Abstract: 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. The dTOF sensing module is flexibly applicable to different detection scenarios.

Abstract: This application provides a lens module and a lens module control method to implement, among other features, automatic focusing and improve image definition. The lens module includes an imaging lens, a first control module, a first processing module, a liquid lens, and an image chip. The liquid lens is configured to refract an imaging beam that comes from the imaging lens, and the liquid lens comprises a transparent first flat lens and a transparent second flat lens that are parallel to each other. The first control module is configured to adjust a distance between the first flat lens and the second flat lens. The first processing module is configured to adjust a distance between the first flat lens and the second flat lens by using the first control module and based on a definition of the digital image, so as to adjust the definition of the image generated by the image chip.

Abstract: A TOF depth sensing module and image generation method are provided. The TOF depth sensing module includes a light source, a polarization filter, a beam shaper, a first optical element, a second optical element, a receiving unit and a control unit. The light source is configured to generate a beam. The polarization filter is configured to obtain a beam. The beam shaper is configured to obtain a first beam whose FOV meets a first preset range. The control unit is configured to obtain an emergent beam. The control unit is further configured to control the second optical element to deflect, to the receiving unit, a reflected beam obtained by reflecting the emergent beam. In the method, a spatial resolution of a finally obtained depth image of the target object can be improved.
