    • For each pel signal capable of taking each of a plurality of levels with a first probability dependent on a reference signal, binary prediction error codes are produced to represent one of serial numbers assigned to the first probabilities arranged in a monotonously decreasing order that is coincident with the actually taken level. Mode codes are allotted to the respective prediction error codes with each mode code made to represent a second probability that the prediction error code allotted therewith is binary zero. The prediction error codes for a sequence of pel signals are grouped according to the mode codes allotted thereto and then compression encoded. Preferably, the mode codes are produced in consideration of the prediction error code or codes of more significant binary bit. A compression encoded signal is expansion decoded by alternatingly reproducing the mode codes and the prediction error codes. Reproductions of the prediction error codes provide reproduced pel signals. When the pel signal is variable among a great number of levels, the pel signal is preferably represented by a combination of one each of a plurality of partial pel signals, each representative of a smaller number of levels.
    • 对于能够以取决于参考信号的第一概率获取多个级别中的每个级别的每个像素信号,产生二进制预测错误代码,以表示分配给以与单独递减的顺序排列的第一概率的序列号 实际取得的水平。 将模式码分配给相应的预测误差码,每个模式码用于表示其分配的预测误差码为二进制零的第二概率。 根据分配给其的模式码对像素信号序列的预测误差码进行分组,然后进行压缩编码。 优选地,考虑到预测误差代码或更重要的二进制位的代码来产生模式代码。 通过交替地再现模式码和预测误差码来对压缩编码信号进行扩展解码。 预测误差代码的复制提供了再现的像素信号。 当像素信号在大量电平之间是可变的时,像素信号优选地由多个部分像素信号中的每一个的组合来表示,每个代表较小数量的电平。

    • For selectively carrying out predictive encoding of an original pattern of a first tone on a background of a second tone and a thinned pattern having, in effect, the first tone on its background corresponding to the second tone, a device comprises a predictor responsive to a set of sample pulses representative of a few picture elements selected from those sampled from the original pattern and its background for producing each of prediction error pulses of a sequence, another predictor responsive to a set of pre-processed pulses representative of several picture elements selected from those sampled, in effect, from the thinned pattern and its background for producing each of error pulses of another sequence, a selector for selecting one of the original and the thinned patterns and consequently one of the predictors to produce a selection code indicative of the selected predictor, and an encoder for encoding the error pulses produced by the selected predictor into an encoded signal including the selection code. Preferably, each predictor is operable to produce for each error pulse a mode code indicative of one of two or more groups into which all allowable permutations of at least one of the two tones of the selected picture elements are classified and, in comsideration of which, codes are predetermined for all possible durations of same error pulse. The encoder uses the mode code for the respective error pulses in selecting some or all of the predetermined codes and arranges the selected codes in a predetermined order.
