Abstract

A picture information converting apparatus for generating a plurality of output picture signals. The apparatus includes first data selecting means; second data selecting means; memory means for storing a pre-obtained estimation expression coefficient; pixel value generating means for generating the first pixel with the second pixels selected by the first data selecting means and a linear estimation expression of the estimation expression coefficient; class determining means for generating class information corresponding to the third pixels selected by the second data selecting means and supplying the estimation expression coefficient to the pixel value generating means corresponding to the class information; scanning line structure converting means, connected to the pixel value generating means, for converting a conversion picture to a designated scanning line structure; and controlling means for receiving a control signal that designates a scanning line structure of the output picture signal and for switching over at least one of the estimation expression coefficient, the second pixels selected by the first data selecting means and the third pixels selected by the second data sele…
