    • HISTORY OF DIGITAL CAMERA
      • Digital camera technology is directly related to and evolved from the same technology that recorded television images .
      • In 1951, the first video tape recorder (VTR) captured live images from television cameras .
      • Both television/video cameras and digital cameras use a CCD (Charged Coupled Device) to sense light color and intensity.
      • In August, 1981, Sony released the Sony Mavica electronic still camera, the camera which was the first commercial electronic camera .
      CONTINUE….
      • The first digital cameras for the consumer-level market were the Apple Quick Take 100 camera (February 17 , 1994).
      • Then the Kodak DC40 camera (March 28, 1995), the Casio QV-11 (with LCD monitor, late 1995), and Sony's Cyber-Shot Digital Still Camera (1996).
      • The marketing worked and today digital cameras are everywhere.

        • CCD and CMOS
        • Digital Camera Resolution
        • Capturing Color

    • Digital Camera Basics
      • A digital image is just a long string of 1s and 0s that represent all the tiny colored dots -- or pixels -- that collectively make up the image.
      • It works like a conventional camera.
      • I t has a series of lenses that focus light to create an image of a scene .
    • CCD AND CMOS
      • The image sensor employed by most digital cameras is a charge coupled device (CCD). Some cameras use complementary metal oxide semiconductor (CMOS) .
      • Both CCD and CMOS image sensors convert light into electrons .
      • Once the sensor converts the light into electrons, it reads the value (accumulated charge) of each cell in the image .
    • Digital Camera Resolution
      • The amount of detail that the camera can capture is called the resolution .
      • It is measured in pixels. The more pixels a camera has, the more detail it can capture and the larger pictures can be without becoming blurry or "grainy."
      CONTINUE…..
      • Some typical resolutions include:
        • 256x256
        • 640x480
        • 1216x912
        • 1600x1200
        • 2240x1680
        • 4064x2704 -
    •  
    • Capturing Color
      • 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.

    • ADVANTAGES OF DIGITAL CAMERA
      • One main advantage of digital photography is you can see the results immediately.
      • Delete a shot immediately that you do not like .
      • Making room for more pictures on your memory card .
      • After shooting a picture, it is immediately available for viewing and can be quickly loaded into a computer for manipulation or printing.
    • DISADVANTAGE OF DIGITAL CAMERA
      • The cost of digital cameras can be very high.
      • These cameras are much more sensitive to breaking after being dropped or hit, as the casing is usually made of plastic.
      • They usually have poor focusing ability in poor or low-light situations.
      • Most basic digital cameras have a low dynamic range, meaning that less detail is seen in shadows and highlights.
