Claims36
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 and having a control axis that is non-parallel to the optical system axis.
7 The projection device of claim 1, wherein the combination control is adapted to rotate around the control 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.
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.
