  • Publication number: 20100090007
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.

  • Patent number: 7614559
    Abstract: An imaging lens is positioned at an initial position, the image of a subject is sensed and an overall focus evaluation value representing the degree of focus of the image of the subject is obtained. Face detection processing is only executed if the overall focus evaluation value obtained is equal to or greater than a threshold value. The imaging lens is then moved to the next position and the process repeated. A range in which face images are detected at positions of the imaging lens where the overall focus evaluation value is equal to or greater than the threshold value is decided upon as a focusing range. A graph of face-area focus evaluation values representing degree of focus of the image portion of the face is obtained and the position at which this graph is maximum is decided upon as the in-focus position of the imaging lens.

    Abstract: Systems and techniques for using signal to noise ratio information to enhance bar code scanning accuracy. Noise information affecting bar code scanning operations is stored and a scan signal is monitored. Upon detection of a scan of a bar code, the signal strength of the scan signal is evaluated and signal to noise ratio values are computed. Signal to noise ratio information is used to favor or disfavor candidate decoding results. In addition, signal to noise ratio thresholds are set according to appropriate criteria. Decoding results are evaluated using the signal to noise ratio thresholds and accepted or rejected depending on whether the thresholds are met. In addition, thresholds for recognition of transitions based on peaks may be set based on expected noise affecting the scan signal, and allowed or excluded based on whether a rise from a negative peak, or fall from a positive peak, meets the threshold.

  • Patent number: 7527199
    Abstract: Methods and systems that protect the privacy of signatures on envelopes containing ballots sent through the mail are provided. The envelope for returning ballots by mail includes an electronic optical shutter that covers an opening in the flap of the envelope. The voter signs the back of the envelope in an area that will be visible through the opening in the flap (covered by the optical shutter) when the envelope flap is sealed. The optical shutter is opaque under static conditions, but will become transparent when power is supplied to it. When the envelope flap is sealed and no power is applied to the optical shutter, the voter's signature will be concealed by the optical shutter. Upon receipt at the registrar's office, the optical shutter can be powered, thereby rendering the optical shutter transparent, and the voter's signature can be viewed.

  • Patent number: 7527206
    Abstract: A digital-imaging based code symbol reading system comprising an image sensing array with a field of view (FOV), an illumination subsystem with an LED illumination array, an automatic illumination measurement subsystem, an illumination control subsystem, and programmed imager processor supporting an image-processing based illumination metering program. The automatic illumination measurement subsystem automatically measures the illumination level at a particular region of the FOV and determines the illumination duration necessary to achieve a desired spatial intensity in the detected digital image. The illumination metering program automatically analyzes and measures, in real-time, the spatial intensity distribution of the digital image and determines whether or not a corrected illumination duration is required or desired when detecting the next or subsequent digital images, during the current or subsequent object illumination and imaging cycle.

  • Publication number: 20090108069
    Abstract: A barcode reader converts an electric signal generated from reflection light received from a barcode to a differential signal by a differential processing unit, and detects an extreme of the differential signal by an extreme detection unit. An extreme validity determination unit determines whether the detected extreme is a valid extreme, and information on the extreme determined to be valid is once stored in a memory. On the basis of the information of the extreme stored in the memory, a barcode width data generation unit performs binarization processing. An inter-extreme time difference is measured to determine whether the extreme is a valid extreme or noise, and the extreme determined to be noise is not stored, such that the time required for processing and load are reduced.

  • Patent number: 7516896
    Abstract: A MEMs scanning device has a variable resonant frequency. In one embodiment, the MEMs device includes a flexible arm that extends from an oscillatory body. An electrical field applies a force to the flexible arm, thereby bending the flexible arm to change the moment of inertia of the oscillatory body and a secondary mass carried by the flexible arm. The shifted combined center of mass changes the resonant frequency of the MEMs device. In another embodiment, an absorptive material forms a portion of a torsional arm that supports the oscillatory body. The mechanical properties of the absorptive material can be varied by varying the concentration of a gas surrounding the absorptive material. The varied mechanical properties change the resonant frequency of the scanning device. A display apparatus includes the scanning device and the scanning device scans about two or more axes, typically in a raster pattern.

  • Patent number: 7513428
    Abstract: An imaging device including at least one imaging array and image formation optics that provide a field of view corresponding to the imaging array. At least one illumination module (which includes at least one source of coherent illumination) produces planar light illumination that substantially overlaps the field of view corresponding to the imaging array. Illumination control circuitry modulates the power level of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array to thereby reduce speckle noise in images captured by the imaging array. The illumination control circuitry preferably modulates the power level of illumination by controlling the number and/or duration of time periods corresponding to different power levels of illumination produced by the source of coherent illumination during each photo-integration time period of the imaging array.
