Abstract: Control and output-quality variables of a process plant (1) are plotted against parallel axes in a display unit (7). Convex hulls between pairs of variables are calculated from sets of the variable-values accumulated historically in stores (7, 9) during successive runs of the process, and hulls (HH; TC, BC) between successive axis-pairs are displayed. New variable-values for process optimization are fixed for the variables taken in turn, each selection being made within displayed ranges (Rn—Rn) derived from the hulls effective between the respective variable and the variables already fixed. A display unit (13) provides on-line parallel-axis display of variable-values from the plant (1), showing alarm carets (DC, UC) where values violate limits (UL, LL) determined by the convex hulls, and allowing variation in the displayed-value for observing the resultant effect in avoiding alarm situation and towards optimization.

Abstract: There is provided a multi-sync type of display apparatus that enables changes in input signals to be accurately determined while increasing the accuracy when identifying input synchronization signals. When input synchronization signals Wa are within a predetermined phase difference, a pseudo synchronization signal generation apparatus formed by a frequency detection section 7 and a pseudo synchronization signal generation section 8 generates pseudo synchronization signals Wd that are synchronized with the input synchronization signals Wa. If the input synchronization signals Wa exceed a predetermined phase difference, pseudo synchronization signals Wd that have the frequency of the synchronization signal directly before the input synchronization signals Wa are generated. A phase comparison section 9 compares the pseudo synchronization signals Wd and the input synchronization signals Wa, and outputs comparison result signals when the phase difference exceeds a predetermined phase difference.

Abstract: Disclosed is a method for converting an input digital color image having a set of possible input colors to an output digital color image having a set of palette colors, the number of palette colors being less than the number of possible input colors, wherein the set of palette colors is determined based on the distribution of colors in the input digital image boosted by a distribution of important colors contained in the input digital image.

Abstract: A method for creating a rendered scene that is composed of two or more RGB image layers that can be composited at a later time. The resulting composition will appear the same as if it were rendered all at the same time. The elements of a foreground image layer scene are rendered separately over a black background and a white background. The RGB components for each pixel of the foreground image layer scene rendered over the black background are combined with the RGB components for each corresponding pixel of the foreground image layer scene rendered over the white background to form a rendered foreground layer. The foreground layer may be combined with a background image layer in a conventional manner, possibly with additional material added between the background and foreground image layers.

The digital negative is operated upon based upon a first edit list to form the composited digital image at the original resolution which is then rasterized to form the composited digital image at the first resolution. A second edit list based upon the rasterizing is then generated and the first and second edit lists are then associated with to the composited digital image at the first resolution and linked to the digital negative.

Abstract: It is an objective to provide a image generating system and program capable of performing an environment mapping which can accurately represent the reflection of light source and the like. An environment texture to be viewed in an upward direction from an object is mapped onto the object in a direction toward the object from above the object without depending on the position or rotational angle of a virtual camera. A rotation matrix obtained from the rotational angle of the object about an axis in the world coordinate system is used to rotate the normal vector of the object. The coordinates NXW and NZW of the rotated normal vector are then used to obtain coordinates U and V. Another rotation matrix for transforming the local coordinate system to a coordinate system (XW, ZW, YW) may be used.

Abstract: A graphics to be edited is displayed on a display device and an operator controls a mouse to input coordinate data of two or more points. It is determined whether the curve included in the graphics should be deleted or a new curve should be added, depending on whether inputted coordinate data of two or more points conforms to points on any one of curves included in the graphics to be edited. When it is determined that the curve should be deleted, a deleting curve is generated, and when it is determined that the new curve should be added, an adding curve is generated, and the resultant is superimposed on the editing graphics and is displayed on the display device. When the operator inputs a defined operation, the graphics is corrected based on the deleting curve or the adding curve.

Abstract: A method for determining and assigning colorimetry and authorship device information to an image of unknown colorimetry includes iteratively displaying the image on a display device and selecting possible source device profiles for transforming the image. When a possible source device is indicated or selected, the source device is emulated on the display device and the image is displayed through the emulation. A user can then evaluate the indicated source device and if necessary indicate a new possible source device. When the most likely source device is selected, further image processing is enabled. The method can be carried out on a color image processor comprising a source device emulator and display device interface. The display device interface can use a display device profile for profile connection space to display device transformation.
