    摘要: An image sensor array system is addressable to enable readout of randomly selected image data from any one or more individual sensor cells, for any selected image area (13), or for the entire image area (15). The sensor array (16) is accessed by horizontal and vertical readout circuits (22 and 24) under the control of address signals from an address unit (20). Location signals, from a source (12), indicative of a selected image area (13) may be used by the address unit (20) to provide address signals representative of the location of a specific sensor cell or area (13) of the array including image data of interest. Under the control of the address signals, image data from cells at the intersection of array lines and columns are sampled by sampling devices (26-32) and provided as output signals representative of the selected portion of the image area at an output port (34). Simplified readout can be provided for oblique line components of images. Differing input bus widths enable different levels of cell or line selection.

    摘要: An extended working range dataform reader with reduced power consumption having a camera assembly and a circuit control board including game control circuitry and exposure control circuitry configured to set an initial gain value and an initial exposure period, respectively, resulting from a previous dataform reading session. Subsequent fields of image data are captured by the camera which are used to correct the gain and exposure relative to the initial values for gain and exposure period, thereby reducing the latency period for realizing correct values and reducing power consumption during power up. Furthermore, the gain control system and the exposure control system each utilize an open loop feedback such that successive fields of image data captured by the camera are utilized to calculate correct values, thereby reducing the latency time for realizing a correct value. Additionally, a reader module is provide for use in a dataform reader that emulates a laser module such that the dataform reader module can be readily integrated into existing laser-based dataform reading systems. Preferably, laser model emulation circuitry included in the dataform reader module emulates output of a laser scan module and a control circuit board in which the emulation circuitry is realized has an output port constructed and arranged to communicate with devices configured for use with a laser scanner.

    摘要: Dataform readers and methods provide operation with a sequence of overlapping exposure periods for successive lines of sensor elements of an array. Also, the exposure periods for successive lines of sensor elements, or successive subsets of lines, can be independently determined. In operation of a dataform reader illumination of a target area is turned on before exposure of the first line of sensor elements, each line of sensor elements is exposed by reflected illumination in an exposure period which overlaps with the exposure period of one or more other lines, and illumination is then turned off. Using a CMOS construction, for example, the level of image signals read from one line of sensor elements is referred to a look-up table to determine an appropriate exposure period for a subsequent line or lines of elements of an array. This process is repeated to achieve exposure periods adjusted for localized exposure conditions for each successive line or subset of lines of sensor elements.

    摘要: A machine readable code in a form such as a bar code uses self-addressed address/data packets which can be positioned in arbitrary orders and configurations. Additional benefits, such as ability to use extended scan angles for decoding and reduction in required code management data, also result from the self-contained nature of the address/data packet components of packet codes. A sequence of data is separated into units of data which are encoded in data portions of packets each also including an address portion which identifies the position of such data unit relative to the original sequence of data. The individual packets may then be positioned in a wide variety of configurations, rectangular and otherwise, with the individual packets in any order, sequential or otherwise. Even where packets are aligned in an extended row, the usable scan angle range is determined by the width to height aspect ratio of individual packets and not limited by the much higher aspect ratio of the row of packets. Methods and systems for encoding and decoding packet codes are described.

    摘要: The reading and decoding of two-dimensional bar codes in a bar code reader are simplified and field loading of different data character sets is enabled. Decoding of bar/space patterns of a bar code is simplified by deriving T-sequence data representative of the bar/space pattern and then processing a majority of the T-sequences directly into decoded values representative of the bar/space pattern. Dynamic loading of new data character sets fully or partially superseding a factory installed default character set correlation listing is enabled by use of loadable correlation listings keyed to foreign language characters, symbols, words or phrases relevant to particular applications. The loadable correlation listings can be encoded into a two-dimensional bar code and loaded via a reading of the bar code by the bar code reader.

    摘要: A two-dimensional bar code is used to identify a traveler's luggage, permitting the luggage to be tracked and, if desired be delivered to the traveler's ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding two-dimensional bar code is applied to the traveler's boarding pass. A two-dimensional bar code reader is used to read the boarding-pass bar code of each enplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an enplaned passenger. The boarding-pass bar code may take the form of an integrated passenger identification code for use by e.g., rental car companies, hotels, and the like.
