Abstract: 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 (20) includes a controller OS. When receiving a processing request from a second host PC (10B) as the second external apparatus in a state where the multi-function peripheral is in communication with a first host PC (10A) as the first external apparatus (S3100), the controller OS requests the first host PC to unmount the memory (S3201), if the memory is mounted thereon. When receiving an unmount instruction from the first host PC (S3004), the controller OS unmounts the memory, disconnects the connection with the first host PC (S3005), and starts communication with the second host PC (S3101).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An image forming apparatus to communicate through a USB interface with an information processing apparatus and an operation unit. The image forming apparatus includes a change unit, a first determination unit, and a second determination unit. The change unit changes a connection state between a state in which the image forming apparatus as a USB host is connected to the operation unit as a USB device and a state in which the information processing apparatus as a USB host is connected to the operation unit as a USB device. When it is possible to communicate with the information processing unit through the USB interface and the information processing apparatus can control the operation unit, the change unit changes a connection state from a connection between the image forming apparatus (host) and the operation unit (device) to a connection between the information processing apparatus (host) and the operation unit (device).

Abstract: 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. (>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.
