Estimating the term…
Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D images.
Viewing filters comprising spectrally complementary filters, comprising:
3D viewing glasses, comprising:
A filter comprising three mutually exclusive passbands of visible light, a first passband configured to pass only a first color of light, a second passband configured to pass two spectrum adjacent colors of light comprising the first color of light and a second color of light, and a third passband configured to pass two spectrum adjacent colors of light comprising the second color of light and a third color of light.
A viewing system, comprising:
A viewing system, comprising:
A 3D viewing system comprising a first filter set comprising a projection filter and a viewing filter, wherein the projection filter has a different number of passbands than the viewing filter.
A filter system, comprising:
