  • Accumulating charge from multiple imaging exposure periods
    Patent number: 9851245
    Abstract: Embodiments related to accumulating charge during multiple exposure periods in a time-of-flight depth camera are disclosed. For example, one embodiment provides a method including accumulating a first charge on a photodetector during a first exposure period for a first light pulse, transferring the first charge to a charge storage mechanism, accumulating a second charge during a second exposure period for the first light pulse, and transferring the second charge to the charge storage mechanism. The method further includes accumulating an additional first charge during a first exposure period for a second light pulse, adding the additional first charge to the first charge to form an updated first charge, accumulating an additional second charge on the photodetector for a second exposure period for the second light pulse, and adding the additional second charge to the second charge to form an updated second charge.
