Abstract: A method and system are disclosed for exporting metadata from an image capture device, for example a scanner, preferably using a standard application programming interface. The metadata may be associated with a pixel, a page, or a region/object of the image, and could be used by an application, for example, to improve the quality of the image when printed or to facilitate the conversion from a single layer of image information to multi-mask mixed raster content (MRC).

Abstract: In an image input scanner, image information is acquired by sensing light from an image at an array of photosites arranged across a path of relative movement of the array and the image. To obtain resolution k, given a nominal slow scan velocity v for the relative movement between the array and the image, slow scan velocity is varied continuously over a range of 1/2 v to v. In combination, with variation of slow scan velocity over the range of 1/2 v to v, a limited scan line throw away scheme is matched to the range of velocity, where the ratio of lines kept to lines discarded in a group of lines is defined by the ratio 1:N where for every N lines, a pattern is repeated which passes 1 line of N lines, where N is a positive integer.
