Keywords: The question is


How does one convert a pixel defined by an R, G, B value into
a single Gray level?

Gray = (R+G+B) / 3  ???

It seems like the R, G, B components should have different weights since
I'm aware that the eye is less sensitive to blue light.

Anyways, please E-MAIL all responses.
