DTOF SENSING MODULE, TERMINAL DEVICE, AND DISTANCE MEASUREMENT METHOD

Provided are a direct time of flight dTOF sensing module, a terminal device, and a ranging method, to resolve a problem that in a conventional technology, a dTOF sensing module cannot adapt to different detection scenarios to some extent. Every K light sensitive units (401) of W light sensitive units (401) included in the dTOF sensing module share a first storage space. A processing control unit (403) is configured to control gating of N light sensitive units (401). The gated N light sensitive units (401) occupy the first storage space, and Q time slice bins are allocated to each gated light sensitive unit (401), so that the dTOF sensing module operates in a first mode or a second mode. A quantity of gated light sensitive units (401) corresponding to the first mode is greater than a quantity of gated light sensitive units (401) corresponding to the second mode, and/or a quantity of time slice bins allocated to each light sensitive unit (401) corresponding to the first mode is less than a quantity of time slice bins allocated to each light sensitive unit (401) corresponding to the second mode, so that the dTOF sensing module is flexibly applicable to different detection scenarios.
