摘要： Vector halftoning and error diffusion are combined to provide a quantization method that yields high quality rendered images while demanding fewer system resources. For instance, the method is tolerant of resolution reductions in secondary or auxiliary channels to the vector halftoning process. Accordingly, these secondary pixel data channels can be sub-sampled and/or bit-depth reduced for transmission bandwidth conservation and/or reduction in data storage requirements. Restoring the resolution of the low resolution channels provides estimated image data to arrange or align with high resolution target channel data for the vector halftoning process. Error from marking decisions generated by the vector halftoning process is diffused to neighboring unprocessed pixels. The method also allows for the use of a small vector halftone threshold array while providing quantized images with fine texture and wide color gamuts. In some embodiments error diffusion is distributed according to vector error diffusion.

摘要： This disclosure provides methods, apparatus and systems to generate vector halftone data for rendering an image on an image output device. According to one aspect, a method generates vector halftone data as a function of contone pixel data for a given colorant at its nominal resolution and contone pixel data for the other colorants at a relatively lower resolution.

摘要： The present invention is a method for antialiased tagging (AAT) applied coincident with an antialiasing operation. First, tagging methods for identifying antialiased pixels are described, the methods being employed separately or in concert with one another and focusing on pixels having a plurality of neighboring pixels that are near the extremes of the range of pixel levels (e.g. saturation and background). After tagging antialiased pixels, a preferred rendering method is optionally determined and is optionally included with the antialiased tagging information. Once tagged, said tag including the preferred rendering method, the pixel data and tag are then passed to a rendering processor and placed into a form suitable for binary printing.

摘要： A system for enabling depth perception of image content in a rendered composite image, wherein illuminant/colorant depth discrimination encoding provides encoding of first and second source images in a composite image, for the purposes of subsequent illuminant/colorant depth discrimination decoding. Composite image rendering allows for rendering the composite image in a physical form. Illuminant/colorant depth discrimination decoding allows recovery of the first and second source images, thus offering to an observer the perception of spatial disparity between at least one of the recovered source images and some or all of the remaining image content perceived in the rendered composite image.

摘要： A system and method for printer control and color balance calibration. The system and method address the image quality problems of print engine instability, low quality of color balance and contouring from the calibration. The method includes defining combinations of colorants, such as inks or toners that will be used to print images, defining a desired response for the combinations that are to be used and, in real time, iteratively printing CMY halftone color patches, measuring the printed patches via an in situ sensor and iteratively performing color-balance calibration based on the measurements, accumulating corrections until the measurements are within a predetermined proximity of the desired response. The calibration is performed on the halftones while they are in a high quantization resolution form.

摘要： The present invention is a method for antialiased rendering (AAR) of an image. First, tagging methods for identifying antialiased pixels were described, the methods being employed separately or in concert with one another. After identifying AAR pixels, a fill order is determined and applied using a fill order algorithm that preferably employs a pixel window that is a subset of the larger window employed for pixel identification.

摘要： Disclosed is a method for processing raster image data and determining via a reference device (e.g., LUT), an amount of marking medium (toner, ink) to be used for printing a document. Then billing costs based on the amount of medium is determined. In particular, a calibration method may be performed on an apparatus to determine the amounts of medium used for that particular apparatus. The calibration method includes printing pages with test patches for a plurality of colors at a particular dot value (or density), and weighing similar printed test pages so that the amount of medium used to print colors at particular dot values is determined by subtracting a weight of the pages before printing from the weight of the printed test pages. The change in weight (or mass) of the medium is used to populate the reference device for that apparatus.
