This invention provides an extended infrared-sourced multi-touch screen, comprising: a display module; at least an infrared (IR) source set in adjacent to a display module as the light source of the multi-touch screen; at least a beam expander optical apparatus being responsive to the at least an IR source to form an IR flat-field line pattern; at least an IR receiver set corresponding to said at least a beam expander optical apparatus to receive IR light emitted by the at least an IR source and to receive IR light from an object when said display module being touched; and a positioning module being responsive to said at least an infrared receiver to process coordinate positioning after the touch action is detected by the at least an IR receiver.
摘要:
Preferably, test-patterns print on separate, multiple print-medium cards, each including a ramp with colors graded along a certain direction—and, superimposed on the ramp, a candidate add-on colorant. Ramps preferably are printed in so-called “customer colors”, common in snapshots and particularly snapshot regions that include sky. Positions or amounts of the candidate add-on colorant canvass a likely range of values that optimize camouflaging or suppression of a banding artifact (due to seams in the pagewide array) that is extended along the same certain direction. For each seam and each “customer color” used, an operator holds up several cards for comparison, selecting the best one to three. Operators thus can evaluate candidate colorant patterns in context of many different tones of the sky and other customer colors. Preferably banding suppression is integrated with linearization: at each seam a series of linearization tables is smoothly interpolated between measurement-based tables for adjacent inkjet dice.

Brightness of a plurality of pixels in a digital image is adjusted directly in a luminance-chrominance color space. Luminance and saturation are adjusted concurrently without changing hue of the pixels.
摘要:
An automatic system forms color LUTs (or LUT-forming data) for automated reference—typically in error diffusion (ED). A first aspect is for printers with six or more colorants. Three ramps, for different basic colorants, are photometrically measured; mainly just those results yield a transform from 3D color to system colorants. In a second aspect, some device-state candidate colors are chosen for black replacement. In a variant the choice is subject to (1) maintaining some chromatic colorant in each pixel with black; or (2) modifying use patterns to avoid alternative use of composite black vs. black; or (3) adjustments to allow for composite nonequivalence to black. A related third aspect allows replacement only if there is a given minimum amount of composite. In a fourth aspect, candidate states are dropped that have small changes in number of quanta per pixel, or no companion light colorant quantum with each dark one, best eliminating those with too many quanta of each or all colorants. In a related fifth aspect, one state is assigned to each major entry based on, at a gamut surface except at the dark end, favoring states nearer the surface over those nearer a desired major entry; and at the neutral axis, especially its dark end, favoring real black. Other assigning is best done by entry nearness. In a sixth aspect preferably 1D LUTs are formed for finding major entries based on an input-color spec, not monotonic in entry assignment to indices; precomputed ED distributions attach to indices. In a seventh aspect a state LUT formed to access states based on input specs is used to print nominal neutral colors and measured results used to adjust access. In an eighth facet related to the first, the ramps correspond to fundamental combinations of single colorants, e. g. secondaries.
摘要:
Disclosed is a new printing apparatus and process for inkjet printers which incorporates spectral modeling of ink mixing and the technology of halftoning in device-independent color space. In addition no colormap building or color mapping processing is necessary, because color correction is conducted in device-independent space and is built into the halftoning process. also disclosed is an automatic self-calibration by the printer without user intervention or user preferences by using an optical sensing unit on the printer. The procedure corrects for print cartridge to print cartridge variance, and variance of print cartridges over time and also provides for faster processing of color images.
