Abstract:
An imager (10) with a two-dimensional array of sensors (36) processes illumination data from a subset of the sensors (36) located within a selected region of the image to determine imager settings ppor to acting upon a full frame of data In this manner, imager settings can be quickly determined by transferring and examining only the segment of the sensor array data
Abstract:
A scan engine (52, 66) for imaging a target object (30) comprises a photosensitive circuitry (58, 76) located within the scan engine (52, 66) for capturing an image reflected from a target object (30) to the scan engine (52, 66). A communication interface (60, 78) is disposed within the scan engine (52, 66) and coupled to the photosensitive circuitry (58, 76) for communicating an undecoded signal (62, 80) to a remote device (14) over a digital serial interface.
Abstract:
An imager with a two dimensional array of sensors processes illumination data from a subset of the sensors located within a selected region of the image to determine imager settings prior to acting upon a full frame of data. Li this manner imager settings can be quickly determined by transferring and examining only the segment of the sensor array data.
Abstract:
An imaging scanner with a two dimensional array of sensors analyzes data from a segment of the array to detect if one or more indicia conditions is present that would prevent a successful decode based on data in the segment. In this manner, if decoding the indicia using data from the segment of array data is not possible, an enlarged frame of array data can be sought for decode when necessary while one-dimensional and simple two-dimensional barcodes can be quickly processed by loading and decoding only the segment of the array.
Abstract:
An imaging-based bar code reader that includes an imaging and decoding system. When used on a stand to image documents, typically neither the stand or document is moving. Therefore blurring due to motion is not an issue. A sensor detects when the scanner is mounted to a stand. When commanded to take an image the scanner electronics and software modifies an auto-exposure process to minimize gain and lengthen exposure. This modification results in the scanner that is effective for scanning bar codes and yet also takes excellent pictures when mounted to a stand.
Abstract:
An imaging module for electro-optically imaging a target, includes an energizable illuminating light source for illuminating the target with illumination light for return from the target, an energizable solid-state imager for capturing return light from the target, and a controller for energizing the imager during an exposure time period to capture the return light at a frame rate, for deenergizing the imager during a non-exposed time period, and for energizing the illuminating light source not only during the exposure time period, but also during the non- exposed time period, to produce a plurality of illumination light pulses at an illumination rate that enables the human eye to perceive the illumination light pulses as substantially continuous. The illumination rate of one or more of the illumination light pulses produced during the non- exposed time period is substantially independent and decoupled from the frame rate.
Abstract:
An imaging scanner with a two dimensional array of sensors analyzes data from a segment of the array (115) to detect if one or more indicia conditions is present that would prevent a successful decode based on data in the segment (125) In this manner, if decoding the indicia using data from the segment of array data is not possible (130), an enlarged frame of array data (160) can be sought for decode when necessary while one-dimensional and simple two-dimensional bar codes can be quickly processed by loading and decoding only the segment of the array.
