An information processing apparatus which implements a rebuild process for restoring a mirroring state even when each of a plurality of connected external storage devices is configured to input and output data to and from a host controller by accessing a storage area of the host controller. When the host controller has issued an instruction to carry out the rebuild process in which data in one of the external storage devices is copied to the other one, one of the external storage devices which is about to write data to the storage area of the host controller for the rebuild process is caused to write the data to the buffer provided in the bridge device, and the other one which is about to read data from the storage area of the host controller for the rebuild process is caused to read the data from the buffer.

Printer apparatus and control method of printer apparatus

An apparatus is provided for setting a printing fee based on the result of image analysis. The apparatus determines whether an input image is color or monochrome, obtains the color amount in the input image, performs image processing on the input image, prints the processed input image, and sets a fee for printing the input image based on the obtained color amount.

Apparatus, method, and program for setting printing fee based on image analysis result

An image processing apparatus includes a memory to store instructions, and one or more processors to execute the instructions and cause the image processing apparatus to function as a count unit and a determination unit. The count unit counts an image object of gray in an input image as a color pixel, wherein the count unit does not count an image object of white in the input image as a color pixel. The determination unit determines whether the input image is a color document based on a number of color pixels counted by the count unit.

Image processing apparatus and image processing method

An information processing apparatus performs data processing and includes a first device, a second device, and a power source unit to supply predetermined power. The first device includes a first communication unit that communicates with the second device, a first initialization unit that initializes the first communication unit with the supplied power based on a notification received from a second communication unit of the second device, a detection unit that detects the second device, and a transmission unit that transmits specific logical information to the detected second device. The second device stores the acquired specific logical information and includes a second initialization unit that initializes the second communication unit with the supplied predetermined power, and a third initialization unit that completes an initial setting of the second device by writing the specific logical information into storage based on the notification from the initialized second communication unit.

A printing apparatus includes white and gray text determination units and a setting unit to charge a color printing fee where a pixel for which a color printing flag is set is present in an input image, and to charge a black-and-white printing fee where a pixel for which the color printing flag is set is not present in an input image. The white determination unit determines whether a focused pixel in the input image is a white pixel. The gray text determination unit determines whether the focused pixel constitutes a gray text. Where the focused pixel is determined to constitute a gray text or be a white pixel, the setting unit sets a black-and-white printing flag for the focused pixel and, where the focused pixel is determined to neither constitute a gray text nor be a white pixel, the color printing flag is set for the focused pixel.

An information processing apparatus comprises: a programmable processing unit capable of changing a circuit configuration by a configuration; a first control unit connected to the programmable processing unit, that instructs the programmable processing unit to perform a first configuration for a first job to be processed by the first control unit, and processes the first job by means of the programmable processing unit which has changed the circuit configuration according to the instruction; and a second control unit connected to the programmable processing unit, wherein the first control unit further instructs the programmable processing unit to perform a second configuration for a second job to be processed by the second control unit, and wherein the second control unit processes the second job by means of the programmable processing unit which has changed the circuit configuration according to the instruction.
