Abstract: A drawing apparatus includes a CPU. Target image data is written to a drawing area of an SDRAM, and the CPU performs resolution changing processing in a descending direction on the image data of the drawing area.

Abstract: According to embodiments of the invention, rays may be stochastically culled before they are issued into the three-dimensional scene. Stochastically culling rays may reduce the number of rays which need to be traced by the image processing system.

According to another embodiment of the invention, the realism of images rendered by the image processing system may also be improved by stochastically adding secondary rays after ray-primitive intersections have occurred.

Abstract: To provide a CAD-system projection method for a further improvement in user convenience by preventing unnecessary dimension lines from being added when a projection drawing is created from a three-dimensional model. A pre-projected projection drawing is used to set, as objects to be projected, a three-dimensional element of a component in an edit state and a scale line added to the three-dimensional line, the three-dimensional element being a projection source of a two-dimensional element in the projection drawing. Thus, a three-dimensional element that is not in the edit state, a dimension line therefore, and a three-dimensional element that is not a projection source of the two-dimensional element in the projection drawing, and a scale line for the three-dimensional line are not projected. Consequently, it is possible to obtain a projection drawing that includes necessary projection lines and a dimension line therefore.

The one cluster is moved to reorient the cluster's center at the perspective-corrected distance in the display.

A two-dimensional gas chromatography is carried out, during which a chromatographic signal is recorded. A chromatogram in two dimensions on which chromatographic peaks form spots is generated from the signal. These spots are defined by means of polygons. Then, for each polygon, chromatographic signal portions contained between two intersections of the polygon with columns of the chromatogram are extracted. Start and end times are defined for the chromatographic peaks present in these portions and the polygon is adjusted by shifting its intersection points according to the start and end times of the chromatographic peaks. Finally, molecular compound amounts are determined by calculating the surface area of the polygons thus adjusted.

Abstract: From fast moving objects in a video image sequence may appear slightly blurred. A multi-display system including two liquid crystal displays (LCDs) viewed simultaneously via a beam combiner reduces motion blur. The displays operate in time sequential relation, e.g., by alternately and sequentially displaying an image on one LCD while blanking the other LCD and vice versa, by alternately and sequentially turning on and off respective light sources illuminating the LCDs, or by both the foregoing. Alternate sequencing also can be achieved using active shutter glasses to distinguish images for viewing based on optical polarization, possibly with a delay to allow time for image stabilization. Another approach alternates displaying odd lines on a first LCD while blanking even lines and vice versa for the second LCD; and then switching to display even lines on the first LCD while blanking odd lines and vice versa for the second LCD.
