Abstract
A depth sensing apparatus is provided. The depth sensing apparatus may reset, to a reference voltage value, a voltage of each of a first floating diffusion node and a second floating diffusion node of a sensor pixel for a first time period. For a second time period, the depth sensing apparatus may control the first floating diffusion node to store a voltage of a photodiode in a first phase interval, and may control the second floating diffusion node to store the voltage of the photodiode in a second phase interval. The depth sensing apparatus may calculate a difference between the voltage of the first floating diffusion node and the voltage of the second floating diffusion node for a third time period.
