SYSTEMS AND METHODS FOR PRODUCING NARROWBAND IMAGES

摘要

A system may produce images including narrow-bandwidth colors. One or more sets of the narrow-bandwidth colors may be selected to be interpreted as substantially a same color by a user. The system may include a light source configured to produce the narrow-bandwidth colors, and/or narrow-passband filters may create narrow-bandwidth colors from light emitted by broad-spectrum light sources or color sources. Spatial and/or time multiplexing may be used to create separate narrow-bandwidth colors interpreted as substantially a same color by the user. For example, the light source and/or the narrow-passband filter elements may be adjustable and may alternate between emission of two or more narrow-bandwidth colors. A viewing device may include filters allowing the user to selectively filter the narrow-bandwidth colors. The user may filter the narrow-bandwidth colors to separate a stereoscopic image pair, to view a user-specific image, to view desired content obfuscated by an obfuscating image, and/or the like.

主权项

1. A direct-view display system for producing images comprising narrow bandwidth colors, the system comprising:
a plurality of narrow-band light sources including a first light source configured to selectively emit light in a first narrow band and a second narrow band; a plurality of pixels, each pixel comprising a first liquid crystal element configured to selectively control transmission intensity of light received from the first light source; a control mechanism configured to display an image by:
instructing the first light source to sequentially emit light in the first narrow band and the second narrow band, andselectively instructing the first liquid crystal element to pass a first intensity of light from the first light source, wherein the first and second narrow bands are selected to be interpreted as substantially a same color by a user.
