Abstract:
This application discloses an electronic device (e.g., a camera) that operates at two distinct modes and includes a camera lens configured to capture visual data of a field of view, a plurality of light sources, and a light source driver. The light sources are configurable to a plurality of light source subsets to illuminate the field of view. At least two of the light source subsets include distinct light source members and are configured to illuminate different regions of the field of view. The light source driver is configured to drive the light sources with two distinct drive voltages at two distinct modes. In a first mode, the light sources are electrically coupled to each other and driven by a first drive voltage. In the second mode, one of the light source subsets is selected and driven by a second drive voltage that is lower than the first dive voltage.
