An image sensor with an organic photoelectric film for converting light into charge may be provided. The image sensor may include an array of image sensor pixels. Each image sensor pixel may include a charge-integrating pinned diode that collects photo-generated charge from the photoelectric film during an integration period. An anode electrode may be coupled to an n+ doped charge injection region in the charge-integrating pinned diode and may be used to convey the photo-generated charge from the photoelectric film to the charge-integrating pinned diode. Upon completion of a charge integration cycle, a first transfer transistor gate may be pulsed to move the charge from the charge-integrating pinned diode to a charge-storage pinned diode. The charge may be transferred from the charge-storage pinned diode to a floating diffusion node for readout by pulsing a gate of a second charge transfer transistor.
