Cheap Digital Cameras
Digital cameras have a range of features that you will almost certainly recognize if you have owned a traditional 35mm camera. These include zoom lenses and automatic flash.
As there is no film used in a digital camera the method of storing the image though is entirely different. When you take a picture light is captured by the Charge Coupled Device (CCD) and stored as a matrix of red, blue and green coloured squares. These squares are known as pixels.
The big question regarding pixels is how many your camera needs to produce prints of different sizes. The table below can be used as a guide.
