Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an imager in which a non-telecentric lens can be used without reducing the light collection efficiency of the pixel site.SOLUTION: An imager includes a two-dimensional array of photosensors 35, each photosensor having a center point. A non-telecentric lens is positioned over the two-dimensional array of photosensors, and a two-dimensional array of microlenses 60 is positioned over the two-dimensional array of photosensors. Each microlens is associated with a corresponding photosensor, and each microlens has a center point. A color filter array 420, 430 and 440 is positioned over the two-dimensional array of photosensors. The color filter array includes a plurality of color filter areas. Each color filter area 420 is associated with a corresponding photosensor 35 and has a center point. A layer of transmissive apertures 950 is further positioned over the two-dimensional array of photosensors.
