Abstract:
1. A method for controlling shapes of FM-AM mixed dots on a multi-bit depth imaging apparatus, comprising: 1) dividing averagely an interval [0, 255] into 2 [0, R i is a positive integer and less than 2 n −2, corresponding ranges of a dot-matrix of bit-outputting are (0, Out the Out i being a binary representation of the n-bit depth, and a threshold M 2) setting output probability thresholds with a n-bit imaging depth in the interval [0, 255]; 3) processing respectively the dots in the 2 4) computing dynamically output dot-matrix data, by using a dynamic gradation-changeable output mechanism and a dynamic statistic algorithm with adjacent output gray levels in light of the probability thresholds F
