Patent number: 7515664Abstract: Data is recovered in an asynchronous environment where a sampling clock is generated internally, and is not externally frequency locked, by using programmable delay modules each providing a number of delay tap outputs. To recover data, two of the delay modules are used with a first delay module designated as a monitor delay module to monitor the clock edge transitions, while a second delay module is designated as a data delay module that provides a data output. A controller provides for incrementing or decrementing the tap delay of both delay modules to assure clock data falls at the center of the monitoring window as determined using the monitor delay module. The controller further selects between the two delay modules as to which provides data and which is used as for clock edge monitoring when the clock edge transitions drifts to an edge of the monitoring window.Type: GrantFiled: April 21, 2005Date of Patent: April 7, 2009Assignee: XILINX, Inc.Inventor: Tze Yi Yeoh

Patent number: 7106901Abstract: This invention relates to a method and apparatus for image classification. More particularly, the present invention provides a technique to classify an image as a picture, a graphic or a mixed mode image. The classification is based on an approximation of a segmentation. The approximation is HVQ-LUT-based and outputs classification maps indicating whether pixels are background, text or pictures. Said classification maps are filtered to eliminate odd isolated samples and the resulting count of picture, text and background pixel is analyzed before concluding whether the image has pictorial, graphical or mixed contents.Type: GrantFiled: January 15, 2003Date of Patent: September 12, 2006Assignee: Xerox CorporationInventor: Ricardo L. de Queiroz

Patent number: 5418629Abstract: When the operating mode of a facsimile apparatus relates to only the reading of an original to be transmitted, coding, and storage into an image memory, the reading of the original, coding of the image signal, and storage of the image signal are executed at regular intervals. In the case where the operating mode relates to the case where not only the reading of the original, coding, and storage into the image memory are executed but also the communication, printing of the received image, or printing of a communication management report is simultaneously executed, the reader motor is rotated within a pull-out region asynchronously with the timing for the reading of the original, coding, and storage into the image memory.Type: GrantFiled: September 27, 1993Date of Patent: May 23, 1995Assignee: Canon Kabushiki KaishaInventor: Shigeo Miura

Patent number: 5239393Abstract: An image processing system has a reading device for reading an image of an original line by line, which repeats the reading operation at a predetermined cycle. A moving device moves an image reading position of the reading device in accordance with a driving signal. A driving device supplies to the moving device the driving signal for moving the image reading position of the reading device by a pitch line during a time period of the reading operation of a line. A computer generates a signal for instructing resumption of image reading by the reading device after interruption of the image reading. The driving device initiates supply of the driving signal to the moving device before the reading operation, upon reception of the image reading resumption signal generated from the computer.Type: GrantFiled: September 16, 1992Date of Patent: August 24, 1993Assignee: Canon Kabushiki KaishaInventor: Yukitoshi Takeuchi
