A coordinate light source calculating section (103) calculates the three- dimensional coordinates of each of the points forming an object and performs clipping. A rendering section (104) outputs a graphic still picture formed by rendering to a frame buffer (108). The coordinate light source calculating section (103) calculates the three-dimensional coordinates of each of the points forming a moving picture display face. A perspective converting section (105) calculates the two-dimensional coordinates of each of the points forming the moving picture display face. A picture decoding section (106) decodes a video still picture, and a picture transforming section (107) transforms the video still picture and outputs it to a frame buffer (108). Thus, a video still picture is pasted on a graphic still picture.

L'invention concerne une section (103) de calcul de la source de lumière de coordonnées. Cette section calcule les coordonnées en trois dimensions de chacun des points formant un objet et assure la coupure. Une section (104) de rendement émet une image graphique fixe formée par la section de rendement et transmise à un tampon de trames (108). La section (103) de calcul de la source de lumière de coordonnées calcule les coordonnées tridimensionnelles de chacun des points formant une face d'affichage d'images mobiles. Une section de conversion de perspectives (105) calcule les coordonnées en deux dimensions de chacun des points formant la face d'affichage des images mobiles. Une section de décodage d'images (106) décode une image vidéo fixe et une section de transformation des images (107) transforme l'image vidéo fixe et l'envoie dans un tampon de trames (108). Ainsi, une image vidéo fixe est collée sur une image graphique fixe.
