Construction de l’éclairage numérique intelligent lumières Studio
Time flies, comme l'électricité, seulement quelques années, sauts de technologie TV. Comme la numérisation, informations les vagues sont une technologie audio ascendant se déplace de la télévision analogique traditionnelle à une approche numérique pour accélérer bissextile ; technologies vidéos ont été d'un âge analogique à entrer dans l'ère du numérique, plus à partir de technologies SD transmettre aux
Qualité d'image TV sans vidéo et des technologies d'éclairage, l'éclairage TV est bonne ou mauvaise, direct impact sur le ton, niveaux, clarté d'image couleur et des effets artistiques, pièce d'éclairage TV une position vitale et importante dans la production de programmes TV. Comme la technologie vidéo a inauguré une ère numérique, particulièrement nombreux télévision numérique HD Studio de construit, le fait de Panasonic CGR-DU06 Battery Charger la technologie de l'éclairage a nouveau de plus hautes exigences, le Studio éclairage du processus numérique prend également grand rôle mène, technologie d'éclairage de TV doit pour cela pour bien préparé, indépendamment de l'utilisation du dispositif d'éclairage Shang est également dans la conception de l'éclairage du concept Shang sont pour attraper l'ère de la tendance, de rencontrer Studio TV, faisant de l'ère numérique vient.
La programmation de TV est un bâtiment sur la base technique de la création artistique, idée parfaite doit utiliser certain audio et technologie vidéo et la technologie de l'éclairage peuvent être atteint. Exigences de la technologie vidéo HD numériques pour la lumière ce qui est si particulière à ce sujet ? Numérisation de l'éclairage de la TV est quel genre d'idées ? Nous devons tout d'abord des caractéristiques des appareils photo numériques pour trouver la racine du problème.
Rapport d'aspect TV traditionnelle, c'est 4:3, rapport d'aspect HD pour les 16:9, conserve la largeur de l'écran, l'image plus informatif, que l'image contient plus. Dans le contenu traditionnel est pas sur la toile, ont mis en évidence dans la HD, surtout latérales, côté de la banderole de plancher de Studio et les paysages du côté de la lumière. Comme la taille augmente, changement du point de vue de la photographie, l'emplacement de l'installation et JVC BN-VM200U Battery Charger l'angle de projection est différente dans le passé pourrait être contre possède maintenant à examiner attentivement et sélectionnez. En raison de la gamme accrue de l'éclairage, l'éclairage lumineux de renforcement précis de la région, ce qui nécessite plus de quantités de lumières et lampe automatique utilisant avec intelligence informatique pour résoudre le problème.
Balayage ligne numérique HD est 1080 lignes, clarté d'image améliorée, peuvent montrer augmentent les niveaux de l'image. Pas reflétée dans l'écran traditionnel hors ou ne savent pas d'un objet ou de la lumière, est clairement sur l'image HD doit montrer. Bien entendu, cela peut se faire par la luminosité de base accrue, la régularité et la douceur de la lumière à la fin du, ajuster le ratio de la lumière afin de refléter correctement les aspects d'objets et les relations entre les objets. D'une part, afin d'augmenter la luminosité de la répartition de la lumière, la granularité et l'augmentation le nombre de lampes utilisées ; de l'autre main plusieurs feux utilisation générera plus déraisonnable à la lumière et l'ombre, il est contradictoire à la lumière augmente beaucoup de difficulté. Émergence d'une nouvelle lampes automatique intelligent, une très bonne solution.
La sensibilité sur la caméra vidéo numérique HD améliorée, la tolérance que les caméras traditionnelles ont augmentation plus importante, ce qui signifie que le contraste d'image TV augmentant, proportion d'éclairage illumination peut être plus grande, l'éclairage de style pour plus de puissance. Numérique haute définition dans le Studio nécessitent plus délicate, voire, douce lumière, tandis que structuré de la bonne lumière que  Panasonic Lumix DMC-ZR3 Battery Charger par le biais et la concision, qui donne un éclairage Arts éclairage fournit plus de place à la créativité, mais augmente également la difficulté d'application de l'éclairage. Ce sera une lumière Division est l'un des enjeux et des nouvelles zones de développement.
Studio numérique est la tendance de la production TV, éclairage de studio numérique est le seul moyen. Il semblerait que le numérique de lumières Studio tout d'abord il nous faut changer notre façon de penser, ne peut être satisfaite pour maintenant regarde et existant de la technologie, avec de nouvelles idées d'orientation, de regarder vers l'avenir des idéologies, de découverte et de l'innovation plus sélectionnée en technologie de l'éclairage et du matériel, afin qu'elle peut s'adapter à l'évolution future de la technologie de la télévision, pour améliorer la qualité des services de télévision.
Digital éclairage elle-même ne fait pas référence aux arts d'éclairage numériques, digital fait référence au studio Studio lumières ordinateur numérique système intelligent dispositifs d'éclairage. Il fournira plus commode et meilleure pour l'éclairage des moyens et méthodes atteindre les objectifs artistiques. Système d'éclairage de studio est principalement composée de systèmes d'éclairage et de système d'éclairage, système, y compris la pendaison de pièces, de l'éclairage, l'éclairage segments de distribution de puissance ; article de gradation comprend console gradation informatisé et le cabinet de contrôle de puissance thyristor. Dans la perspective du développement de l'histoire de la technologie de l'éclairage, la mise en œuvre rapide de la gradation numérique contrôle système, même pour le développement de réseau numérique, à l'éclairage et son énorme impact sur le développement de carrière était évident.
En regardant le Studio de la station de télévision locale, petit et grand, système de distribution de la lumière est toujours en technologie relativement vers l'arrière. Technologie de système d'éclairage traditionnel en Chine n'a pas donné suffisamment l'attention et le développement, système de contrôle de l'éclairage général est toujours dans la technologie simple de contrôle numérique et les bretelles et l'Agence d'exécution  Nikon D50 Battery Charger pour les lampes à l'aide de moteur à courant continu, contrôle agit de renseignements de la simulation, ses défauts sont évidents :
Perspective on the high end DV cameras and new technology
"DV" can be said that this year's digital image culture of a keyword, not only users of a large number of parents start baby growing up as a record of important digital camera tools; enthusiasts began through the digital video camera for some image creation, created a brand new video culture. Although from the viewpoint of Nikon Coolpix S8100 Battery Charger market structure, popular digital cameras take a huge market share, but the recent development of high end products more compelling, they symbolize the future of digital photography technology.
Put in a lot of new products to the popular market in the past different this year, Sony, Panasonic, Canon and other manufacturers are focusing more on the high end. Although the basic 3CCD areas only Panasonic introduced a new product, but high pixels on a single chip CCD digital video camera in the imaging quality of made a significant breakthrough, but also represent a new technology trend. High-pixel CCD, maintenance of large diameter lens, optical image stabilizer, HD 16:9 mode sth These still appear only at the high end products characteristic believed also to the public shortly afterwards.
Irresistible trend of the high pixel
As the CCD structures on different digital cameras generally use rectangular pixels, interlaced CCD difficult to achieve comparable to the real digital camera CCD for still image, but users want a device while enabling static, dynamic shooting capacity demand is growing. Therefore, we see the development of today's digital camera CCD pixels digital camera history seemed to repeat itself a few years ago, from 800,000 pixels, 1 million, 2 million pixels to the current 3 million pixels, almost had to catch up with digital cameras.
Details in addition to providing richer still image, increase CCD pixels video shooting is also useful. First of all, currently of high end digital camera video image data gets volume has reached 1 million to 2 million pixels, although ultimately need to record DV format 400,000 pixels, but gets the amount of information, the ultimate image quality is improving. Especially in the color levels of image performance, high-end product has to a large extent out of the previous single-chip CCD digital camcorders lack details and problems of the transition. Of course, the scales video image acquisition and real-time processing of the digital camera is the core of a very big challenge, so similar, such as the Canon DIGIC DV processing engine also came into being. Secondly, the higher pixel count, larger CCD area leaves a great deal of the surrounding space for video imaging, shooting video, often almost one-third of the sensitive area around the CCD is "idle". Not only can they enable efficient electronic image anti-shake, and laid the Foundation for high definition widescreen mode is described below.
Lens "quality not quantity"
Comparison on high-end digital cameras, lenses tend to be quite prominent parts. Is not only the manufacturers in the design model as Visual lens at the core, high end lens is often itself also has a lot of volume.
If we only look at the lens specifications, may be found in popular products that can be seen in 20 times optical zoom does not appear in the high-end products, to a certain extent, zoom ratio is not the main design demands of these products. Aperture index to see these products, you will learn about their professional, they are often constant maximum aperture of F1.6 and popular product basic F1.8. Don't underestimate this aperture one-second gap in darker environments, it is often clear and fuzzy boundaries. At the same time, high-end digital cameras use CCD sizes larger, which also brings a large matching lens.
In addition, high end lenses also drew many designs from the traditional camera lenses. For example we can Sony Zeiss t * lenses found on high-end products, is to use a special coating, and as such, Canon products with the document using the Super Spectra coating, can effectively reduce glare and ghosting, creating sharp clear images. These programs constitute basic have adopted a number of blade aperture, under various aperture values, its shape is nearly perfect round, can form a natural perfect background blur effect. They are also often built-in ash density filters in, shooting in bright light environments can also use a large aperture blur the background, bringing maximum flexibility for exposure control.
Real anti-shake feature
Another point as a high-end digital camera logo is moving it's optical stabilizer, which is a set of special parts installed in the lens. First, the camera monitoring body at any time in the horizontal and vertical Gyro Sensor shake, camera jitter control circuit signals into specific displacement and driven variable angle lens in the lens movement, light refraction to the origin of the offset.
And low prices compared to the widespread use of the electronic image stabilizer, optical stabilizer does not rely on perimeter pixels of the CCD, it has a large range of  Nikon EN-EL5 Battery Charger anti-shake. Jitter detection and compensation response is very quick and effective compensation can be made to the different frequency jitter. At the same time, it can also maximize the CCD sensor imaging capability, brings outstanding high definition images.
Of course, and electronic anti-shake rely primarily on existing hardware add-on software implement different, optical anti-shake increases the optical parts, costs are markedly improved. Therefore, this also ensures that the indissoluble bond of optical anti-shake and high end digital cameras.
Widescreen high definition
As more people access to large, widescreen model has the hearts of 16:9, foreign television stations have started a 16:9 model of television. Many photographers also use it as an important film of DV footage, so 16:9 has gradually become important features of digital cameras.
Traditional digital video camera to create the widescreen effect, usually cut off top and bottom of the image, plays stretch the central part of the image. Not only does this reduce the image resolution, also reduces the perspective of the filming at the wide-angle end, were greatly reduced by widescreen Telepresence. Basic on the high-end digital cameras today have adopted a new 16:9 mode, Canon MVX10i, for example, its high resolution 16:9 pixels of the pattern using CCD peripheral extends the wide perspective of the filming, equal to 4:3 mode on both sides do not see in the image into the picture, not only improves the image quality, more effective expanded wide angle-side perspective.
In addition, high-end digital camera from a professional reference in a number of features, such as zebra stripes indicate overexposed, color bar generator, audio level manual adjustment, and so on, make it compact fuselage or on some occasions acting as a professional record of roles.
