An imaging assembly for capturing at least one object appearing in a field of view (FOV) is provided that includes an image capturing system, a controller operatively coupled to the image capturing system to control operation thereof, and a processor operatively coupled to the controller. The image capturing system is adapted to capture an image having at least one sub-frame and is further adapted to obtain distance information of the object. The processor analyzes the image to determine a brightness value of at least a portion of the image and analyzes the distance information of the object to determine a distance value from the imaging assembly to the object. The processor further determines an illumination characteristic based on the brightness value and the distance value.
