A print media detection apparatus may include a movable scanner bar for scanning media, a feeder tray for supplying the print media, a print media indicator and a controller. The print media indicator may include a first portion to interact with the print media within the feeder tray and a second portion coupled to the first portion to move in response to movement of the first portion. The scanner bar is to sense the second portion of the media indicator. The controller is to determine a characteristic of the print media within the feeder tray based upon sensing of the second portion by the scanner bar.

A printing apparatus corrects image data for printing on the basis of a color measurement result obtained by a sensor, prints a set of first color tone correction patches on a first sheet with a predetermined size and prints a set of a second color tone correction patches on a second sheet with the predetermined size. When the first sheet and the second sheet are printed one after another, a color measurement result of the tone correction patches printed on the first sheet and the second sheet is used in correcting the image data for printing. When the first sheet and the second sheet with the predetermined size are not printed one after another, a color measurement result of the tone correction patches printed on the first sheet and the second sheet for correcting the image data for printing is not used in correcting the image data for printing.

Setting conditions related to reading of an image of a document are registered in association with a user according to input by a user. When a user is identified, the priority order is determined so that a setting condition corresponding to the identified user is prioritized over a setting condition not corresponding to the user among the registered setting conditions, and the setting condition information indicating the setting conditions in the determined priority is displayed. The image is read under the setting condition based on the setting condition information selected according to the input by the user of the setting condition information indicating the displayed setting conditions.

An image forming apparatus includes a sensor configured to detect a length of a sheet, which is placed on a platen, in a predetermined direction and a controller. The controller is configured to convert an image signal based on a conversion condition, control the image forming unit to form an image based on the converted image signal, and execute calibration in which the conversion condition is generated. The controller is configured, in a case in which the calibration is to be executed, to acquire information related to a size of a sheet on which a test chart is to be formed, select a sheet based on the information, form the test chart on the selected sheet acquire reading data output from the reader, and generate the conversion condition based on the reading data.

An image forming apparatus includes a document tray in which a document is to be set, a medium container that contains a recording medium, a document detection sensor that detects a document set in the document tray, a medium detection sensor that detects a recording medium contained in the medium container. A hardware processor executes a copy operation of forming an image obtained by scanning a document set in the document tray on a recording medium, determines to automatically execute the copy operation in case an elapsed period of time between a document detection time when a document is detected by the document detection sensor and a medium detection time when a recording medium is detected by the medium detection sensor is equal to or smaller than a predetermined operation period of time, and automatically executes the copy operation based on determination of automatic execution of the copy operation.

An image abnormality detecting device includes an image reader, an abnormality detector, a pattern holder, and circuitry. The image reader is configured to read an image on a recording medium. The abnormality detector is configured to detect abnormality of the image based on read information of the image on the recording medium, read by the image reader. The pattern holder has a check pattern and is disposed within a reading area of the image reader. The circuitry is configured to inspect a detecting operation of the abnormality detector based on read information of the check pattern read by the image reader.

The multifunction peripheral of the present invention includes an ADF document crop function. According to this ADF document crop function, front side image shaping processing for cutting out a front side document image corresponding to the image on the front side of a document, from a front side read image of the document and for correcting the tilt of the front side document image is performed. Then, on the basis of shaping information in the front side image shaping processing, back side image shaping processing for cutting out a back side document image from a back side read image of the document and for correcting the tilt of the back side document image is performed.

A printing apparatus causes a printer engine to print first tone correction patches of a first color on a first sheet and to print second tone correction patches of a second color being different from the first color on a second sheet, generate correction information based on a color measurement result of the first tone correction patches and the second tone correction patches printed on the first sheet and the second sheet, respectively, as measured by a sensor, and correct image data using the correction information. In the generation of the correction information, in a case where there are more than a predetermined number of sheets of a size being different from a predetermined size between the first sheet and the second sheet, the correction information using the color measurement result of the first tone correction patches and the second tone correction patches is not generated.

Systems and methods are provided for processing and extracting content from an image captured using a mobile device. In one embodiment, an image is captured by a mobile device and corrected to improve the quality of the image. The corrected image is then further processed by adjusting the image, identifying the format and layout of the document, binarizing the image and extracting the content using optical character recognition (OCR). Multiple methods of image adjusting may be implemented to accurately assess features of the document, and a secondary layout identification process may be performed to ensure that the content being extracted is properly classified.

There is provided an image reading device in which a controller is configured to perform detecting, by executing an edge detection process, edge pixels from image data scanned by a reading device and stored in a storage, the edge pixels being pixels obtained by reading an edge of an original document. Then, it is determined whether a sequence of the detected edge pixels in a particular direction is interrupted. When interrupted, an expansion process is executed to increase the edge pixels in a particular range in a neighborhood of the detected edge pixels of the image data. Then, a particular process is performed on the image data using the edge pixels detected from the image data after the edge pixels are increased.
