2. Scanners are used for Making copies of any documents. Making copies of any images. Collecting data (ex: barcodes, scanning images)

3. Components of a Flat-bed Scanner

4. Scanning Speed A typical scan usually takes about 40-60 seconds. The importance of the time being used is for extracting resolution and image size.

5. All of this wouldn't be possible without the use of Bit Depth Resolution I.C.E.

6. Bit Depth Bits = Binary Digit Refers to how many bits are used to represent a given color of pixels in the image transferred from a scanner.

7. Bit Depth (cont'd) The original scanners were one bit scanners. They only presented documents in black and white only.

8. Resolution Are used to determine/resolve the difference between very close together image elements.

9. I.C.E. I – Image C – Correction E – Enhancement
