The 1-CCD models must filter the input into three colors,

essentially dividing the pixel count by three for a pure

red, green, or blue color; the 3-CCD models have a complete

CCD for each of these colors, and the minimum pixel count

for full resolution (NTSC) is 340,000 pixels... Fortunately

for the 1-chippers, most colors are mixes, and not pure

R, G, or B - and the high pixel-counts of some can also

help, giving higher overall resolution (though this is

unfortunately not without some drawbacks, like lowered

sensitivity and increased motion-artifacting...).
