Are the Sensor's Pixels Really Rectangular?
I realize that HDV is actually 1440 not 1920 pixels wide. So it's said that to cover the space that 1080 X 1920 square pixels would cover, HDV uses rectangular pixels.
But out of curiosity, do HDV sensors acutally use physically rectangularly shaped pixels? Or do they use slightly anamorphic lenses that squish 1920 into [edit] 1440? It's just something I've been wondering about. Thanks. Last edited by Peter Moretti; May 8th, 2008 at 11:53 AM. |

Just like HDCAM, the single most popular HD tape format in the world and the most widely accepted format for HD broadcast masters... 1440.

Chris, right.
I honestly was not trying to start another pixel shifting or 1440 vs 1920 thread. I'm really just curious if the pixels are physically rectangular or if the lens makes them effectively so, similar to how Hawk's anamorphic films lenses work. http://en.wikipedia.org/wiki/Anamorphic But it sounds like none of them use anamorphic lenses, it's done by the sensor. P.S. Thanks for catching the typo ;). |
