Abstract:
1. A method for operating a global shutter image sensor, the image sensor including an array of pixels and a readout circuit, wherein each of the pixels includes a photodiode and a charge coupled gate (CCG) device, wherein the readout circuit includes a floating diffusion, and wherein the method comprises: controlling the plurality of pixels such that said photodiode of each of the plurality of pixels simultaneously captures a corresponding charge in accordance with first global control signals simultaneously transmitted to every pixel in said image sensor; controlling the plurality of pixels such that said corresponding captured charges are simultaneously transferred from the photodiode to the CCG device in each of said plurality of pixels in accordance with second global control signals simultaneously transmitted to every pixel in said image sensor; and performing a rolling shutter readout operation following the transfer phase, wherein the CCG devices of the plurality of pixels are connected in series to the readout circuit, and wherein the rolling shutter readout operation includes:
