Document Summary

We rely on images for information, explanations, and entertainment. Non digital medium - paper copy of a photo o. Scanner saves the image on a file on computer. Digital images uploaded to a file on your computer. It only understand/speak binary (digits 0 and 1) Process of translating a piece of into binary bits (binary digit) Bit is the fundamental unit of information in a computer system. Computers built from electronic devices that have only two states: on (high) and off (low) Measurement for each bit is based on binary system (base 2) 2 to the power of bit #= number of combination o. Rule: more bits, more colours available to assign to a pixel. Consider digitizing an image, sound, video, animation, text etc and store on computer: sampling: how often do i take a sample (measurement) to represent the thing When images taken form scanner, digital camera, graphics application.
