1. Define Aspect Ratio
Aspect Ratio is an indicator of the proportional relationship of the width to the height of the screen and is depicted with the expression x:y, where x equals the number of units wide and y equals the number of units high.
2. List the aspect ratios for the following formats:
- 10" tablet (9.7" display): 4:3
- Smartphone (4.7" display): 667:375
- Leaderboard Ad: 364:45
- HDTV: 16:9
3. Explain the difference between Interlaced & Progressive scanning. Embed an image(s) that illustrate each.
Interlaced scanning scans each frame of an image which is captured in two parts and is transmitted separately, one field at a time. Progressive scanning scans the lines of an image from top to bottom. Interlaced is used mainly for TV while Progressive is used mainly for computers.
