    • An image information processor for producing a high-quality output image by emphasizing the contour portions of a character, a photograph and others and by preventing the generation of a Moire patterns in a dot region, for preventing an increase in the amount of codes, and for making it unnecessary to set desired binarization processing for each original, is provided. The processor includes a unit for scanning the original to convert each pixel data into an electric signal, a unit for controlling the start of image processing, a filter for carrying out enhancement processing among a plurality of pixels arranged in oblique directions after smoothing processing has been carried out among a plurality of contiguous pixels arranged in scanning and traverse directions, and a unit for carrying out at least one of binarization and binarization capable of realizing pseudo tone expression. According to the above construction of the image information processor, a unit for preventing the generation of a Moire pattern in the dot region of an original and for carrying out contour enhancement for the character/photograph region of the original can be formed of simple hardware capable of performing a high-speed operation, a clear binary output is obtained, and an increase in transmission time is prevented.
    • 一种图像信息处理器,用于通过强调字符,照片等的轮廓部分并且通过防止在点区域中产生Moir + E,acu e + EE图案来防止增加而产生高质量的输出图像 提供代码量,并且不需要为每个原稿设置所需的二值化处理。 处理器包括用于扫描原稿以将每个像素数据转换为电信号的单元,用于控制图像处理开始的单元,用于在平滑处理之后在倾斜方向上布置的多个像素之间执行增强处理的滤波器 在扫描方向和横越方向排列的多个连续像素之间执行的单元,以及用于执行能够实现伪色调表达的二值化和二值化中的至少一个的单元。 根据图像信息处理器的上述结构,用于防止在原件的点区域中产生Moir + E,acu e + EE图案并且用于对原稿的字符/照片区域进行轮廓增强的单元 可以由能够执行高速操作的简单硬件形成,可以获得清晰的二进制输出,并且防止传输时间的增加。

    • The present invention aims at providing a pattern matching device that conducts pattern matching on an image including a plurality of regions having different features with high precision, such as a pattern image including a plurality of layers.In order to achieve the above object, the present invention proposes a pattern matching device that executes pattern matching on a target image with the use of a template formed on the basis of design data or a picked-up image, which executes the pattern matching on a first target image with the use of a first template including a plurality of different patterns, creates a second target image with the exclusion of information on a region including a specific pattern from the first target image, and determines the degree of similarity between the second target image, and a second template including pattern information other than the specific pattern.
    • 本发明旨在提供一种图案匹配装置,其对包括具有高精度的不同特征的多个区域的图像(诸如包括多个图案的图案图像)进行图案匹配。 为了实现上述目的,本发明提出一种模式匹配装置,其使用基于设计数据形成的模板或执行模式匹配的拍摄图像来对目标图像执行模式匹配 使用包括多个不同图案的第一模板的第一目标图像从第一目标图像创建排除包括特定图案的区域的信息的第二目标图像,并且确定第二目标图像之间的相似度 目标图像,以及包括特定图案以外的图案信息的第二模板。
