An image processing system and method for copying an original document while maintaining the security of the document and for providing a high quality copy each time a copy is required. The system and method include inputting image information, generating output limitation information corresponding to the inputted image information, storing the inputted image information and the corresponding output limitation information, reading a document containing specifying information for specifying the stored image information, outputting the stored specified image information in accordance with reading of the specifying information, determining whether the image information specified by reading the specifying information is to be output based on the output limitation information corresponding to the image information, controlling the outputting of the image information in accordance with the determination, and varying the output limitation information corresponding to the image information in accordance with outputting of the image information.

An image processor includes spatial filters which execute parallel processing in units of component data of image data made up of a plurality of component data, and an original image color determination unit selects if input image data from a color image input unit is to be processed as a monochrome or color image. When it is selected that the input image data is to be processed as a monochrome image, the processing operations of the spatial filters for the image data are controlled to be executed stepwise.

An image processing device and method for convert multi-value image data having light and dark information per pixel into binary data for pseudo half-tone representation. A binarization results delay unit holds binarized data near the pixel of interest obtained by a binarizing unit, a slice value control unit calculates the amount of change in the slice value based on the concentration of the image or the binarized data pattern thereof, and determines the binarized slice value S based on the amount of change in slice value. The binarizing unit binarizing input image signals using the binarized slice value S. Thus, control of the amount of dot concentration in an arbitrary concentration area, and accurate control of texture can be realized.

Upon gradation converting input m-bit image information into n-bit image information (m and n are integers; m>n), random numbers, the maximum values of which are changed in accordance with the input values of the m-bit image information, are generated at periods of two or more pixels, and the random numbers are selectively output while switching their signs to positive/negative within the period of two or more pixels. The output signal values and the input values of the m-bit image information are added to each other, and the sum signal values are converted into n-values by a density preservation type quantization method. With this control, the problems of sweeping, texture, and the like of the conventional density preservation type quantization method can be solved without emphasizing the granularity of an image.

There is provided a service providing system that is capable of preventing personal information on a user who has used a service from being leaked to other users without spoiling the convenience for the user, and increasing the frequency with which the user uses the service. The service providing system includes a service providing apparatus that provides a service for the user, and a password issuing device that issues a password with an expiration date that is made to correspond to identification information held by the user in response to the payment of a fee by the user. The service providing apparatus includes a memory that stores setting data used for simplifying operations relating to the service provided for the user, and a CPU. The CPU authenticates the user according to the identification information on the user, the password issued to the user, and the expiration date thereof, and gives the authenticated user a permission to perform operations on the setting data stored in the memory.

The present invention is intended to solve a problem which may be encountered during a transfer from a mode for searching a desired still image to a mode for performing actual reproduction during the process in which still image information is reproduced from a tape-shaped recording medium on which a multiplicity of helical tracks are formed for one picture of still image information, one picture of still image information and address information indicative of the number thereof being recorded in the multiplicity of helical tracks. The sensation of an operator can be made coincident with an actually reproduced still image, for example, by effecting such mode transfer by detecting and using a number adjacent to a desired still image number or by shifting the tape-shaped recording medium by a predetermined amount. Accordingly, it is possible to to search a desired still image rapidly and easily.
