Abstract
A method of reconstructing an image captured as a stream of image data, for example as input received from a linear sensor in unconstrained scanning, comprises reconstructing the image in the form of a plurality of tiles. Each tile comprises a pixel grid of predetermined dimension representing a specific spatial region of the image. The tiles tessellate a rectilinear image space. Tiles can be created when required and compressed when no longer active, thus minimizing memory requirements. Devices utilizing this method are provided. The method is especially appropriate for use in an unconstrained hand scanner, but can also be applied to panoramic capture with a digital camera.
