An image processing apparatus is provided which can perform image recovery processing with high accuracy. The image processing apparatus acquires first image data from a first imaging element configured to receive a first light flux as a result of a division of light performed by an optical element, acquires second image data from a second imaging element configured to receive a second light flux as a result of the division of the light performed by the optical element, performs image recovery processing on the first image data by using a first image recovery filter generated based on information relating to an optical transfer function of the first light flux, and performs image recovery processing on the second image data by using a second image recovery filter generated based on information relating to an optical transfer function of the second light flux.

A guidance method includes an execution step of executing a control command processed when an operation of a user or an event such as malfunction occurs, a generation step of generating control information regarding the control command, a notification step of notifying the control information to the user, a setting step of setting mode information for at least one of a first mode in which the control information is notified, and a second mode in which the control command is executed, and a processing step of causing the control information to be notified in the notification step in a case where the first mode is set, and causing the control command to be executed in the execution step in a case where the second mode is set.

An electronic device includes an operation section, first storage, second storage, a processing section, and a display section. The first storage stores data of a file therein. The file includes contents that can be printed. When the operation section receives an instruction for erasing the file, the processing section transfers the file from the first storage to the second storage. The display section displays an inquiry screen for inquiring whether or not to reproduce the file. When the operation section receives an instruction for reproducing the file, the processing section executes print processing or transmission processing. The print processing is processing for printing the contents. The transmission processing is processing for transmitting an email with the file attached thereto. After executing the print processing or the transmission processing, the processing section erases the file from the second storage.

An image formation apparatus includes: an image formation unit that forms an image based on a job; and a control unit that controls the image formation unit, the control unit having an image quality verification/adjustment function to compare an image quality of the scanned image and a predetermined image quality standard, and to carry out an image quality adjustment such that the image quality of the image is within an allowable range of the predetermined image quality standard when the image quality of the scanned image is not within the allowable range, the control unit comparing a required image quality for the job and the predetermined image quality standard before a carrying-out procedure to carry out the image quality verification/adjustment function before execution of the job as necessary, and deciding whether the image for the job satisfies the required image quality by the image quality verification/adjustment function.

In an image forming apparatus, when a processor starts to be supplied with a voltage in a first voltage range from a voltage generator, the processor executes start-up processing with an operation clock of a first frequency, and transmits a voltage adjustment instruction to the voltage generator. On receiving the voltage adjustment instruction, the voltage generator performs voltage adjustment to make the voltage supplied to the processor a voltage in a second voltage range. On completion of the voltage adjustment, the voltage generator transmits a completion notice to the processor. When communication related to the voltage adjustment does not end normally, the processor keeps the frequency of the operation clock at the first frequency to execute processing; thereafter based on the operation clock of the first frequency.

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.

An image forming device includes: an image forming unit that forms an image on a transfer medium; and a controller that controls multiple image readers capable of performing image reading for the same surface of the transfer medium, and acquires reading results from the image readers. The controller is capable of performing failure/no-failure determination for the image on the transfer medium based on the reading results, of switching image reading by the multiple image readers between reading by a first number of image readers and reading by a second number of image readers, the second number being smaller than the first number, and of enabling, while the second number of image readers perform reading, at least one of the other image readers to execute a maintenance operation for the at least one of the other image readers.

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.

An image forming apparatus, guide providing method thereof, cloud server and error analyzing method thereof are provided. The image forming apparatus may include a scanner configured to scan a script and generate a scan image, a communicator configured to communicate with a cloud server, a display configured display a screen, and a processor configured to control the communicator to transmit the generated scan image to a cloud server, and in response to receiving an error solution guide of the scan image from the cloud server, control the display to display the received error solution guide.

In one embodiment, a control method for an image processing apparatus including a reading unit configured to read a document image and a printing unit configured to print the document image read by the reading unit is provided. The control method includes detecting an error in process of reading by the reading unit, causing the reading unit to perform reread processing for rereading the document image based on the error being detected, and refraining, in a case where the image processing apparatus operates in a mode in which the printing unit starts printing without waiting for the reading unit to complete reading a document image, from causing the reading unit to perform the reread processing based on the error being detected.
