OK, I guess I will quote MORE of my post, from WAY

above here...;-)

"... - 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...)."

In other words, the higher pixel count DOES affect

the motion-video (not just the stills-quality),

in BOTH good and bad ways, as I already said...;-)

And, the 1.5 megapixel TRV30/50-PC120 (and likely the

new 2-meg models) closely approach the resolution

of the VX2000, a rather remarkable thing for a 1-chipper.
