摘要: The present invention is directed to a method for reading a bar code symbol with an optical reader. The method includes the step of scanning the bar code symbol to obtain a plurality of scan lines. Each of the plurality of scan lines includes a linear array of N-pixel values. Adjacent pixels in the linear array of N-pixel values are separated by a sample separation distance. A reconstructed scan line is generated that interleaves the N-pixel values from selected scan lines of the plurality of scan lines. A reconstructed pixel sample separation distance of adjacent interleaved pixels is an integer fraction of the pixel sample separation distance.

摘要: A digital image reading system including an image sensor and a computer that is programmed to adjust the frame rate of the image sensor, and to obtain a maximum frame rate of the image sensor for obtaining an acceptable image. An algorithm for adjusting the frame rate evaluates image parameters and calculates new exposure times, gain values, and exposure settings to support a maximum frame rate of the image sensor. A process for obtaining an acceptable image with an image reader evaluates an image signal level and adjusts the frame rate if the signal level is outside of a predetermined range. The process adjusts the image sensor to run at a maximum operational frame rate. A digital image reading system including multiple separate digitizers for use in various read environments and under various read conditions.

摘要: A method of operating an image reader includes the steps of: searching a digital image for nominally straight edges; characterizing the nominally straight edges in terms of length and/or direction; determining a predominant orientation of the nominally straight edges; establishing a group of edges as a function of their proximity to the center of the image; establishing a group of edges as a function of their proximity to other remaining edge positions; and, transmuting a rectangle bounding those edges into a rectified image; wherein a rectified image is an image that is cropped or rotated.
