What does digitize mean?

Answer 1

To digitize is to rasterize. Since computers work in either on or off bits of information a picture needs to be digitzed .Which is to scan lines of informstion data in the on or off mode. (Black or white in the case of a picture) So lets say a photo is scaned at a resolution of 150 lines acroos the photo from top to bottom and depending on the image width each line has 300 on or off bits that can be big or small across the picture on the horozontal represented by these on & off bits which is dependent on grey scale brightness. It is a means of storing pictures in a stream of data that a computer can recall and reproduce on a screen or send in small packets over the internet. Simler to how a TV gets its pictutes.
