1. a kind of picture decoding apparatus, it is characterised in thatPossesses frame intra-prediction unit, the frame intra-prediction unit is frame in-line coding mould in the coding mode relevant with encoding blockIn the case of formula, each block for the unit that the prediction for becoming the encoding block is processed implements intra-prediction process to generatePrognostic chart picture,The frame intra-prediction unit frame in portion Prediction Parameters represent vertical direction prediction process in the case of, to described pieceAbove the signal value of adjoined pixel, is added the signal value changes of the vertical direction of the pixel that the left side with described piece adjoinsThe proportional value of amount, predictive value of the value after this is added as the prognostic chart picture.
