    摘要: A computer assembly having a host computer and a detachably attached computer expansion module. The computer expansion module includes a 2D imaging module, and may include short range imaging optics. In a “picture taking” mode actuated by input into the host computer, the expansion module captures an image, and without launching a decoding algorithm, sends the captured image to the host computer which displays the image on an integrated display of the host computer. In a “decode” mode actuated by input to the host computer, the expansion module captures an image, executes a decoding algorithm, and sends a decoded out message to the host computer, which displays the decoded out message on an integrated display of the host computer.

    摘要: A method for decoding a decodable symbol using an optical reader having a 2D image sensor that is configured to operate in a partial frame capture operating mode. In a partial frame operating mode, the reader clocks out and captures at least one partial frame of image data having image data corresponding to less than all of the pixels of an image sensor pixel array. In one embodiment, the reader operating in a partial frame operating mode captures image data corresponding to a linear pattern of pixels of the image sensor, reads the image data, and attempts to decode for a decodable bar code symbol which may be represented in the image data.

    摘要: The invention relates to a microprocessor-based decoder board for an optical reader having in one embodiment a plurality of imaging modules that provide frames of image data having a plurality of formats. In one method for operating the decoder board of the invention, and a multiple imaging module reader comprising the decoder board, a frame of image data captured by a selected imaging module is decoded. The decoder board determines the format of the frame of image data from information about which of the plurality of imaging modules provided the frame of image data or from information about the frame of image data, activates as necessary a command to prepare the decoder board to decode the frame of image data according to the format provided by the imaging module, and performs the decoding.

    摘要: An exposure control apparatus for use with optical readers, such as bar code readers, which utilize photosensitive image sensors. An illumination signal generating circuit generates an illumination signal having a magnitude that varies in accordance with the time averaged value of the illumination level at the image sensor. A window detecting circuit periodically samples the illumination signal to determine if that signal is or is not within a window of acceptability. Exposure period determining circuitry uses the output of the window detecting circuit to upwardly or downwardly adjust the value of a control variable as necessary to cause the illumination signal to approach, enter and remain within the window of acceptability.
