Patent ID: 7289147

Claim:
A digital camera system comprising: a lens; an image sensor for sensing an image viewed by the lens; a display for displaying the image sensed by the image sensor; a volatile storage device for storing the image sensed by the image sensor; processing circuitry coupled to the display, image sensor, and nonvolatile storage device; and a processing algorithm that runs on the processing circuitry that implements an edge detection filter that: captures an image that is to be used as part of a panorama image sequence; processes the captured image using the edge detection filter; applies the edge detection filter to a portion of the captured image that will overlap with a subsequent image of the panorama sequence; computes a histogram of resultant values derived from the edge detection filter to identify a threshold value that is related to a number of edges of the processed image; alters the threshold value such that the number of displayed edges will be decreased; extracts image pixels near the edges of the captured image; and superimposes the extracted pixels over the liveview image of the subsequent image.
