Raster Graphics
Solution
- What bandwidth (measured in bytes per second) is required for feeding
the DACs for a 1024x1024, 24 bit, 60 Hz colour display?
- How might one build a raster display system that does not
use a framebuffer?
- The ability to quickly change colour-map entries is sometimes exploited
for playing animations instead of changing the contents of the framebuffer.
How could one animate a blue ball on a white background by
using this type of colour-map animation?
- Suppose a standard NTSC television monitor has a resolution
of 648x486 displayed at 30Hz, and that we wish to provide 24 bits
of colour information for each pixel. How many seconds of uncompressed
digital video of this type could fit on a 1 Gigabyte disk?
- How do LCD displays and active matrix displays work?
- In CRTs, how does one prevent the red electron gun from emitting
electrons which strike the blue or green phosphors?
