Abstract:
1. A digital image acquisition apparatus, comprising: an image acquisition sensor coupled to imaging optics for acquiring a sequence of images; an image store for storing one or more of said sequence of images acquired by said sensor; a dedicated motion detector hardware unit for providing hardware-based sensor control including causing said sensor to cease capture of an image when the degree of movement of the apparatus in acquiring said image exceeds a threshold, and for selectively transferring said one or more of said images acquired by said sensor to said image store; a temporary image cache for receiving image data directly from said image acquisition sensor; and a dedicated motion extractor hardware unit configured for directly accessing said image data received at said temporary image cache and for providing hardware-based determination of motion parameters of at least one selected image stored in said temporary cache based on analyzing said image data received at said temporary image cache, wherein the dedicated motion extractor hardware unit is configured to
