ABSTRACT:
A dichroic filter that for use with an electronic imaging device, such as a camera. The dichroic filter is located in the main imaging lens, and may permit all light to pass through a first portion and be measured by a photosensor, while restricting at least some portions of visible light from passing through a second portion thereof. In this manner, only the non-restricted portions of visible light passing through the second portion may be measured by the associated pixels of the photosensor. The filter may be formed from a first aperture permitting a first set of wavelengths to pass therethrough and a second aperture adjacent the first aperture, the second aperture permitting only a subset of the first set of wavelengths to pass therethrough. The second aperture may be a dichroic mirror or it may be an optical filter of some other type.
