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 aiming pattern is used with an automatic focusing system for an imaging-based bar code reader. The combination of the thick horizontal line and the thin vertical line yields an aiming pattern that can be effectively used for ranging purposes while at the same time providing sufficient illumination for decoding 1-D barcodes.

Abstract: An image scanning device is provided which includes a system for determining the distance to a target to be scanned. The image scanning device includes an optical system and an image sensor array for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.

Abstract: An optical code reading system having an auto-exposure system for use with a variable resolution imaging sensor in which very low resolution images are used to determine exposure parameters is presented. The very low resolution images can be transferred much faster than high resolution images which results in a very fast auto-exposure system. The optical code reading system further includes an optical zoom system for zooming in and out of a target without the use of any moveable components. The optical zoom system makes use of a binning and/or subsampling feature of the imaging sensor for zooming in and out of the target. High-speed decoding methodologies are also presented for the optical code reading system. One decoding methodology utilizes low resolution images for performing high-speed decoding. Other methodologies utilize low resolution images and higher resolution images, if the optical code imaged by the low resolution images is not decoded successfully.

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. In this manner imager settings can be quickly determined by transferring and examining only the segment of the sensor array data.

Abstract: A programmable imaging pixel array and barcode imager incorporating the same are provided where the aspect ratio of each pixel of the imaging pixel array can be changed to better match the type of barcode being imaged. For lower density barcodes that are far away from the barcode imager, for example, the aspect ratio of the imaging pixel array can be programmed on the fly to maximize aspect ratio and thereby increase the signal-to-noise ratio in the received signal. When reading high density barcodes, such as PDF417 barcode symbols, the aspect ratio of the imaging pixel array can also be programmed on the fly to obtain an aspect ratio which does not compromise the performance of the barcode imager.

Abstract translation: 提供了一种可编程成像像素阵列和结合其的条形码成像器，其中可以改变成像像素阵列的每个像素的纵横比以更好地匹配正在成像的条形码的类型。 对于远离条形码成像器的较低密度条形码，例如，成像像素阵列的纵横比可以在飞行中编程以最大化纵横比，从而增加接收信号中的信噪比。 当读取诸如PDF417条形码符号的高密度条形码时，成像像素阵列的纵横比也可以在飞行中编程以获得不影响条形码成像器的性能的纵横比。
