ELECTRONIC SHUTTER CONTROL IN IMAGE SENSORS |
摘要 |
An image sensor includes an electronic shutter layer that is used to drain charge away from the photosensitive regions during an electronic shutter operation. A current reference component is electrically connected to a contact to the electronic shutter layer. The current reference component produces a signal having a level that is constant as a load current varies from zero to a threshold current level. A scaler component is electrically connected between the current reference component and an electronic shutter pulse driver component. The scaler component transmits the signal to the electronic shutter pulse driver component when the load current does not exceed the threshold current level. When the load current exceeds the threshold current level, the scaler component scales the level of the signal to a different level and transmits the scaled signal to the electronic shutter pulse driver component.
