Nouvelle API pour l'appareil photo d'Android Lollipop.<\/figcaption><\/figure>\n
Une nouveaut\u00e9 d\u2019Android 5.0 Lollipop qui va permettre d\u2019\u00e9tendre les possibilit\u00e9s de post-traitement <\/strong>des images tout en tirant le meilleur parti des clich\u00e9s gr\u00e2ce au format DNG qui offre une meilleure dynamique et une suppression du bruit notable en comparaison avec le format JPEG.<\/p>\n
Les nouvelles API de l\u2019appareil photo d\u2019Android 5.0 Lollipop<\/strong> modifient la matrice de correction des couleurs et permettent d\u2019acc\u00e9l\u00e9rer la vitesse de capture en mode rafale. Gr\u00e2ce \u00e0 cette nouvelle API, le capteur photo 8 Megapixels du Nexus 5 (dont la mise \u00e0 jour Lollipop<\/a> est pr\u00e9vue pour d\u00e9but novembre) est d\u00e9sormais capable de capturer 30 images par seconde<\/strong> en mode rafale soit plus vite que la plupart des capteurs photos.<\/p>\n
Mais le plus gros des apports de la nouvelle API d\u2019Android 5.0 Lollipop<\/a> d\u00e9di\u00e9e \u00e0 l\u2019appareil photo se situe dans le nouveau format de sortie DNG. Un format brut qui \u00e0 contrario du JPG offre des images sans perte de qualit\u00e9<\/strong> aucune. Selon la nature de l\u2019image, les diff\u00e9rences seront plus ou moins marqu\u00e9es, n\u00e9anmoins, le gain de qualit\u00e9 est bien pr\u00e9sent.<\/p>\n
Afin de mieux appr\u00e9hender les apports du format de sortie DNG<\/strong> face au format JPG, le site am\u00e9ricain Phonearena a r\u00e9alis\u00e9 une s\u00e9rie de clich\u00e9s dans les deux formats, \u00e0 l\u2019aide du capteur photo du Nexus 5. Comme vous pourrez l\u2019observer, le niveau de d\u00e9tail<\/strong> est optimal, notamment sur la premi\u00e8re image de la Porsche o\u00f9 la carrosserie est loin d\u2019\u00eatre aussi propre qu\u2019elle ne le para\u00eet sur l\u2019image en JPEG.<\/p>\n
A gauche, le format DNG, \u00e0 droite, le format JPEG. Cliquez sur les images pour les agrandir.<\/p>\n
