Abstract
A color separating filter array has a configuration in which unit elements, each having a triangular pyramid shape, are arranged two-dimensionally. Each unit elementincludes: first, second, and third filtersR,G,B arranged to form the three lateral faces of the triangular pyramid; and a reflective region. The first, second and third filtersR,G andB are designed to transmit visible radiations falling within first, second and third wavelength ranges, respectively, and reflect visible radiation falling within any other wavelength range. The reflective region is arranged to further reflect a light ray that has been incident on a region surrounded with the first, second and third filters and reflected from any of the first, second and third filters and to guide the reflected light ray to another one of the first, second and third filters that is different from the one that has already reflected the light ray once.
