Abstract: An HDR image sensor supporting LED Flicker Mitigation to reduce Motion Blur and a method of operating same are provided. A timing controller circuit generates at least one control signal that controls an operation of the image sensor. A split-photodiode (PD) pixel includes at least two or more photodiodes that may be independently exposed to one or more bursts of light from a light source. A first photodiode of the two or more photodiodes has a first exposure period that is longer in duration than a second exposure period of a second photodiode of the two or more photodiodes. The second photodiode performs a fragmented exposure operation in which a plurality of exposure periods of the second photodiode are shorter in duration than the first exposure period of the first photodiode, and include both continuous and fragmented exposure periods to capture the one or more bursts of light.

Abstract: A unit pixel capable of achieving full initialization of a floating diffusion area, a pixel array including the unit pixel, and a photodetecting device including the pixel array. The unit pixel includes a photodetector, a transmission transistor for transmitting charges generated from the photodetector to a floating diffusion area, a reset transistor for initializing the floating diffusion area, and a boosting capacitor having a first terminal connected to the floating diffusion area and a second terminal to which a boosting voltage is applied.
