    • A method for forming images composed of a matrix of dots in a printer, such as a laser printer or an LED printer, and a bit map display unit such as a CRT display, and more particularly a method for smoothing images by smoothing stairsteps included in the images to obtain a high resolution image. The method includes dividing a pixel into a plurality of subpixels along a vertical scanning line or a horizontal scanning line, and reversing a signal for a subpixel following a reversion signal to smooth the image as desired. The reversion signal may be provided by subjecting a specific pixel to a boolean operation, conjunction or disjunction, with the adjacent pixels next to the specific pixel. The reversion signal may also be provided by the steps of: generating, in advance, a set of four bordering data which represents the relationship of a specific pixel with bordering pixels, of which bordering data are generated by subjecting the specific pixel and the four bordering pixels to nonequivalent boolean operation respectively, detecting the location of the stairstep and recognizing the style of the stairstep referring to a relationship among the bordering data for the pixels located along the vertical or horizontal line, and measuring the length of the level pixels adjoining with the stairstep.
    • 一种用于在诸如激光打印机或LED打印机的打印机中形成由点矩阵组成的图像的方法,以及诸如CRT显示器的位图显示单元,更具体地,涉及一种通过平滑图像的平滑方法,包括 图像获得高分辨率图像。 该方法包括沿着垂直扫描线或水平扫描线将像素划分为多个子像素,并且按照反转信号反转子像素的信号以根据需要平滑图像。 可以通过使特定像素与特定像素旁边的相邻像素进行布尔运算,结合或分离来提供反转信号。 还可以通过以下步骤提供反转信号:预先产生一组四个边界数据,该四个边界数据表示特定像素与边界像素的关系,其边界数据通过对特定像素和四个边界进行处理而产生 像素到非等价布尔运算,检测stairstep的位置并识别stairstep的风格,参考位于沿垂直或水平线的像素的边界数据之间的关系,以及测量与 步态
