    • The present invention relates to a method and apparatus capable of generating frequency-modulation halftone dots in high speed and belongs to the field of the digital image halftone. In the prior art, read-write operation is usually carried out many times in error rows during processing each pixel so that halftone dots are generated in low speed. In the method according to the present invention, the error generated by the current pixel is buffered in a register file and the final accumulated error values are written in the error rows only after all of the relative pixels are processed. Thus, read-write operation is carried out only once in the error rows for processing each pixel. The present invention also provides an apparatus to implement the method. The apparatus comprises an error row memory, an error buffer register file, a gray generation circuit, a threshold comparison circuit, an error generation circuit, an error buffer register file control circuit, and an error row control circuit. The method and apparatus according to the present invention decrease the steps in operation and improve the speed for generating the frequency-modulation halftone dots.
    • 本发明涉及能够高速产生调频半色调点的属于数字图像半色调的领域的方法和装置。 在现有技术中,在处理每个像素期间,读写操作通常在错误行中进行多次,使得半色调点以低速生成。 在根据本发明的方法中,由当前像素产生的误差被缓存在寄存器文件中,并且只有在处理了所有相对像素之后才将最终的累积误差值写入误差行。 因此,在用于处理每个像素的错误行中仅执行一次读写操作。 本发明还提供了一种实现该方法的装置。 该装置包括错误行存储器,错误缓冲寄存器文件,灰色生成电路,阈值比较电路,错误产生电路,错误缓冲寄存器文件控制电路和错误行控制电路。 根据本发明的方法和装置降低了操作步骤,提高了生成调频半色调点的速度。
