    • A system is provided for generating transition effects for use on a visual display. The system includes a binary table for describing a transition effect and a method for ordering the rows in the table to produce the transition. The table includes an arbitrary number of rows, each row representing a cell (group of picture elements) on the display. A numerical value, based on any function of cell location, is associated with each cell. The table is then sorted according to the numerical values. Each row in the sorted table drives a step in the transition effect. The cells described by the various rows are changed in sorted order to display the material from the image being transitioned-to. The sequence of processing of the rows causes the desired transition effect. By varying the function used to order the rows, an infinite variety of transition effects can be created.
    • 提供了一种用于产生在视觉显示器上使用的过渡效果的系统。 该系统包括用于描述转换效果的二进制表和用于排序表中的行以产生转换的方法。 该表包括任意数量的行,每行表示显示器上的一个单元格(图像元素组)。 基于单元格位置的任何函数的数值与每个单元格相关联。 然后根据数值对表进行排序。 排序表中的每一行都会驱动转换效果的一个步骤。 由各行描述的单元格按照排序顺序进行更改,以显示正在转换的图像中的材质。 行的处理顺序会产生所需的过渡效果。 通过改变用于排列行的功能,可以创建无限多种过渡效果。

    • Method and apparatus for generating relative movement between a first image and a second image while avoiding display screen flicker. The method includes a step of copying to a first buffer a portion of a display memory corresponding to a present portion of the second image wherein a first image will first appear. The method further includes the steps of superimposing within the display memory the first image upon the present portion of the second image and copying to a second buffer the portion of the display memory corresponding to the present portion of the second image, including the first image superimposed thereon, and a portion of the display memory corresponding to a next portion of the second image wherein the first image will next appear. The method further includes the steps of erasing the first image from the second buffer by copying the present portion from the first buffer to the second buffer and superimposing, within the second buffer, the first image upon the next portion of the second image. The method includes a further step of copying the second buffer to the display memory such that the first image disappears from the present portion of the second image while simultaneously appearing within the next portion of the second image, thereby avoiding display screen flicker.
