摘要:
The present invention has a transmission side apparatus to which an image to be transmitted is inputted, and an outline vector along the edge of the inputted image is extracted. The transmission side apparatus transmits data of the extracted outline vector to a receiving side apparatus via a data line. The receiving side apparatus reproduces the image in accordance with received outline vector data so as to output it to a predetermined visible image generating apparatus.

Disclosed are an image processing method and apparatus for applying spatial filtering processing to n-bit multilevel image data, converting the processing image data to two-level or multilevel image data and converting the resulting image data to data capable of being expressed using high-resolution dots. The filtered image data is subjected to a luminance-to-density conversion and is further converted to two or four levels by a four-level/two-level conversion circuit which makes common use of circuitry for executing both two-level error diffusion processing and four-level error diffusion processing. The four-level/two-level conversion circuit clamps the error produced in four-level conversion processing to the number of significant bits of the error produced at execution of the two-level conversion processing. As a result, a common circuit can be used for both the two-level conversion processing and the four-level conversion processing.

摘要:
An image processing apparatus for providing at least a service to a service requester receives a service execution request and authentication information of a service requester from the service requester and issues a request for authenticating the service requester to an authentication service. Also, the image processing apparatus executes the requested service based on an authentication result transmitted from the authentication service. Further, the image processing apparatus manages an execution state of the executed service and an authentication state of the service requestor by associating the execution state with the authentication state.

An information updating apparatus compares resolution information and color information acquired from received image data with resolution information and color information acquired from an external apparatus, and, if an amount of information of the resolution information and color information acquired from the received image data is larger than an amount of information of the resolution information and color information acquired from the external apparatus, replaces image feature amount data stored in the external apparatus with image feature amount data acquired from the received image data and replaces text data stored in the external apparatus with text data extracted from the received image data.

An encrypted communication system according to the present invention comprises an authentication server in which a user password and an encryption key of a server were registered, a client involved in utilization by a user, and a server providing a service. According to the encrypted communication system, shared credentials for the client and the server to conduct encrypted communication are generated separately by the authentication server and the client based on mutually shared information, a ticket is generated in which the credentials that were generated by the authentication server are encrypted with the encryption key by the authentication server, and the client encrypts information to be sent using the credentials generated by the client and attaches the ticket that was acquired from the authentication server to the encrypted information to send the encrypted information and the ticket to the server.

摘要:
An edge vector extraction unit (122) extracts edge vectors from an input image, and a variable-magnification processing unit (123) performs smoothing/variable-magnification processing of the edge vectors. A vertex point adjustment unit (100) selects each of vertex points constituting an edge vector loop as a vertex point of interest, discriminates the directions of two vertex vectors, which sandwich the edge point of interest, and adjusts the coordinate position of the vertex point of interest sandwiched between the two edge vectors having a predetermined combination on the basis of the combination of the directions, thereby suppressing a deformation of an output image, which may be caused by the variable-magnification processing.
摘要:
The contour vectors of an image are stored in a small storage capacity, and are enlarged/reduced in correspondence with a desired variable-magnification factor to be faithful to an input image. For this purpose, when a binary image is input from a binary image input unit (11), a contour vector extraction unit extracts contour vectors, and detects the positions of isolated points. The contour vectors are enlarged/reduced by a vector variable-magnification/smoothing unit (13), and a binary image is reproduced by a binary image reproduction unit (15). On the other hand, each of the isolated points is subjected to variable-magnification processing by an isolated point variable-magnification processing unit (14), so that its position is converted into a position corresponding to the variable-magnification factor, and points corresponding in number to the variable-magnification factor form the isolated point. Thus, the storage capacity of the isolated points can be reduced, and the isolated points are subjected to variable-magnification processing at an appropriate variable-magnification factor corresponding to the desired variable-magnification factor.
摘要:
When an image processing apparatus is newly installed, an access control request is issued from the image processing apparatus to a control apparatus at step S302. Then at step S303, regarding the image processing apparatus that has issued the access control request, an access control table to control access to functions of the image processing apparatus is automatically generated and registered in the control apparatus. In the control apparatus, access control is managed for each function of the image processing apparatus based on the registered access control table.
