Abstract: Image sensors and methods of operating the image sensors are provided. The image sensors may include a pixel configured to generate an image signal in response to light incident on the pixel. The pixel may include a charge collection circuit configured to collect charges, which are produced by the light incident on the pixel, during a sensing period and a floating diffusion region. The image sensor may further include a storage unit configured to store the charges and, during a transfer period after the sensing period, configured to transfer at least a portion of the charges to the floating diffusion region. An amount of charges that is transferred from the storage unit to the floating diffusion region may be controlled by a voltage level of a storage control signal that is applied to a storage control terminal of the storage unit.

Abstract: A depth pixel of a time-of-flight (ToF) sensor includes a common photogate disposed in a center region of the depth pixel, a plurality of floating diffusion regions disposed in a peripheral region surrounding the center region, a plurality of demodulation transfer gates disposed in the peripheral region, and a plurality of overflow gates disposed in the peripheral region. The demodulation transfer gates transfer a photo charge collected by the common photogate to the plurality of floating diffusion regions. The demodulation transfer gates are symmetric with respect to each of a horizontal line and a vertical line that pass through a center of the depth pixel and are substantially perpendicular to each other. The overflow gates drain the photo charge collected by the common photogate, and are symmetric with respect to each of the horizontal line and the vertical line.
