CA 2313178

An image special effect of making near objects sharp and far objects unsharp on a screen is readily produced. On a screen (200), an image (156a'') concerning far objects of relative large depth including the background is formed by performing a semitransparency processing of shifting the original image by two pixels upward, an image (154a') concerning middle distant objects is formed by performing a semitransparency processing of shifting the original image by one pixel upward, and an image (152a) concerning near objects is formed without performing any such upward shifting processing. In such an image (222) thus formed, the near image (152a) is sharp, the middle distant image (154a') is a little unsharp, and the far image (156a'') is more unsharp.

Selon l'invention, un effet spécial permettant de rendre nets des objets proches et de rendre flous des objets éloignés, sur un écran, peut être facilement produit. Une image (156a'') affichée sur un écran (200), représentant des objets éloignés d'un profondeur relativement importante, y compris l'arrière-plan, est formée au moyen d'un traitement de semitransparence, consistant à décaler l'image originale de deux pixels vers le haut. Une image (154a') représentant des objets placés à une distance moyenne, est formée par un traitement de semitransparence, consistant à décaler l'image originale d'un pixel vers le haut. Enfin, une image (152a) représentant des objets proches, est formée sans traitement de décalage vers le haut. Dans une image (222) ainsi formée, l'image d'objets proches (152a) est nette, l'image d'objets à distance moyenne (154a') est légèrement floue, et l'image d'objets éloignés (156a'') est plus floue que cette dernière.
