Abstract:
The present application discloses a method and an apparatus for generating multi-bit depth halftone amplitude-modulation dots. The method may comprise: scanning an input image to obtain a value of a current pixel Pxy, where x represents a lateral position index of the current pixel, and y represents a vertical position index of the current pixel; obtaining gj from a preset multi-bit depth threshold matrix G by starting with i=0, and determining if Pxy
