1. An imaging system, comprising:
a camera having a field of view that includes a scene;
a light source configured to illuminate the scene, the light source including a collimating lens and a light-emitting diode (LED) array located at a focal plane of the collimating lens, the LED array including LEDs that are independently controllable and configured to direct light to different portions of the scene;
a driver configured to electrically power the light source and independently control the LEDs in the LED array;
a three-dimensional (3D) sensor configured to determine distances from the imaging system to the respective portions of the scene; and
at least one processor configured to:
determine a set of power values from the determined distances, the power values increasing with increasing distance to the respective portions of the scene;
cause the driver to electrically power the light source to illuminate the scene such that the LEDs in the LED array are electrically powered based on the determined power values; and
cause the camera to capture an image of the scene while the scene is illuminated.
