CMOS IMAGING DEVICE COMPRISING A MICROLENS ARRAY EXHIBITING A HIGH FILLING RATE

摘要

The invention relates to a CMOS imaging device comprising an array of photosites and a microlens array which comprises first type microlenses (L1) and second type microlenses (L2), wherein said first type microlenses (L1) are embodied according to a first circular template (G1) provided with a first radius (R1), the second type microlenses (L2) are embodied according to a second circular template (G2) provided with a second radius (R2), which is smaller that the first radius (R1), and the first (G1) and second (G2) templates are provided with overlapping areas. Said invention makes it possible to produce an imaging device provided with a high filling rate.
