  • Patent number: 5585863
    Abstract: A method for organizing and addressing memory of a digital video image is provided for one and two dimensional image processing using fast page mode accessing of memory, and also for displaying composite digital video images. A DRAM (12) is mapped to address locations storing segmented memory, non-segmented memory, line pointer tables, and horizontal description tables. The lines of a digital image are organized in DRAM (12) in either segmented memory or non-segmented memory. For segmented memory, each line of the image is broken up into equal line segments of pixels. Vertically aligned columns of line segments in the image are then stored in one or more rows of the DRAM (12). For non-segmented memory, each line is stored in a format where rows of DRAM (12) each represent a line of image data.

  • Patent number: 5140648
    Abstract: The apparatus and method of the present invention utilizes three scaling functions for bi-tonal digitized image data such as documents. The digitized document resolution (i.e. from a digitizing scanner) may be different from the resolution of an image output device (i.e. laser printer, CRT display, fax machine, etc.). The invention takes in the scanned image data and scales the data to compensate for the resolution mismatch of the output device. Although the invention is intended for document archive applications (such as scanning documents on microfilm), the scaling can be performed on any bi-tonal image.
