ABSTRACT:
Spectral separation filters for channels of a 3D image projection incorporate passbands of primary colors. In at least one of the filters, passbands are present in more than 3 primary colors. A set of 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 primary passbands of the first filter allow for an increased color space in projections through the filters compared to filters only having red, green, and blue primaries. The added flexibility of the increased color space is utilized to more closely match a color space and white point of a projector in which the filters are used.
