    摘要: The invention relates to a bar code reading device of the type having an imaging assembly including a two dimensional image sensor and which may be moved between varying positions, orientations and angles relative to a substrate. In one embodiment a bar code reading device can be used to obtain an area electronic representation of a substrate including bar code indicia and a signature, and can output an area representation including a representation of a signature. In another embodiment, the bar code reading device can process and output a processed area electronic representation to an output destination. In one embodiment an output destination to which a bar code reading device outputs a processed area electronic representation is a display.

    摘要: In the present invention, the control unit of an optical reader analyzes image data being generated by the imaging element of the reader and changes the mode of operation of the reader if the image data indicates that machine readable indicia, such as a bar code symbol or a text character, is likely in the field of view of the reader. Normally, analysis of image data includes the step of detecting for edge transitions in the image information. If the control unit determines that the image data includes more than a predetermined number of edge transitions, then the control unit imparts appropriate control over various reader elements to change the mode of operation of the reader. Normally, the control unit changes the mode of operation of the reader from a first mode, wherein the reader does not operate to decode or recognize image data to a second mode, wherein the reader operates to decode and/or recognize image data.

    摘要: The invention is an optical reader having a 2D image sensor that is configured to operate in a partial frame capture 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, attempts to decode for a decodable 1D symbol which may be represented in the image data, and captures a full frame of image data if the image data reading reveals a 2D symbol is likely to be present in a full field of view of the 2D image sensor.
