Infrared-assisted pre-flash

Abstract:

Methods, systems, and devices for operating a camera-enabled device are described. The camera-enabled device may emit, via a first light emitting source, an infrared light in a physical environment and determine time-of-flight information associated with a target object in the physical environment based on the emitted infrared light. The camera-enabled device may estimate one or more exposure settings based on the time-of-flight information, and emit, via a second light emitting source, a visible light in the physical environment based on the estimated one or more exposure settings. As a result, the camera-enabled device may capture an image of the physical environment based on the emitted visible light and the estimated one or more exposure settings.
