An image processing system may comprise a global shutter camera, an illumination emitter, and a processing system comprising at least one processor and memory. The processing system may be configured to control the image processing system to: control the illumination emitter to illuminate a scene; control the global shutter camera to capture a sequence of images of the scene, wherein the captured sequence of images includes images that are captured without illumination of the scene by the illumination emitter and images that are captured while the scene is illuminated by the illumination emitter; and determine presence of an object in the scene based on comparison of the images captured without illumination of the scene and images captured with illumination of the scene.
