Camera with LED illumination
First Claim
1. A camera, comprising:
- a camera lens configured to capture visual data of a field of view;
a plurality of light sources configured to illuminate the field of view; and
bypass circuit coupled to the plurality of light sources and configured to bypass a subset of the plurality of light sources, wherein the bypass circuit is configured to select one of a plurality of light source subsets, and at least two of the plurality of light source subsets include distinct light source members configured to illuminate different regions of the field of view of the camera;
wherein;
the camera includes a first mode and a second mode;
in the first mode, the plurality of light sources are electrically coupled to form a string and driven by a boosted drive voltage; and
in the second mode, the one of the plurality of light source subsets is selected and driven by a regular drive voltage that is lower than the boosted drive voltage.

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.
