Blurred image

Can anyone tell me how I can produce a blurred or out of focus effect on a VB form?

Put a picture (with Autoredraw:ON) in a form and put the following code to a button. It works like this:
Get a square tile of a picture (e.g 3x3). Get red, green, and blue value of each pixel in the square. Combine all red values and find the mean. Do the same with green and blue.
Then apply the new value in to the pixel in the center of the square.
Ex:
| 1 | 2 | 3 | Red(0) = (Red(1) + Red(2) + Red(3) + Red(4) + Red(5) + Red(6) + _
|---|---|---| Red(7) + Red(8) + Red(9)) / 9
| 4 | 5 | 6 | Green(0) = ..... (same as above)
|---|---|---| Blue(0) = ..... (same as above)
| 7 | 8 | 9 | Apply the RGB(Red(0), Green(0), Blue(0)) in to pixel 5.

PS- I need to change the contrast in a B/W picture anybody know how ?
