Abstract
This application discloses a camera including a camera lens, a plurality of light sources and bypass circuit. The camera lens is configured to capture visual data of a field of view, and the light sources are configured to illuminate the field of view. The bypass circuit is coupled to the light sources, and configured to group the light sources into a plurality of light source subsets. At least two of the light source subsets include distinct light source members to illuminate different regions of the field of view of the camera. The camera includes a first mode in which the light sources are electrically coupled in series to form a string and driven by a boosted drive voltage, and a second mode in which one of the light source subsets is selected and driven by a regular drive voltage that is lower than the boosted drive voltage.
