An image processing device capable of assigning a basic function and a server function to hardware resources and operating the basic function and the server function, includes: a hardware processor that: detects occurrence of a failure related to the basic function or transition to a power saving mode; releases a specific hardware resource corresponding to a function that has become inoperable due to the occurrence of a failure or the transition to a power saving mode, of the basic function assigned to the hardware resources, in a case where the occurrence of a failure or the transition to a power saving mode has been detected by the hardware processor; and additionally assigns the server function to the specific hardware resource released by the hardware processor, of the hardware resources, to operate the server function.

An image processing apparatus includes a reading device and at least one processor. The reading device reads a document into image data of a document image with a first resolution and a second resolution that are different from each other. The first resolution is used for reading the document in a main scanning direction. The second resolution is used for reading the document in a sub-scanning direction perpendicular to the main scanning direction. One or more processors detect an inclination angle of the document image corresponding to inclination of the document, obtain a distortion angle of the document image based on the inclination angle and a ratio between the first resolution and the second resolution, and correct distortion of the document image using the distortion angle.

Methods and apparatus for predicting colorant usage by printing devices are provided. A prediction server can receive a request to predict colorant usage for a first printing device. The prediction server can determine first plurality of functions to predict colorant usage for the first printing device. The first plurality of functions can include at least one linear function and at least one non-linear function. The first plurality of functions can be based on colorant-usage rates indicating historical rates of change in colorant used by the first printing device. The prediction server can determine a prediction of colorant usage for the first printing device using the first plurality of functions. The prediction server can provide an output involving the prediction of colorant usage for the first printing device, where the prediction of colorant usage can include a confidence interval related to the prediction.

A remote maintenance system is provided that makes it easy to comprehend support received from an operator. In this system, an image forming apparatus receives an image of the image forming apparatus that is photographed by a mobile terminal from the mobile terminal, transmits the image of the image forming apparatus to an operator terminal, receives support information from the operator terminal, and transmits the support information to the mobile terminal. The mobile terminal photographs the image forming apparatus, transmits the photographed image of the image forming apparatus to the image forming apparatus, receives support information from the image forming apparatus, and based on coordinate information included in the support information, superimposes and displays a guide image included in the support information and the photographed image of the image forming apparatus.

An original image is read as an aggregate of a plurality of pixels in which adjacent pixels have different colors (R, G, and B) in a main scanning direction and in a sub-scanning direction, and the read pixels of the respective colors are stored in a line memory in association with information on relative positions of the pixels with respect to another pixel. Then, the stored pixels are sorted so that pixels having the same color are adjacent to each other, and an abnormal pixel (dust) not present in the original image is detected based on the state of the sorted pixels. With this, the dust not present in the original image is detected without increasing the cost, and the dust is corrected without forming a conspicuous trace of correction.

A reference image of an image capture device is processed to detect multiple image flaws caused by defects or corruption items of the image capture device(510). Data corresponding to an image map of flaws for the image capture device are stored (520). For subsequent images, flaws in the captured image are corrected using the image map of flaws (530).

Provided is an information processing apparatus including a first processing unit and a second processing unit. A diagnosis unit included in the first processing unit is configured to detect that communication of first information through a communication line is not performed properly, the communication of the first information being performed between a first CPU in the first processing unit and a second CPU in the second processing unit. A switch unit included in the second processing unit is configured to switch information to be transmitted through the communication line from the first information to second information in a case where it is detected that the communication of the first information through the communication line is not performed properly, the second information being transmitted to the diagnosis unit included in the first processing unit from a diagnosis unit included in the second processing unit.

An image forming apparatus including: a hard disk configured to store data; a hard disk malfunction detecting unit configured to detect malfunction of the hard disk; a partition confirmation unit configured to determine as to whether a malfunctioning portion of the hard disk is in a preliminary determined partition; and a partition formatting unit configured to format the partition, wherein, when the malfunctioning portion of the hard disk detected by the hard disk malfunction detecting unit is determined as being in the partition preliminary determined by the partition confirmation unit, the partition formatting unit formats the partition.

An image reading apparatus reads an original image of an original, which is conveyed along a conveyance path, using a scanner unit and a CCD sensor unit. A separation sensor, a lead sensor, and a sheet discharge sensor, which are provided to the conveyance path, detect occurrence of a jam. A restarting method for reading processing of the original after the occurrence of the jam includes a first restarting method of re-placing all of the originals, which have been fed, on an original tray and a second restarting method of re-placing only an unread original on the original tray, and is set by a user. In a case where the second restarting method is set, the restarting method is determined from any one of the first restarting method and the second restarting method based on a discharged length of the original having been discharged to a sheet discharge tray.

A system and method for managed device data collection includes a data collector controller for control of monitoring activity of networked multifunction peripherals. A user interface includes a display rendering a plurality of processor rendered interactive user configuration screens. Displayed configuration screens solicit and receive corresponding user input. The configuring screens facilitate setting device user interaction including setting a network address, network connectivity testing, modification of device certificates, changing network settings, and a testing discovery, registration or data transfer mechanism for multifunction peripheral device data collection. A data storage stores user selection data received via rendered configuration screens and the processor outputs stored user selection data as configuration data for data collection from the multifunction peripherals.
