摘要： There is described an indicia reading terminal that can be operative to process a frame of image data for attempting to decode a decodable indicia. A frame can be a frame that is among a succession of frames for subjecting to processing subsequent to and during a time a trigger signal is active. Such a succession of frames can include zero or more binned frames, zero or more unbinned frames, zero or more windowed frames, and zero or more unwindowed full frames. An indicia reading terminal can also include a variable focus imaging lens. Control of the variable focus imaging lens can be provided so that during an exposure period for a binned frame the variable focus imaging lens is set to a short range focus setting and further so that during an exposure period for a windowed frame the variable focus imaging lens is set to a long range focus setting.

摘要： There is provided in one embodiment an indicia reading apparatus with enhanced functionality which can filter image data prior to the capture of image data into an image frame memory for further processing. In one aspect the indicia reading apparatus can have an image sensing and processing circuit that can contemporaneously output, on respective first and second interfaces, both filtered and raw pixel values so that both filtered and raw frames of image data can be captured contemporaneously for further processing. Filtered and raw frames of image data or pixel values can also be serially output through a single interface in an interleaved manner. An image sensing and processing circuit which outputs either or both raw and filtered pixel values can be provided on a single integrated circuit. In another aspect an image sensing and processing circuit can be provided that develops data indicating a location of a decodable indicia representation within image data prior to capture of a frame of image data into an image frame memory so that when pixel values are first addressed for further processing, a decodable indicia representation such as a bar code representation has already been located. By processing of image data within an image processing circuit prior to capture into an image frame memory a trigger to read time (TTR) can be reduced.

摘要： An image sensor array system is arranged to enable oblique access for readout of image data from a stepped pixel pattern of sensor cells. The stepped pixel pattern represents an oblique line component of an image portion containing a 2-D bar code or other dataform. An obliquely aligned bar code image can thus be read out along oblique lines which follow rows of bar code elements traversing the elements. 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 portion (39) may be used by the address unit (20) to provide address signals representative of the stepped pixel pattern for a particular oblique line component. 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 oblique line component. The output signals are then usable for decoding the bar code or other dataform.

摘要： By providing subpixel accuracy in the detection of the position of an element of a pixel data image, the invention makes possible reductions in scanner and storage resolution of the order of 65 percent or greater for two-dimensional applications. Methods use normalized gray level values to determine the extent of coverage of an image cell by individual pixels. By then applying such gray level values of a plurality of successive pixels to a preconstructed lookup table, ambiguities are resolved to determine the position of cell edges. The cell edge data can be used to determine cell position or used directly in edge-based bar code decoding techniques. Cell position data is used for construction of a virtual image of a bar code or other dataform of interest and virtual image information may then be used for purposes of decoding the bar code or other dataform. For two-dimensional applications, the gray level values of a plurality of successive pixels, as referred to, may be implemented as a sliding window of three such gray level values along successive lines in a first dimension which are applied to a lookup table, followed by repetition for successive lines in a perpendicular dimension, to derive cell edge data for both dimensions.

摘要： Line-by-line dataform readers and methods are enabled to operate with reduced buffer memory capacity. Storage and retention of image data are controlled on an interactive basis by concurrent analysis while lines of image data are coupled from a linear scanner. In a first embodiment lines of image data are analyzed for recognition of a feature unique to a type of dataform. Upon successful feature recognition a series of earlier and later lines of image data adequate to include a complete dataform image are retained in memory for decoding purposes. Prior to successful feature recognition, as lines of image data exceeding a limited memory storage capacity are received the earliest stored lines are discarded on a first-in-first-out basis. In a second embodiment, a buffer memory has a storage capacity adequate to store only a partial dataform image. Upon successful dataform feature recognition the type and size of the dataform are determined and decoding of the earliest lines including dataform image data is initiated, before the full dataform image is stored. As decoding progresses, the earliest lines of dataform image data are discarded as later lines of dataform image data are still being coupled from the scanner. Cost and power usage are lowered by reduction of required memory capacity.

摘要： A bar code reader system includes a record, a bar code reader, a decoder, a processor, a transferring element, and a printer. The record includes a substrate with an information area containing first data removably encoded on the substrate in an error-correctable machine readable format and text. The bar code reader converts the first encoded data from the record into electrical signals which are decoded by the decoder. The processor encodes second data entered through a keyboard, and generates transfer drive signals for controlling the transfer of the second encoded data onto the record. The transferring element detects the presence of the first encoded data on the record, and in response to the drive signals when the first encoded data is present on the record, subjects the record to an erasing operation to remove the first encoded data. The printer then prints the second encoded data on the record.

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.
