  • Method and apparatus for processing and reproducing images
    Patent number: 5155598
    Abstract: Image information relating to an image is printed in a laser printer by forming image elements according to a raster pattern of image points and printing dots in a fixed number N of the image points within each image element, N being smaller than the number of image points in an image element. The image points wherein a dot is to be printed are arranged into a cluster with a minimal perimeter. The dots printed within an image element are all printed with the same intensity and thus have the same diameter, and may overlap contiguous image points in order to fill up the total area of the image element. In an embodiment the position of the cluster within each image element is selected according to the image information.
