    • An image of an inspection target having a concave and convex pattern is picked up in an off-focus state by an image pickup element 4. Further, the image of the inspection target picked up in the off-focus state is taken in by an image processing computer 6. Based on the image, the image processing computer 6 prepares a light intensity profile having a peak corresponding to a boundary portion between a concave portion and a convex portion of the concave and convex pattern of the inspection target. For example, a change of the width of the concave or convex portion of the concave and convex portion can be detected very accurately, by measuring the width of the concave or convex portion of the concave and convex portion on the basis of the intensity profile.
    • 通过图像拾取元件4在离焦状态下拾取具有凹凸图案的检查对象的图像。此外,以离焦状态拍摄的检查对象的图像被摄像 基于图像,图像处理计算机6准备具有对应于检查对象的凹凸图案的凹部和凸部之间的边界部分的峰值的光强度分布。 例如,通过基于强度分布测量凹凸部的凹部或凸部的宽度,可以非常精确地检测凹凸部的凹部或凸部的宽度的变化。

    • A rental service handling electronic data is faced with a challenge of accurately managing time within a machine. With currently available systems, time instant data to be set could be tampered using a machine and it is therefore difficult to protect the rights over programs and data. Disposed within a memory card are a time measuring part which is capable of measuring time, a memory part in which key information and various types of data are coded and stored, a power source part which supplies power to the time measuring part and other respective parts, a code processing part which decodes time instant information set in the time measuring part and codes time instant information retrieved from the time measuring part using the key information, and a calculation control part which controls so as to validate or invalidate rights based on the various types of time instant information, whereby management of time such as the term of validity of data is always performed inside the memory card.
    • 处理电子数据的租赁服务面临着准确管理机器内部时间的挑战。 使用当前可用的系统,可以使用机器篡改要设置的即时即时数据,因此难以保护对程序和数据的权限。 在存储卡内设置有能够测量时间的时间测量部分,其中密钥信息和各种类型的数据被编码和存储的存储器部分,向时间测量部分和其他各个部分供电的电源部分 代码处理部,其对所述时间测量部中设定的时刻信息进行解码,并且使用所述密钥信息对从所述时间测量部检索到的时刻信息进行编码;以及计算控制部,其基于各种方式来控制以使所述权限有效或无效 时间瞬间信息的类型,从而总是在存储卡内部执行诸如数据有效期的时间的管理。
