    • To obtain image outputs which are equivalent to those obtained with local outputs even with regard to images received from an external device, there is provided an image input/output apparatus having an input section for inputting image data of original images, and an output section for outputting image data, and being connected to at least one other image input/output apparatus via a communication medium. A transmission section transmits the image data input by the input section and image accompanying information relating to the input image data to the other image input/output apparatus. A receiving receives image data and image accompanying information relating thereto from the other image input/output apparatus. An output control section carries out control so as to output images using the output section based on the image data and the image accompanying information received by the receiving section.

    • A density signal value determination method, an image forming apparatus, and an image processing system are configured to automatically and optimally determine the density of a copy-forgery-inhibited pattern image that includes a latent image and a background image. In a density signal value determination method, a test sheet, on which a plurality of latent image patches and a plurality of background image patches are formed, is outputted. Subsequently, the luminance, the density, and the reflection density of each of the patches are obtained from image data obtained by reading this test sheet. Then, an optimal combination of a latent image patch and a background image patch is selected according to the obtained values. Finally, density signal values used to generate the selected patches are set to generate a latent image and a background image.

    • A scanner with an automatic density adjustment function executes image processing in which prescanning is performed and the background level is made white before the next scan starts. However, if an automatic density adjustment is applied when the same document is read as a color image and as a monochrome image, it is necessary to perform prescanning before the color image is read and prescanning before the monochrome image is read. Reading the image therefore takes time. Accordingly, if an automatic density adjustment based upon prescanning has been designated, prescanning is carried out and then a histogram is obtained for each of the components R, G and B and the background levels are calculated for color scanning and monochrome scanning. A table in a scanner image processor is set in accordance with a background peak value PeakBW for monochrome scanning. For color scanning, on the other hand, the table in the scanner image processor is set in accordance with a background peak value PeakCL for the color scan.
    • 具有自动浓度调节功能的扫描仪执行图像处理,其中执行预扫描并且在下一次扫描开始之前使背景级别变为白色。 然而,如果在将相同的文档作为彩色图像和单色图像读取时应用自动浓度调整,则需要在读取单色图像之前读取彩色图像和预扫描之前执行预扫描。 因此,阅读图像需要时间。 因此,如果已经指定了基于预扫描的自动浓度调整,则进行预扫描,然后对于分量R,G和B中的每一个获得直方图,并且为彩色扫描和单色扫描计算背景水平。 根据用于单色扫描的背景峰值PeakBW来设置扫描仪图像处理器中的表格。 另一方面,对于彩色扫描,扫描仪图像处理器中的表根据用于彩色扫描的背景峰值PeakCL来设置。
