摘要： Printing apparatus and method particularly suited to provide a hardcopy of an image which is produced by medical imaging equipment or the like. The apparatus produces hardcopy consisting of pixels whose size can be changed by area modulation to suit image tonal content and detail while still maintaining a large number of gray levels per area modulation cell (pixel). Preferably, the same area modulation patterns representing pixel tonal values are used for printing pixels of different sizes.

摘要： A method and an apparatus determines a geometry of a scene by projecting one or more output image into the scene, in which a time to project the output image is t1. Input images are acquired of the scene, in which a time to acquire each input image is t2, and in which t1>t2 and in which the input image includes a distinguishable stripe of pixels with an edge due to t1>t2. An amount of distortion of the edge is measured from a straight line to determine a geometry of the scene.

摘要： Techniques are disclosed for performing color correction in a color printer. An RGB test image is printed to produce a printed calibration image. Colors in the printed calibration image are measured and compared to expected color values. A color corrector generates a printer lookup table (LUT) based on this comparison. The LUT may be generated based on models of the printer's print engine and previous LUTs. The color corrections are applied to subsequent print jobs to improve the quality of color output. Color measurement and correction may be performed using a closed-loop system contained within the printer that includes a color measurement device (such as a scanner) and a computer.

摘要： A method is provided for providing the same amount of energy to each print head element in a thermal printer during each print head cycle used to print an image, regardless of the number of print head elements that are active during each print head cycle. The desired amount of energy may be provided to a plurality of print head elements that are active during a print head cycle by delivering power to the plurality of print head elements for a period of time whose duration is based in part on the number of active print head elements. The period of time may be a portion of the print head cycle.

摘要： An adaptive halftoning method where the difference between a digital image and a filtered digital image is introduced into the system on a pixel by pixel basis is disclosed. In this method, each input difference pixel has a corresponding error value of the previous pixel added to the input value at a summing node, resulting in modified image difference data; the modified image difference data is passed to a threshold comparator where the modified image difference data is compared to a threshold value, the threshold value varying according to the properties of the digital image, to determine the appropriate output level; the output level is subtracted from the modified image difference value to produce the input to an error filter; the output of the error filter is multiplied by an adaptation coefficient, where the adaptation coefficient varies according to the properties of the digital image, to generate the error level for the subsequent input pixel; and, the cyclical processing of pixels is continued until the end of the input data is reached.
