Instead of film in conventional cameras, a digital camera has a sensor that converts light into electrical charges. \n\nThe image sensor employed by most digital cameras is a charge coupled device (CCD). Some cameras use complementary metal oxide semiconductor (CMOS) technology instead. Both CCD and CMOS image sensors convert light into electrons.\n\nOnce the sensor converts the light into electrons, it reads the value (accumulated charge) of each cell in the image.\nThis is where the differences between the two main sensor types kick in: \n\nA CCD transports the charge across the chip and reads it at one corner of the array. An analog-to-digital converter (ADC) then turns each pixel's value into a digital value by measuring the amount of charge at each photosite and converting that measurement to binary form. \n\nCMOS devices use several transistors at each pixel to amplify and move the charge using more traditional wires. The CMOS signal is digital, so it needs no ADC. \n\nUnfortunately, each photosite is colorblind. It only keeps track of the total intensity of the light that strikes its surface. In order to get a full color image, most sensors use filtering to look at the light in its three primary colors. Once the camera records all three colors, it combines them to create the full spectrum. \n\nDigital cameras use specialized demosaicing algorithms to convert this mosaic into an equally sized mosaic of true colors. The key is that each colored pixel can be used more than once. The true color of a single pixel can be determined by averaging the values from the closest surrounding pixels.

A web camera (or webcam) is a real time camera whose images can be accessed using the World Wide Web, instant messaging, PC video calling application, video conferencing, etc. Generally, a digital camera delivers images to a web server, either continuously or at regular intervals.\n\nInitially intended for personal videoconferencing, it was quickly realised that World Wide Web users enjoyed viewing images from cameras set up by others elsewhere in the world. While the term "webcam" refers to the technology generally, the first part of the term ("web-") is often replaced with a word describing what can be viewed with the camera, such as a nestcam or streetcam.\n\nToday there are thousands of webcams that provide views into homes, offices and other buildings as well as providing panoramic views of cities (Metrocams) and the countryside. Images from satellites are frequently posted on the World Wide Web. Webcams are also used to monitor traffic with TraffiCams, the weather with WeatherCams and even volcanos with VolcanoCams.\n\nA webcam is also the name of a class of video camera devices which connect directly to the PC for the purpose of video calling over the Internet.

All digital cameras should come with the software to load onto the pc. Once that is done it should be a simple case of connecting your camera to your pc via the usb cable and uploading the pics should be automatic

A camcorder can be used as webcam, not a digital camera.\n\nNow, if you digital camera has capability of capturing or rendering video, then probably you might be able to.\n\nCamcorders / Digital cameras come with USB cables. You should first intall the camcorder / digital camera software on your computer. Then shut down your PC. Turn ON your camera and then connect your camcorder / digital camera to the USB port of your computer. (The restart is necessary because the camera drivers will only be installed when the registry is logged off and on). Once the PC is restarted, it might go through camera driver installation. (that is normal). Once all is set, start up your favorite conferencing / IM software and start your webcam. You should be able to view the videos... Dont forget to turn on your camera during this process. else your computer wont recognize any new hardware. \n\nHope that helps

Okay.. It's definately a digital camera because you can upload picture. Go to the picture and look for a little trash can or X. Click that and then it should say are you sure you want to delete it. Click yes and your good. If that isn't there, look to the picture and then a little trashcan or X button on the camera itself.

Photography is the process of making pictures by means of the action of light. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices known as cameras.\nLens and mounting of a large format camera\nEnlarge\nLens and mounting of a large format camera\nWikibooks\nWikibooks has more about this subject:\nPhotography\n\nThe word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graphê, together meaning "drawing with light" or "representation by means of lines" or "drawing." Traditionally the product of photography has been called a photograph. The term photo is an abbreviation, many people also call them pictures. In digital photography, the term image has begun to replace photograph. (The term image is traditional in geometric optics.)\n\n\n\nUses of photography\n\nPhotography can be classified under imaging technology and has gained the interest of scientists and artists from its inception. Scientists have used its capacity to make accurate recordings, such as Eadweard Muybridge in his study of human and animal locomotion (1887). Artists have been equally interested by this aspect but have also tried to explore other avenues than the photo-mechanical representation of reality, such as the pictorialist movement. Military, police and security forces use photography for surveillance, recognition and data storage. Photography is used to preserve memories of favourites and as a source of entertainment.\n\n\nHistory of photography\nNicéphore Niépce's earliest surviving photograph, c. 1826\nEnlarge\nNicéphore Niépce's earliest surviving photograph, c. 1826\nSketch of the same scene\nEnlarge\nSketch of the same scene\n[edit]\n\nInvention\n\n    Main article: History of the camera\n\n[edit]\n\nChemical photography\n\nFor centuries images have been projected onto surfaces. The camera obscura and the camera lucida were used by artists to trace scenes as early as the 16th century. These early cameras did not fix an image in time; they only projected what passed through an opening in the wall of a darkened room onto a surface. In effect, the entire room was turned into a large pinhole camera. Indeed, the phrase camera obscura literally means "darkened room," and it is after these darkened rooms that all modern cameras have been named.\n\nThe first photograph is considered to be an image produced in 1826 by the French inventor Nicéphore Niépce on a polished pewter plate covered with a petroleum derivative called bitumen of Judea. It was produced with a camera, and required an eight hour exposure in bright sunshine. However this process turned out to be a dead end and Niépce began experimenting with silver compounds based on a Johann Heinrich Schultz discovery in 1724 that a silver and chalk mixture darkens when exposed to light.\n\nNiépce, in Chalon-sur-Saône, and the artist Louis Daguerre, in Paris, refined the existing silver process in a partnership. In 1833 Niépce died of a stroke, leaving his notes to Daguerre. While he had no scientific background, Daguerre made two pivotal contributions to the process. He discovered that by exposing the silver firstly to iodine vapour, before exposure to light, and then to mercury fumes after the photograph was taken, a latent image could be formed and made visible. By then bathing the plate in a salt bath the image could be fixed. In 1839 Daguerre announced that he had invented a process using silver on a copper plate called the Daguerreotype. A similar process is still used today for Polaroids. The French government bought the patent and immediately made it public domain.\n\nAcross the English Channel, William Fox Talbot had earlier discovered another means to fix a silver process image but had kept it secret.

No they don't.  But you can use software to make the camera take snapshots at certain time intervals.

ok, so youre starting out and will need a camera which actually lets you control the settings such as apperature, shutter time, flash, zoom, brightness as well as other criteria. Therefore look for this functionality in any camera you consider. Also download the manual from the manufacturer's website before EVER buying a piece of technology because  sellers info is notoriously inaccurate. This is usually easy to do but sometimes you have to register (for free) to gain access. It is worth it.\n\nSecondly, don't aim too high, yes a Sony with it's Carl Zeis lenses and matching price tag will take stunning pictures but in the hands of a sweaty amateur or most average users will prove to be no better than a comparable model of different brand. Now in answer to your question, i have recently bought a digital camera with the same intentions and my recomendations is the Acer 6MP, 3x Optical zoom (a necessity):\n\nBrand: ACER\nModel: CI-6330\n\nPRICE: £90.00 (inc VAT)\n\nStunning camera with expert results Get it from eBuyer at the following address\nhttp://www.ebuyer.com/customer/products/index.html?rb=16524488124&action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=101570

Hi, you can use "Irfan View" or "ACDSee" to view and organize your digital photography. If you are using Windows XP then you can also view thumbnails from the view menu. Other than these you can also install MS Office Picture Viewer to view your photos. My preference is Irfan View because it is free and it allows you to make photo shows etc.

two options: a scanner, or a good camera.

Depends..\n\nIf you're wanting to get new photos on the computer, then a digital camera is the choice.\n\nIf you're want to empty the photo albums and get them digitized, then you need a scanner.\n\nAnd if you want to do both and you're on a tight budget, buy a $100 Scanner and spend a couple hundred on a digital camera.  And you'll have a good mix.

Digital video is a type of video recording system that works by using a digital, rather than analog, representation of the video signal. This generic term is not to be confused with the name DV, which is a specific type of digital video. Digital video is most often recorded on tape, then distributed on optical discs, usually DVDs. There are exceptions, such as camcorders that record directly to DVDs, and Digital8 camcorders which encode digital video on conventional analog tapes.

<Photography is the process of making pictures by means of the action of light. It involves recording light patterns, as reflected from objects, onto a sensitive medium through a timed exposure. The process is done through mechanical, chemical or digital devices commonly known as cameras. \nThe word comes from the Greek words φως phos ("light"), and γραφις graphis ("stylus", "paintbrush") or γραφη graph꼯span>, together meaning "drawing with light" or "representation by means of lines", "drawing".\n\nImage forming devices\nMost commonly a camera or camera obscura is the image forming device and photographic film or a digital storage card is the recording medium, but other methods are available. For instance, the photocopy or xerography machine forms permanent images but uses the transfer of static electrical charges rather than photographic film, hence the term electrophotography. The rayographs published by Man Ray in 1922 are images produced by the shadows of objects cast on the photographic paper, without the use of a camera. And one can place objects directly on the glass of a scanner to produce pictures electronically. \nPhotographers control the camera to expose the light recording material (usually film) to light. After processing, this produces an image whose contents are acceptably sharp, bright and composed to achieve the objective of taking the photograph.\n\nIf you need more information visit the website below.
