What Digital camera is
A portable camera that records images in a machine-readable format. These cameras eliminate the expensive and time-consuming methods normally involved in creating computer-readable images, including film processing and image scanning.
The meaning of Animated GIF
A type of GIF format that allows a series of static images to be displayed one after another or on top of each other, giving the effect of motion or animation. Since their implementation in Netscape Navigator 2.0, animated GIFs have been one of the easiest ways to put animation and movement on Web pages. Animated GIFs have been around since the introduction of the GIF89a format in 1989, but they didn't appear on the Web at that time because Web browsers initially did not support GIF89a's animation features.
