    • A character and symbol pattern generator includes a skeleton data storage device for storing beforehand, for every skeleton pattern. Skeleton data includes coordinate data of each skeleton point at which changes occur at least in the stroke direction of skeleton pattern for forming characters and symbols, two thickness data which represent lengths of two thickness segments of a stroke on the start and end points of the skeleton pattern, and two angle data which represent angles of the two thickness segments with respect to the stroke direction or the horizontal direction. An input device is used to designate the kind and size of the character and symbol. A thickness data calculating device calculates thickness data of each skeleton point from the two thickness data of the start and end points and the coordinate data of each skeleton point. An angle data calculating device calculates angle data of the thickness segment of each skeleton point from the two angle data of the start and end points and the coordinate data of each skeleton point. An outline data generating device generates outline data from the skeleton data and from the thickness data and the angle data of each skeleton point calculated by the calculating devices respectively. A character and symbol pattern synthesizing device synthesizes character and symbol patterns based on the outline data. An output device outputs the character and symbol patterns.
    • 字符和符号图案生成器包括用于每个骨架图案预先存储的骨架数据存储装置。 骨架数据包括至少在用于形成字符和符号的骨架图案的笔划方向上发生变化的每个骨架点的坐标数据,两个厚度数据,其表示骨架的起点和终点上的笔画的两个厚度段的长度 图案和两个角度数据,其表示两个厚度段相对于行程方向或水平方向的角度。 输入设备用于指定字符和符号的种类和大小。 厚度数据计算装置从起点和终点的两个厚度数据和每个骨架点的坐标数据计算每个骨架点的厚度数据。 角度数据计算装置从起点和终点的两个角度数据和每个骨架点的坐标数据计算每个骨架点的厚度段的角度数据。 轮廓数据生成装置从骨架数据和由计算装置计算出的各骨架点的厚度数据和角度数据分别生成轮廓数据。 字符和符号图案合成装置基于轮廓数据合成字符和符号图案。 输出设备输出字符和符号图案。

    • A character pattern generating apparatus includes a memory and a CPU. The memory stores, in advance, character skeleton data representing the skeleton shapes of characters and element outline data representing the outline shapes of the elements constituting the characters for each character style. The CPU obtains outline shape data corresponding to one constituent element in character skeleton data from the element outline data, extracts therefrom element skeleton data for the constituent element, transforms the extracted element skeleton data based on the character skeleton data, and modifies the outline shape data in accordance with the transformation so as to generate a character pattern by using the modified outline data. The character pattern generating apparatus of the present invention generates multiple kinds of high quality fonts involving no design restrictions in a smaller number of steps.
    • 字符图形生成装置包括存储器和CPU。 存储器预先存储表示字符的骨架形状的字符骨架数据和表示构成每个字符样式的字符的元素的轮廓形状的元素轮廓数据。 CPU从元素轮廓数据中获取与字符骨架数据中的一个构成要素相对应的轮廓形状数据,从构成要素提取元素骨架数据,根据字符骨架数据变换提取的元素骨架数据,并修改轮廓形状数据 根据变换,通过使用修改的轮廓数据来生成字符图案。 本发明的字符图形生成装置在较少数量的步骤中生成不具有设计限制的多种高品质字体。

    • According to a method of the present invention, an optical alphanumeric character reader scans each printed line in the direction of its height from its beginning to its end sequentially at a predetermined interval. The intervals thus scanned are identified either as containing a printed part or as being all white and are represented respectively by a "black bit" and a "white bit" corresponding to different logical numbers. For each white bit or each continuous array of white bits sandwiched between black bits, the number of white bit or bits between the sandwiching black bits is counted. The histogram of such counted numbers has two peaks corresponding to gaps between letters and those between words and serves to determine a threshold value by which a space between words can be detected by the optical character reader.
    • 根据本发明的方法,光学字母数字字符读取器以预定间隔从其开始到其结束的顺序沿其高度的方向扫描每个印刷线。 这样扫描的间隔被识别为包含打印部分或全部为白色,并且分别由对应于不同逻辑数字的“黑色位”和“白色位”表示。 对于夹在黑色位之间的每个白色位或每个连续的白色数组,计数夹入黑色位之间的白色位或位数。 这样计数的直方图具有两个对应于字母之间的间隙和字之间的峰值,并且用于确定通过光学字符读取器可以检测出字之间的间隔的阈值。
