Definition of: digital camera
A still camera that records images in digital form. Unlike traditional film cameras that record a light image on film (analog), digital cameras record discrete numbers for storage on a flash memory card or optical disc. As with all digital devices, there is a fixed, maximum resolution and number of colors that can be represented. Images are transferred to the computer with a USB cable, a memory card or wireless. Digital video cameras (see camcorder) also use FireWire.
Digital Advantages
There are three distinct advantages of digital cameras over their analog counterparts. First, you can review the finished image immediately and erase the others. Second, you can take and print one picture without waiting to develop an entire roll of film. Finally, memory cards, the storage mechanism most widely used for "digital film," are reusable over and over.
