Abstract
Light (22) is projected from an image projector (20), in response to an image information signal (18) and is controllably refracted in response to a first control signal (26), for projecting refracted light (27) onto a screen (28). The screened light is for providing viewable images of varying size occupying all or part of the screen. The viewable images are refracted in response to a second control signal (64) for viewing the images of increasingly smaller size with correspondingly increasing magnification.
Claims3
Method, comprising the steps of:
- projecting light (22) from an image projector (20), in response to an image information signal (18),
- controllably refracting said projected light, in response to a first control signal (26), for projecting refracted light (27) for providing viewable images of varying extent, and
- controllably refracting said viewable images in response to a second control signal (64) for viewing said images of increasingly smaller extent with correspondingly increasing magnification.
Device, comprising:
- a projector (20), responsive to an image information signal (18), for providing first light rays (22);
- a first optic (24), responsive to the first light rays and to a first control signal, for providing second light rays (27);
- a screen (28), responsive to the second light rays (27), for providing third light rays (29) indicative of images of varying size;
- and
- a second optic (60), responsive to the third light rays and to a second control signal, for providing fourth light rays (64) for viewing.

Device, comprising:
- an image projector (20) for projecting light (22) in response to an image information signal (8),
- a first optic (24) for controllably refracting said projected light, in response to a first control signal (26), for providing light rays (27) of varying extent, and
- a second optic (60) for controllably refracting said light rays (27) in response to a second control signal (64) for providing light rays (65) of increasingly smaller extent at correspondingly decreasing focal length.
