Abstract
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 sensing component and a selector component are electrically connected to a contact to the electronic shutter layer in the image sensor. The current sensing component senses a current level in the electronic shutter layer and changes a state of an alert signal when the current level equals or exceeds a threshold current level. The selector component receives the alert signal from the current sensing component and a shutter signal from an electronic shutter pulse driver component. Depending on the state of the alert signal, the selector component either transmits, or does not transmit, the shutter signal to the electronic shutter layer. An electronic shutter operation is performed when the electronic shutter layer receives the shutter signal.
