摘要:
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.

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.

When there is a copy inhibiting dot pattern in an image, an image destruction processing unit performs image destruction processing to image data, and a storage processing unit stores in a storage unit the image data after the image destruction processing. An RGB/CMY conversion processing unit converts the image data into CMY image data C1, M1, Y1, and a UCR/black creation processing unit sets coefficient α of Formula “K1=min (C1, M1, Y1)×α” to “1,” and creates image data K1, C2, M2, Y2 by using Formula “C2=C1−K1, M2=M1−K1, Y2=Y1−K1.”

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. If it is determined that the password extracted by the extraction unit and the password created by the password creating unit correspond to each other, the prohibition on the output will be lifted.

An image reading apparatus includes: an image reading unit for reading an original image at a first resolution and converting the read original image into first image data; a data analysis unit for analyzing the first image data; a resolution determination unit for determining an appropriate second resolution on the basis of an analysis result of the data analysis unit; and a resolution conversion unit for converting the first image data into second image data relating to the second resolution and outputting the second image data.

While a ferrule held by a clamping apparatus is rotated by a predetermined angle, respective interference fringe images of a spherical leading end part of the ferrule are obtained at three or more rotational positions. Respective interference fringe center positions are obtained in thus obtained three or more interference fringe images. The center position of a circle passing near each of the interference fringe center positions is calculated and defined as a measured center position. Relative distance information between the measured center position and a position corresponding to the rotational center position of the spherical leading end part of the ferrule or the relative distance information and relative directional information thereof are outputted as an inclination error adjustment value for the axis of the ferrule.
