A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function.

Input raster image data is divided into objects of each attribute. The division results, and charge information representing a consideration accrued from a vectorized process for the division results are displayed. It is designated whether to execute the vectorized process for the displayed division results. The vectorized process of converting the raster image data into vector data is executed on the basis of the contents of the designation.

Image processing apparatus, control method therefor, and program

An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network.

Information processing apparatus connected to a printing apparatus via a network and computer-readable storage medium having stored thereon a program for causing a computer to execute generating print data in the information processing apparatus connected to the printing apparatus via the network

In a computer system including a job scheduler which divides an input job and determines a client apparatus to assign the divided job, and a task manager which transmits the divided job to the client apparatus determined by the job scheduler, the job scheduler assigns the same job to a plurality of client apparatuses when the number of client apparatuses is larger than the number of divided jobs, and when the job is finished in one of the plurality of client apparatuses assigned the same job, execution of the job in the remaining client apparatuses is canceled so that the time until all jobs are finished is shortened.

Divided job scheduler

This invention provides an image processing system and image processing method which allow a user to easily confirm conversion result information when image information is converted into vector data. Image information input from an input device () is vectorized by a data processing device (). Vector data which has successfully been vectorized is converted into image data. The input image information and the converted image data are combined to generate and output combined image data.

Image processing system and image processing method

Even when a CPU gains higher performance and a distributed computing environment is being put in place, it is not easy to follow the speed of hardware image processing implemented by dedicated hardware. Hence, jobs of filter processing having a heavy operation load and low distributability are selectively and intensively input to a small number of resources having performance as high as possible. On the other hand, since the color conversion processing and gamma processing have high distributability, even when jobs are input to many resources having low performance, an improvement of the processing speed can be expected. Therefor, color conversion processing and gamma processing distribute jobs to many resources.

Information processing apparatus and its control method

In a network print system in which a printer and at least one client are connected to each other through a network, and at least a part of a job for the printer can be subjected to load distributed processing by grid computing, wherein when a printer driver of the printer is installed on any one of the at least one client, the system is adapted to build a grid computing network. In this arrangement, it is easily to build the grid computing network in which the printer job is subjected to load distributed processing.

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 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.

An image processing apparatus includes: a reading unit adapted to read an image and to generate image data representing the image; a separating unit adapted to separate the image data obtained by the reading unit into a plurality of objects corresponding to attributes; a selecting unit adapted to select a predetermined attribute of the image; a vectorization unit adapted to perform a vector conversion process for the image data separated by the separating unit in accordance with the predetermined attribute selected by the selecting unit; and an output unit adapted to output the image data processed by the vectorization unit.
