Abstract:
An image sensor pixel may include a photodiode that generates first charge for a first frame and second charge for a second frame, first and second storage gates coupled to the photodiode, a floating diffusion coupled to the first storage gate through a first transistor, a second transistor coupled to the second storage gate, and a capacitor coupled to the floating diffusion through a third transistor. The image sensor pixel may output image signals associated with the first charge generated by the photodiode for the first image frame while the photodiode concurrently generates the second charge for the second image frame. The second storage gate may be used to store overflow charge. Overflow charge for the second frame may be stored at the second storage gate while image signals associated with the first image frame are read out from capacitor and the floating diffusion.

Claim (Index 20):
A method of operating an image sensor pixel having a photodiode, a floating diffusion region, a capacitor, a first storage gate coupled to the photodiode, a second storage gate coupled to the photodiode, a first transistor coupled between the first storage gate and a floating diffusion region, a second transistor coupled to the second storage gate, and a third transistor coupled between the capacitor and the floating diffusion region, the method comprising:\n with the photodiode, integrating a first charge for a given image frame; with the second storage gate, storing an overflow portion of the first charge for the given image frame; with the second and third transistors, transferring the overflow portion of the first charge to the capacitor and the floating diffusion region; with the first storage gate, storing a remaining portion of the first charge after the overflow portion of the first charge has been transferred to the capacitor and the floating diffusion region; with the photodiode, integrating a second charge for a subsequent image frame while an image signal associated with the transferred overflow portion of the first charge is concurrently read out from the image sensor pixel; and with the second storage gate, storing an overflow portion of the second charge for the subsequent image frame while the image signal associated with the transferred overflow portion of the first charge is concurrently read out from the image sensor pixel.
