    • An image data outputting apparatus and method form satisfactory images regardless of characteristics of an image forming apparatus by outputting copy forgery preventing image data for preventing copy-based forgery to the image forming apparatus. For example, a recording medium outputting system is constructed by connecting a LAN having a DB server managing transmission/reception of data to/from a database in the city office, and many LANs each having a terminal and a printer installed in a convenience store via a communication line and the Internet. Document data of a certificate is retrieved from the database in the city office by operating a terminal in a store, the retrieved document data is merged with copy forgery preventing image data corresponding to characteristics of a printer in the same store, and the merged data is outputted from the printer.
    • 无论图像形成装置的特性如何,图像数据输出装置和方法通过输出用于防止图像形成装置的防伪图像数据的防伪图像数据而形成令人满意的图像。 例如,记录介质输出系统是通过将具有管理数据的发送/接收数据的LAN与LAN中的数据库连接起来的LAN构成的,以及在便利店中安装有终端和打印机的许多LAN 通信线路和互联网。 通过在商店中操作终端,从城市办公室的数据库检索证书的文档数据,将检索到的文档数据与防止与同一商店中的打印机的特征对应的图像数据的防伪图像合并,并且合并的数据是 从打印机输出。

    • An image processing apparatus includes a segmenting unit, a representative-point setting unit, a vector calculating unit, and a screen-ruling-and-angle extracting unit. The segmenting unit segments an image into regions each having connected pixels. The representative-point setting unit sets a representative point representing each of the regions segmented by the segmenting unit. The vector calculating unit calculates vectors, each constituted of two representative points, on the basis of the representative points set by the representative-point setting unit. The screen-ruling-and-angle extracting unit extracts screen ruling and a screen angle used in the image on the basis of distribution of the vectors calculated by the vector calculating unit.
    • 一种图像处理装置,包括分割单元,代表点设定单元,向量计算单元,以及屏幕尺寸提取单元。 分割单元将图像分割成具有连接的像素的区域。 代表点设定单元设置表示由分割单元分割的每个区域的代表点。 向量计算单元基于由代表点设置单元设置的代表点来计算每个由两个代表点构成的向量。 屏幕排列角度提取单元基于由向量计算单元计算的矢量的分布来提取在图像中使用的屏幕角度和屏幕角度。
