Digital camera for capturing image data with rapid response between activating a capture trigger and capturing image data

A method for capturing an image in a digital camera, the method comprising:

• using a capture buffer configured as a first memory location having a plurality of buffer locations, each of which is available for storing auxiliary image frames;
• using 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;
• continuously receiving and processing the auxiliary image frames during auxiliary mode of the digital camera and before a capture trigger is activated;
• storing the auxiliary frames in the first memory location;
• detecting activation of the capture trigger at the processing system and storing a corresponding image frame from the image sensor in another available buffer location;
• performing blur correction with the processing system on the corresponding image frame using at least one auxiliary image frame, wherein the buffer locations are designated as unavailable for image storage until the blur correction is complete;
• and
• copying one or more auxiliary image frames to the second memory location, wherein image processing is performed on the image frames and the copied corresponding auxiliary image frames in the second memory location.
