摘要： An a data input system includes an encoded pad having position encoding and a data input device adapted to image a portion of the encoded pad to determine position and orientation of the data input device relative to the encoded pad. The encoding pad includes a plurality of correlation windows. Each correlation window includes a primary encoding marker in form of vertical line segment and a set of secondary encoding markers in form of diagonal line segments, at least one diagonal line segment intersecting the vertical line segment at an intersection angle. Spacing of the diagonal line segments encodes the X-axis position of the input device relative to the encoding pad. Intersection angle encodes the Y-axis position of the input device relative to the encoding pad. Angle of the primary encoding marker vertical line segment within the frame of the captured image encodes the angular orientation of the input device relative to the axes of the encoded pad.

摘要： An image processing system subtracts dark noise out of images based on a dark noise scale factor. The image processing system includes an image sensor for capturing a current image and producing current image data representing the current image. The current image data includes both a dark noise signal and an image signal. The dark noise scale factor for the current image is estimated from the current image data and reference image data representing a reference dark noise signal. The reference dark noise signal is scaled by the dark noise scale factor to produce a scaled dark noise signal from which the current image data is subtracted to produce the image signal.

摘要： An image processing system uses centralized image correction data to process digital images. The image processing system includes a centralized database for storing image correction data for imaging devices. An image processor that receives image data representing an image captured by one of the imaging devices accesses the centralized database with a key associated with the imaging device to retrieve the image correction data for the imaging device. The image processor processes the image data using the retrieved image correction data to correct the image data by reducing various noise components in the image.

摘要： Generally, the embodiments are directed to circuits and methods for time stamping an event at a fraction of a clock cycle. A time stamping circuit comprises two or more detection circuits. The detection circuits receive an event-in signal and generate event signals based on a clock phase at which the event-in signal was received. A decoder receives the event signals and outputs an event-out signal and a time stamp that represents the phase at which the event-in signal was detected. By time stamping the event-in signal to a phase division, the time stamping circuit detects event signals that occur at a rate faster than the clock cycle.

摘要： Generally, the embodiments presented are directed to circuits and methods for triggering an event at a fraction of a clock cycle. A triggering circuit can comprise two or more input circuits that output an event signal. The event signal is received by one of two or more delay circuits that trigger the event signal at a predetermined phase of the clock cycle by moving the event signal from a first clock domain to another clock domain. By triggering the event at a phase division, the triggering circuit outputs signals at a rate faster than the clock cycle.

摘要： Reduction of dust contamination in optical mice. Trapped charged particles within an optical element result in a surface charge on the optical element, the surface charge reducing the attraction of dust to the optical surface. Charged particles may be trapped in the optical element, or in a coating on the element. Irradiation from an alpha source or ion implantation techniques may be used.

摘要： Reduction of dust contamination in optical mice. Optical elements are made electrically conductive, reducing static charges which attract dust particles. Plastic optical elements may be made conductive through the use of conductive polymers. Optical elements in plastic or glass may be made conductive by coating them with materials which are conductive but pass wavelengths of interest. Multi-layer coatings may be used. Indium tin oxide is a coating of interest, and coatings of metals such as gold, silver, tin, or zinc, and their compounds, may be used.
