摘要： An image input section enters a document image including a bar code, and converts the document image into a binary image. A small pattern removing section removes small patterns from a binary image sent from the input section. A labeling section separates the binary image into labeled regions and calculates the feature quantity including a center position of each labeled region. A region detecting section makes a group of labeled regions spaced at a predetermined positional relationship based on their feature quantities and detects a bar code candidate region. A decoding section decodes the bar code based on the feature quantity involved in the bar code candidate region.

摘要： An apparatus for receiving input data values representing an array of picture elements of a source image containing one or more bar code regions, whereby the input data values are converted to bi-level values representing black or white states which are stored in an image memory, while in addition the bi-level values are processed to obtain data representing an image in which a "skeleton" central portion of the bar code region appears as an all-black region, while background black regions are eliminated. A central position and the slope of a central axis of the bar code region are computed based on that "skeleton" region, and data values in the image memory which conform to the central axis are then read out, to read the bar code data.

摘要： An image input section enters a document image including a bar code, and converts the document image into a binary image. An image memory section memorizes the binary image supplied from the image input section. A mask judging section performs a scanning operation using an M.times.M pixel window for detecting an alternate pattern from the binary image supplied from the image input section. A small pattern removing section removes small patterns from a binary image sent from the mask judging section. An expanding section expands a pattern involved in a binary image by an amount equivalent to k1 pixels when this binary image is sent from the small pattern removing section. A contracting section contracts a pattern involved in a binary image by an amount equivalent to k2 pixels when this binary image is sent from the expanding section. A region detecting section obtains the feature quantity of each pattern involved in a binary image sent from the contracting section, and detects a bar code candidate region based on the detected feature quantity. And, a decoding section decodes a detected bar code by reading a specific image region from the image memory section when the specific image region corresponds to the bar code candidate region detected by the region detecting section.
摘要翻译：图像输入部分输入包括条形码的文档图像，并将文档图像转换为二进制图像。图像存储部存储从图像输入部提供的二值图像。掩模判定部分使用从图像输入部分提供的二进制图像中检测替代图案的MxM像素窗口进行扫描操作。小图案去除部分从掩模判断部分发送的二进制图像中去除小图案。当从小图案去除部分发送二进制图像时，扩展部分将涉及二进制图像的图案扩展相当于k1个像素的量。当从扩展部分发送二进制图像时，收缩部分将涉及二进制图像的模式收合相当于k2个像素的量。区域检测部分获得从收缩部分发送的二进制图像中涉及的每个模式的特征量，并且基于检测到的特征量检测条形码候选区域。并且，当特定图像区域对应于由区域检测部分检测到的条形码候选区域时，解码部分通过从图像存储部分读取特定图像区域来解码检测到的条形码。
