Abstract
An imaging system may include an image sensor having an array of image pixels. Each image pixel may include an electronic shutter for controlling when a photosensor in the image pixel accumulates charge. The electronic shutter may be operable in an open state during which charge is allowed to accumulate on the photosensor and a closed state during which charge is drained from the photosensor. The electronic shutter may be cycled through multiple open and closed states during an image frame capture. At the end of each open state, the charge that has been acquired on the photosensor may be transferred from the photosensor to a pixel memory element. By breaking up the total exposure time for a pixel during an image frame into shorter, non-continuous periods of exposure time, dynamic scenery image artifacts may be minimized while maintaining the desired total exposure time.
