    • Halftoning apparatus and method that may generate and employ average values and shifts are described herein. The apparatus may include an unpacker to determine shifts and average values for a plurality of input pixel values, each pair of average value and shift being associated with a corresponding pair of the input pixel values. The apparatus may further include a halftone core coupled to the unpacker to receive the shifts and the average values from the unpacker and to generate pairs of output pixel values based at least in part on the received shifts and average values, wherein the output pixel values are for generating pixels of an image.
    • 这里描述了可产生和应用平均值和偏移的半色调装置和方法。 该装置可以包括解包器以确定多个输入像素值的移位和平均值,每对平均值和移位与相应的一对输入像素值相关联。 该装置还可以包括耦合到解包器的半色调网络,以至少部分地基于接收到的移位和平均值来接收来自解包器的移位和平均值,并产生输出像素值对,其中输出像素值为 用于生成图像的像素。
