1. A method of augmenting sight for a user, the method comprising the steps of: obtaining a field of view image of a scene viewed by the user using a forward-facing two-dimensional image-capture device carried by the user; transmitting the obtained image to a processor carried by the user; selecting a region of interest within either the field of view image or a second image; selecting an image modification to be applied to the region of interest by the processor; operating, by the processor, upon the region of interest to create a modified region of interest image in response to the selected image modification; digitally combining the field of view image and the modified region of interest image such that the modified region of interest image replaces image content from the location of the region of interest of the field of view image to form a hybrid image; and displaying the hybrid image on a two-dimensional display device carried by the user; wherein the field of view image is one of a plurality of field of view images captured by the forward-facing two-dimensional image-capture device and transmitted to the processor at a first frame rate; the region of interest image is one of a plurality of region of interest images transmitted to the processor at a second frame rate; and the processor generates a plurality of hybrid display images by combining the plurality of field of view images at the first frame rate and the modified plurality of region of interest images at the second frame rate.
