Abstract

For use with an imaging system, in one aspect, the present invention implements a filter system that provides a precise narrow band pass for IR-NIR wavelengths, while also providing individual dye-type filters that can be disposed above individual RGB pixels to create dedicated red, green, and blue pixel responses. An interference dichotic filter provides a non-critical first pass band that adequately encompassed RGB wavelengths, and provides a more critical IR-NIR pass band for Z-pixels. The individual dye-type filters have individual R, G, B pass band shapes that fall within the interference filter. Preferably a dye-type NIR-IR filter is also in a common optical path with the other filters to contribute to the overall filtering. In a second aspect, the invention provides an RGB-Z system with dynamically updated image renderings to better enable a viewer of the image to acquire a sense of depth.
