    摘要: Halftoning apparatus and method that may generate and employ average values and shifts are described herein. The apparatus may include an unpacker to determine shifts and average values for a plurality of input pixel values, each pair of average value and shift being associated with a corresponding pair of the input pixel values. The apparatus may further include a halftone core coupled to the unpacker to receive the shifts and the average values from the unpacker and to generate pairs of output pixel values based at least in part on the received shifts and average values, wherein the output pixel values are for generating pixels of an image.

    摘要: A page printer stores a page processing procedure that includes code for converting display commands to a rasterized image and further stores display commands allocated to plural page strips of a page. The page includes N page strips. The printer includes a print engine adapted to print one page per X units of time, an auxiliary processor adapted to operate in conjunction with said page processing procedure and a main processor. The main processor is operable in conjunction with the page processing procedure and (i) determines an amount of processing time required to process each page strip of a page into rasterized image data; and (ii) for a page strip whose processing time exceeds X/N units of time, determines if sufficient time is available, once the print engine commences printing said page, to convert the page strip from display commands to a rasterized image before the rasterized image is to be rendered by the print engine. If yes, the main processor assigns the page strip to be processed by the auxiliary processor. Otherwise, if the page strip processing time does not exceed X/N units of time, the main processor processes the page strip.

    摘要: A method and apparatus for performing color plane adjustment are provided. In one embodiment, an apparatus comprises a set of inputs for receiving a first input value and a second input value in a color space. The apparatus also comprises a color plane adjustment component operative to adjust the first input value and the second input value by amounts that depend on a distance of the first input value and second input value, respectively, from a value of neutral gray in the color space. The apparatus further comprises a set of outputs for outputting the adjusted first and second values. A related method and computer program are disclosed. Other embodiments are disclosed, and each of the embodiments can be used alone or together in combination.
