Abstract: A drawing processing apparatus and method wherein scrolling display which provides no sense of incongruity is achieved in 3D display. 3D information is produced using information in a drawing object range extracted as a predetermined range on map data. The drawing object range of an object of the 3D drawing process is moved in response to a scrolling operation. While the drawing object range is moved, 3D image data are successively produced using the drawing object range at every point of time and outputted to implement 3D display on a display screen. Thereupon, the drawing object range to be used for the 3D drawing is moved such that individual portions in the drawing object range are moved by movement amounts determined with reference to a distance in a perpendicular direction at a reference position in the drawing object range.

Abstract: One-dimensional signals suitable for scrolling or other user interface functions are provided in response to two-dimensional inputs produced by a touchpad or other input device. A current chirality of the two-dimensional inputs is determined to have a first sense if the two-dimensional inputs exhibit a primary clockwise trajectory and a second sense if the two-dimensional inputs exhibit a primarily counter-clockwise trajectory. A one-dimensional variable is accumulated using a magnitude that is a function of a distance reflected by the two-dimensional inputs and a sign that is based upon the current chirality. The one-dimensional inputs to the computing system may then be extracted from the accumulated one-dimensional variable as appropriate. The methods may be modal, thereby allowing the same pointing device to be used for both two-dimensional and one-dimensional input.

Abstract: When scrolling in a vertical direction, field determining means determines whether a field currently being scanned is odd-numbered or even-numbered. Address calculating means decrements a reading address for reading image data from image data storage means in a vertical direction by a given number of lines at the start of scanning of an even-numbered field on the basis of a result of the determination when scrolling in an upward direction and increments the reading address by a given number of lines at the start of scanning of an odd-numbered field when scrolling in a downward direction. The image data storage means sequentially reads the image data for output according to the calculated address.

Abstract: The invention provides a method and apparatus for an anti-aliasing process that allows for super-sampling at a high subpixel resolution, but does not require the process and memory resources typically required for conventional super-sampling at this subpixel resolution. Each pixel is partitioned into an array that provides for a large number of subpixels, and a smaller set of super-samples from this set of subpixels are sampled and used to determine the resultant pixel values. Because the set of super-samples is substantially smaller in number (less than half) than the number of subpixels, the processing and memory requirements are substantially reduced. The set of super-samples are preferably determined so as to provide for a uniform sampling frequency in each of the major axes, and along each diagonal, even though the super-samples may not provide an uniform sampling of each pixel area.
