  • Publication number: 20110317231
    Abstract: An image processing apparatus includes a document conveying unit, an image reading unit, a gradient calculating unit, a gradient comparing unit and a document discriminating unit. The image reading unit scans a document conveyed by the document conveying unit in a scanning direction orthogonal to a conveying direction and detects pixel values of color components of each pixel. The gradient calculating unit calculates a gradient of the pixel value of each color component in the conveying direction for each pixel based on the detected pixel values. The gradient comparing unit compares differences of gradients among color components for each pixel and extracts the pixel where the graduent difference is below a threshold value. The document discriminating unit discriminates whether each pixel is color or black-and-white based on pixel values using discrimination criteria different for the specific pixels extracted by the gradient comparing unit and other pixels.

  • Patent number: 7831041
    Abstract: An image forming apparatus includes a reader for reading image data from a document. An inherent information storage stores information inherent to the image forming apparatus. An encryption key generator generates an encryption key based on the inherent information in the inherent information storage, and an encryptor encrypts the image data read by the reader based on the encryption key to generate encryption data. An acceptor accepts an image formation designation to form an image on a recording sheet. A decryption key generator generates a decryption key based on the inherent information in the inherent information storage if the image formation designation is accepted by the acceptor. A decryptor decrypts the encryption data based on the decryption key to acquire the image data, and an image forming section forms the image on the recording sheet based on the data acquired by the decryptor.

  • Publication number: 20100195128
    Abstract: An image formation controller judges whether or not a tint block has been detected by a tint block processor upon judging that an automatic color determination mode is set in a multi functional peripheral. The image formation controller causes an image forming section to perform a monochromatic image forming operation if the tint block is a chromatic tint block when the tint block was detected by the tint block processor. On the other hand, the image formation controller causes the image forming section to perform an image forming operation corresponding to a determination result by an ACS processor when no tint block was detected and when the tint block was determined to be a monochromatic tint block.

  • Publication number: 20100188675
    Abstract: An image forming apparatus has R, G and B dot pattern detection units that detect the presence/absence of image data of operation restricting dot patterns of R, G and B color components respectively in document image data. A dot pattern color determination unit determines the presence/absence of the operation restricting dot pattern and the color of the operation restricting dot pattern on a document from the detection results from the detection units. A restriction detail table storage unit stores, beforehand, a table showing the correspondence relationship between the color of the operation restricting dot pattern and a restriction detail concerning a copy operation. An image formation control unit determines, based on a determination of the dot pattern color determination unit and the table, whether a current setting of a multi-functional peripheral is relevant to the restriction detail corresponding to the color, and, when relevant, prohibits the copy operation.

  • Patent number: 7701598
    Abstract: In an image forming device, output is prohibited by an output control unit if specific image data is detected in image data obtained by reading an original document. The current data is acquired when the output control unit prohibits output, and the password is created in accordance with the current data. The image data which is prohibited from being output by the output control unit is transmitted to an administrator, and then if output permission is obtained by the administrator, output permitted data is generated as an image in which a password created by the password creating unit is embedded in such a manner that a user can not identify the password, and is output by the output unit. The output permitted image outputted by the output unit is read by the reading unit, and then the embedded password data is extracted by the extraction unit.

  • Publication number: 20090268256
    Abstract: A special pattern determination section determines whether a special pattern is included in a document image read by a document reading section. If the special pattern determination section determines that the special pattern is included, the breaking pattern applying section applies a breaking pattern to the document image, and the print image generating section accumulates image data of the document image applied with the breaking pattern into a memory. On the other hand, if it is determined that the special pattern is not included, the print image generating section accumulates the image data of the document image directly into the memory. Then, if it is set by a user so as not to print the breaking pattern, the controller deletes image data of the document image accumulated in the memory and applied with the breaking pattern.
