A photographic image requires 3 bytes per pixel to produce 16 million shades of color.

a) How large video memory is required to store a 640 x 480 image during display? A 1024 x 768 image? A 1280 x 1024 image?

b) How many 1024 x 768 color images will fit on a CD-ROM?

#### Solution Preview

a. a 640 x 480 image has this number of pixels:
# of pixels = 640 x 480 = 307200 pixels

Since there are 3 bytes per pixel, the amount of memory needed is:
memory size = 307200 pixels (3 bytes/pixel)
memory size = 921600 bytes

Converting into kilobytes, we have:
memory size = 921600 bytes (1 kB/ 1024bytes)
memory ...
