摘要： In accordance with the present invention, a system and method are described for producing pure gray tones on a multi-color document output device that includes a system for operating on device independent color data having at least three color components, which color data corresponds to one or more associated electronic documents. The system and method function to extract grayscale data from such a device independent color data description, which grayscale corresponds to a rendering and a single color space. Such resultant data, inclusive of a color data portion and a grayscale portion, is thus completed in device independent form.

摘要： A technique for using a one or two dimensional table lookup to provide the appropriate index and fraction for a second lookup table. The second lookup table can be a multi-dimensional lookup table. The one or two dimensional lookup table allows nonlinear conversion between input values and output values obtained from the second lookup table using standard linear interpolation techniques. The one or two dimensional lookup table can nonlinearly map input values to nodes in the second lookup table, nonlinearly map fractional values, or both.

摘要： A multi-bit halftone generating system provides for halftone intergeneration in printers which can print dots of plural gray scale levels. Input image data includes information for more gray scale levels than can be handled by those associated with a printing device. Higher order bits of the pixels of the electronic document are used to select a gray scale level from those available from the printer. Remaining bits are used to generate a halftone pattern which is superimposed upon this selected gray scale. Thus, improved dither rendering is quickly and efficiently accomplished and improved image generation results from using the gray scales available from the printing device.

摘要： This invention is directed to a system and method for setting output characteristics of an image rendering device. Image data encoded relative to a red-green-blue color space is received in a vector format D, such that each value of D corresponds to a red component value, a blue component value and a green component value. Data representing a contrast adjustment matrix C is then received, such that the values of the matrix C are constant values associated with a selected contrast adjustment for the image data. Data representing a saturation adjustment matrix S is then received, such that the values of the matrix S are constant values associated with a selected saturation adjustment for the image data. The values of the matrix S also correspond to values of a selected m by n masking matrix A. A brightness adjustment matrix B is then received. The values of the brightness adjustment matrix B are associated with brightness adjustment of the red component, with brightness adjustment of the green component, and with brightness adjustment of the blue component. An output image data D′ is then calculated, encoded in a vector format, such that D′=S×C×D+B.
