  • 3D sensing device, lighting module and control method thereof
    Patent number: 11828587
    Abstract: A 3D sensing device configured to sense a to-be-detected object is provided. The 3D sensing device includes a lighting module and a sensing module. The lighting module includes a lighting element, an optical element group, and a drive circuit. The drive circuit is coupled to the lighting element and configured to light the first lighting region, or the second lighting region, or both the first lighting region and the second lighting region. The drive circuit can determine an optical power of the second lighting region. The lighting module selectively emits a diffused light, or a structured light, or both the diffused light and the structured light. The sensing module is adjacent to the lighting module and configured to sense the diffused light, or the structured light, or both the diffused light and the structured light reflected by the to-be-detected object.
