Abstract:
A stereoscopic image generating device for generating a stereoscopic image based on an input video signal, said device comprising:classifying means for respectively classifying said input video signal into index classes on the basis of a level distribution pattern of plural pixels in a first predetermined spatio-temporal region;left eye predictive coefficient storing means for storing plural sets of predictive coefficients for left eye images which correspond to the respective index classes and which have been previously obtained by learning;right eye predictive coefficient storing means for storing plural sets of predictive coefficients for right eye images which correspond to the respective index classes and which have been previously obtained by learning;predictive blocking means for blocking said input video signal for every plural pixels in a second predetermined spatio-temporal region, and for generating predictive block values for predictive calculating;left eye calculating means for generating a left eye video signal by performing a calculation on the basis of a linear primary combination expression; which uses said input video signals, said sets of left eye predictive coefficients obtained from said left eye predictive coefficient storing means in response to the classification results obtained on the basis of the output of said classifying means, and also uses said predictive block values obtained on the basis of the output of said predictive blocking means; andright eye calculating means for generating a right eve video signal by performing a calculation on the basis of a linear primary combination expression; which uses said input video signals, said sets of right eve predictive coefficients obtained from said right eye predictive coefficient storing means in response to the classification results obtained on the basis of the output of said classifying means, and also uses said predictive block values obtained on the basis of the output of said predictive blocking means.
