Digital Camera
A digital camera (or digicam for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.Many compact digital still cameras can record sound and moving video as well as still photographs. In the Western market, digital cameras outsell their 35 mm film counterparts.
Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space.Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialised digital cameras. Many digital cameras include a video output port. Usually sVideo, it sends a standard-definition video signal to a television, allowing the user to show one picture at a time. Buttons or menus on the camera allow the user to select the photo, advance from one to another, or automatically send a "slide show" to the TV.HDMI has been adopted by many high-end digital camera makers, to show photos in their high-resolution quality on an HDTV.In January 2008, Silicon Image announced a new technology for sending video from mobile devices to a television in digital form. MHL sends pictures as a video stream, up to 1080p resolution, and is compatible with HDMI.Some DVD recorders and television sets can read memory cards used in cameras; alternatively several types of flash card readers have TV output capability. Most digital cameras utilize some form of removable storage to store image data. While the vast majority of the media types are some form of memory card using flash memory (CompactFlash, SD, etc.) there are storage methods that use other technologies such as Microdrives (very small hard disk drives), CD single (185 MB), and 3.5" floppy disks.

Digital Camera is one of the beautiful outcome of todays technology.It is the advance form of the camera that are being generally used. Todays world need the faster work done in every field, due to ehich these type of camera is suppoded to be boon for us.
