An information processing apparatus able to normally unmount a memory and disconnect communication with a first external apparatus when receiving a processing request from a second external apparatus in a state that the first external apparatus mounts the memory connected to the apparatus. A multi-function peripheral as the processing apparatus () includes a controller OS. When receiving a processing request from a second host PC (B) as the second external apparatus in a state where the multi-function peripheral is in communication with a first host PC (A) as the first external apparatus (S), the controller OS requests the first host PC to unmount the memory (S), if the memory is mounted thereon. When receiving an unmount instruction from the first host PC (S), the controller OS unmounts the memory, disconnects the connection with the first host PC (S), and starts communication with the second host PC (S).

Information processing apparatus, control method thereof, and storage medium

An image processing apparatus has a plurality of functions and is adapted to make one or more functions operable by activating programs corresponding to functions. The image processing apparatus includes a selection unit adapted to select a function to be enabled in advance to the other functions when power of the image processing apparatus is turned on or when operation of the image processing apparatus is resumed from a low-power standby state, and a control unit adapted to perform control such that a program corresponding to the function selected by the selection unit is made executable in advance to the other programs.

Image processing apparatus and method of starting image processing apparatus

An unmount state storing unit configured to store a state of unmount processing to end access processing to a memory card attached to a device from a host computer is provided. During a period from immediately after a host computer executes the unmount processing until detaching of the memory card is detected, a value of the host computer unmount state storing unit is stored as 'true'. During the period in which this value is 'true', a host computer mount request from another host computer is denied. Consequently, after the access processing to the memory card attached to a device by the host computer has ended, contents of the memory card cannot be read from the other host computer while the memory card is still attached.

Device, control method thereof, and program

A data processing apparatus has an interpreter environment for dynamically implementing a program constructed based on a command set defined independently of a native command group, in a native environment constructed based on the native command group processed by a processor configuring hardware. The apparatus generates an intermediate data stream in each of a plurality of stages into which an input data stream is divided in interpretation in the native environment and filters the intermediate data stream to generate a filtered data stream in the interpreter environment.

Image processing apparatus and control method thereof

A processing apparatus which is capable of preventing an priority reservation for a particular period from being set for all of a plurality of apparatuses and improving convenience for a general user who does not use an priority reservation service, in a system for which the priority reservation is available. Reservation information about a reservation for priority use of peripherals (MFP-A, B, and C) is stored. The number of peripherals that are not reserved for priority use during a particular period in the peripherals with reference to the reservation information is detected. When the number of peripherals is one, an instruction not to accept a reservation for priority use during the particular period to the single peripheral that are not reserved for priority use during the particular period in the peripheral is issued.

Processing apparatus, method of processing priority reservation therefor, and storage medium for storing program

A program that is to be preferentially loaded into a memory is stored in a specific memory and the program stored in the specific memory is changeable to another program. Thus, the program that is to be preferentially loaded into the memory is thereby made changeable.

Multifunction processing apparatus and control method thereof

A data processing apparatus and method configured to load a program corresponding to each of a plurality of functions into a memory, the apparatus and method including storing a program for a specific function from among the plurality of functions, storing a program for a function different from the specific function from among the plurality of functions, loading the program for the specific function into the memory, and loading the program for the function different from the specific function into the memory after power is supplied to the second storage unit based on a request for accessing the second storage unit generated during execution of the program for the specific function.

Data processing apparatus configured to load a program corresponding to each of a plurality of functions into a memory and execute the loaded program, and method for loading programs in the data processing apparatus

An image processing apparatus includes a number of processing modules which apply a process to predetermined data in inputted print data; a detecting unit configured to detect a processing module that has performed a process during processing by the plurality of processing modules of print data inputted in a predetermined mode; and a setting unit configured to make a setting that enables a processing module detected by the detecting unit, after the end of the predetermined mode.

Image processing apparatus and control method thereof, processing module drive control method, and data processing apparatus

A color image monitoring apparatus is capable of controlling the color correction characteristics by external commands. A color correction information memory stores input masking coefficients and .gamma. correction tables. The input masking coefficients can be loaded in the memory by an external command. In the .gamma. correction tables includes a table for the correction values for the .gamma. values at pitches of 0.1 within a range of 1.0 to .alpha. (&gt;1.0). When a .gamma. correction process is executed, the tables to be used are selected by specifying the .gamma. values by the external command. A color correction circuit performs the respective .gamma. correction and input masking processes using the .gamma. correction tables and input masking coefficients stored in the memory.

Image monitoring apparatus having a common interface for commands and

There is disclosed a print system in which one of printers connected to a network is selected in accordance with the attributes of print data without requiring a user to operate a host computer, wherein a printer, which received print data from the host computer via a network cable, checks if the received print data can be printed, and if it is determined that the print data can be printed, the print data is printed; if it is determined that the print data cannot be printed, the print data is transferred to another printer, which can print the print data, via the network cable.

Image forming apparatus, image forming system, and image forming method

A color image processing apparatus includes a storage device for storing a plurality of color processing parameters which correspond to a plurality of monitor types, respectively, a receiver for receiving a command indicating a monitor type, a selector for selecting a color processing parameter from the storage device which corresponds to the monitor type indicated by the command received by the receiver and a color processor for color processing image data defining an image whose display is dependent on a display characteristic of the monitor on the basis of the color processing parameter selected by the selection.

Color image processing apparatus for processing image data based on a

A color image processing apparatus is provided with a color correction information memory to store input masking coefficients and .gamma. correction tables. The input masking coefficients can be loaded on the memory by external commands. The .gamma. correction tables include a table for correction values for the .gamma. values at pitches of 0.1 within a range of 1.0 to .alpha. (&gt;1.0). When a .gamma. correction process is executed, the table to be used is selected by specifying the .gamma. value by an external command. With a color correction circuit, the .gamma. correction process and input masking process are executed using the .gamma. correction tables and input masking coefficients stored in the memory.
