Choosing the right amount of color to represent an image is critical as it impacts the memory or image buffer usage and the overall system BOM cost. For example, going back to the previous slide, a monochrome (1 bpp) in 320x240 resolution will require 9kB of frame buffer, four shades of grayscale (2 bpp) in 320x240 resolution will require 19kB of frame buffer, and etc. So, the amount of colors users need to support a graphical interface application is a tradeoff among the application usages, LCD panel size, resolution, and overall system BOM cost. While thinking about the tradeoffs, on the next slide, take a quick guess on the number of colors of each graphical interface menu.
