1. A method implemented on a processor-based digital image acquisition device of generating one or more new digital images using an original digitally-acquired image including a selected image feature, comprising: tracking a location of a selected image feature within a stream of acquired digital images; locking focus on the selected image feature, including continuously adjusting focus based on changes of locations of said selected image feature within said stream of acquired digital images; identifying one or more groups of pixels that correspond to the selected image feature within an original digitally-acquired image based on the location tracking and focus locking; selecting a portion of the original image that includes the one or more groups of pixels; determining an orientation of the selected image feature within the one or more groups of pixels; automatically generating values of pixels of one or more new images based on the selected portion in a manner which includes the selected image feature within the one or more new images; determining one or more simulated camera movements based on the orientation of the selected image feature within the one or more groups of pixels, wherein the automatically generating values of pixels of one or more new images comprises simulating a changing direction of the selected image feature in two or more images in sequence based on the one or more simulated camera movements; and transmitting, storing, or displaying at least one of the new images or a further processed version, or combinations thereof.
