Abstract:
A method to compact a diffuse gray edge that is two pixels wide to a state where it is one pixel wide so that it may be well rendered with anti-alias rendering. The method identifies an observation window within continuous tone image data. The method then operates on the pixels within the observation window by: compacting horizontal features within the observation window; compacting vertical features within the observation window; and compacting corner features within the observation window.

Abstract:
A system for generating a warped contone image that compensates for beam scan trajectory distortions. The system includes an image buffer for storing a portion of a received contone image. An interpolation coefficient generator provides interpolation coefficients associated with a warped pixel within the warped contone image in response to an input identifying the warped pixel. A pixel interpolator is coupled to the image buffer and the interpolation coefficient generator and provides an output signal that identifies the warped pixel within the warped contone image. The pixel interpolator further retrieves pixels from the contone image stored in the image buffer using the interpolation coefficients and generates the warped pixel by combining the retrieved pixels into a single pixel value.

Abstract:
An apparatus and method that provide consistent output across a plurality of different hard copy output devices which may be included in a system comprising an image data source and a hard copy output device. The image data source supplies image data to a printable image data adjusting apparatus. The image data supplied may be in a device-dependent color space or a device-independent color space. If the image data is in a device-dependent color space, the printable image data adjusting apparatus first converts the image data into device-independent image data and stores it in memory as target image data. If the image data is already device-independent image data, the image data are simply stored in the memory of the printable image data adjusting apparatus as target image data. The printable image data adjusting apparatus then uses the target image data to generate printable image data. The hard copy output device uses the printable image data to generate a hard copy image.

Abstract:
A registration system for image data in a binary image path includes a registration parameter source, such as a preprogrammed memory or a dynamic device, which provides registration parameters to correct for registration errors from a predetermined reference likely or predicted to occur during image output. A warping processor is in data communication with the registration parameter source which applies a selected registration parameter to an element of the image data resulting in a warped data element, minimizing the effects of the registration error. The system optionally includes an image reducing device which receives groups of high addressable binary image data and converts them to a single pixel. The pixel is then provided to the warping processor. The warping processor applies the selected registration parameter, either static or dynamically selected, from the registration parameter source to the averaged single pixel producing a warped data element.
Method And System For Compensating For Scaling Artifacts In Mixed Raster Content (Mrc) Representations
An image processing method and system compensates for artifacts in scaling operations of mixed raster content data representations. In such data representations, a document is segmented into data portions generally segregated by data types. At least one of the segments is dilated so that upon scaling reconstruction, there are additional pixels available for interpolation operations, thereby avoiding artifacts caused by discontinuity.

Abstract:
This invention relates to a method and apparatus for segmenting an image using a combination of image segmentation techniques. More particularly, the invention is directed to an improved image segmentation technique for use in an image processing system that performs at least two distinct image segmentation processes on an image and combines the results to obtain a combined multi-layer representation of the image that can be suitably processed. In a specific example, a block based segmentation technique is performed on an image to generate a MRC (mixed raster content) representation—having foreground, background and selector layers. A pixel based segmentation technique is also performed on the image to generate rendering hints. The MRC representation and the rendering hints are then combined to obtain a four (4) layer representation of the image. The four layer representation is subsequently processed as required by the image processing system, e. g.
Led Bar Array High Addressable Imaging In 2-Dimensions
An imaging apparatus includes an input that receives a stream of image pixels such as high addressable bits, multiple bits per pixel or binary image bits representing an input image and a processor that processes and directs signals to an LED bar that selectively exposes areas of a photoreceptor. The exposed areas of the photoreceptor form a latent image, controlled by the processor, of areas of varied exposure based on surrounding pixels. The processor examines the pixels to determine an image structure beneficially adaptable to varied exposure and selects a pixel for varied exposure, such as increased or decreased exposure or altered timing to apply the pixel.

Abstract:
A photosensitive apparatus, such as scanner, includes a plurality of pixels, each pixel having associated therewith a set of photosensors, each photosensor filtered to record a primary color. The photosensors are exposed to light of each primary color separately, thereby deriving test signals. A cross-color correction factor for the pixel is derived from the test signals. The cross-color correction factor is used in processing signals output from the pixel when an image is being recorded, so as to isolate the effects of signal crosstalk between closely-spaced photosensors of different colors.
