Beschreibung
Zusammenfassung:	This invention discloses an in-frame forecasting method, comprising: obtaining a current block in the frame for pixel value forecasting, determining pixel forecasting value of the current block in current pattern direction according to forecasting mode direction of block adjacent to the current block and/or reference pixel value of the adjacent block. This invention also discloses an in-frame forecasting device. With application of this invention, pattern distribution continuity of current block can be remained during forecasting of pixel value of current block and forecasting precision can be ensured simply and conveniently.
