Abstract: An image reading apparatus controls a sheet feeding unit such that in a reading job in which a plurality of documents on a document tray is continuously fed, continuous feeding of the documents is stopped in response to changing of a detection state in which a document is detected on the document tray to a non-detection state in which no document is detected on the document tray. The control unit executes a first mode in which the sheet feeding unit stops the continuous feeding of the documents in a case where the number of documents having been discharged continuously in the reading job has reached a predetermined number of sheets, regardless of a detection result of the detection unit, and a second mode which continues the continuous feeding of the documents regardless of the number of documents having been discharged continuously.

Abstract: An image reading apparatus that makes it possible to reduce the influences of dirt on a white reference chart itself, stripes caused by dust, and the like, and thereby generate accurate data for shading correction. An image processor performs shading correction on image data read by a reader unit. The read image data is compared with threshold values set for each pixel, and a pixel which is out of a range of the threshold values is determined as a singular point pixel. Data of a pixel determined as a singular point pixel is interpolated from data around the singular point pixel. Data of a pixel which is not determined as a singular point pixel is adopted as valid shading correction data. An operation controller controls the number of effective sampling lines from start to termination of sampling to be performed.

Abstract: An operational imaging device and method for sensing a media type in a predetermined media set using a predetermined set of media type determining equations solved using measured values for a set of N variables measured by an operational sensor set in the operational imaging device. The solution of the equation set determines a media type. After a media type is determined, one or more operational parameters of the imaging device is selected for processing of a sheet of the determined media type. The equation set is generated by a training system using a classifier training engine. A plurality of training data sets containing measured variable values for each media type is collected under various conditions by a training sensor set that measures the set of N variables. After generation, the media type determining equation set is stored in memory of the operational imaging device.
