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.

This invention provides an image processing system and image processing method which can promote efficient use of a memory by vectorizing all data of a representative object and, for the same or similar object, referring to the vectorized representative object and using difference data and also convert the same or similar objects at once by editing only the representative object. Input image information is vectorized. The vector data of a representative object is stored. Identity between a target object and the representative object is determined. If the two objects are identical, property information containing information about the reference destination of the vector data of the representative object is stored in place of the vector data of the target object.

Vector data corresponding to a scanned original image is generated. An edit image of the original image corresponding to the display resolution of a display is generated on the basis of the vector data, and display of the edit image on the display is controlled.

An electronic file corresponding to a scanned original image is specified on the basis of the original image. If the electronic file corresponding to the original image cannot be specified, the original image is converted into vector data. The vector data is converted into image data. The first image data of the original image is compared with the second image data generated by the second conversion unit. On the basis of the comparison result, the first image data or vector data is selected as the electronic file corresponding to the original image.

A read document image is converted into first vector data. First layout structure information representing the layout structure of the first vector data is generated. The first layout structure information is changed into second layout structure information on the basis of preset layout setting information. The first vector data is converted into second vector data on the basis of the changed second layout structure information.

This invention provides an image processing system and image processing method which can specify and save an input image which matches a predetermined pattern and also simplify the determination process. Vector data is generated from image information input by a scanner. Keyword information to inhibit reuse, which is contained in the image information, is input. The similarity between the input vector data and the keyword information is determined. Only when it is determined that the vector data is similar to the keyword information, the generated vector data is stored in a storage device.

In the case in which an image processing mode is a high-speed copy mode in which follow-up control is possible, setting is made to perform “follow-up control” for setting a mode for not compressing an image or a fixed length compression mode for an image read by a scanner, storing an inputted image in a memory in accordance with the setting, and outputting the image stored in the memory to a printer during scanning. Consequently, image input/output processing from input and storage of an image in the memory until output of the stored image can be performed at high speed.

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.
