Abstract:
1. A method of operating an image capture apparatus comprising at least one processor; at least one memory, and an image capture device having an image capture area in which images placed in said area are captured as digital image data, to capture a document image having physical area greater than said image capture area, said method comprising the steps of: receiving an input instruction signal instructing said apparatus to adopt an image capture mode, in which said apparatus captures a first image data followed by a second image data; capturing said first image data, said first image data corresponding with a first portion of said document; capturing said second image data, said second image data corresponding with a second portion of said document, wherein said first and second portions of said document comprise a whole of one side of said document; processing said first image data to adjust a scale of said first image data; processing said first image data to detect features of said first image data; processing said second image data to adjust a scale of said second image data; matching said first image data with said second image data by randomly selecting a plurality of identifiable features in said first image data and searching said second image data for a corresponding plurality of identifiable features and calculating a transform for matching the first image data with the second image data based on pairs of identifiable features in said first image data and corresponding identifiable features in said second image data; combining said first and second image data to produce a combined full image data representing said image having greater physical area than said image capture area.
