Black and white image at VGA

Hi

i am working on video and image processing project.

i have tvp5146 daughter-card and cyclone II device. i have 4bit 'Y' component available with me now.

(previously i had 'YCbCr' 8bits, but after setting 'Cb' and 'Cr' to zero i have 4bit 'Y' component data which i want to transmit on 'R', 'G' and 'B' to get black and white image at VGA port)

is there any body who guide me how i can do this?

Thank You

Rizwan

    To display a black and white image with RGB, you basically set all of the colors to the same value.

    So R=G=B equals the value of Y.
