Les webcams et l’USB 1.1

Par : Pierre Dandumont — 18 juin 2020 à 08:00

En repassant sur de vieux sujets du blog (je vais en reparler, ça va faire 10 ans…), je suis retombé sur un post sur les webcams et l’UVC. Et je me suis (re)posé la question de la présence de la compatibilité USB 1.1.

L’UVC, pour rappel, est la norme utilisée pour les webcams qui fonctionnent « sans pilote ». Il y en a bien un, évidemment, mais il est généralement intégré à l’OS. Sous Mac OS X, il existe depuis Tiger, avec les premiers Mac dotés d’une webcam interne (iMac G5). En pratique, un Tiger à jour supporte donc l’UVC. Pourquoi se poser la question de l’USB 1.1 ? Parce que certains Mac ne prennent en charge que cette norme, comme les PowerBook G4 Titanium.

La majorité des webcams attend une connexion USB 2.0, suffisante pour du 1080p30 (en gros) et quelques modèles récents nécessitent de l’USB 3.0, comme les derniers modèles de Logitech. Mais l’USB 1.1, ce n’est pas systématique : certains modèles ne supportent pas la norme, d’autres offrent une qualité déplorable. Pour se donner une idée, l’USB 1.1 permet en gros d’atteindre le VGA à 15 ou 20 images/s.

J’ai testé avec trois caméras chez moi, pour voir comment elles se comportent. La première est mon otoscope. En USB 2.0, on peut faire du VGA, en USB 1.1, c’est très léger : 320 x 240 à 4 fps ou 160 x 120 à 15 fps. En gros, c’est inutilisable. Avec une C270, on peut en théorie monter en 800 x 600 à 15 fps ou en 640 x 480 à 30 fps. Et avec une C930, on reste en 640 x 480 à 30 fps. Dans mon cas, je n’ai pas testé directement sur un Mac en USB 1.1, mais je suis passé par un vieux clavier Apple avec un hub USB 1.1 intégré.

La C930


La C270


L’otoscope


C’est très moche

Mes trois webcams supportent donc bien l’USB 1.1, mais le résultat varie. L’otoscope est inutilisable, les deux autres fonctionnent en VGA avec une qualité correcte. Assez bizarrement, l’image de la C930 (en temps réel) est extrêmement saccadée, mais QuickTime enregistre bien à 15 fps. La C270, un modèle d’entrée de gamme, monte à 20 fps dans le même cas, mais l’image est moins bonne en réalité. La comparaison est un peu compliquée : la C930 a un angle de vue plus large.

Je ne suis pas certain que toutes les webcams supportent bien l’USB 1.1 – les quelques pages que j’ai trouvé indiquent que ce n’est pas toujours le cas – mais vous devriez en trouver facilement. Bien évidemment, c’est toujours mieux de mettre de l’USB 2.0 dans le Mac si c’est possible, par exemple avec une carte PC Card pour les PC portables.

Téléchargez des créatures venues du fond des âges

Par : Shadows — 5 juin 2020 à 12:29

Le Museum d’Histoire Naturelle de l’Université d’Oxford organise cet été une exposition intitulée First Animals, centrée sur les premiers animaux connus et en particulier sur ce que l’on appelle l’explosion du Cambrien : il y a environ 540 millions d’années, un foisonnement extraordinaire de créatures sous-marines aux anatomies surprenantes. De nombreuses lignées apparues à cette époque n’ont pas donné de descendants vivant de nos jours.

Le Museum a eu l’excellente idée, en complément de son exposition physique, de proposer une version en ligne riche en informations. En outre, les modèles 3D présentés ont été mis à disposition sur Sketchfab, sous licence libre (Creative Commons – Attribution – Non Commercial) : vous pourrez donc les télécharger et les utiliser dans vos projets.

Voici une sélection de ces modèles. Comme vous pourrez le constater, certains sont animés. N’hésitez pas à consulter les pages Sketchfab et l’exposition en ligne évoquée plus haut pour obtenir des informations scientifiques sur ces créatures.
