Active pixel sensor array with electronic shuttering |
摘要 |
An active pixel cell includes electronic shuttering capability. The cell can be "shuttered" to prevent additional charge accumulation. One mode transfers the current charge to a storage node that is blocked against accumulation of optical radiation. The charge is sampled from a floating node. Since the charge is stored, the node can be sampled at the beginning and the end of every cycle. Another aspect allows charge to spill out of the well whenever the charge amount gets higher than some amount, thereby providing anti blooming. |
