Problems solved by technology

[0002] Multiple projectors with independent light sources (i.e., uncorrelated light sources) can be difficult to match in brightness and color
Therefore, images projected by these projectors will appear mismatched
This can be especially problematic when performing projected image stitching configurations, as mismatches in luminance and chrominance can be noticeable to observers due to the close physical proximity of the images
Additionally, it can be difficult to accommodate variations in brightness and contrast from projector to projector, negatively affecting the quality of the projected image

Embodiment Construction

[0012] figure 1 A system 100 for dynamically distributing light is shown. In particular, the system 100 includes means for distributing the light emitted by the light source 104 among a plurality of projectors 108-1, 108-2 (collectively referred to as the plurality of projectors 108, and generally referred to as the projectors 108), Although only two projectors 108 are shown, it is contemplated that more than two projectors may be provided.

[0013] The nature of light source 104 and projector 108 is not particularly limited. Thus, the light source 104 may be any suitable light source, such as a xenon arc lamp, a laser light source, or a light emitting diode (LED) light source, among others. The light source 104 may also include more than one of the aforementioned light sources, or a combination of these light sources. Also, each of projectors 108-1 and 108-2 may be any of a variety of projector types, although without their own internal light source. For example, projecto...

Abstract

A system and apparatus for dynamically distributing light are provided. The apparatus includes a source conduit configured to collect light from a light source and transmit the collected light for emission towards an optical switch. The optical switch is moveable between several discrete resting positions, each corresponding to a different one of a plurality of projector conduits. In each resting position, the optical switch directs light from the source conduit to a corresponding projector conduit. Each projector conduit receives the directed light from the optical switch and transmits the light to a corresponding one of a plurality of projectors. The optical switch is also configured to rest at each of the resting positions for respective portions of a given period of time, to regulate what amount of the light emitted by the source conduit during the period of time is received by each projector conduit.

Description

technical field [0001] The present description relates generally to image projection systems, and in particular, to systems and devices for dynamically distributing light among multiple projectors. Background technique [0002] Multiple projectors with independent light sources (ie, unrelated light sources) can be difficult to match in brightness and chromaticity. Therefore, the images projected by these projectors will appear mismatched. This can be especially problematic when performing projected image stitching configurations, as mismatches in luminance and chrominance can be noticeable to observers due to the close physical proximity of the images. Additionally, it can be difficult to accommodate variations in brightness and contrast from projector to projector, negatively affecting the quality of the projected image. Contents of the invention [0003] According to one aspect of the specification, there is provided a dynamically adjustable light distribution device c...
