Q1

Consider three different raster systems with resolutions of 640 by 400, 1280 by 1024, and 2560 by 2048. What size frame buffer (in bytes) is needed for each of these systems to store 12 Bits per pixel and for 24 Bits?

Q2

How many bits per pixel are needed to display 256 colors in a display system?

Q3

If an image has a width of 2 inches and an height of 3 inches, what is the aspect ratio of the image?

Q4

Suppose an RGB raster system is to be designed using an 8-inch by 10-inch screen with a resolution of 100 pixels per inch in each direction. If we want to store 6 bits per pixel in the frame buffer, how much storage (in bytes) do we need for the frame buffer?

Q5

Consider two raster systems with resolutions of 640 by 480 and 1280 by 1024. How many pixels could be accessed per second in each of these systems by a display controller that refreshes the screen at a rate of 60 frames per second? What is the access time per pixel in each system?

Q6

How much time is spent scanning across each row of pixels during, screen refresh on a raster system with a resolution of 1280 by 1024 refresh rate of 60 frames per second?

Q7

How many bits per pixel are needed to display 256 colors in a display system?

Q8

If an image has a width of 2 inches and an height of 3 inches, what is the aspect ratio of the image?
