Abstract
The present invention relates to methods for dynamically displaying images on a display window of a digital display device such as a digital picture frame. These methods include the steps of: processing the source image into a canvas image having canvas pixels as a function of the source image characteristics; upon the canvas image meeting one or more conditions for the panning of an image, selecting a panning velocity for the canvas image; defining a viewing window with respect to the canvas image wherein said viewing window having a viewing image, said viewing image is to have a plurality of viewing pixels; calculating the viewing pixels for said viewing image; displaying said viewing image for said viewing window on said display window; redefining said viewing window with respect to the canvas image as a function of said panning velocity; and repeating the calculating and displaying steps for said viewing window. These methods allow for the dynamic display of images with special effects on a digital display device as a function of the properties of the image (e.g. a panoramic image). They also provide for the smooth panning of digital images at velocities that are accurate up to fractional pixels per unit time.
