摘要： An apparatus includes a neuromorphic vision unit, an array, and a controller. The neuromorphic vision unit includes a plurality of pixels to photoelectrically produce data based on light received from an object in a scene. The array includes a plurality of light sources. The controller controls the plurality of light sources at one of a plurality of granularities, at least in part based on the data.

摘要： A driver system controls a plurality of light emitting diodes (LEDs). The driver system includes a first driver to provide an LED current to each of the plurality of LEDs. The first driver includes a current mirror for the LED current provided to the plurality of LEDs. The driver system also includes a second driver to modulate the LED current provided to the plurality of LEDs.
