Claim 22:
23. A computer-readable non-transitory storage medium having stored therein a program to be executed by a computer of an image processing system, the program, when executed, causing the computer to control the image processing system to at least:
control a pulsed laser illumination source to illuminate a scene;
control a 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 pulsed laser illumination source and images that are captured while the scene is illuminated by the pulsed laser illumination source; 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,
wherein, when capturing an image while the scene is illuminated by the pulsed laser illumination source, the pulsed laser illumination source is controlled to provide illumination during an integration time of each pixel row of the global shutter camera for the image and without providing the illumination during an entire frame period of the image, and
wherein a ratio of a number of images captured with illumination of the scene to a number of images captured without illumination of the scene is less than one half and the ratio is dynamically adjusted based on characteristics of the object in the scene.
