How to convert Color Images to Gray Images

There are some techniques to do this, and below is the one of them:

To convert color image to gray image convert all pixels like this pseudo code:

PIXEL clr;
COLOR old,new;

FOR  ALL clr in image DO
    old = clr.color; = 0.5 *  + 0.3 * + 0.2 *; = 0.5 *  + 0.3 * + 0.2 *; = 0.5 *  + 0.3 * + 0.2 *;
    clr.color = new;

For example:

A pixel with red = 94, green = 210, blue = 23
Convert to red = 115, green = 115, blue = 115

red = green = blue = 0.5*94 + 0.3*210 + 0.2*23 = 47+63+4.6 = 114.6 = 115
