Imaging device having filters controlling light on areas of individual pixels

摘要: An imager apparatus comprises a first filter 100 operable to alternate between transmitting and reducing light from scene onto portion A of pixel 115. further, second 105 may attenuate on region B the same Filters 100, be switchable ferroelectric liquid crystal (LC) filters, controlled alternatively allow transmitted or opaque, blocking part Processor 125 controls timing 130, vertical 135 horizontal 140 drivers, increase effective resolution array, compared with system without filters; that is, filters act as shutters double each pixel. Further used - see Figures 3A 3D shared pixels Figure 4. As shown in 5, comprise polarisers.
