Image saving and processing

I need to save a bitmap(800 by 600) in 16bit format in less than 10-20ms. Probably, this can be done with DIB. Please, test your answers first. Also, if you know how to access the bitmap's data very fast(.Pixels and .ScanLine didn't seem to be fast enough) please send your answer. Thank you. The points can be increased for a really good solution.

why to use pf16bit? colors gets very ugly..
by using this code I get 2.84MB bitmap of my screen (1152x864@32bit) capture.
procedure TForm1.Image1DblClick(Sender: TObject);
begin
Image1.Picture.Bitmap.LoadFromClipboardFormat(cf_BitMap,
ClipBoard.GetAsHandle(cf_Bitmap), 0);
Image1.Picture.Bitmap.PixelFormat := pf24bit;
end;

procedure TForm1.Save1Click(Sender: TObject);
begin
Image1.Picture.Bitmap.SaveToFile('c:\bmp.bmp');
end;

sorr, didn't understand your q right :)
try to use pf8bit - on my P4 it's only format in which that image saves less than in 20ms (only save, not converting from pfDefice)..
