摘要： A scanning beam display system includes an optical module, an image control module, and a display screen on which optical beams are scanned. The optical module includes a vertical adjuster placed in the optical paths of the beams to control and adjust positions of the optical beams along a generally vertical direction on the display screen, and a control unit configured to receive control instructions for the vertical adjuster and to control the vertical adjuster to be at one of a predetermined number of orientations to place the scanning optical beams at a corresponding distinct position on the display screen. The control unit is further configured to apply an adjustment offset to each orientation of the vertical adjuster such that each immediately vertically adjacent pair of beam footprints projected on the display screen resulting from the plurality of positions have a vertical overlap that is larger than a first threshold.

摘要： A method, system, and computer-readable storage medium are disclosed for simulating bristle brush behavior in an image editing application. User input may represent a stroke made by a paintbrush comprising multiple bristles sweeping across a canvas. The application may calculate a per-bristle opacity value using an exponential function dependent on a target opacity value for the brush stroke and an expected number of overlapping bristles during the brush stroke. The per-bristle opacity value may be used to determine per-bristle effects of the deposition of paint on the color and/or opacity values of the canvas pixels affected by the brush stroke as these per-bristle effects are composited to determine the cumulative effect of the brush stroke. The per-bristle opacity value may be calculated based on the brush orientation or position, direction of the stroke, number of bristles, type or shape of the brush tool, and/or pressure applied to the brush tool.

摘要： An image processing apparatus for automatically improving the contrast of an input image that is obtained from a digital camera or the like, and obtaining a sharper and clearing image. A contrast improvement unit (11) performs a contrast improvement process on the input image by comparing an object pixel in the input image with pixels in the surrounding area. An image combination unit (12) combines the enhanced image obtained by the contrast improvement process with the input image.

摘要： The present invention provides an inexpensive projection display that allows a pixel grid as ineffective portions of respective pixels of a light valve to be made inconspicuous. The projection display includes a birefringent element (43) for spatially separating light from a transmission liquid crystal light valve (39). The birefringent element (43) includes a first birefringent plate (40) that the light from the liquid crystal light valve (39) enters, a second birefringent plate (41) that light from the first birefringent plate (40) enters, and a third birefringent plate (42) that light from the second birefringent plate (41) enters. A polarization direction of the light entering the first birefringent plate (40) forms an angle of n×45° (n is an integer other than 0) with an optic axis of the first birefringent plate (40) projected on an incident surface of the first birefringent plate (40). An optic axis of the second birefringent plate (41) projected on an incident surface of the second birefringent plate (41) is orthogonal to the optic axis of the first birefringent plate (40) projected on the incident surface of the first birefringent plate (40). An optic axis of the third birefringent plate (42) projected on an incident surface of the third birefringent plate (42) extends horizontally or vertically.

摘要： Computer implemented methods and systems for CAD data exchange, and in particular for creating boundary representations (“breps”) on a feature-by-feature basis are disclosed. According to an embodiment of the techniques described herein, a parameterized feature from a parametric based design system is exported from a source CAD system (404). Iterative steps and complimentary extraction techniques are employed by one or more processors (452, 456) to create an importable design model of the parameterized feature (433), which is imported into a target CAD system (408). While the techniques can include API (436), pattern matching (440), and user emulation (444) techniques, they include a brep per feature (450) technique. By exporting the brep on a per feature (453) basis from the source CAD system (404), the design intent of a CAD designer can be preserved on importation into the target CAD system (408). In particular, where a parametric representation (433) of the feature fails to import into the target system (408), an unparameterized representation (453) of the feature can be substituted.
