An image diagnostic device comprising circuitry configured to output a diagnostic chart for image defect detection, read a predetermined reading range of the diagnostic chart, output a read image based on reading of the predetermined reading range, detect an image defect in the diagnostic chart based on the read image, and determine whether the image defect is at an end of the read image. In response to a determination that the image defect is at the end of the read image, the circuitry controls rereading to read a rereading range of the diagnostic chart different from the predetermined reading range.

A display control apparatus is configured to display on a display unit a user interface screen for an image data generating apparatus configured to generate image data using an image sensor. The display control apparatus includes a setting acquiring unit which is configured to acquire a setting value for generating the image data, a display determining unit which is configured to determine whether to display an update reception screen based on the acquired setting value, a display control unit which is configured to display the update reception screen on the display unit if the display determining unit determines to display the update reception screen, and is configured not to display the update reception screen on the display unit if the display determining unit determines not to display the update reception screen, and an instruction receiving unit which is configured to receive the update instruction through the update reception screen.

An inspection system includes: an inspection part that compares a scanned image obtained by scanning a sheet on which an image is formed on the basis of a job with a reference image prepared in advance and thereby performs inspection of the scanned image; and a hardware processor that sets an inspection target page to be a target of inspection and a non-inspection target page to be excluded from inspection, for the job, wherein the hardware processor causes the inspection part to perform inspection for the inspection target page and not to perform inspection for the non-inspection target page on the basis of the setting of the hardware processor, and the hardware processor creates an inspection report including scanned images of all pages of the job including the non-inspection target page.

If elements (curves) of a tone reproduction curve increase application of marking material, the magnitudes of the elements of the tone reproduction curve are summed. If the summed magnitudes of the elements of the tone reproduction curve exceed marking material limits, a warning message is output.

Systems, apparatuses and methods are provided to allow for detection of an impact to an output apparatus. Such impact may be caused by a sudden force applied to one or more points on the apparatus housing or another part of the apparatus accessible from outside the apparatus housing. An impact detector outputs to an apparatus controller an impact report including impact time and impact data corresponding to the detected impact event.

An image processing system includes a reading unit, a checking unit, a display control unit, and an image correcting unit. The reading unit reads image information from an original manuscript to generate image data. The checking unit checks whether or not a plurality of items listed in the original manuscript include an unentered item with the result of a character recognition process for recognizing a character contained in the image data. When the unentered item is present, the display control unit performs control to display information for informing a user of the unentered item. The image correcting unit adds a text with respect to the unentered item according to an input made by a user to correct the image data.

There is provided with an information processing apparatus. A first obtaining unit obtains data of a reference image indicating a target of printing output to be performed by a printing apparatus. A second obtaining unit obtains data of an image printed by the printing apparatus. A correcting unit corrects a local image density difference or the reference image based on a global image density difference between the reference image and the printed image. An evaluating unit evaluates quality of the printed image based on the local image density difference between the corrected reference image and the printed image.

Embodiments of the present disclosure provide an image calibration method, an image forming apparatus, and a storage medium. The method includes outputting a calibration image in response to a calibration instruction, where the calibration image includes a calibration pattern and a calibration mark; according to the calibration mark of the calibration image, determining whether a calibration event corresponding to the calibration image matches a calibration event corresponding to a current calibration operation, or determining whether a calibration event type corresponding to the calibration image matches a calibration event type corresponding to a current calibration operation; and performing image calibration according to the calibration pattern in the calibration image if the calibration event corresponding to the calibration image matches the calibration event corresponding to the current calibration operation, or if the calibration event type corresponding to the calibration image matches the calibration event type corresponding to the current calibration operation.

An electronic device that checks a connected state of a signal line is provided. The electronic device includes a controller configured to transmit a check signal and at least one module configured to include a closed loop and receive the check signal. When the controller receives the check signal through the closed loop, the controller determines that the at least one module is connected to the controller.

At the time of registering an image in units of documents, which is obtained by performing multi-cropping processing for a scanned image, and value information extracted from each image in a database in association with each other, there is a case where it is not possible to extract the value information successfully because of an overlap between documents during a scan. In a case where this fact is noticed after registration, it becomes necessary for a user to perform the entire work from the beginning. In a case where there is a possibility that the value information is hidden by an overlap between documents during a scan or the like, a display is produced for prompting a user to scan the document again.
