Abstract

An adaptive predictive encoding apparatus generates predictive values P.sub.1, P.sub.2, . . . , P.sub.n with respect to a quantized value X of a picture element x. Predictive error signals Y.sub.1, Y.sub.2, . . . , Y.sub.n are obtained from the quantized value X and the predictive values P.sub.1, P.sub.2, . . . , P.sub.n. A prediction selection circuit determines the number of mis-predictions from each of the predictive error signals for scanned picture elements. A selection signal M is produced indicating the prediction error signal Y with the least number of mis-predictions, the selection signal controlling a selector to provide the prediction error signal Y in response to the selection signal M. The selected predictive error signal Y is encoded to produce an encoded signal. An adaptive predictive decoding apparatus which decodes the encoded selected predictive error signal is also disclosed.
