摘要:
Interleaving multiple logical data streams into one physical data stream reduces overhead required to process the multiple logical data streams. Multiple arrays of data values are interleaved into a combined array of data that simulates a frame of data for input to a data port such as a video port. Revised timing and synchronization signals are provided to permit transmission of the combined array according to video data port protocol. The processor includes instructions for locating the various arrays of data values within the combined array.

A scanner with a two dimensional array of sensors generates an aiming pattern that is concurrently used as illumination for a segment of the array. In this manner, one-dimensional and simple two-dimensional barcodes can be quickly processed by loading and decoding only the segment of the array.

A target is illuminated with high intensity light pulses to make the target appear stationary to a solid state imager of an imaging reader to improve reader performance at high swipe speeds of the target.
摘要:
A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.
摘要:
Methods and apparatus for improving direct part mark dataform decoding using a scanner comprising a processing unit, an optical module and an imaging sensor with an extended dynamic range. The scanner captures data to obtain an extended dynamic range image for analysis. In one embodiment, the sensor is sensitive to more than eight bits per pixel and in other embodiments multiple exposures are taken. Further in alternate embodiments, the scanner comprises a pass-band filter that passes the light emitted by an illumination module.

摘要:
A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.
摘要:
Methods and apparatus for illuminating objects comprising asymmetrically illuminating an object using an illumination medium on one side of an optical module of an information capturing module, capturing an electronic representation of the object and decoding the electronic representation of said object. In alternate embodiments, the scanner successively illuminates the object from a plurality of different angles until the object and/or dataform is decoded. The illumination medium can be external to the information capturing module.
