Well said.

December 14, 2005 at 12:54 pmMy guess is that Panny has got into a deadlock with this ccd specs situation.
I believe that individual ccd’s in hvx have fewer pixels both horz & vert than 1920×1080 and this is technically the best way to achieve as good as possible PQ with this camera.Nevertheless chips (or the whole block, but nobody cares) were advertised as “1080p” and now it’s just too hard to explain to everybody that this camera produces better 1080p picture with fewer pixels in individual ccd chip.
So they will never announce the specs of the chips.And why fewer pixels are better?
Because camera is recording YCbCr (=component) picture that does not benefit from the full RGB resolution.Heck, I would even prefer 4:2:0 over 4:2:2 to get lighter compression rate.
(4:2:2 was important thing with interlaced video, not with digital progressive picture; why would we need more chroma information in one dimension than with the other with progressive picture?)So, it’s better to have larger pixels (smaller resolution) and use pixel shifting.
That way we get more sensitivity, which means wider usage for the camera and lesser noise to picture.
