Zusammenfassung:The photodiode image sensor includes a lens array with individual lenses, each lens positioned over a specific photodiode. There is a light shield for each photodiode, which has a lengthened aperture with two incident light regions. Each lens is arranged over a lens region of the aperture to focus light from an object on one section of the photodiode and also so that object light directly illuminates a second section of the photodiode through a non-lens region of the aperture. Pref. there is a colour filter array positioned between the lens array and the light shield.
