ABSTRACT:
A method and apparatus relating to image reproduction by displays and printers capable of different dot size or different spot intensity generations. The reproduction is based upon scanned image data including gray scale values individually representing the image intensity at each picture element location (pixel). The display and printing devices generate either different size dots or spots of different intensities at each pixel location. The image processing algorithm assigns to each pixel location an appropriate printing or display dot size (or spot intensity as the case may be) to reproduce an image closely resembling the original. The resulting print dot selection represents both a good approximation of the original gray scale value at that pixel location, and an accurate gray scale reproduction of the image collectively. Additionally, this algorithm is suitable for image reproduction including line copy imagery, halftone and continuous tone pictorials.
