摘要： A method and apparatus for generating a half-tone version of an image represented by a first set of digital data defining the colour content of abutting pixels of the image at a first resolution. The apparatus comprises a radiation beam generator (8); a recond medium support (11), wherein the radiation beam and the support are relatively moveable such that the radiation beam scans a record medium (10) mounted on the support in a series of abutting scan lines; a radiation beam modulator (7) for modulating the radiation beam in response to a control signal (CS); and a control signal generator (5) for generating the control signal. The radiation beam is modulated selectively to expose a record medium on the support (11) at a second, finer resolution, the control signal generator (5) being adapted to interpolate the second set of digital data from the first set of digital data and to generate the control signal by comparing the second set of digital data with half-tone information.

摘要： A method of compressing digital image or image-like pixel data. The method comprises carrying out the following steps on small blocks of pixels:a) determining the differences between digital values of adjacent pixels in the block to define respective link weights;b) determining a tree connecting all the pixels in the block such that the sum of the link weights in the tree is a minimum;c) dividing the tree into segments by removing links with weights greater than a threshold value, so dividing the block into segments of linked pixels;d) generating a segmented representation of the block by setting the values of all pixels in each segment to a single, respective, representational value; ande) compressing the segmented representation to generate compressed data.

摘要： In a method of producing a digital half-tone representation of an original image, wherein the representation is constituted by an array of output cell values representing the colour content of pixels of the original image, cell values are determined for successive output cells, for which cell values have not previously been determined. An output cell value is generated with reference to an input cell value related to the colour content of a corresponding pixel in the original image, and any error values propagated from previous iterations. Where the output cell value satisfies a predetermined condition, the effective colour content of a neighbourhood of previously determined output cell values is determined by addressing a look-up table containing a single value for each neighbourhood. An error value constituted by the difference between the effective colour content and the corresponding input cell value is determined and propagated for use in subsequent iterations.

摘要： A method of generating an output device control signal having portions representing the content of pixels of an image including at least two types of image content, in which data defining the content of each pixel of the image at a lower, first resolution and a higher, second resolution are passed respectively through a pair of processing paths, one corresponding to each image content type. A binary control signal is generated from the first resolution data in the first path by applying a stochastic screen. The binary control signal resulting from the stochastic screen is adapted to conform with the data at the second resolution, and the output device control signal is generated by combining data from the two processing paths.
