1. A method for providing improved eye safety while operating an image projection system, comprising: a. operating an image projection system that generates a modulated light beam which forms images on a display surface; b. monitoring an area in front of the display surface, and at least inclusive of the display surface, with an image capture device; c. analyzing images acquired by an image capture device to locate subjects that can obstruct a portion of the modulated light beam prior to the display surface, the image analysis including feature extraction analysis of the images of the subjects to identify candidate head regions therein, and the image analysis further including motion analysis to track motion of the subjects; d. determining a head blanking region and associated head monitoring regions for a candidate head region associated with a subject; e. blanking image projection to at least the head blanking region by substantially reducing the light levels of the modulated light beam provided to the head blanking region; f. prioritizing ongoing image analysis to the associated head monitoring regions to determine new head positions as the subject moves; and g. modifying head region image blanking to track and overlap the new head positions.
