     Did you ever wonder just how a digital camera works?  A digital camera is different from a traditional camera in that it takes digital images.  Digital images are long strings of zeros and ones that make up all the colored dots in an image.  These dots are called pixels.

     Most digital cameras create a digital image by using a sensor called a charge coupled device (CCD).  The CCD coverts light into electrons and reads it values.  "A 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."

     The quality of your picture is effected by how many pixels your camera captures.  This is called the resolution.  The higher the resolution the more pixels the camera has captured.  The higher the resolution the larger you can print or view the image without it becoming blurry.
