A projection device comprising:
- an optical system mounted within the projection device and having an optical system axis;
- and
- a combination control operatively coupled to the optical system, the combination control including at least two different user-manipulable controls having parallel control axes that are non-parallel to the optical system axis.
A projection device comprising:
- an image-generation device including a light source and an optical system including a projector lens;
- and
- a combination control positioned apart from the projector lens and including a zoom control operatively coupled to the optical system and a focus control substantially adjacent to the zoom control and operatively coupled to the optical system, wherein the zoom control and the focus control are concentric.
A projection device comprising:
- a body;
- an optical system mounted within the body and adapted to project an image through an opening in a first side of the body;
- and
- a combination control disposed on a second side of the body, wherein the combination control includes a first adjuster and a second adjuster, where the first adjuster and the second adjuster are concentric.
