An inspection device includes an image reader that generates a scan image, an inspector that inspects an inspection target image formed on a storage medium, by comparing a scan image with a reference image, a storage that stores the reference image, and a hardware processor that stores into the storage the reference image generated as the scan image by reading with the image reader an image formed on a recording medium by the image former on a basis of a second print job for generating the reference image, determines whether the reference image stored in the storage satisfies a predetermined condition when a data amount of the reference image stored in the storage becomes equal to or larger than a predetermined amount, and deletes the reference image determined to satisfy the predetermined condition from the storage.

Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

There is provided an inspection device that performs quality inspection of a printed matter, the inspection device including: a first hardware processor that obtains a document image; a first reader that reads the printed matter obtained by forming a printed image on one surface of a transparent material based on the document image from a side of the other surface opposite to the one surface; and a second hardware processor that detects an abnormality of the printed matter based on the document image and a read image by the first reader.

Provided is an image forming apparatus that speeds up the auto color mode. The image forming apparatus includes a document reading unit that reads a document including a plurality of pages and outputs image data and can determine whether the document is a color document or a monochrome document. In the document read by the document reading unit, when monochrome pages of the first specific number of pages or more continues in the same job, a document determining unit predicts that the subsequent page is also determined to be a monochrome document. When the document is predicted by the document determination unit to be a monochrome document, an image processing unit performs monochrome image processing for the monochrome document on the image data immediately after reading.

A printed-matter inspection system includes a processor for evaluating quality of printed matter, and a display apparatus. The processor is configured, by reading a program for execution, to: for each of multiple pages in a job, if the page is an inspection target, compare, for inspection, a scanned image with a reference image, the scanned image being obtained through scanning of printed matter in the page, the reference image being generated by using rasterized data for the page; and, in display of the result of the inspection on the display apparatus, display the scanned image for the page that is an inspection target, and display, for a page that is not an inspection target, a dummy page and information indicating that the page is not an inspection target, the dummy page being a substitute of the scanned image.

A reading device and an image forming apparatus are provided. The reading device includes an image reading device configured to read an image on a recording medium being conveyed, a background device serving as a background image when the image is read by the image reading device, and a foreign-object detector configured to compare a first read image obtained as the background device is read by the image reading device with a second read image obtained as the background device and the recording medium are read by the image reading device to detect an attached foreign object. The image forming apparatus includes the reading device and an image forming device.

An example of an apparatus including a communication interface to receive an image file is provided. The image file represents a scanned image of a output generated by a printing device. The apparatus further includes an identification engine to process the image file with a convolutional neural network model to identify a feature. The feature may be indicative of a potential failure. The apparatus also includes an image analysis engine to indicate a life expectancy of a part associated with the potential failure based on the feature. The image analysis engine uses the convolutional neural network model to determine life expectancy.

An inspection device includes an image reader that generates a scan image, an inspector that inspects an inspection target image formed on a storage medium, by comparing a scan image with a reference image, a storage that stores the reference image, and a hardware processor that stores into the storage the reference image generated as the scan image by reading with the image reader an image formed on a recording medium by the image former on a basis of a second print job for generating the reference image, determines whether the reference image stored in the storage satisfies a predetermined condition when a data amount of the reference image stored in the storage becomes equal to or larger than a predetermined amount, and deletes the reference image determined to satisfy the predetermined condition from the storage.

There is provided an information processing device including an information acquisition unit that acquires camera location information indicating locations of a plurality of imaging cameras located in an imaging space, and an evaluation unit that acquires calibration accuracy obtained in a case of locating a calibration camera in the imaging space on a basis of the location of each of the plurality of imaging cameras indicated by the camera location information and a location of the calibration camera.
