Abstract:
A method of displaying a zoomed version of stored image on a display, where the stored image is defined by a set of data entries mapped to respective pixels of the display, the method comprising the steps of:(1) scaling the stored image relative to the display in accordance with a desired zooming ratio; (2) displaying the scaled image at an initial position relative to the display; (3) determining the extent to which each display pixel is overlapped by features of the scaled image, and assigning to each display pixel a corresponding colour tone; (4) shifting the scaled image relative to said initial position one or more times and, for the or each shift, repeating step (3); and (5) cyclically displaying each of the sets of assigned colour tones in turn for as long as the zoomed version is to be displayed, wherein said shifting occurs with time intervals long enough to allow successive displayed sets of assigned colour tones to be perceived separately in different discrete positions by a user.
