  1. 1. DIGITAL CAMERA PREPERED BY S/LT SHEHZAD AHMED (PN) P.NO 7554
  2. 2. SCHEME OF PRESENTATION <ul><li>History of digital camera </li></ul><ul><li>Features </li></ul><ul><li>Ease of use </li></ul><ul><li>Types of cameras </li></ul><ul><li>Working principle </li></ul><ul><li>Parts of a digital camera </li></ul><ul><li>Advantages and disadvantages of digital camera </li></ul>
  3. 3. HISTORY OF DIGITAL CAMERA <ul><li>Digital camera technology is directly related to and evolved from the same technology that recorded television images . </li></ul><ul><li>In 1951, the first video tape recorder (VTR) captured live images from television cameras . </li></ul><ul><li>Both television/video cameras and digital cameras use a CCD (Charged Coupled Device) to sense light color and intensity. </li></ul><ul><li>In August, 1981, Sony released the Sony Mavica electronic still camera, the camera which was the first commercial electronic camera . </li></ul>CONTINUE….
  4. 4. <ul><li>The first digital cameras for the consumer-level market were the Apple Quick Take 100 camera (February 17 , 1994). </li></ul><ul><li>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). </li></ul><ul><li>The marketing worked and today digital cameras are everywhere. </li></ul>
  5. 5. FEATURES <ul><li>Manual Controls </li></ul><ul><li>Program Modes </li></ul><ul><li>Ease of Use </li></ul><ul><li>Size </li></ul><ul><li>Flash </li></ul><ul><li>Batteries </li></ul><ul><li>Movies and Sound </li></ul>
  6. 6. EASE OF USE <ul><li>Charging / changing batteries </li></ul><ul><li>Downloading </li></ul><ul><li>Changing settings </li></ul><ul><li>Choose size for type of use </li></ul><ul><li>Easy carrying </li></ul>
  7. 7. BRANDS OF DIGITAL CAMERA <ul><li>CANON </li></ul><ul><li>CASIO </li></ul><ul><li>FUJIFILM </li></ul><ul><li>KODAK </li></ul><ul><li>NIKON </li></ul><ul><li>OLYMPUS </li></ul><ul><li>PANASONIC </li></ul><ul><li>SAMSUNG </li></ul><ul><li>SONY </li></ul><ul><li>YASHICA </li></ul><ul><li>TOSHIBA </li></ul><ul><li>KONICA </li></ul>
  8. 8. WORKING PRINCIPLE <ul><li>The working of digital camera include following. </li></ul><ul><ul><li>Digital Camera Basics </li></ul></ul><ul><ul><li>CCD and CMOS </li></ul></ul><ul><ul><li>Digital Camera Resolution </li></ul></ul><ul><ul><li>Capturing Color </li></ul></ul>Continue…..
  9. 9. Digital Camera Basics <ul><li>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. </li></ul><ul><li>It works like a conventional camera. </li></ul><ul><li>I t has a series of lenses that focus light to create an image of a scene . </li></ul>
  10. 10. CCD AND CMOS <ul><li>The image sensor employed by most digital cameras is a charge coupled device (CCD). Some cameras use complementary metal oxide semiconductor (CMOS) . </li></ul><ul><li>Both CCD and CMOS image sensors convert light into electrons . </li></ul><ul><li>Once the sensor converts the light into electrons, it reads the value (accumulated charge) of each cell in the image . </li></ul>
  11. 11. Digital Camera Resolution <ul><li>The amount of detail that the camera can capture is called the resolution . </li></ul><ul><li>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 &quot;grainy.&quot; </li></ul>CONTINUE…..
  12. 12. <ul><li>Some typical resolutions include: </li></ul><ul><ul><li>256x256 </li></ul></ul><ul><ul><li>640x480 </li></ul></ul><ul><ul><li>1216x912 </li></ul></ul><ul><ul><li>1600x1200 </li></ul></ul><ul><ul><li>2240x1680 </li></ul></ul><ul><ul><li>4064x2704 - </li></ul></ul>
  13. 14. Capturing Color <ul><li>In order to get a full color image, most sensors use filtering to look at the light in its three primary colors . </li></ul><ul><li>Once the camera records all three colors, it combines them to create the full spectrum. </li></ul>

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