摘要： The embodiments describe calculating and store scaling information based on processing input binary image data. By manipulating data that is received in binary format, the most cost effective method for scaling may be chosen. The input image data is scanned, a resolution (e.g., for display or output) is determined and a scaling method is determined. If the input binary image data needs to be scaled down to a smaller resolution, the binary image data is processed and scaled and then converted to grayscale image data. If the image data must be scaled to a larger resolution, the input binary image data is first converted to grayscale image data before processing using a segmentation tag-based scaling method. The scaled image data may then be output to an output device, such as a display, printer, or image output terminal.

摘要： In a system for processing full-color image data, such as within a digital color printer or copier, a four-channel architecture is used. Three of the channels handle image data relating to primary color planes, such as CMY. In the other channel, values relating to the K value which goes with the CMY values for each pixel alternate with a B value, suitable for pure monochrome rendering of the pixel in the image. When it is desired to print or display the image in monochrome, the B values are isolated from the K values.

摘要： The methods and apparatus of this invention model and reconstruct binarized images. A grayscale image is modeled using a template matching approach. Each binarized grayscale image value is characterized by a unique set of templates which are rotations of each other. The set of templates allows construction of a look-up table between patterns and grayscale values. The look-up table is provided with a limited number of entries. As a result, the number of entries in the look-up table is reduced. The look-up table thus obtained is used for reconstructing the original grayscale image from the binarized image. The generated image quality is good in comparison with conventional methods. The process may be applied to various halftoning processes including error-diffusion processes.
