Abstract
A portable image projection device has a housing with first and second members pivotable between device folded and unfolded positions. First lens optics mounted within the first member are configured for projecting light modulated by a spatial light modulator along an optical axis through a first aperture with a first throw ratio with the device in the folded position. A second lens optics element movably mounted within the first member is configured for selective movement between positions of non-intersection and intersection with the optical axis. The second lens optics element is configured for cooperating with at least part of the first lens optics for projecting the light modulated by the spatial light modulator along the optical axis through a second aperture with a second throw ratio less than the first throw ratio with the device in the unfolded position.
