  • Patent number: 6243499
    Abstract: The present invention is a method and apparatus for the identification and tagging of antialiased pixels within regions of an image. The techniques described improve the recognition of fine gray features and enable the detection of both black and white features on high and low contrast backgrounds. The system relies on the establishment of the sense (positive/negative) of an image by first using a histogramming operation. Once the sense is determined, a plurality of logical channels are used to select a threshold, binarize a region of the image, generate a vector representative of the region, and to process the vector to identify whether an antialiased pixel is present therein. Subsequently, the output of the channels is logically combined to produce an antialias tag.

  • Patent number: 6173750
    Abstract: A direct die feeder picks known good die from a wafer and places them on a conveyor belt, which conveys the die to a pickup location. Frame (111) supports a wafer (105) which is a wafer that is sawed while adhered onto a flexible film, which is then stretched and mounted in a ring (110). A fork member (125), on which a pick head (150) is mounted slides along a horizontal axis and frame (111) slides along a vertical axis to allow the pick head (150) to access any die from the wafer. A camera (160) is directed downward at a 45° mirror (162) adjacent to the pick head to capture images of the wafer and determine the precise locations of die and qualify them. The pick head (150) can pick die from the wafer and place them directly on the conveyor belt (170) in the conventional orientation, or pass the die to a flip head (140) which then shifts to the left and lowers the die down past the pick head, placing the die on the conveyor belt in the flipped orientation.

  • Patent number: 6133932
    Abstract: The present invention is a method and apparatus for modifying line synchronization signals that drive at least one secondary image exposure device in a multicolor printing or reprographic system. The ability to alter the line synchronization signals enables the accurate registration of a multiple color images on a photoconductor in response to detected photoreceptor motion. More specifically, the first color image is deposited on the photoreceptor using a servomotor control system to control photoreceptor velocity as a function of the desired raster line spacing, or the frequency at which the individual raster lines are deposited. All subsequently added colors in the single-pass printing system are added under the control of phase-locked loops, wherein the line synchronization pulses are produced as a function of the photoreceptor speed, to correct for variations from the nominal photoreceptor velocity.

  • Patent number: 6009192
    Abstract: The present invention is a method for the color correction of digital images that have been compressed. In a preferred embodiment, aspects of the color correction are carried out on the compressed image data to improve computational efficiency. One of a number of alternative methods is employed to accomplish the color correction on lossy or losslessly compressed images. The color transformation process accomplishes color correction on compressed image data in conjunction with compression or decompression operations. A second, simplified phase of the color correction may be applied subsequently to the decompressed image data in certain embodiments. Accordingly, the technique has application to any number of color imaging systems, including digital printers and copiers where there is a necessity to color correct compressed digital images.

  • Patent number: 5867598
    Abstract: The present invention is a method and apparatus for the processing of images that have been compressed using a discrete cosine transform operation, and particularly JPEG compressed images. In a preferred embodiment, the rotation of image blocks is accomplished by sign inversion and transposition operations to accomplish intrablock operations. Subsequently, one of a number of alternative methods is employed to accomplish the same image processing on an interblock level, thereby enabling the rotation or mirroring of compressed images. The two stage process allows the use of either a standardized JPEG system with enhancements or a hybrid processing method, thereby accomplishing the image processing in conjunction with compression or decompression operations and minimizing the need for large memory buffers to accomplish the image processing.
