface one pixilated trace at a time. The compression methodology typically includes transform, quantization, and entropy encoding steps. The invention advantageously provides for sufficient data compression to enable conventional telemetry techniques (e.g., mud pulse telemetry) to be utilized for transmitting borehole images to the surface. By compressing and transmitting sensor data trace by trace the invention also tends to significantly reduce latency.

An LCD panel employing a novel scheme of systemic light recycling. A single polarization state of light is transmitted from the backlighting structure to section of the LCD panel where both spatial intensity and spectral filtering of the transmitted polarized light simultaneously occurs on a subpixel basis. At each subpixel location, spectral bands of light not transmitted to the display surface during spectral filtering, are reflected without absorption back along the projection axis into the backlighting structure. At a subcomponent level within the LCD panel, spectral components of transmitted polarized light not used at any particular subpixel structure location are effectively reflected either directly or indirectly back into the backlighting structure.

An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a hexagonal grid, and the lenses also repeat in a hexagonal grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimensional space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

An illumination panel for illuminating an object, comprising a substrate, a light diffractive grating and a light source. The substrate is made from an optically transparent material having first and second area surfaces disposed substantially parallel to each other and a light input surface for conducting a light beam into the substrate. The light diffractive grating is mounted to the first areal surface and has a slanted fringe structure embodied therein for diffracting the light beam falling incident thereto, along a first diffractive order of the slanted fringe structure. The light source produces a light beam for transmission through the input surface and direct passage through the substrate to the slanted fringe structure so as to produce an output light beam of areal extent that emerges from either the first or second areal surface along the first diffractive order, for use in illuminating an object. A spatial-intensity modulation panel can be mounted to the illumination panel to form a color image display device. In the illustrative embodiments, the light diffractive grating is a volume hologram that is pixelated and spectrally-tuned in order to carry out spectral filtering functions within the color image display device.

A color display system includes a color light separator that separates incident white illumination light into red, green and blue wavelength bands to be directed to distinct color component sub-pixels (sometimes called dots) that are arranged in a dot-matrix, color triad arrangement (e.g., stripe or delta) to form individual picture elements (pixels) on a pixelated electronic image device (e.g., LCD of DMD). The entire picture is optically shifted from one set of color component sub-pixels to another in a 3-field sequence. As a result, the sets of red, green and blue color component sub-pixels appear to an observer as a single full-color image, thereby providing a dot sequential color display.

Aligning a cut-to-size (off-wafer) pixilated micro-grid polarizer to a ready packaged imaging sensor having multiple pixels involves minimizing a separation distance between the two units and then aligning respective corresponding pixels of the pixilated micro-grid polarizer with the pixels of the imaging sensor using optical signals as position feedback during the alignment process. Once the alignment has been achieved, the micro-grid polarizer may be affixed to the imaging sensor, for example using optical epoxy glue.

An optical comparator arranged for rear projection onto a viewing screen combines an optical projector that projects an optical image of a test part under inspection onto the viewing screen with a video projector that projects an optical image of a pixilated template pattern containing illustrated specifications of the test part onto the same viewing screen. The images of the test part and the pixilated template pattern are projected concurrently onto the viewing screen for visually comparing the form of the test part against its specified form.

Several systems and associated methodologies are provided for rendering a themed image while mitigating pixelation and/or the disproportionate appearance thereof when the image is sized and/or scaled. The systems include at least one sizing module adapted to size components of a themed UI element. The systems also include at least one alignment module adapted to align at least one second component of a UI element within a first component of a UI element. The sizing modules are adapted to size the components with nine grid methodologies or based upon the ratio of the DPI of the context that the UI element is being rendered to the DPI that at least one of the components was designed under.

Generating a high definition projected illumination pattern from a substantially lower resolution digital projector array involves: selectively illuminating a connected set of pixels to produce a pixellated, high contrast edge feature, and positioning an anisotropically blurring optical element (ABOE) between a light source of the projector array and the projection. The ABOE applies an anisotropic blur pattern to pixels of the at least one connected set, to locally preferentially blur the pixel more (and preferably substantially only) in a direction of equally or more strongly illuminated pixels, and not in directions of less illuminated pixels. Preferably a contour of the connected set has no beginning or end within a periphery of the illumination plane, and has bounded curvature, permitting simple ABOEs to be used. Several images each having several or many edges can be produced using a same ABOE. The ABOE may alleviate interpixel gap effects for non-edge pixels too.
