An "Easy-Pan" Camera?
Posted: Wed Apr 18, 2007 9:39 am
Hello All:
Pretty much all of the mechanical camera and televisor designs I've seen so far, whether disk or mirror based, involve rotating parts on a horizontal axis.
In the case of a static camera, this probably isn't of much consequence. However, gyroscopic forces being what they are, I would imagine that transient problems with speed control/synch might arise if one tried to pan the camera too abruptly.
I can think of two work-arounds. The first would be to install a hinged mirror at the lens to the camera. The idea is that, rather than pan the camera, we pan the mirror.
Another idea involves changing the mechanics to rotate about a vertical axis. Suitable mirrors and lenses would be required to translate the image appropriately. I've attached a crude drawing demonstrating the idea.
I thought I'd toss this out to the forum. Any thoughts?
