A scanning and perception system for a vehicle camera having an instantaneous field of view (iFOV) and configured to capture an image of an object at a saturation level in the camera's iFOV. The system also includes a light source configured to illuminate the camera's iFOV. The system additionally includes a radar configured to determine the object's velocity and the object's distance from the vehicle, and a mechanism configured to steer the radar and/or the camera. The system also includes an electronic controller programmed to regulate the mechanism and adjust illumination intensity of the light source in response to the saturation level in the image or the determined distance to the object. The controller is also programmed to merge data indicative of the captured image and data indicative of the determined position of the object and classify the object and identify the object's position in response to the merged data.

A device receives position information from a sensor of the device, wherein the position information indicates a position of a user of the device and a position of a person proximate to the user. The device receives lighting information from the sensor, wherein the lighting information indicates lighting conditions around the device and the user. The device calculates a position adjustment for an infrared element of the device based on the position information and the lighting information, and calculates an intensity adjustment for the infrared element based on the position information and the lighting information. The device receives, via an input element of the device, input data provided by the user, and implements the position adjustment and the intensity adjustment to enable the infrared element, when illuminated, to reflect light away from the input element and to prevent image or video capture of the input data.

The system provides movement guidance to an actor using a motion capture movement reference system. The motion capture movement reference system includes a light strip having an elongated substrate with lights positioned in series along a length of the elongated substrate and a computing device configured to program the lights with an illumination protocol. Operationally, a user inputs into the computing device one or more variables to establish a number of lights to simultaneously activate and/or a rate of activating and deactivating the lights along the length of the elongated substrate. The light strip is programmed based upon the one or more variables. When the lights are activated and deactivated along the length of the elongated substrate, an actor chases the lights.
