Methods and apparatus for proofing (644) a variable document intended for printing are disclosed in which a GUI (2000) is configured to allow user manipulation of layout rules associated with content containers within a template for variable document generation. Selective proofing (2100) involves proofing a plurality of variable data documents each formed from a common layout in which variable data content is placed into containers having locations and sizes within the layout and defined by layout rules. Measures of variation (2103, 2106) and measures of deviation (2109, 2110) are calculated. The measures of deviation are processed (2112) to give a deviation value. Once completed for each document, the deviation values of the documents are compared (2114) to identify at least one group of the documents for presentation for further assessment. Live proofing includes creating a layout (2002) for a variable data document based upon a template established in the GUI. A container (2010) is set in the template to form the layout, which is then modified to thereby generate an exemplary document by placing exemplary content into the container, wherein a dimension of the container and / or a position of the container are varied based upon a property of the placed content. The exemplary document is displayed in the layout via the GUI to enable visual proofing by the user.

Methods and apparatus for variable document printing are disclosed in which a graphical user interface is configured to allow user manipulation of layout rules associated with content containers within a template for variable document generation. One method involves laying out (626) container objects (407, 408) forming part of a template (624) intended for a variable data document. The objects each have a rectangular boundary in two-dimensional space, and the method comprises detecting an operation (628, 2800) to modify a position of at least one edge of at least one of the objects. Then, rules of association between edges of the objects having a corresponding orientation to the one edge are identified. A position of at least the one edge is then modified whilst observing the rules of association between all the correspondingly oriented edges. Finally an objective function derived from the rules of association between the correspondingly oriented edges is minimized (3009) to thereby balance a layout of the objects in at least the dimension of modification. Other methods involve maintaining the objective function for a group of edges, the addition and removal of constraints in respect of correspondingly oriented edges, the removal, addition and then removal of constraints in modifying the width of a container, the calculation of text container sizes, and the creation of tables, particularly for text containers.

An image desired to be reproduced is scanned to determine its video pixel gray values. A histogram generator generates a histogram distribution representing a frequency of the gray values. The histogram distribution is analyzed to determine a background peak gray value of the image and a standard deviation of the histogram distribution based on a Gaussian approximation. A thresholding circuit dynamically adjusts the background peak value based on the standard deviation and a selected scaling factor to generate a background threshold value. The background threshold value expands a range of background gray values in the image which are eliminated during image reproduction. Eliminating substantially all background gray values improves the quality of the reproduced image.

Techniques are disclosed for performing thermal history control in a thermal printer in which a single thermal print head prints sequentially on multiple color-forming layers in a single pass. Each pixel-printing interval may be divided into subintervals, which may be of unequal duration. Each sub-interval may be used to print a different color. The manner in which the input energy to be provided to each print head element is selected may be varied for each of the subintervals. For example, although a single thermal model may be used to predict the temperature of the print head elements in each of the subintervals, different parameters may be used in the different subintervals. Similarly, different energy computation functions may be used to compute the energy to be provided to the print head in each of the subintervals based on the predicted print head temperature.

A technique for generating high-resolution bitmaps from low-resolution bitmaps. A low-resolution bitmap is magnified to form a magnified image. Edge detection is performed on the magnified image to find high contrast edges. A plurality of image patches of the magnified image are generated. These images patches are analyzed by performing connected components analysis on each of them using the high contrast edges to produce a plurality of foreground and background decisions determining whether a portion of an image patch is a background or a foreground region. Then the contrast of one or more pixels in each of the plurality of image patches is enhanced based on the foreground and background decisions. Finally, the system and method of the invention combines the luminance of the enhanced output pixels with the color values generated by the magnification algorithm. This produces a high-resolution bitmap from the contrast-enhanced pixels.

Disclosed herein is a method of storing and of progressively transferring a still image so that it can be conveniently previewed during the transfer and so that a user can terminate the transfer at an early stage if the image turns out to be undesirable. The methods of the invention include transforming the image into a plurality of decomposition levels using a discrete wavelet transform. Each decomposition level comprises a plurality of subimages which allow reconstruction of an image representation of the still image. The decomposition levels are transmitted beginning with a base decomposition level providing a low level of image resolution and then proceeding with decomposition levels providing increasingly higher levels of image resolution. Within each decomposition level, rows of the various subimages are arranged or interlaced together in contiguous blocks, so that all data for a single row, at a single decomposition level, is transmitted together. At the receiving end of the transfer, the row blocks are reconstructed and displayed as they are received. The invention enables the initial display of a low resolution image which is gradually updated and sharpened, on a row-by-row basis, until a desired high resolution is achieved. The user may terminate the transfer at any point.

An adaptive image tone mapping curve based on perceptual preference guidelines is generated as a sigmoidal function, in which the sigmoidal function parameters (slope and shift) are determined by original image statistics. Tone curves generated for different images each have a smooth sigmoidal shape, so that the tone mapping process does not change the image histogram shape drastically. The sigmoidal function has the form: <math-cwu id="MATH-US-00001"> <number>1< / number> t it ( x ) = 100 1 + exp it ( - alpha it ( x / 100 - beta ) ) , <mathematica-file id="MATHEMATICA-00001" file="US20020171852A1-20021121-M00001.NB" / > <image id="EMI-M00001" wi="216.027" he="18.96615" file="US20020171852A1-20021121-M00001.TIF" imf="TIFF" ti="MF" / > < / math-cwu> where alpha is the slope parameter and beta is the shift parameter. The input value x in the sigmoidal function varies in the range [0, 100], because the tone curve is generated on an L* scale, which has values from 0 to 100. The sigmoidal tone curve calculation can be implemented efficiently using simple arithmetic operations by pre-calculating and storing various factors used in the calculation of alpha and beta and by pre-generating a pair of fixed tone curves with two extreme slopes and interpolating between the curves.
