There is provided a signal processing device, a signal processing method, and a distance-measuring module that allow improvement in distance measurement accuracy. The signal processing device includes an estimation unit that estimates, in a pixel including a first tap that detects a charge photoelectrically converted by a photoelectric conversion unit and a second tap that detects the charge photoelectrically converted by the photoelectric conversion unit, a sensitivity difference between taps of the first tap and the second tap by using first to fourth detection signals obtained by detecting reflected light generated by emission light reflected by an object in first to fourth phases with respect to the emission light. The present technology can be applied to, for example, a distance-measuring module that performs distance measurement by the indirect ToF method, and the like.
