Abstract:
1. A digital camera for capturing an image comprising: an image sensor; a capture trigger; a capture buffer configured as a first memory location comprising a plurality of buffer locations, each of which is available for storing auxiliary image frames; a second memory location separate from the capture buffer, the second memory location configured to store image frames, wherein each image frame corresponds to an associated auxiliary image frame; a processing system configured to continuously receive and process the auxiliary image frames during auxiliary mode of the digital camera and before the capture trigger is activated, to store the auxiliary frames in the first memory location, to detect activation of the capture trigger and receive a corresponding image frame from the image sensor, to store the corresponding image frame in the second memory location, to perform blur correction on the corresponding image frame using at least one auxiliary image frame, to designate as unavailable for image storage the buffer locations in which the corresponding image frame and the at least one auxiliary image frame are stored until the blur correction is complete and to copy one or more auxiliary image frames to the second memory location for performing image processing on the image frames and the copied corresponding auxiliary image frames in the second memory location.
