Abstract
(EN)
In cases when a drawn image is formed in stereographic video to be displayed in an i-th frame period of a plurality of frame periods in the playback time axis of a video stream, it is necessary to complete writing of the drawn image to a left view plane memory and writing of the drawn image to a right view plane memory before the i-th frame period begins. In order to simultaneously issue instructions for this writing, the parameters of the application program interface include a pair of designations which comprise a write designation to the left view plane memory and a write designation to the right view plane memory.

Selon l'invention, dans les cas où une image étirée est formée dans une vidéo stéréographique pour être affichée dans une i-ième période de trame d'une pluralité de périodes de trame dans l'axe temporel de lecture d'un flux vidéo, il est nécessaire d'achever l'écriture de l'image étirée sur une mémoire de plan de vision gauche et l'écriture de l'image étirée sur une mémoire de plan de vision droite avant le début de la i-ième période de trame. Dans le but de sortir simultanément les instructions pour cette écriture, les paramètres de l'interface de programme d'application contiennent une paire de désignations qui comprend une désignation d'écriture sur la mémoire de plan de vision gauche et une désignation d'écriture sur la mémoire de plan de vision droite.

 ビデオストリームの再生時間軸における複数のフレーム期間のうち、i番目のフレーム期間において表示されるべき立体視映像に描画イメージを合成する場合、i番目のフレーム期間が開始されるまでに、レフトビュープレーンメモリへの描画イメージの書き込み、及び、ライトビュープレーンメモリへの描画イメージの書き込みを完了する必要がある。この書き込みの指示を同時に命じるべく、アプリケーションプログラムインターフェイスの引数は、レフトビュープレーンメモリへの書き込み指定と、ライトビュープレーンメモリへの書き込み指定とのペアを含む。
