    • Bitmapped graphics, font and vector form figure are transformed to gradation value respectively by zooming means (1), font representing means (2) and vector representing means (3). They are inputted to figure conserving gradation pixel data generating means (11), where average gradation value of plural gradation values is made and each of bits is given to each of plural gradation values. These bits represent the figure of graphics. So, they are called figure bits or figure data. With appending these figure bits to the average gradation value, generated is a figure conserving gradation pixel data which represents a pixel with high resolution.
    • 位图图形,字体和矢量图形分别通过缩放装置(1),字体表示装置(2)和矢量表示装置(3)分别变换为灰度值。 它们被输入到图形保存灰度像素数据产生装置(11),其中进行多个灰度值的平均灰度值,并且对于多个灰度值中的每一个赋予每个比特。 这些位表示图形。 因此,它们被称为图形位或图形数据。 通过将这些图形位附加到平均灰度值,生成代表具有高分辨率的像素的图形保存灰度像素数据。

    • Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The first signal is transmitted to the LED head in the form of a real printing data signal that is to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing another data sequence, and then stored in a line buffer. The second signal stored in the line buffer is transmitted to the LED head in the form of a real printing data signal that is to be printed on an additional raster line in synchronism with an additional line timing signal. The LED head drive energy with which the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other. The LED head may be provided with such a resolution function.
    • 接收到的视频信号的位数据被部分地转换成表示与LED头的分辨率对应的数据序列的第一信号。 第一信号以与线路定时信号同步的要打印在基本光栅线上的实际打印数据信号的形式发送到LED头。 未转换为第一信号的接收到的视频信号的剩余位数据被转换为表示另一数据序列的第二信号,然后存储在行缓冲器中。 存储在行缓冲器中的第二信号以与附加线路定时信号同步的要打印在附加光栅线上的实际打印数据信号的形式发送到LED头。 基本光栅线被印刷的LED头驱动能量和附加光栅线被印刷的另一个LED头驱动能量彼此独立地设置。 LED头可以具有这样的分辨率功能。
