    • In order to provide a presentation system for displaying various kinds of media data simultaneously on a display device of any resolution, a scenario description file is prepared in the invention for storing information concerning media data to be presented. A presentation system of the invention comprises an initial information table analyzing section and media information table analyzing section for analyzing the scenario description file, a layout correcting section for correcting positional information and sizes of display images of display media data described in the scenario description file, according to the resolution difference between the display device employed in editing the scenario description file and that for presentation, together with a font preparing section for correcting character sizes and character thicknesses, and a time description correcting section for correcting a reproduction time error caused by correcting the display sizes of the media data.

    • A method of setting threshold values for extracting image data includes the steps of determining (a) that a pixel of an image to be extracted is to be displayed in color if (1) a density value of the pixel is between a first threshold value and a second threshold value, and (2) a density gradient of the pixel is between a third threshold value and a fourth threshold value, and (b) that the pixel is to be displayed in monochrome if (1) the density value of the pixel is not between the first threshold value and the second threshold value, or (2) the density gradient of the pixel is not between the third threshold value and the fourth threshold value, and changing at least one of the first threshold value and the second threshold value to enable a desired image region of the image to be extracted to be displayed in color.
    • 设置提取图像数据的阈值的方法包括以下步骤:(a)如果(1)像素的浓度值在第一阈值和第二阈值之间,则要提取的图像的像素将被显示为彩色的步骤 第二阈值,和(2)像素的浓度梯度在第三阈值和第四阈值之间,并且(b)如果(1)像素的浓度值,则像素将以单色显示 不在第一阈值和第二阈值之间,或者(2)像素的浓度梯度不在第三阈值和第四阈值之间,并且改变第一阈值和第二阈值中的至少一个 值以使图像的期望图像区域被提取以被显示为彩色。

    • An image process is performed using a computer, without needing any special knowledge by a user. First, when a picture on a screen is designated and inputted by an input unit, a check is made to determine if an input figure name corresponding to the input figure is defined in a first table stored in a memory. When it is judged that the input figure name is defined, a setting method of a value of a variable in the first table is determined. On the basis of the determined setting method, the value is set into the variable shown by the variable name in the first table. A check is made to determine if a figure shown by a connected figure name which is defined in a second table stored in the same memory as that of the first table, and is interlocked with the variable shown by the variable name exists on a screen. When it is judged that such a figure exists, the figure shown by the connected figure name is edited and displayed on the basis of the display type in the second table.
    • 使用计算机执行图像处理,而不需要用户的任何特殊知识。 首先,当通过输入单元指定并输入屏幕上的图片时,进行检查以确定在存储在存储器中的第一表中是否定义了与输入图形相对应的输入图形名称。 当判定输入图形名称被定义时,确定第一表中的变量的值的设定方法。 在确定的设置方法的基础上,将该值设置为第一个表中变量名所示的变量。 进行检查以确定在与存储在与第一表相同的存储器中的第二表中定义的连接图名称所示的图形是否与变量名称所示的变量互锁在屏幕上。 当判断出这样的图形时,根据第二表中的显示类型编辑并显示所连接的图形名称所示的图形。
