摘要： A quasi one-dimensional focal plane array for vision scanners which records a portion of an image of a bar code label which is substantially less than the entire image of the bar code label. The focal plane array has more than 1000 columns of pixels and less than 100 rows of pixels for producing the image of the portion of a bar code label. Additional portions are scanned by the focal plane array as the portions move across the focal plane array. A vision scanner employing the quasi-one-dimensional focal plane array requires only enough memory to store the image of the portion of the bar code label. Each image is recorded, stored, and decoded in turn. The image of the bar code label may be demagnified. A system employing such a vision scanner is located at a distance high enough from an article conveyor to provide a substantially uniform depth of field, despite variations in the height of the articles.
摘要翻译：一种用于视觉扫描仪的准一维焦平面阵列，其记录条形码标签的图像的一部分，其大致小于条形码标签的整个图像。焦平面阵列具有超过1000列的像素和少于100行像素，用于产生条形码标签部分的图像。当部分移动通过焦平面阵列时，附加部分被焦平面阵列扫描。使用准一维焦平面阵列的视觉扫描仪仅需要足够的存储器来存储条形码标签的该部分的图像。每个图像依次被记录，存储和解码。条形码标签的图像可以被缩小。尽管物品的高度有变化，但是使用这种视觉扫描器的系统位于与物品输送机足够高的距离处，以提供基本均匀的景深。

摘要： A bar image enhancement system and method for vision scanners which divides an image of an article having a bar code label into groups of pixels, with each pixel having an intensity value, and which minimizes processing time by employing simple algebra. The system includes a camera for generating an analog signal representing the image. Processing circuitry converts the analog signal into a digital signal. A controller divides the image into groups, determines a contrast value for predetermined groups by subtracting the minimum intensity value from the maximum intensity of each group.

摘要： An imaging reader has a two-dimensional array of image sensors for capturing return light from a two-dimensional symbol over a field of view as pixel data to be stored in internal random access memory (RAM) of a controller even though the internal RAM has less storage bytes than the number of sensors. The controller determines a size and a location of the symbol in the field of view, maps and subdivides the symbol into a plurality of image capture zones based on the symbol size and location, sequentially captures the return light from each zone, sequentially stores the pixel data from each zone into the internal RAM, sequentially digitizes the stored pixel data from each zone as digitized data, and decodes the digitized data from all the zones.

摘要： The disclosed bar code reader includes an auto-focusing component for rapidly producing in focus images. An imaging system makes use of an aiming pattern that impinges upon the coded indicia of a target. The imaging system includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The imaging system also includes a movable mirror mounted for movement along a path of travel to reflect light passing through the focusing lens onto the pixel array. A drive motor moves the mirror relative the lens to adjust a focus of an image of the object formed at the pixel array. An automatic focusing component of the imaging system analyzes the aiming pattern reflected from the target object and projected onto the pixel array by the lens. The automatic focusing component issues commands to the drive motor causing the mirror to move along its path of travel to a suitable position for properly focusing the target object onto the pixel array.
