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 Tiles can be created when required and compressed when no longer active, thus minimizing memory requirements.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.

Abstract: An image forming apparatus includes a plurality of image forming stations each having an image carrier and forming an image on the image carrier; a mark detecting unit for detecting a plurality of registration correction marks formed on a recording medium by the plurality of image forming stations; a correction mechanism for correcting a position difference between images formed by the plurality of image forming stations in accordance with a detection result by the mark detecting unit; and a controller for independently controlling an image forming operation of each of the plurality of the image forming stations so that the image density of each of the registration correction marks formed by the plurality of image forming units has a different predetermined image density.
