    • An image forming apparatus includes a determining section for determining if a value indicative of a size of the background portion in the background pattern is smaller than a predetermined threshold value; and a background pattern correcting section which corrects the background portion and the latent image portion, when the determining section determines that the value is smaller than the threshold value, so that the value indicative of the size of the background portion becomes equal to or larger than the threshold value, and which forms a background pattern having a corrected background portion in which a copy prohibiting pattern is embedded, wherein the image forming section forms on a sheet the background pattern when the determining section determines that the value is smaller than the threshold value, and forms on the sheet the background pattern when the value is equal to or larger than the threshold value.

    • An apparatus prohibits an unfair copying of a document by forming a latent image region and a background region on the document in a manner that prevents detection of their existence. The apparatus has a controller that detects background region densities and latent image region densities. The controller extracts only a background region density, which enables a special dot pattern to be detected when copying the image of the document. The controller also extracts only a latent image region density, at which a dot image corresponding to the dots constituting the latent image region is not formed on a copy when copying the image of the document. The controller then derives the background region densities and the latent image region density matching with the background region density.
    • 设备通过以防止其存在的检测的方式在文档上形成潜像区域和背景区域来禁止文档的不公平复制。 该装置具有检测背景区域密度和潜像区域密度的控制器。 控制器仅提取背景区域密度,这使得在复印文档的图像时能够检测到特殊的点图案。 控制器还仅提取潜像图像区域密度,当复印文档的图像时,在副本上没有形成与构成潜像区域的点相对应的点图像。 然后,控制器导出背景区域密度和与背景区域密度匹配的潜像区域密度。

    • An image processing device 100 has a reading unit 2, a density measuring unit 81, and an extraction unit 82. The reading unit reads a plurality of samples 9. The density measuring unit 81 measures the density of the background image of the plurality of samples 9 having been read by the reading unit 2 and the density of the latent images included in the plurality of samples 9. The extraction unit 82 extracts combinations of background image and latent image. The background image has a density being equal to or less than a first predetermined value. The latent image has a density difference from the background images having a density equal to or less than the first predetermined value. The latent image has a density being equal to or less than a second predetermined value.
    • 图像处理装置100具有读取单元2,浓度测量单元81和提取单元82。 读取单元读取多个样本9。 浓度测量单元81测量由读取单元2读取的多个样本9的背景图像的浓度和包含在多个样本9中的潜像的浓度。 提取单元82提取背景图像和潜像的组合。 背景图像的密度等于或小于第一预定值。 潜像与密度等于或小于第一预定值的背景图像的浓度差异。 潜像的密度等于或小于第二预定值。
