摘要： A plurality of solid-state imagers is mounted in a reader, such as a bioptical, dual window, point-of-transaction workstation, for capturing illumination light returning along different fields of view from indicia. A controller controllably activates the imagers over respective exposure time periods during which the indicia are illuminated to produce electrical signals indicative of the indicia being read, processes the electrical signals to read the indicia, and controls the exposure time periods to be nonconcurrent to prevent interference among the imagers.

摘要： An automatic focusing system for an imaging-based bar code reader. The automatic focusing system employs a two step process for moving a lens of an imaging system along its path of travel such that a sharp image of a target bar code is projected or focused onto an imaging system pixel array. The first step is laser ranging which utilizes a laser beam for range finding. Laser ranging determines a distance between the imaging system pixel array and the target bar code. Given the determined distance, the automatic focusing system moves the lens to a suitable position for imaging the target bar code. If ambient conditions prevent laser ranging from properly working, the second step is focus analysis. Focus analysis involves moving the lens in accordance with a search routine and analyzing image frames of the target object to find a suitable focus position.

摘要： An optical code reading system and method are provided for reading and decoding an optical code. The system includes a plurality of light sources, a color image sensor, a processor and a decoder. Each light source produces a unique wavelength/color of light to illuminate the optical code, such as a direct mark optical code. The image sensor detects the reflected light from the optical code and generates an integrated multi-colored image. The processor separates the integrated image into individual color channels, where each color channel includes data representative of the imaged optical code in one color. The processor analyzes the contrast for each color channel and determines which color channel has the optimum contrast. The data corresponding to the color channel having the optimum contrast is then decoded by a decoder.

摘要： An apparatus for, and method of, imaging a target presented to a bi-optical, dual window, point-of-transaction workstation utilizes multiple imaging modules individually mounted for individual installation on, and individual removal from, a motherboard. Each module includes a solid-state imager having an array of light-sensitive sensors for capturing return light from the target over a field of view; a local controller externally of the imager for controlling the imager, for storing image data corresponding to the captured return light, and for interrogating the stored image data; and a daughterboard on which the imager and the local controller are both commonly mounted.

摘要： An imaging module is supported by a housing of a reader for electro-optically reading indicia. The imaging module includes a solid-state imager having an array of image sensors for capturing return light from the indicia during reading. A laser scanning module is also supported by the housing and includes a scanner for scanning at least one of a laser beam from a laser and a field of view of a light detector in a scan pattern across the indicia during reading. A controller is operatively connected to the modules, and is operative for preventing reading interference between the modules during reading.
